Description

The present invention relates to a super-abrasive grinding wheel in which abrasive grains are attached to the outer peripheral surface of a cylindrical body serving as a base, and in particular, the cylindrical body is an empty can-shaped cylindrical body formed of a thin wall, and a large number of the outer peripheral surface and the side surface thereof. It relates to an empty can type cylindrical grinding wheel in which holes are formed and superabrasive grains are electrodeposited, and a method for manufacturing this grinding device and an empty can type cylindrical body.

In recent years, a grinding wheel has been developed in which a grinding wheel having pores of about Φ0.5 mm radially about 1,000 or more from the center of rotation is passed through a grinding wheel made of a metal base metal.
Further, a grinding wheel has been developed in which a grinding wheel having a width of 0.3 mm is provided at 120 places on the outer circumference of a metal base metal so that a grinding fluid reaches a processing point and passes through each groove in the grinding wheel.
After electrodeposition processing of superabrasive grains on the base metal with finely processed pores or grooves, mask removal is indispensable, and high production cost and long production time are indispensable. Therefore, the current situation remains that it is not widely used as a grinding wheel. It is in.

In addition, another grinding wheel is an improved grinding tool that enhances the holding power of abrasive grains, extends the service life, improves the elimination of cutting chips, and enables high-precision machining at high speed. .. More specifically, the surface of the tube 1 in which fibers such as carbon, glass, ceramics, thermosetting resin, and metal are formed in a multi-layered porous manner by weaving, knitting, or non-weaving from inside the porous holes. The abrasive grains 2 are fixed to the glass. Adhesion is by electroplating, electroless plating, PVD, CVD vapor deposition, or laser welding. A grinding member made of a tube 1 to which the abrasive grains 2 are fixed is fixedly attached to the shank 3, and the shank 3 has a coolant supply hole 3a on the central axis and an opening 3b formed in the fitting portion of the tube 1 to be porous. Some are made so that the coolant can be ejected from the hole 1a of the quality tube (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 5-208371

The grinding tool in JP-A-5-208371 is made of carbon, glass, ceramics, thermosetting resin, metal, and other fibers formed into a multi-layered porous tube 1 by weaving, knitting, or non-weaving. Abrasive grains 2 are fixed from the inside of the quality hole to the surface. As a result, a grinding member made of a tube 1 to which the abrasive grains 2 are fixed is fixedly attached to the shank 3, and the shank 3 is formed with a coolant supply hole 3a on the central axis and an opening 3b at the fitting portion of the tube 1. , The coolant can be ejected from the hole 1a of the porous tube. However, since the abrasive grains 2 are fixed to the surface of the outer peripheral surface of the grindstone from the inside of the porous hole, the hole becomes a narrow gap, which causes the hole to be clogged in a short period of time, and the initial coolant is ejected. Is pointed out as a problem that it cannot be maintained.

In addition, a grinding wheel that allows the grinding fluid to reach the processing point from inside the grindstone that has about 1,000 or more pores of about Φ0.5 mm radially from the center of rotation on the metal base, and the outer circumference of the metal base. The grindstone, which has 120 grooves with a width of 0.3 mm and allows the grinding fluid to reach the machining point from each groove in the grindstone, has a heavy base metal and high rigidity. Since there is a possibility of forcibly rubbing the ground surface with the superabrasive grains of the base metal, which is a highly rigid body, distortion and surface roughness appear on the ground surface, and there is a problem that the product becomes a defective product with insufficient accuracy.

As described above, the inventor of the present application causes the grinding fluid (hereinafter, also referred to as coolant) to arrive at the processing point from the inside of the grindstone having about 1,000 or more pores of about Φ0.5 mm radially from the center of rotation in the base metal. A grinding wheel or a grinding wheel that allows the grinding fluid to pass through each groove in the grinding wheel provided with 120 grooves having a width of 0.3 mm on the outer circumference of the metal base metal. Furthermore, in view of the problems of porous cyclic grindstones and the like, we tried to develop a new grinding wheel.
Therefore, paying attention to the drawback that the grinding wheel forcibly rubs against the ground surface of the workpiece to be ground with the super-abrasive grains of the base metal, which is a highly rigid body, appears as distortion or surface roughness on the ground surface.

An example of processing by a grinding device 100 (not shown in detail) in which the empty can type cylindrical grinding wheels K1 to K10 are attached to a rotating shaft S which is a main shaft of the grinding machine 100 will be described subsequently. In FIG. 7, the mounting states of the grinding wheels K1 to K10 on the center-through type rotating shaft S and the mounting states of the grinding wheels K1 and K2 on the rotating shaft S1 of the external nozzle N will be described. FIG. 7A shows a state in which the empty can type cylindrical grinding wheels K1 to K10 are mounted on the center-through type rotating shaft S, and the open side surfaces 10C and 11C of K1 and K2 are mounted on the outside.
FIG. 7B shows a state in which the empty can type cylindrical grinding wheels K1 and K2 are attached to the rotating shaft S3 of the external nozzle N with the open side surfaces 10C and 11C facing inside. FIG. 7C shows a state in which the empty can type cylindrical grinding wheels K3 to K10 are mounted on the center-through type rotating shaft S with the mounting holes S1 inside.

FIG. 13 shows an open type mounting device in which the empty can type cylindrical grinding wheels K1 and K2 are mounted on the rotating shaft S3 of the external nozzle N shown in FIG. 7A with the open side surfaces 10C and 11C facing inside. That is, the rotary shaft S is tightened to the center-through tool holder H0, the coolant liquid CK is supplied into the empty can type cylindrical grinding wheels K1 and K2, and is ejected from the small hole h or the slit L toward the grinding surface KM. A side nozzle N is installed as an auxiliary.

The empty can type cylindrical grinding wheels K1 and K2 with the one side surfaces 10C and 11C open are attached to the center-through type rotating shaft S in FIG. 7A and the side surfaces as shown in FIG. 7B. The nozzle N is attached to the rotating shaft S3. To supply the grinding fluid CK to the rotating shaft S and the side nozzle N, the pulsating pressure or non-pulsating pressure coolant CK from the coolant supply device 50 shown in FIG. 10 is applied to each empty can type cylindrical grinding wheel [K1 to K10]. It is to supply. The coolant supply device 50 includes a two-cylinder plunger pump P (single cylinder AC, BC) that supplies the coolant liquid CK in the tank T by the motor MO of the drive source, and a coolant having a pulsating pressure discharged from the plunger pump P. It is provided with check valves V1 to V5 for switching the liquid CK in various ways. By switching the check valves V1 to V5, a path for piping and supplying four types of coolant liquid CK to each empty can type cylindrical grinding wheel K1 to K10 is formed. The coolant liquid CK to be discharged is the combined pressure (P1 + P2) P3 of the single cylinder AC, the pressure P2 of the single cylinder BC, and the combined pressure (P1 + P2) P3 according to the NC control program PG from the NC control device 60. P1 + P2) P3 is put into the accumulator AQ to switch to four types with a constant pressure P0.

Then, as shown in FIGS. 3 to 4 and 7 (a), in the empty can type cylindrical grinding wheels K1 to K4 in which the superabrasive grains 13 are fixed to the outer peripheral surfaces 10A, 11A, 20A, 21A. When any of the pressure P1 of the single cylinder A, the pressure P2 of the single cylinder B, the combined pressure P3 of both, or the constant pressure P0 by the accumulator AQ is supplied from the coolant supply device 50 of FIG. Grinding liquid (also referred to as coolant liquid) CK is sprayed onto the grinding surface KM from innumerable small h holes or slit holes L, and is lightly ground by the superabrasive grains 13. That is, the basic grinding action of grinding the ground surface with the super-abrasive grains 13 of the outer peripheral surfaces 10A, 11A, 20A, 21A by washing away the grinding dust and abrasive grains peeled off by the grinding liquid CK which is static pressure or pulsating at the time of grinding. Will be carried out. The weight of the empty can-shaped cylinders 10, 11, 20, and 21 as the base metal is very light, and the outer peripheral surfaces 10A, 11A, 20A, and 21A of the empty can-shaped cylinder are supple with respect to the grinding surface KM of the work to be ground. A highly accurate ground surface or polished surface can be obtained by the flow of the grinding fluid CK without causing distortion or surface roughness without generating heat on the ground surface.

Further, as shown in FIG. 7B, when the grinding fluid CK is injected inward from the nozzle N from the open side of the empty can-shaped cylindrical bodies K1 and K2, innumerable small h holes or slit holes on the outer peripheral surface are formed. The grinding fluid CK can be lightly ground with superabrasive grains while being evenly sprayed from L onto the grinding surface KM. That is, when any of the pressure P1 of the single cylinder A, the pressure P2 of the single cylinder B, the combined pressure P3 of both, or the constant pressure P0 by the accumulator AQ is supplied from the coolant supply device 50, the outer peripheral surface is innumerably small. The grinding fluid CK is sprayed onto the grinding surface KM from the h hole or the slit hole L while being lightly ground by the superabrasive grains 13. As a result, a highly accurate ground surface or polished surface can be obtained by the flow of the grinding fluid without generating heat on the ground surface and causing distortion or surface roughness.

Further, the empty can type cylindrical grinding wheels K3 to K10 composed of the empty can-shaped cylindrical bodies 20 and 21 of FIGS. 4 and 5 are attached to the center-through type rotary shaft S as shown in FIGS. 7 (c) and 11 (a). It will be installed. Then, the coolant liquid CK discharged from the coolant supply device 50 is switched by selecting and switching the pressure P1 of the single cylinder A, the pressure P2 of the single cylinder B, the combined pressure P3 of both, the constant pressure P0 by the accumulator AQ, and the like. The coolant liquid CK having a pulsating pressure P1, P2, P3 to a non-pulsating pressure P0 is injected into the empty can-shaped cylinder. As a result, the grinding fluid CK is evenly sprayed onto the grinding surface KM from the innumerable small h holes or slit holes L on the outer peripheral surface, and the super-abrasive grains 13 are lightly ground. Therefore, the ground surface KM can obtain a highly accurate ground surface and polish by the flow of the grinding fluid CK without generating heat and causing distortion and surface roughness.

The mounting device shown in FIG. 7 (c) is shown in FIG. That is, the rotary shaft S is tightened to the center-through tool holder H0, the coolant liquid CK is supplied into the empty can type cylindrical grinding wheels K3 to K10, and is ejected from the small hole h or the slit L toward the grinding surface KM.
Further, the mounting devices in FIGS. 5 (a), (b) and (c) and 11 (b) and (c) are shown in FIGS. 14 and 15. That is, the rotary shaft S is tightened to the center-through tool holder H0, the coolant liquid CK is supplied into the empty can type cylindrical grinding wheels K3 to K7, and the coolant liquid CK protrudes from the small hole of the rubber thin film material G or the non-woven fabric W toward the grinding surface KM. It is sprayed.

By the way, as shown in FIG. 11B, a rubber thin film material G is lined on the inner wall surface of the empty can type cylindrical grinding wheels K3 to K7, and diamond, CBN electrodeposited abrasive grains or WA are formed on the surface of the rubber thin film material. When any of the GC abrasive grains 11 is fixed, the coolant liquid CK discharged from the coolant supply device 50 is the pressure P1 of the single cylinder AC, the pressure P2 of the single cylinder BC, the combined pressure P3 of both, and the accumulator. It is switched to any of the constant pressure P0 by AQ. When the rubber thin film material G is built in, the rubber can be selected from the pressure P1 of the single cylinder AC, the pressure P2 of the single cylinder BC, the combined pressure P3 of both, and the constant pressure P0 by the accumulator AQ. The thin film material G is expanded. Now, as shown in FIG. 11B, the rubber thin film material G has innumerable small holes or slit holes formed on the outer peripheral surface by, for example, pressurization P0 of the coolant liquid CK flowing into the empty can-shaped cylinder. The bulging surface is lightly ground by the superabrasive grains 13 on the outer peripheral surface of the bulging rubber thin film material G. As a result, a highly accurate ground surface can be obtained without causing distortion or surface roughness on the ground surface KM like a balloon grindstone. Further, a part of the coolant liquid CK accumulated inside is ejected from a large number of small holes h1 formed in the rubber thin film material G from a bulging portion to lightly lubricate the ground surface. At this time, according to any of the pressure P1 of the single cylinder AC, the pressure P2 of the single cylinder BC, and the combined pressure P3 of both, the rubber thin film material G has a bulge amount from the small hole h or the slit hole L to the outer diameter side. The injection amount of the coolant liquid from the small hole h1 fluctuates and pulsates, and a smoother polishing action can be obtained.

That is, when the coolant liquid CK discharged from the coolant supply device 50 is selected as the pressure P1 of the single cylinder A, the pressure P2 of the single cylinder B, and the combined pressure P3 of both, the small hole h or the slit hole L like a balloon grindstone. A part of the rubber thin film material G bulges toward the outer diameter side, and a highly accurate ground surface whose bulge amount pulsates can be obtained. Therefore, the coolant liquid CK is injected from the external nozzle N to swell the ground surface KM. However, it does not generate heat, and a highly accurate ground surface or polished surface can be obtained by the flow of the grinding fluid without causing distortion or surface roughness.

Therefore, in each of the empty can type cylindrical grinding wheels K3 to K7, when only the small holes h or the slit L are formed, the coolant liquid CK having various discharge pressures is discharged from the small holes h or the slit L to the grinding surface KM. Be jetted. At this time, when a pulsating pressure or non-pulsating pressure coolant liquid is supplied into the empty can-shaped cylinder, the abrasive grains staying on the grinding wheel and the grinding surface KM of the work are positively washed away by the pulsating pressure or non-pulsating pressure coolant liquid. Is done. As a result, there is no scratch on the ground surface due to the abrasive grains 13, and a honing surface and a polishing surface can be obtained from the efficiently and highly accurate ground surface. That is, the cooling of the ground surface polished by the abrasive grains, the discharge of the separated abrasive grains, and the cooling effect of the ground surface and the abrasive grains can be obtained.

Further, when the rubber thin film material G lined on the inner wall surface of the empty can-shaped cylinders K3 to K7 is used, when the coolant liquid CK is press-fitted into the blockage of the empty can-shaped cylinder, the outer peripheral surface of the empty can-shaped cylinder is small. The rubber thin film material G lined on the inner wall surface of the hole h or the slit hole L is moved from the innumerable small holes or slit holes formed on the outer peripheral surface to the outer diameter side by the pressurization of the coolant liquid CK flowing into the empty can-shaped cylinder. It swells, and the superabrasive grain 13 on the outer peripheral surface of the swelled rubber thin film material can grind the ground surface KM by gently stroking it. Thus, unlike a balloon grindstone, a honing surface and a polishing surface can be obtained from high-precision grinding without causing distortion or surface roughness on the ground surface. When the abrasive grains are kneaded and contained inside the rubber thin film material, new abrasive grains are exposed from the inside of the rubber thin film material even if the abrasive grains are worn off, and the polishing power is maintained.

Further, not only the rubber thin film material G but also the non-woven fabric W in which diamond abrasive grains and the like are woven as shown in FIG. 11C, the coolant liquid CK pops out from the mesh or the hole by this water pressure, and the polishing process and the wrapping process can be performed. It is possible and dramatically improves the surface roughness of the ground surface. At this time, the coolant liquid is switched to the pressure P1 of the single cylinder AC, the pressure P2 of the single cylinder BC, the combined pressure P3 of both, and the constant pressure P0 by the accumulator AQ by the NC control program PG from the NC control device 60. From grinding to polishing required by the ground surface KM, a wide variety of delicate ground surface can be obtained.

As shown in FIGS. 6A, 6B, and 6C, the empty can type cylindrical grinding wheel K8 is provided with grindstones 13 on the side surface 30B, and further, a grindstone K9 and a diamond having a rubber thin film material G inside. The above-mentioned action can be similarly obtained in the grindstone K10 which employs the non-woven fabric W in which the abrasive grains and the like are woven. For example, when the coolant liquid CK discharged from the coolant supply device 50 is selected as the pressure P1 of the single cylinder A, the pressure P2 of the single cylinder B, and the combined pressure P3 of both, it looks like the balloon grindstone shown in FIG. 11B. A part of the rubber thin film material G bulges from the small holes or slit holes to the outer diameter side, and the polishing surface is obtained from a highly accurate ground surface in which the amount of swelling pulsates. Further, if the non-woven fabric W is used, the coolant liquid CK jumps out from the mesh or the hole by this water pressure, and the polishing process and the lapping process can be performed, and the surface roughness of the ground surface is dramatically improved.

Further, as shown in FIG. 8, the empty can type cylindrical grinding wheels K1 and K2 have the rotating shaft S3 fitted in the mounting holes S1 provided on the side wall of the empty can-shaped cylindrical body, and inside the empty can-shaped cylindrical bodies 10 and 11. A ring-shaped sensor unit SU is fitted to the rotating shaft S of the above. The sensor unit SU includes a heat sensor HS, a vibration sensor SS, a memory M, a transmitter / receiver R, a power supply P, and a self-supporting annular body including a calculation CPU. Then, the grinding status by the empty can type cylindrical grinding wheels K1 and K2 is directly transmitted to the external monitoring device MU, and the optimum grinding action and the grinding result can be efficiently obtained while proceeding with the grinding process.

Further, as shown in FIG. 9, the empty can type cylindrical grinding wheels K1 and K2 are also used in a grinding method and a grinding device using a foamy coolant liquid CK, for example, when polishing a curved surface of a turbine blade TB. This is called three-dimensional free-form surface machining, and it is possible to polish a curved surface with ultra-high precision by cold air (foam) grinding. The means is that the rotating shaft S3 is fitted into the mounting hole S1 provided on the side wall of the empty can-shaped cylinder, and the coolant nozzle N is arranged outside the open one side surface of the empty can-shaped cylinder, and the coolant nozzle is used to form an empty can. The pulsating pressure or non-pulsating pressure coolant liquid CK from the coolant supply device 50 is supplied into the cylinder so that it can be injected. Further, the coolant liquid is made into a foamy coolant liquid, and the air in the atmosphere is supplied from a cooler having cold air of 0 ° C. or lower.

Alternatively, WA and GC abrasive grains are fixed or kneaded and contained. Furthermore, by adopting a non-woven fabric W in which diamond abrasive grains and the like are woven instead of the rubber thin film material G, it is possible to bulge out from the hole like a balloon grindstone by the water pressure of the coolant liquid and perform polishing and wrapping processing. The surface roughness of the ground surface is dramatically improved. As a result, a highly accurate ground / polished surface can be obtained without causing distortion or surface roughness on the ground surface like a balloon grindstone.

In addition to the pressure P1 of the single cylinder AC, the pressure P2 of the single cylinder BC, and the combined pressure P3 of both, it is switched to the constant pressure P0 by the accumulator AQ, and there are various types from grinding to polishing required by the grinding surface. A variety of delicate ground and polished surfaces can be obtained.
