Definitions
- the present invention relates to a cutting tool, rotating or fixed, for machining elements made of hard and / or abrasive material, which tool consists of at least one active part having hardness properties and / or greater abrasion than that of the material to be machined, and a passive part intended to cooperate with a tool holder comprising a clamp.
- These plates are fixed by means of a solder, by a screw passing through it and screwing into the body of the tool, or by holding tabs, etc.
- the wafer Once attached, the wafer will be sharpened as needed to make it sharp.
- This type of well-known tool is intended to be placed between the jaws of a clamp or mandrel, defining in the center a bore over the entire height. The tool is then immobilized using a tightening nut or side screws, for example.
- the reservations made on the body of the tool are sources of defect, for example when the abrasive pads are brazed, because it does not control the thickness of the solder.
- small tools are difficult to achieve because there is no place to put one or more screws, one or more flanges and in the case of solder, it will not be precise enough.
- the object of the present invention is therefore to create a rotary or fixed cutting tool, of great precision, which will be intended for machining, plane milling, surfacing, drilling, etching, etc., and this from materials already existing and used precisely to make said insert inserts, and which consist of agglomerates of polycrystalline diamond (PCD), or cubic edge nitride (PCBN), or also of tungsten carbide (CW).
- PCD polycrystalline diamond
- PCBN cubic edge nitride
- CW tungsten carbide
- the invention relates to a cutting tool, rotating or fixed, for machining elements made of hard and / or abrasive material, consisting of at least one active part having hardness properties and / or of abrasion superior to those of the material to be machined, and of a passive part intended to cooperate with a tool-holder comprising a clamp, characterized in that the active part and the passive part of said tool are formed by a one-piece plate defining the two parts, obtained directly from a blank of predetermined constant thickness and hardness corresponding to that of the active part, so as to obtain a flat tool, and in that its passive part is elongate and of constant section, generally quadrangular, intended to cooperate with a housing of corresponding section of the clamp, wherein housing directly mounts the monobloc flat tool thus formed, for fixing by clamping in the pin this.
- the housing or sections which can be rectangular, trapezoidal, square, and its positioning in the clamp, it is possible to easily fit the flat tool, the cutting portion being positioned accurately, for example in the center or in the transverse axis, or other.
- the cylindrical intermediate body of the tool, carbide or steel according to the prior art is removed to make room for a non-cylindrical monobloc tool obtained directly by cutting into a blank of an agglomerate of the aforementioned type, so flat.
- the invention will find application in the industry for the machining of very abrasive materials such as aluminum, titanium, carbon in its various forms, glass filled plastic, bakelite, gold, wood ( medium), etc.

- Figures 31 and 32 show a tool, respectively seen in plan and end, according to Figures 21 and 22.
- the cutting tool 1, IA, IB, IC, ID which can be rotatable or fixed according to the applications, is intended for machining elements made of hard and / or abrasive material, consisting of at least a part active having properties of hardness and / or abrasion greater than those of the material to be machined, and a passive part intended to cooperate with a tool holder 2 comprising a clamp 7.
- the active part "PA” and the passive part “PP” of said tool are formed by a one-piece plate defining the two parts, obtained directly at from a blank of predetermined constant thickness and hardness corresponding to that of the active part "PA”, so as to obtain a flat tool.
- the passive part "PP" of the same tool-plate is elongate and of constant section, generally quadrangular, intended to cooperate with a housing 3, 3A, 3B, 3C, 3D of corresponding section of the clamp 7, in which housing 3, 3A, 3B, 3C, 3D directly mounts the one-piece flat tool 1, IA, IB, IC, ID thus formed, for clamping in the clamp 7.
- the constituent material of the blank from which it is made is an agglomerated polycrystalline diamond (PCD) consisting of diamond powder and a cobalt binder, on a carbide base, the whole being compacted.
- PCD agglomerated polycrystalline diamond
- the constituent material of the blank from which the tool is made is a cubic edge nitride (PCBN).
- the constituent material of the blank from which the tool is made is a monobloc tungsten carbide (CW).
- the blank from which the tool is made is constituted by two layers 4.5, one neutral 4 constituting a support, the other abrasive being constituted by the PCD or PCBN deposited on one side of the support, to form a blank of desired thickness.
- the blank from which the tool is made consists of three layers 4.5.4, one central consisting of the PCD or PCBN, the other two 4 external, located on either side of the central layer 5 constituting carbide support, to form a blank of desired thickness.
- the tool-wafer is obtained directly from the blank, by cutting.
- FIG. 11 and 12 according to the first embodiment of the tool-plate 1, it is of generally quadrangular section, with bodies "d".
- the corresponding housing 3, comprising the same bodies, is made symmetrically or not to one of the axes XX 'of a clamp
- the same housing 3 is situated on one side of the other axis YY 'of the same clamp 7.
- the platelet tools IA are beveled at their active end and are housed, as previously, in quadrangular housing with bodies "d", but made on both sides of the axis XX ', and above and below the YY axis'.
- a central hole 8 is also provided in the clamp 7A, so as to insert a cylindrical guide member 9, a cylindrical drill bit, a cylindrical cutter or a tap.
- Lubrication holes 10 are provided to supply a lubricant during machining.
- the second embodiment shown in FIGS. 15 and 16 differs essentially in that reinforcing fins 11 are provided near the tool-inserts IA.
- FIGS. 17 and 18 implementing the tool-wafer IB in fact a flat drill, has a housing 3B perfectly centered along the axes XX 'and YY' of the clamp 7B.

- FIGS. 21 and 22 implementing a tool-plate ID in a 3D housing of the clamp 7D, said housing being centered along the axis XX 'and situated on one side of the YY axis'.
- the cutting part "c" of the tool-boards must of course be in the center and at the end of the drill. But it can be at the axis for the cutters or for any other housing positioned on demand on the clamp.
- the tool-wafer thus held in the clamp will be used for machining, rolling milling, surfacing, drilling, tapping, etching, especially with regard to the tool ID shown in Figures 21 - 22 and 31 - 32.
- the tool holder 2 for the implementation of a cutting tool 1, IA, IB, IC, ID which has just been described, consists, as can be seen in Figures 1 to 5, of: - a hollow cylindrical body 12 inside which is disposed a longitudinal stop 13 for the axial positioning adjustable depth of the tool 1, IA, IB, IC, ID, - a clamp 7 comprising jaws with conical clamping effect, by means of a clamping ring 14 exerting an action on the jaws, and consequently on the tool 1 once in place in - a housing 3, 3A, 3B, 3C, 3D of corresponding section, positioned between the jaws of the clip 7.
- tools-plates 1 may be adjustable to adjust the protruding part of the clamp
- the tools-plates can slide in their housing, which will allow to adjust them with a special stop at the desired height, out of the clamp 7.
- the clamps 7 will be adapted for each tool-plate 1 (housing 3, slots of the clamp, thrust stop 13, rear support).
- the clamps 7 may also include a reinforcement behind the projecting portion of the tool-plate; it will maintain and support the tool-plate during the work.
- the pusher portion of the stopper enters the clamp to have a passive zone as small as possible and reduce the cost of the tool.
- the pusher portion of the stops may be interchangeable, that is to say, it may be longer or shorter and more or less wide. It is maintained for example by a pin.
- the fine adjustment will be done by screws which are on the cylindrical body which carries the clamp 7.
- the body 12 and the clamp 7 can be made in one piece, and the adjustment screws positioned at the rear of the tool holder. Finally, with respect to the lubrication ports 10 being made through the clamp 7, these will be oriented to correspond to the most effective orientation for lubrication.
