The turning tool comprises a toolbar (4), at least one tool bit (1) arranged on the front end of the toolbar, a slab-shaped carbide alloy body (2) fixedly connected with the tool bit, and a slice-shaped composite poly-diamond blade (3) fixedly connected with the carbide alloy body. The tool bit (1) is arranged in a sunken bit seat (5) on the front end of the tool bar (4) and is pressed and fixed tightly by an upside pressure plate (6) and bolts (7) connecting the pressure plate and the toolbar. The rake angle of the turning tool is like: gamma <o> equal minus three degrees to ten degrees, the back angle is like: alpha <o> equal two degrees to twelve degrees, and the cutting edge inclination is like: lambada <s> equal minus three degrees to eight degrees. The utility model is suitable for working pieces for cutting ceramics and is particularly suitable for cutting insulating ceramics of processed electric appliance.
Description
Technical field
The utility model relates to the particularly cutter of pottery of cutting nonmetallic materials.
Background technology
The cutting of existing pottery forms processing, adopts the Carborundum wheel cutter, carries out grinding and is shaped.Because friction temperature height in the pottery cutting, and smear metal is Powdered and covers the cutting edge of parcel emery wheel, so processing difficulties, productivity ratio are extremely low.At the employing formed grinding wheel pottery is carried out the shape face especially and add man-hour, need often repair emery wheel, the service life of cutter is short.In addition, sneaked into the wearer of Carborundum wheel self in the ceramic material under the cutting, ceramic chip material can not recycling, and its economic loss is very big.
Existing metal cutting tool, as lathe tool, the monolithic construction that knife bar that useful high-speed steel is made and cutter head fuse, the setting type structure that adopts the affixed carbide chip of common metal cutter hub is arranged, the structure of gold bits ceramic welding on the car bar of utilizing high abrasion also arranged, and these lathe tools all are unsuitable for the high ceramic workpiece of cutting hardness.
The utility model content
Given this, the purpose of this utility model is to provide a kind of lathe tool that is suitable for the machining ceramic of machining ceramic, rate of cutting output height, long service life.
The utility model adopts insert hard alloy substrate on cutter head, the compound poly-diamond blade of insert on hard alloy substrate, and adopt a plurality of cutter heads of combination, select for use the tool orthogonal rake, relief angle, the cutting edge inclination that are suitable for machining ceramic to realize its purpose.
The lathe tool of machining ceramic of the present utility model (referring to accompanying drawing), comprise knife bar (4), at least one cutter head (1) of knife bar front end, the hard alloy substrate (2) that is fixed with plate shape on the cutter head, on hard alloy substrate, be fixed with the compound poly-diamond blade (3) of sheet shape, the anterior angle γ of lathe tool
0=-3 °～10 °, relief angle α
0=2 °～12 °, cutting edge inclination λ
s=-3 °～8 °.
Above-mentioned cutter head (1) be fitted in knife bar (4) front end in recessed tool tip (5), and use pressing plate (6) to be fixed up with the screw that is connected pressing plate and knife bar (7).
The thickness of above-mentioned compound poly-diamond blade (3) is 0.8～3mm.
The anterior angle γ of lathe tool
0Basic role be the cutting deformation that reduces workpiece, the processing work of this lathe tool is a pottery, therefore smear metal is a powder, needn't consider the cutting deformation problem of workpiece, when anterior angle increased, cutting edge was sharp, cutting and separating effect enhancing; Cutting lay extruding reduces, cut brisk, the raising of cutting surface quality.But edge strength reduces, and the heat radiation volume reduces, and the cutter wearability reduces.This lathe tool is γ preferably
0=0 °.
The relief angle α of lathe tool
0Very big to the friction effect between cutter and the workpiece.Increase relief angle, cutting edge is sharp, and friction reduces, but the intensity of cutting edge and heat-sinking capability reduce.This lathe tool is α preferably
0=6 °.
The cutting edge inclination λ of lathe tool
sRelevant with the intensity of the precision of lathe tool overall size and point of a knife.This lathe tool is λ preferably
s=0 °.
The utility model clamping is on lathe, and using method and common lathe tool are similar.
The utility model has following advantage and effect compared with prior art.
One, the dado head structure that hard alloy substrate, compound poly-diamond blade are arranged of the present utility model has high wearability, hear resistance, economy.Be suitable for machining ceramic material workpiece especially, the productivity ratio height of cutting, long service life.And the recyclable utilization of ceramic smear metal under the cutting, can reduce production costs significantly.
Two, the geometry of the anterior angle of lathe tool of the present utility model, relief angle, cutting edge inclination is suitable for the machining to the ceramic material workpiece especially, thereby can improve the productivity ratio of cutting, increases the service life of cutter.
Three, the multitool head combining structure on knife bar of the present utility model is simple in structure, assembles solid and reliablely, and the convenient mounting and clamping on lathe is rapid, helps improving rate of cutting output.
The utility model is applicable to the workpiece of machining ceramic material, is specially adapted to the insulating ceramics spare in the machining electrical equipment.
Below, the utility model is further described to use embodiment and accompanying drawing thereof again.
Description of drawings
Fig. 1 is the structural representation of the lathe tool of a kind of machining ceramic of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is that the A of Fig. 2 is to partial view.
Fig. 4 is to use the pottery tube workpiece of the lathe tool institute shaping by stock removal of a kind of machining ceramic of the present utility model.
The specific embodiment
The lathe tool of a kind of machining ceramic of the present utility model, as shown in drawings.Constitute by cutter head and knife bar.
Above-mentioned cutter head 1 selects for use common metal material to make cuboid as No. 45 steel.In the indentation of the step of cutter head front end, the hard alloy substrate 2 that welding is fixed with plate shape.Tungsten cobalt or kennametal that the material selection of hard alloy substrate is common.The thickness of sheet shape is arranged is the common compound poly-diamond blade 3 of 0.5～3mm to sintering on hard alloy substrate, and the thickness of the compound poly-diamond blade of present embodiment is about 1mm.
Above-mentioned knife bar 4 selects for use common metal material to make prolate side's bodily form as No. 45 steel.The knife bar front end is made the tool tip 5 to recessed breach step, and tool tip should be made and can be equipped with at least one above-mentioned cutter head 1.Present embodiment is made and can be equipped with four cutter heads.After packing into cutter head in the tool tip, above it with pressing plate 6, connect the screw 7 of pressing plate and knife bar, each cutter head 1 is pressed abd fixed in the tool tip 5.Constitute lathe tool of the present utility model.
During with this lathe tool turning pottery, adopt common cutting method to make blade, and the anterior angle γ of lathe tool
0=-3 °～10 °, relief angle α
0=2 °～12 °, cutting edge inclination λ
s=-3 °～8 °.Present embodiment is selected γ for use
0=0 °, α
0=6 °, λ
s=0 °.
Present embodiment is specially adapted to be shaped and processes the wave groove of ceramic outer surface as shown in Figure 4, because workpiece need cut the groove 8 of a plurality of circular arcs, therefore the blade of each cutter head should be trimmed to circular arc.Using method of this lathe tool and common metal cutting lathe tool are similar.Use this lathe tool to add man-hour, the convenient mounting and clamping on lathe, rapid, feel is brisk, a cutting forming of blade, energy processing ceramic tube is 2000 usually, and 5～6 new blades of a cutter head common energy cutting forming, therefore one this combination lathe tool, and the processable ceramic tube is more than 10000.This lathe tool adds man-hour in turning, and speed is fast, and it is stable to be shaped, one working day 300 in processable ceramic tube.Therefore the productivity ratio height of this lathe tool long service life, cutting workpiece.
