Abstract
This utility model relates to field of machining, especially relates to a kind of cutter.This cutter includes a cylindrical tool rest, and one end of described tool rest is connected with handle of a knife, and described tool rest is fixedly installed at least two blades one away from one end of handle of a knife.Described blade one is distributed along the axis of tool rest with different radii, and effective area of cut that described blade one is when tool rest axis rotates is amassed more than or equal to the radial section of tool rest.Such cutter can process hole on the material of higher hardness, simultaneously because have employed carbide blade, need not man-hour blade is carried out cooling process adding, has higher economy.Normal drill bit compared by such cutter, and to have deformation little, and feature that degree of stability is high, the hole of processing is compared the hole of normal drill bit processing and had the feature that axiality is high, the advantage that hole inner wall roughness is low.
Description
Technical field
This utility model relates to field of machining, especially relates to a kind of cutter.
Background technology
In field of machining, along with materials processing prescription is improved constantly, particularly in Aero-Space, mould
Producing, high ferro etc. is high to the requirement on machining accuracy of material.This has just expedited the emergence of high-speed machine tool, permissible by high-speed milling brill boring etc.
It is met the crudy that technology requires.
But, high-speed machine tool it is also proposed higher requirement to cutter, is currently mainly used carbide blade.But it is hard
Matter alloy blade, due to reasons such as its difficulty of processing are high, can only produce the blade that shape is more fixed, such as square blade, circular knife
Sheet etc..In use, first engineers and technicians are intended to the shape according to blade and manufacture and design the tool rest matched accordingly.
Which greatly limits the range of work of high-speed machine tool, also multicutter proposes higher requirement.High-speed machine tool at present
It is mainly used in High Speed Milling Operation and speed car.Certain difficulty is still had for high-precision hole machined.
Owing to the crudy of high-speed machine tool is good, it is possible to utilize high-speed machine tool to carry out bore hole, so can obtain height
The hole of quality.But also crudy to hole proposes higher requirement when utilizing high-speed machine tool to carry out bore hole.
Summary of the invention
Task of the present utility model is to provide one can use on high-speed machine tool, it is possible to effectively process hole；Also
The cutter while boring, internal surface of hole can being processed.This cutter includes a cylindrical tool rest, the one of described tool rest
End is connected with handle of a knife, and described tool rest is fixedly installed at least two blades one away from one end of handle of a knife.Described blade one is along cutter
The axis of seat is distributed with different radii, and effective area of cut that described blade one is when tool rest axis rotates is more than or equal to cutter
The radial section of seat amasss.
Further it is improved to, the side surface of described tool rest is uniformly arranged fluted around described tool rest axis.
Further it is improved to, in described groove, is fixedly installed blade two.
Further being improved to, described blade one and described blade two are carbide blade.
Such cutter can process hole on the material of higher hardness, simultaneously because have employed carbide blade,
Add and need not man-hour blade is carried out cooling process, there is higher economy.Such cutter is compared normal drill bit and is had change
Shape is little, the feature that degree of stability is high, and the hole of processing is compared normal drill bit processing hole and had the feature that axiality is high, hole inner wall roughness
Low advantage.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of a kind of cutter of utility model.
Description of reference numerals:
10-tool rest, 12-handle of a knife, 14-blade one, 16-groove, 18-blade two.
Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, to each structure involved in the detailed description of the invention of the present invention
Mutual alignment and annexation, the effect of each several part and operation principle etc. between the shape of part, structure, each several part are made further
Detailed description.
This cutter includes a cylindrical tool rest 10, and one end of this tool rest 10 is connected with handle of a knife 12, and handle of a knife 12 is in order to by cutter
Tool is fixed on lathe.On this tool rest 10, the one end away from handle of a knife 12 is provided with two cutting edges, pacifies respectively on the cutting edge of cutting edge
Equipped with blade 1.Along the radially spaced of tool rest 10, blade 1 is installed on two cutting edges in the present embodiment, as
Start to install the first blade 1 from tool rest 10 axis on one cutting edge, then the second blade one is installed on another cutting edge
14, this second blade 1 distance tool rest 10 axis certain distance, i.e. have with the first blade 1 certain overlapping, so follow
Ring, the 3rd blade 1 also has certain overlapping with the second blade 1.Overlapped between aforementioned three blades 1
Being to ensure that cutter when rotated, its effective area of cut can cover the whole end face of tool rest.Blade 1 uses hard
Matter alloy blade, is generally provided centrally with fixing hole at blade 1, by screw, blade 1 is fixedly mounted on cutting
On sword.
In order to be able to make cutter as required the inner surface in hole be reprocessed, such as bore hole or table while processing hole
Surface roughness processes.Can be by arranging groove 16 on the side surface of tool rest 10, then as desired to pacify on groove 16
Dress blade 2 18 or soft metal such as copper bar etc. realize bore hole or polishing, and groove 16 is uniformly arranged around described tool rest 10 axis
On tool rest 10 outer surface.
Certainly, cutting edge quantity can be two incessantly, can arrange multiple, it is only necessary to meets the arrangement rail of blade 1
Mark is overlapping helical form.
