Abstract
The utility model relates to a kind of milling cutters of aluminium alloy finishing, it includes cutting portion and shank, entire cutting portion is equipped with multiple chip spaces that setting is extended spirally from bottom end to shank, the face of chip space towards cutting direction of rotation is rake face, the outer peripheral surface of the rake face and cutting portion is crossed to form peripheral edge, the peripheral edge cutting edge is equipped with passivation circular arc, and cutting portion is provided with to reduce the diamond coatings for cutting frictional force and increasing cutter wearability.The milling cutter of the utility model is finished suitable for various aluminium alloy appearances, while also extending to non-ferrous metal and nonmetallic finishing.Increase nanoscale cvd diamond coating, greatly reduce frictional force when Tool in Cutting, enhance cutter wearability, greatly promote cutter life, compared with plain cutter, cutter life improves ten times or more.
Description
Technical field
The utility model relates to a kind of milling cutters of aluminium alloy finishing.
Background technique
Aluminium alloy finishing requirements are relatively high, and the very low phenomenon of the generally existing cutter life of common milling cutter, cutter is slightly
Abrasion, with regard to undesirable, the PVD mode diamond-like coating " DLC " generally used at present is only applicable to workpiece surface quality
Roughing or workpiece surface quality situation of less demanding, cutter life also just improve 50% or so.
Summary of the invention
The purpose of this utility model is to provide a kind of milling cutters suitable for aluminium alloy finishing.
To achieve the above object, the utility model uses following technical scheme:
A kind of milling cutter of aluminium alloy finishing, including cutting portion and shank, entire cutting portion be equipped with it is multiple from bottom end to
Shank extends spirally the chip space of setting, and the face of chip space towards cutting direction of rotation is rake face, the rake face and cutting
The outer peripheral surface in portion is crossed to form peripheral edge, and the peripheral edge cutting edge is equipped with passivation circular arc, and cutting portion is provided with to reduce cutting
Frictional force and the diamond coatings for increasing cutter wearability.
The utility model can be improved by following scheme:
The diamond coatings use nanoscale cvd diamond coating.
Coating layer thickness is between 0.005 millimeter to 0.008 millimeter.
The core diameter of milling cutter is 2.7 millimeters, and the radius of the passivation circular arc is 0.005 millimeter.
The top of cutting portion is provided with end tooth and the reinforcement sword to protect end tooth, reinforces the blade tip of sword and the end face of end tooth
Distance between 0.05 millimeter to 0.08 millimeter.
The milling cutter of the utility model is finished suitable for various aluminium alloy appearances, while also extending to non-ferrous metal and non-
Metal finish.Increase nanoscale cvd diamond coating, greatly reduce frictional force when Tool in Cutting, enhancing cutter is wear-resisting
Property, cutter life is greatly promoted, compared with plain cutter, cutter life improves ten times or more, and the workpiece cutting processed
Surface quality is without any exception.
Detailed description of the invention
Fig. 1 is the side structure schematic view of milling cutter in embodiment.
Fig. 2 is the structural schematic diagram of the milling cutter in embodiment under one end visual angle of milling cutter.
Specific embodiment
If attached drawing 1 is to attached shown in Fig. 2, a kind of milling cutter of aluminium alloy finishing includes cutting portion 1 and shank 2, entirely
Cutting portion 1 is equipped with multiple chip spaces 3 that setting is extended spirally from bottom end to shank 2, face of the chip space 3 towards cutting direction of rotation
For rake face, the outer peripheral surface of rake face and cutting portion 1 is crossed to form peripheral edge 4.
The core diameter (diameter D) of milling cutter is 2.7 millimeters, and 4 cutting edge of peripheral edge is equipped with passivation circular arc, the passivation circular arc
Radius is 0.005 millimeter, thus improves blade and collapses scarce requirement and flank roughness requirements, blade requires micro- at 200 times
Without scarce, Ra0.2 μm of flank roughness is collapsed under mirror, guarantee the cutting edge roundness of acquisition high quality after coating.
Cutting portion 1 is provided with to reduce the diamond coatings for cutting frictional force and increasing cutter wearability.The Buddha's warrior attendant
Stone coating uses nanoscale CVD (chemical vapour deposition technique) diamond coatings.Coating layer thickness is at 0.005 millimeter to 0.008 millimeter
Between, it is thus greatly reduced cutting frictional force, enhances the wearability of cutter, significantly promotes cutter life
The top of cutting portion 1 is provided with end tooth and the reinforcement sword to protect end tooth, reinforces the blade tip of sword and the end of end tooth
The distance d in face is between 0.05 millimeter to 0.08 millimeter.
