Description

The honeycomb milling cutter

Technical field

The utility model belongs to the Tool Design technical field, particularly relates to the improvement to the honeycomb milling cutter.

Background technology

In honeycomb processing, the chip removal when cutting of existing cutter has some setbacks, and the teeth groove blockage problem often takes place, and cutter can not normally be cut, and working (machining) efficiency is low.In addition, the cutter that has cutting can occur when cutting not steady, causes honeycomb to process the product quality that influences not in place, can't satisfy processing request.

Summary of the invention

The purpose of the utility model is:

The utility model propose a kind of can smooth and easy chip removal, avoid honeycomb processing honeycomb milling cutter not in place, to improve working (machining) efficiency and yield rate.

Technical scheme of the present invention is:

A kind of honeycomb milling cutter is made up of cutter tooth on cutter hub, the cutter hub face of cylinder and the centre bore of refacing on the cutter hub, and the diameter of this milling cutter is d=10～50mm; Cutter hub width b=6～20mm, cutter tooth quantity Z=4～8, spiral groove angle α=20 °～30 °; End tooth groove angle β=30 °～55 °, anterior angle γ=10 °～15 °, relief angle δ=10 °～15 °; Secondary relief angle δ=20 °～25 °, margin width f=0.5～1.2mm has side clearance τ=1 °～2 ° on the both sides of the cutting edge width of cutter hub; Cutting edge inclination χ=6 °～20 °, profile of tooth relief angle ρ=15 °～20 °, back of tooth R=7～10mm; Tooth depth h=5～15mm, end angle of cutting edge υ=6 °～20 °.

Advantage of the present invention is:

Smooth and easy chip removal when the utility model can guarantee to cut has been avoided having improved working (machining) efficiency and yield rate greatly because of processing the product quality that influences not in place.Evidence, working (machining) efficiency have improved more than 3 times, and percent defective is reduced to below 5% by original 85%.

The specific embodiment

Explain further details in the face of the utility model down.Referring to Fig. 1～Fig. 3, the honeycomb milling cutter is made up of the cutter tooth on the cutter hub and the cutter hub face of cylinder, and the center mounting hole that has the cutter of refacing is arranged on the cutter hub; The diameter of this milling cutter is d=10～50mm, cutter hub width b=6～20mm, cutter tooth quantity Z=4～8; Spiral groove angle α=20 °～30 °, end tooth groove angle β=30 °～55 °, anterior angle γ=10 °～15 °; Relief angle δ=10 °～15 °, secondary relief angle θ=20 °～25 °, margin width f=0.5～1.2mm; Have side clearance τ=1 °～2 ° on the both sides of the cutting edge width of cutter hub, cutting edge inclination χ=6 °～20 °, profile of tooth relief angle ρ=15 °～20 °; Back of tooth R=7～10mm, tooth depth h=5～15mm, end angle of cutting edge υ=6 °～20 °.

The operation principle of the utility model is: a kind of cell-specific milling cutter, and it comprises cutter hub, cutter tooth, chip pocket, anterior angle, relief angle, helical angle, side clearance, end tooth groove angle, cutting edge inclination, the profile of tooth relief angle, tooth depth, the centre bore of refacing is formed.Cutter tooth is an important parameters of milling cutter.The number of teeth is selected for use rationally, can improve milling production efficiency and make stable cutting.Chip pocket is under the prerequisite that guarantees milling cutter intensity, to make milling cutter that enough chip spaces arranged, and cutter tooth is stopped up in the smear metal of avoiding milling cutter to be produced in the course of the work.Reasonably the helical angle parameter can make steady in working angles, the laborsaving prolongation milling cutter of milling cutter durability, enhances productivity.

Following table provides the parameter of 3 embodiment of the utility model.
