Production efficiency is improved, cost is reduced, ensures product quality.
(1) multi-cutter-position cutter spindle processes strong applicability.Milling machine arbor one end is strained and fixed by pull rod on lathe, the other end
Pass through top fixation on lathe.The length of axial dottle pin can be adjusted at any time to adapt to various sizes of processing needs.Processing
Specification is more various, and previous key groove clamp can only be processed the wide size of single key.This keyseat clamp can clamp width
Spend the key of size 5mm -16mm specifications.
(2) Simulation Based On Multi-step time processing, production efficiency are high.Be fixedly mounted respectively on milling machine arbor different location long key milling cutter and
Angle cutting tool, in addition milling cutter of woodruff key passes through handle of a knife and milling machine arbor Mohs coordinates, the top fixation of axial direction.To realize multitool one
Clamping is played, Simulation Based On Multi-step time processing improves production efficiency.
(3) it eliminates Simulation Based On Multi-step and accumulates mismachining tolerance, Product Precision improves.The long key and woodruff key and axis tooth of usual jackshaft
There is position degree requirement, there are accumulated errors for separate machined.Now processing accumulated error can control within 0.01mm together, product
Qualification rate 99.9%.
