Meeting admiral is exhibited to be rolled out first in CIMT2007 " Combination 90 " machine tool, it is machine of new generation mill coming back, can machine the EPS screw with an exterior extremely high quality directly, do not need any follow-up nap working procedure. What is mill coming back? From treatment tool and respect of mechanical movement principle are told, mill coming back is a kind of of milling craft special form. It is with craft of outward turning mill exemple, treatment tool is one inside file tine rotates bit body, namely milling cutter is located in bit body inside. When treatment centrifugal bit body rotates around workpiece with tall revolution, workpiece circles axes roll with slower rate. Bit body decided the rake of whorl for axial corner with X line, the trend of the tangent plane that assures milling cutter at the same time and whorl is consistent. The fluctuation radial feed of axis of X of bit body edge decided the deepness of whorl. Machine of mill coming back can machine a different rake, the left, right two-way whorl of different deepness. According to diverse treatment demand, bit body and add workpiece to be able to be retrorse roll along same way or each other. Craft of this kind of treatment has two big distinct advantages: The first, revolution of the workpiece when treatment is very low, have 20r/min only, avoided to machine the blame counterbalance negative effect to workpiece itself so, improved completely machining longer when workpiece, the Yi She that often appears bends a phenomenon easily. The 2nd, the mechanical movement characteristic of this kind of craft makes what be dropped by even mill drossy the quantity of heat of the generation when taking away treatment, avoided the effect of this kind of heat energy to workpiece completely. Differ with machine tool of common thread milling, machine tool of mill coming back is processing the form of drossy and similar comma that the mill in the process drops, this kind flexible the advantage that machines a characteristic depends on, managing mechanical kinetic energy, rose to cut mill speed and feed rate, improved manufacturing efficiency greatly. Perfect surface is bright and clean at the same time degree can rival with burnish craft photograph. The cutting tool material of machine of mill coming back has pottery and porcelain and hard alloy two kinds, the high content of the carbide in these two kinds of material, nitride raised the durability of the tool greatly, prolonged the service life of the tool. Additional, what drop as a result of the mill in machining a process is drossy the quantity of heat of the generation when taking away major treatment (80%~90% ) , workpiece itself does not suffer his to affect, so most circumstance falls to be able to undertake working machining to workpiece, saved a good deal of expenditure that is used at cooling lubricant and clean job so. Laisiteruicike the specific requirement according to the client, offer the opportunity of mill coming back of all sorts of norms and configuration, from the mainest 5 axes machine tool (A axis, C axis, X axis, Z axis, numerical control operates tailstock) , to contain a back to maintain stand, built-in bracket, pack the discharge system machine tool that can deserve to have 15 axes at most automatically. Allow to design through holding the Gao Shui that accuses system and gearing, laisiteruicike offers a delegate most the machine tool of mill coming back of the advanced technique. The pinpoint accuracy that manufactures technology and batch productivity decided manufacturing economic benefits. The manufacturing efficiency of machine of mill coming back compares Laisiteruici tower above of general fore-and-aft turning machine is severalfold, because general fore-and-aft turning aircraft can undertake only way is machined only, the production of parts of very inaccessible high level asks. The technology of mill coming back of economy, actual effect, unifinication by more and more apply widely, in order to replace car, mill, grind wait for a tradition to machine craft. The hi-tech function index of machine of mill coming back reflects the high spirit of the tall tigidity in the machine tool and process to be spent definitely, in addition still install stock to measure system and the torque driven type that deserve to have CBN tool to come back directly milling head. Machine of mill coming back can complete the good treatment to main shaft directly, saved a tradition to machine the burnish working procedure in the method. The another advantage that nots allow to ignore is mill coming back when, because workpiece rotate speed is very slow, operation personnel can detect at any time in machining a process already machined the cochlea shank diameter that go out. Laisiteruici produces technical limited company to basically be in charge of machine of complete set mill coming back (use at production to have whorl and the component that are like whorl structure) develop with the production of the machine that play slot and technology. In addition, still provide the tool of milling He Xuanxi that develops development completely by oneself. In last few years Laisiteruici produces technical limited company to be especially inside development / processing technique respect acquired outward turning mill a series of progress. Machine craft to be able to machine a ball guide screw accurately to reach its through this the main shaft of nut, pump, prejudicial screw, whorl shape that changes screw, EPS screw, gear screw, bone screw and other and special application to the domain product.
