When LiCONMT company (Laupheim, germany, ann Arbor, MI) administration inspector general Mr Winfried Benz narrates this company to be its client (masses car is firstly main client) all sorts of offerred parts (black metal and nonferrous metal) when manufacturing system and treatment machine tool, pay close attention to high normal run time very much apparently. When treatment equipment is produced every year yield 100 thousand arrive when 2 million spare partses, no matter which are planted machine tool, its main shaft cannot be to be between billow take time when cutting metal. So LiCONMT company developed a kind to be called " the linear device that change a knife " (the machine tool module of LTC) , can make the time that change a knife shortens one second less than. Yes, shorter than one second. This just is not merely on the level of rigid structure have speculation, it is to build more right when high yield is produced think of quick treatment afresh. Via the engineer computation of LiCONMT company, in typical manufacturing treatment working procedure, the cutting that gives cutting tool machines cycle to be 3 seconds about. In addition, they are affirmatory already also, the cutting tool measure that treatment some spare parts uses won't exceed 20. The method that so they replaced machine tool supplier to often be used -- can change cutting tool inside 3 seconds and change a main shaft, had accomplished however from go up at all eliminate change a knife automatically -- this changes a knife than a second of time undoubtedly more surprising. Here, "Change a knife " mean use another kind of cutting tool. Other cutting tool can install the main shaft front in the one part that serves as LTC suitably. Go up at all, every have the 4 machine tools to 6 CNC main shaft to all provide power by the standard norms motor of a 15 kilowatt. Rotate speed of standard of main shaft of four-axle machine tool is top can amount to minutely 10000 turn; 6 axes machine tool can be amounted to minutely 15000 turn. The span of center of every main shaft is 160mm, cutting tool is the biggest the diameter is 125mm, the working journey of four-axle machine tool is 400 × 400 × 630 Mm; 6 axes machine tool is 600 × 600 × 800mm; Fixed position precision and repeat precision to be respectively 0.

01mm and 0.

005 Mm. Fast feed speed can amount to minutely 60m. The method of quicker treatment is a series of LTC(can offer four-axle and the configuration of 6 axes) the platoon is become all the time line, among them the cutting tool that every machine tool provides uses the process that completes limited amount only, this and the product line that form for the foundation with machining center (collateral treatment) different, the onefold machine tool among that should complete a part normally all treatment working procedure. Because this is in,the treatment status on LTC system is: Fixed in claw dish (can have spare parts fixed position 5 axes are machined thereby) the spare parts that go up can be in aspirant travel cutting machines the machine tool of series connection, and the time that change a knife is only 0.

8 seconds, this is meant can let another main shaft of cutting tool undertakes machining and do not need a dispersive cutting tool to change main shaft from the device that change a knife. This is the method that a kind of series connection machines. Mr Benz admits, if if become LTC and machining center,be being compared simply, although the treatment method speed of LTC is faster, but the price a few costlier. But he judges exposition and argumentation, "The price can not show everything " , pointing out what need a consideration more is " operational total cost " . In other words, if can produce the part with getting much rate quickly (e.g. , treatment produces aluminium alloy to turn to a section, with machining center need 143 seconds treatment is finished, and if use 3 compositive the machine tool of 6 axes LTC that be together deserves to convey with a spare parts the word of device, can shorten handling time 45 seconds) , it is very worth while to should invest so. Mr Benz complements, "Our machine tool special apply to the area with labor higher cost. " this means the premise condition that uses them is: Machine tool and equipment must have extremely tall productivity. Toyoda becomes faster through rotate speed of will tall main shaft (15000r/min) and time of cutty blame cutting (main shaft quickens / decelerate rate: 2.

3 seconds; Feed speed: 2362in.

/ Min, acceleration 1g) photograph is united in wedlock, company of United States of machine of abundant field work (Arlington Heights, the series of FH-S horizontal machining center that IL) produces can shorten whole production cycle at most allegedly 30% . System of Fanuc 30i CNC can offer port of network of industrial bus line, so PLC, PC and sensor are mixed easily net of machine tool couplet. This turning center calls the center of high yield turning of Mazak IVS 300, be " main shaft of frequency conversion vertical " abbreviation. This by Mazak company (Florence, the lathe that KY) produces has a 35 horse power 12 inches of chuck of drive of electric machinery of compositive main shaft. This machine tool offers X to 2363ipm, Z the fast feed to 1771ipm, time of knife tower dislocation 0.

2 seconds / pace. All these functions conduce to quick treatment. Maintain cutting precision to ensure the machine tool is long, when systematic temperature is elevatory, core of ball guide screw is had to the ministry drops in temperature and cool on the slide of the machine tool and main shaft functional device. Come from the milling with faster Sandvik Shanteweikekeleman (Fair Lawn, the design of milling cutter of CoroMill 210 series that NJ) offers is used at inserting mill and milling of high speed plane. Its characteristic is tall feed, axial small cut deep tangential feed has a 10 ° cut corner. Milling cutter of CoroMill 300 series had complemented to be helpful for high speed machining those who obtain tall productivity to exceed close tine milling cutter. Those who come from Mori is fast with machine for long continuously come from company of United States of dark essence machine (Irving, the NH5000 horizontal machining center of TX) has to ensure main shaft rotate speed is minutely the 14000 30 horsepower that turn are direct drive main shaft. Design of this machine tool is used at successive movement (24/7) . The knife that it has 1 second - the knife changes a knife time and gross 3.

The core of 2 seconds - core changes knife time. This machine tool has 19.

7 square inch ungual dish, can finish namely with 6 seconds only change. Automation treatment is in western industry country, automation system often is used at compensating the project with those investment and wage higher level. One facilitates with exterior or compositive automation system connective interface appears more and more important. In the meantime, the demand that generated system of the pair of effective processing that cut bits, proper ability that change a knife, tray and the most important opposite to produce environmental area to manage to the requirement of automation system. Change the standard equipment that knife device is all machining center automatically, the capacity of knife library often shows inadequacy slightly. Place has the device changing a knife of capacity of enlarge bolo library to choose in order to offer with should be being offerred at least. If the position that cuts bits can be not amassed on horizontal, ask to realize the processing cutting bits of optimization, with respect to need one machines a space to cut bits with accommodating those who fall, so that undertake automation processing to cutting bits. The particular case of the material type that the basis should process and application, when high speed is machined, should use commonly compress air or grease of cooling fluid body and a few lube undertakes cool and lubricating. All device that necessary cooling fluid and place of lubricating fluid processing need should be installed on the machine tool, so that be opposite,its are handled effectively completely. CNC Milling
