The stand or fall of a lathe distinguishs the actor bad that depends on quality of machine tool itself. The quality that judges a machine tool is multidimensional those who spend, basically be to ask craft sex is good, rate of seriation, generalization, standardization is high, the structure is simple, weight is light, the job is reliable, productivity is advanced. We are in choose and buy equipment of a machine tool when, be about to see machine tool noumenon whether can accord with the treatment requirement of oneself above all. It is to view numerical control system next, numerical control system has a lot of sort, selecting appropriate system is the key of machine tool of numerical control of choose and buy. Final ability sees driving unit, this also is key of machine tool pilot, the treatment precision that different driving unit can achieve is different also, when choosing driving unit, the precision that wants the work that the basis processes asks to choose appropriate driving unit. Numerical control system is the control center of numerical control machine tool, element has ” of cerebra of machine tool “ say, the precision that had the machine tool that numerical control system equips to raise a spare parts to machine greatly, speed and efficiency. Must want to consider the following and main factor in selecting numerical control system: One, drive ability 2, demand of complete closed circuit and double drive demand 3, demand of 5 axle control 4, RTCP, choice leeway can be compared big. The supplier of numerical control system that involves possibly to 5 axes function with hour hand is exporting licence, after service, wait to also must consider seriously. Undertaking analytic system of open loop numerical control from respect of numerical control system is an index accuse systematic itself not to take the position to detect device, send by numerical control system a certain quantity of the instruction pulse with frequency, undertake by driving unit the machine tool locates. Below the situation that open loop system affects in exterior element, machine tool not movement or movement do not reach the designated position, but the system already arrived to appoint the position when the machine tool, right now the treatment precision of the machine tool will be reduced greatly. But because its structure is simple, react rapid, job is stabilized reliable, debug reach maintenance all very convenient, together with price is very low, because this is current,still is very big market up to now in home. System of numerical control of standard type of system of standard type numerical control includes system of numerical control of half closed circuit and system of numerical control of complete closed circuit. The positional signal of the servo electric machinery that system of numerical control of half closed circuit points to a machine tool commonly (photoelectricity coder) feedback arrives numerical control system, the system can undertake the position detects automatically compare with the error, can undertake compensating controlling to partial error, accordingly its control precision to want than system of open loop numerical control tall, but the numerical control system that compares complete closed circuit wants low. Outside the positional feedback that system of numerical control of complete closed circuit divides the servo electric machinery that includes a machine tool, the position of workbench of organic still bed detects device (use grating rule normally) positional signal feedbacks system, form total position follow-up control thereby, the system detects automatically in machining a process and compensate all position error. The treatment precision of system of numerical control of complete closed circuit is highest, but of this kind of system debug, maintenance is extremely difficult, and systematic price is very high, apply to medium, high-grade numerical control machine tool only. Because open loop commands systematic price,want than closed-loop control system low much, because this is when system of choice numerical control, the price cost proportion that should consider numerical control system to take machine tool of whole platform numerical control, reach the requirement of machine tool itself according to the configuration circumstance of the machine tool next, medium, cheap machine tool uses open loop to control a system, medium, high-grade machine tool uses closed-loop control system. Watchful problem answers to wait according to the norms dimension of the product, precision when machine tool of numerical control of choose and buy when choose numerical control machine tool to choose function of numerical control machine tool, if go after reference axis of numerical control machine tool overly to enumerate mesa of much, job and electric machinery power precision of big, treatment tall, function is all ready, so the system can be jumped over complex, dependability is low. Purchase charge and upkeep costs to be able to rise, make finished cost increases accordingly. The typical part that numerical control machine tool should machine according to need comes although machine tool of numerical control of reasonable choose and buy is had tall flexible with the characteristic with strong adaptability, but the spare parts talent with be machined particular below certain condition only achieves first-rate result. Because this is before equipment of affirmatory choose and buy, what must want the typical part of treatment certainly above all. The choice of numerical control system wants reasonable the numerical control system that should consider to be able to satisfy requirement of each performance data and dependability index in detail, want to consider facilitating operation, process designing, maintenance and government. Unite centrally as far as possible, if not be special situation, choose this unit to be familiar with relatively as far as possible, the numerical control system of the same set that is same manufacturer production, so that in the future management is mixed,maintain. Configure necessary accessory and cutting tool to divide the effect that produces numerical control machine tool to fill, enhance its process capability, must configure necessary accessory and cutting tool. Avoid by all means spent hundred thousands of yuan or 10 thousand yuan about a hundred buy a machine tool that come, cannot use because of lacking an a few yuan accessory or cutting tool normally, purchase a share along with all the others when buying lead plane fragile reach other accessory. Expert of foreign metal cutting thinks, a value the numerical control machine tool of 250 thousand dollar, the play of efficiency depends on greatly 30 dollars establish a value the function of milling cutter. This shows, provide the cutting tool with good performance for numerical control machine tool. It is to drop one of cost, crucial measure that achieve beneficial result of the biggest economic integration. Want to provide enough cutting tool for numerical control machine tool commonly, so that develop function of numerical control machine tool adequately, make what choose numerical control machine tool to be able to machine many products breed, prevent needless unused with waste. The installation that takes numerical control machine tool seriously, debug reach after checking and accept be valid waiting for labour to accuse a machine tool to take a plant, should undertake installing debugging seriously, this is very important to the following operation, maintenance, management. Numerical control machine tool is debugged in installation reach in trying moving process, technical personnel is taken an active part in, the skill that learns a supplier seriously grooms and on-the-spot guidance. The respect such as function of the geometrical precision to numerical control machine tool, fixed position precision, cutting precision, machine tool undertakes be checkinged and accept in the round. Computer software and manual of all sorts of technology data to form a complete set, use manual, maintenance manual, accessory, manual undertake checking carefully, try appropriate is custodial, after can causing day otherwise, a little add function cannot be developed and give a machine tool maintain, safeguard bring difficulty. Support of form a complete set of backing of the after service that considers numerical control machine tool to produce manufacturer in the round even finally, technology, Training Within Industry, data, software, installation is debugged, spare parts is supplied, the circumstance such as cutting tool system and machine tool accessory.
