What does characteristic of technology of numerical control machine tool have. Numerical control machine tool is machining degree of precision, automation, production the advantage that all respects such as intensity of efficiency, labor have general accuracy machine tool to cannot be likened to, but buy numerical control machine tool especially cost of machine tool of large numerical control is very high, often make a lot of users look and cowardly pace, resemble our country especially such developing country fund is limited, consequently, most mechanical factory wants to buy and can not afford numerical control machine tool. How to acquire numerical control machine tool with less investment, it is a problem that is worth to discuss. Can not buy numerical control machine tool and undertake upgrading transforming to original machine tool, make turn numerical control into the machine tool? The answer is affirmative. Will a few years upgrade transformed experience tells us, this is well worth doing, not only economic performance is good, periodic short, and OK and managing many capital. The machine tool that is transformed is bigger, the capital with managing place is more also. It is the numerical control that some company has changes reproducing example below: Transform to axis of Z of right tool carrier. With the entrance guide screw of Li Shile ball changes former echelon guide screw (63 × drive of feed rod of take out of 10 × 3600mm) , increase drive of servo electric machinery to repair blow Z axis slideway to repair blow Z axis pressing plate, set. Electronic-controlled to the machine tool systematic design is made. Choose send system of numerical control of that division 0it to choose send that division to communicate electric machinery of digital type servo to choose homebred and joint-stock low pressure electronic-controlled machine tool of component design development dominates logistic picture. Right finally adjustment of machine tool Electromechanical. Debug precision of pair of machine tool geometry to debug precision of pair of machine tool coordinate to movement of axis of machine tool X, Z axis, with Shuang Pin laser detects each axis precision. Undertake the machine tool is assisted the function is debugged and to the machine tool 36 hours of successive air run. Function of the machine tool after transforming is stable, reliable, produce test and verify via a year many, achieved transform a requirement. The 1 million yuan 1/15 that transforms charge to be equivalent to purchasing numerical control machine tool only, for the user managing a large number of capital. This machine tool produced the spiral case in equipment of water and electricity to go out for this factory energetically, created 10 thousand yuan thousands of production value. Numerical control is changed upgrade the issue that needs an attention, what kind of machine tool suits numerical control to change upgrade reproducing? Experience proves, establish center lathe (especially large establish center lathe) , Long Menxi rises progression to accuse dig of Long Menxi, dragon door to upgrade milling machine of boring of numerical control Long Menxi, horizontal upgrades milling machine of boring of numerical control horizontal, . Numerical control upgrades transform must undertake designing reproducing again partly to machine tool machinery above all, make its achieve the requirement that numerical control changes. Adding servo electric machinery and numerical control system only simply is short of upgrades of the purpose, want to do following works commonly for this: Change with ball guide screw former echelon guide screw, raise precision, reduce attrition to repair grind blow grinding to slideway sticks model or use essence of linear scroll slideway to change main shaft directly is, raise main shaft precision to design automatic refrigeration to discharge bits system, raise degree of machine tool automation to increase the orgnaization that change a knife when necessary -- design of knife library manipulator makes automatic lubricant system. In transforming, should decide and choose numerical control system and servo. The function of numerical control system is not more better, the systematic price with much function is average more expensive also. Want to select homebred system and import system according to need. Current and homebred system and import system still have difference, pick import system commonly to equipment of large high accuracy had better. But in last few years homebred system already had great progress, already can use reliably to general lathe, milling machine. Servo electric machinery chooses to communicate servo electric machinery above all. Upgrade to reproducing numerical control contract the option of the company is very important also. Want to choose to pass the company of aptitude attestation, current reproducing industry is very non-standard still, same table machine tool transforms different company ask a price to differ very big, time difference is not as high as 2-3 times perambulate contracts of the company already outstanding achievement wants to contract company spot perambulate, those did not secure place, the company that did not stabilize technical team cannot start reproducing. A good reproducing business, want to very strong Electromechanical designs ability, want to have certain treatment engineering capability. CNC Milling
