Basic knowledge of six machining of CNC lathe
The grinding method can be divided into cylindrical grinding, CNC lathe grinding, grinding, grinding, grinding, gear grinding, grinding, grinding tools, grinding machine grinding machine, grinding machine, grinding machine, etc.. Along with the development of numerical control technology, the development of numerical control technology plays an important role in the grinding process. Some special parts of CNC grinding machine in industry not in the ordinary grinding machine (shaft parts, such as special curve shaped parts, mold has more than three coordinate requirements etc.), so it adapts to a wide range of machining parts. In order to exert the maximum economic benefit of the NC grinding machine, the following processing objects can be given priority.
(a) the parts of the repetitive operation
Use of CNC grinding machine working hours to prepare a higher proportion of time. For example, programming, process analysis to parts the first adjustment test cut, the sum of these comprehensive work is often the single parts processing time of several times to hundreds of times, but the work content (such as special CNC lathe lathe fixture, process documents, procedures etc.) can save repeated use, so a parts in CNC grinding machine to repeat the successful trial production, the production cycle is greatly reduced, spend less, can achieve better economic benefits.
(two) to ensure that the processing quality and efficiency of the production of high efficiency, small batch of key parts
The high precision, high quality and high efficiency grinding process can be realized by CNC grinding machine under the control of computer. It can save a lot of special technology and equipment, it has a very strong flexible manufacturing capacity and good economic benefits. Compared with ordinary grinding machine, it can eliminate the interference factors of many people in the long process of complicated machining, the precision of machining parts is good, the efficiency is good, and the machining efficiency is high.
(three) the parts of the processing batch should be larger than the ordinary lathe to the NC lathe in the process of non CNC grinding machine, small batch parts, due to various reasons, pure cutting time only 10% to 30% of the actual working hours. In the grinding processing center of this kind of multi process focused on CNC grinding machine, this proportion may rise to 70% to 80%, but is prepared to adjust working hours and tend to be much longer, so will not be too small batch parts economy.
(four) the processing of parts should be consistent with the non CNC grinding machine full CNC grinding machine and multi process centralized processing process features of CNC grinding wheel cutting parts of workpiece and the corresponding is exactly the same, but it can be used in some complex processing, precision machining, such as in the range of grinding, grinding machine is mainly ordinary ordinary lathe for face grinding cylinder and circular cone or a stepped shaft shoulder of CNC lathe, CNC cylindrical grinder in addition, also can grind the torus (including convex and concave surface and surface, and only) complex combination of various forms above the surface.
(five) parts comprehensive processing capacity balance as single CNC grinding machine, it is very difficult to complete all processing a part of the process to transfer and other equipment, so the production cycle time and production ability balance requirements. So we should take into account the characteristics of CNC grinding machine, CNC lathe and reasonable arrangement of the other processing equipment on the balance of the process.
(six) some special parts processing considering some parts while the processing volume is very small, but the ordinary lathe with complex shape and high quality requirements, good interchangeability, which cannot meet the above requirements in non CNC grinding machines, CNC grinding machine can arrange to, for example, parabolic cycloid cam and special surface mirror etc..
