CNC CNC lathe processing repeatability of production parts: the use of CNC grinder process preparation time occupies a higher proportion. For example Process analysis and preparation, programming, first part adjustment and trial cutting, etc., the sum of these comprehensive working hours is often tens to hundreds of times of the working hours of a single part, but these CNC lathe work contents can be saved and reused, so a part is successfully trial produced on the CNC grinder, and then put into production repeatedly, the production cycle is greatly reduced, the cost is also less, and better results can be achieved The economic benefit of the project is very good.
It is required that the CNC grinding machine can achieve high precision, high quality and high efficiency grinding under the control of computer. Compared with special grinding machine, it can save a lot of special process equipment, has strong flexible manufacturing capacity and obtains better economic benefits. Compared with ordinary grinding machine, it can eliminate many artificial interference factors in the long process of complex processing, and has good precision consistency and interchangeability of processing parts, and high processing efficiency.
The parts processed by CNC lathe should be able to give full play to the process characteristics of multi process centralized processing of CNC grinder. When CNC grinder processes parts, the situation of grinding workpiece with grinding wheel is exactly the same as that of corresponding non CNC grinder, but it can carry out some complex processing with machining accuracy requirements. For example, in the grinding range, ordinary grinder is mainly used for grinding cylindrical and circular CNC lathe In addition, it can also grind torus and complex combination surface of various forms.
The processing batch of the parts should be larger than that of the ordinary lathe to the batch CNC lathe. When the medium and small batch parts are processed by the non CNC grinder, due to various reasons, the pure cutting time only accounts for 10% – 30% of the actual working hours. When machining on the CNC grinding machine with multiple working procedures, such as grinding center, the proportion may rise to 70% – 80%, but the working hours for preparing to adjust are often much longer, so it will become uneconomic if the batch size of parts is too small.
CNC CNC lathe processing of some special parts to consider, there are some parts, although the processing batch is very small, ordinary lathe, but the shape is complex, high quality, good interchangeability, which can not meet the above requirements on non CNC grinder, can only be arranged to CNC grinder processing, such as parabola, cycloid cam and special surface mirror, etc.
