In order to give full play to the great economic benefits of CNC grinding machine, the following processing objects can be given priority.
1、 The parts put into operation repeatedly have better benefits.
The preparation time of the process using NC grinder accounts for a high proportion. For example, process analysis preparation, programming, adjustment and trial cutting of parts, the sum of these comprehensive working hours is often dozens to hundreds of times of the working hours of single parts, but the working contents of these CNC lathes (such as special ordinary lathe fixtures, process documents, programs, etc.) can be saved and reused, Therefore, when a part is successfully trial produced on the NC grinder and put into operation again, the production cycle is greatly reduced, the cost is also less, and better economic benefits can be obtained.
2、 It is required to focus on ensuring the processing quality and efficient production of medium and small batches of key parts.
CNC grinding machine can realize high precision, high quality and high efficiency grinding under computer control. Compared with special grinding machine, it can save many special process equipment, has strong flexible manufacturing capacity and obtains better economic benefits. Compared with ordinary grinding machines, it can eliminate many human interference factors in the long process of complex machining, has good accuracy consistency and interchangeability of machined parts, and has high machining efficiency.
3、 The processing batch of parts shall be larger than that of ordinary grinder.
When NC grinding is used to process medium and small batch parts on non NC grinding machines, due to various reasons, the pure grinding time only accounts for 10% – 30% of the actual working hours. When machining on CNC grinding machines with multi process concentration such as grinding centers, this proportion may rise to 70% – 80%, but the man hours for preparation and adjustment are often much longer, so it will become uneconomical if the part batch is too small.
4、 The processed parts shall meet the process characteristics of multi process centralized processing of NC grinder.
When machining parts, the grinding wheel cutting workpiece is exactly the same as that of the corresponding non NC grinding machine, but it can carry out some composite machining with machining accuracy requirements. For example, in terms of grinding range, ordinary grinding machine is mainly used to grind the end face of cylindrical surface, conical surface or stepped shoulder. Ordinary grinding machine can grind circular ring surface in addition to NC cylindrical grinding machine (including convex and concave surfaces), as well as the above various forms of complex combined surfaces.
5、 Balance of comprehensive processing capacity of parts.
As a single CNC grinder, it is difficult to complete all the processing contents of a part and needs to transfer and cooperate with the processing processes of other equipment, so it has the requirements of balancing the production beat and workshop production capacity. Therefore, it is necessary to give full play to the processing characteristics of CNC grinder and reasonably arrange supporting balancing processes on other processing equipment.
