Six advantages of CNC grinding machine come and have a look!

CNC grinding machine is a machine tool that uses grinding tools to grind the surface of workpieces. Most grinders use high-speed rotating grinding wheels for grinding, and a few use oilstone, abrasive belt and other abrasives and free abrasives, such as honing machine, superfinishing machine tool, abrasive belt grinder, grinder and polishing machine. CNC grinding machines also include CNC surface grinding machines, CNC centerless grinding machines, CNC Internal and external cylindrical grinding machines, CNC vertical universal High-speed Carving Machining service, CNC coordinate grinding machines, CNC forming grinding machines, etc.

The parts put into production repeatedly have better benefits

The preparation time of the process using NC grinder accounts for a high proportion. For example, process analysis preparation, programming, first article 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 part processing, but the working contents of these cnc machine milling 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.

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 artificial interference factors in the long process of complex machining, has good accuracy consistency and interchangeability of machined parts, and has high machining efficiency.

The processing batch of parts shall be larger than that of ordinary grinder

When NC grinding machine processes medium and small batch parts, due to various reasons, the pure cutting 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.

The processed parts shall conform to the process characteristics that can give full play to the multi process centralized processing of NC grinder

When machining parts, the condition of 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. In addition to ordinary grinding machine, NC cylindrical grinding machine, It can also grind toroidal surfaces (including convex and concave surfaces) and various forms of complex combined surfaces above.

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 be transferred and matched with the processing procedures of other equipment. Therefore, it has the requirements of balancing the production pace and workshop production capacity. Therefore, we should give full play to the processing characteristics of NC grinding machine, and NC grinding machine should reasonably arrange supporting balance processes on other processing equipment.

Consideration of some special parts processing

Although the processing batch of some parts is very small, ordinary lathes have complex shape, high quality and good interchangeability, which can not meet the above requirements on non NC grinding machines. They can only be arranged to be processed on NC grinding machines, such as parabola, cycloid cam and reflector of special surfaces.
