The characteristics of rough machining
Roughing is intended to remove a large amount of material. For example, in the first roughing process, a material removal process is performed until the most likely surface is reached or the workpiece is completely cut. Therefore, the selected roughing tool must be of sufficient length to cut through the workpiece. The main reason for machining to maximum cutting levels is to avoid the formation of thin layers of material that can become entangled around the tool and cause failure. In machining, time is one of the main problems affecting process efficiency. The roughing operation is considered one of the time-consuming processes, especially in mold manufacturing where a large amount of material is removed
If use of CNC machining, according to your programming and installation of good tools, you can carry out high precision rough machining. And the use of CNC machining, can effectively reduce the cutting depth too deep phenomenon, reduce the risk of tool failure.
CNC rough machining is to allow the subsequent processing to proceed smoothly
CNC rough machining through the design of a good tool route can be accurate processing of steel. CNC rough machining is aimed at steel material for some simple processing, such as the basic appearance of the product or shape cutting, cutting well, will start the next step of processing. Usually after the steel is machined by CNC, there will be a lot of machining allowance, which will be used in the subsequent heat treatment and finishing
