Suzhou Doushan machine tool is a comprehensive equipment, with milling machine, boring machine, drilling machine and other functions, it has a high production efficiency, the use of special process equipment such as special fixtures, replacement of workpieces, just call the NC device stored in the processing program, fixture and tool data, greatly shortening the production cycle, then Suzhou Doushan machine tool milling process What are the characteristics?

1、刀具进出条件：铣刀每次进入切削时，切削刃都会受到冲击载荷的影响，这取决于切屑截面、工件材料和切屑类型，对于铣削加工来说，切削刃与工件材料的初始接触类型以及接触是否合适非常重要， 此外，刀具的定位对于切削刃的进出也很重要。

2、加工中心铣削方向的选择：铣削时，工件可以沿或相对于刀具旋转方向进给，这会影响切削的起始和完成特性，无论对机床、夹具和工件的要求如何。However, if the tool is pushed into the workpiece, the feed amount will increase irregularly, resulting in excessive cutting thickness and tool collapse. In these applications, reverse milling should be selected. When the machining allowance changes greatly, it is more advantageous to choose reverse milling.

In most cases, machining center milling has the characteristics of ultra-precision, small batch, complex process, etc. Therefore, when selecting cutting oil, special cutting oil for machining center should be selected. Special cutting oil for machining center has excellent extreme pressure and wear resistance, which can effectively improve machining accuracy. It has good versatility and is suitable for various complex machining center processes. Compared with non-special rapeseed oil, it can greatly prolong the service life of tool equipment and avoid rust, yellowing and other problems. Reduce the comprehensive production cost of enterprises.降低企业综合生产成本。

4、铣刀直径和位置：铣刀直径的选择通常根据工件的宽度和机床的有效功率而定。Especially in face milling, the width of the workpiece will directly determine the diameter of the milling cutter. Under normal circumstances, the diameter of the milling cutter should be larger than the width of the workpiece, because this helps to ensure good chip formation and proper cutting edge loading. Ideally, the position of the tool should always be slightly off-center. Because the cut formed by each blade is very small at this time, and the entry and exit of the blade facilitates the formation of chips and prevents impact loads. However, if the tool is centered, the average radial force will change in direction as the cutting edge enters or leaves the cutting edge, the spindle will vibrate, and the insert may break, resulting in poor surface quality. The position of the milling cutter relative to the workpiece, the tool path, and the contact with the tool teeth are very important factors for successful completion of the process.
