Installation and processing method of cutting blade for processing precision parts

In the processing of precision parts, it can be cut off on automated equipment with complex bar feed structure or the most advanced CNC machine tools. However, improper installation and use of the cutting blade may cause downtime, tool damage, scraping of the workpiece, and even damage to the machine tool. Let the senior operator of Ami Precision teach you how to install and use the cutter.

1. Installation of cutting tool

1. When installing, the cutting blade should not be extended too long, and the center line of the cutting blade must be installed perpendicular to the center line of the workpiece.

To ensure that the two secondary declination angles are symmetrical.

2. When cutting a solid workpiece, the main cutting edge of the cutting blade must be installed at the same height as the center of the workpiece, otherwise it cannot be turned to the center.

Moreover, the precision parts are prone to chipping, and even the turning tool is broken.

3. The bottom plane of the cutting blade should be flat to ensure the turning quality.

Second, the cutting method

1. Straight-line method cuts the workpiece. The so-called straight travel method refers to cutting perpendicular to the axis of the workpiece. Cut off in this way

The efficiency is high, but there are higher requirements for the lathe and the cutting edge of the cutting knife and installation, otherwise it is easy to cause the cutter head to break.

2. Cut the workpiece by the left and right knife method. In the case of insufficient cutting rigidity, it can be cut by the left and right borrowing knife method. This way

The method refers to that the cutting blade repeatedly moves back and forth in the axial direction, and then feeds radially on both sides until the workpiece is cut.

3. The reverse cutting method cuts off the workpieces processed by precision parts. Reverse cutting method refers to the reverse of the workpiece, and the turning tool is reversely clamped.This cutting method is suitable for larger

Cutting off diameter workpieces.
