For engineers who use CNC lathes, encountering the problem of broken tools is a common and troublesome problem. Why do knife breakages often occur? What methods can effectively prevent knife breakage?

First of all, we need to understand the reasons why the CNC lathe tool breaks. CNC lathe tool breakage is caused by factors such as the material, structure or usage conditions of the tool. During the machining process, the higher the frequency of tool use, the greater the probability of tool breakage. Next, let’s take a look at some methods that can effectively prevent knife breakage.

1. Reduce the cutting speed appropriately

During CNC lathe processing, tool wear will become more serious as the cutting speed increases. Therefore, when using a CNC lathe, we should appropriately reduce the cutting speed, which can effectively reduce the probability of tool breakage. In addition, we can increase the flow and concentration of coolant to reduce the friction heat of the tool and improve the cutting quality.

2. Choose the right tool

Choosing the right CNC lathe tool is one of the keys to preventing tool breakage. When choosing a tool, we should consider the material and structure of the tool. For some materials with higher hardness and difficulty in machining, we can choose wear-resistant cutting tools or straight-tooth cutting tools. In addition, we can also select tool specifications based on the shape and size of the workpiece to avoid tools that are too large or too small during processing.

3. Reasonable tool shaft clamping

CNC lathe tool spindle clamping is an important factor affecting tool installation. In CNC lathe processing, the installation of the tool should be very precise to ensure that the axis of the tool and the axis of the workpiece form a certain angle. Therefore, we should choose appropriate fixtures and inspect and maintain them. In addition, the accuracy between the fixture and the tool should be maintained and the stability of the fixture should be ensured.

4. Strengthen tool maintenance

CNC lathe tools will wear out after long-term use. Therefore, in daily use, we should strengthen the maintenance of cutting tools. For example, promptly clean and lubricate the cutting edge after use, and grind and trim the cutting edge. This not only extends the life of the tool, but also effectively prevents tool breakage.

Since the occurrence of tool breakage often leads to work interruption, waste of time and cost, etc., therefore, we should strengthen the study and mastery of the skills and precautions for using CNC lathes. By selecting appropriate tools, reasonable tool shaft clamping, and strengthening tool maintenance, tool breakage can be effectively prevented and processing efficiency and quality improved.
