How to choose high-precision accessories suitable for CNC machine tools?

Introduction

As the core equipment for precision machining, the machining accuracy of CNC machine tools is directly related to product quality. In order to achieve high-precision operation, in addition to the excellent performance of the machine tool itself, its matching accessories are also indispensable. Below are four keys to choose suitable machine tool accessories.

1. Understand the basic configuration of CNC machine tools

Before selecting accessories, you need to have a deep understanding of the basic configuration of the CNC machine tool used, including the maximum cutting diameter, spindle speed range, tool capacity, cooling system capacity, etc. of the machine tool. These parameters directly affect the types of accessories that can be installed and their performance limitations.

2. Types and functions of accessories

Understanding the types and functions of machine tool accessories is the basis for selecting accessories. There are many types of machine tool accessories, including flexible accordion-type protective covers, steel plate stainless steel guide rail protective covers, telescopic screw protective covers, rolling curtain protective covers, protective skirt curtains, steel drag chains, engineering plastic drag chains, steel and aluminum drag chains, machine tool work lights, machine tool mattress irons, etc. Only after a full understanding can you make a suitable choice.

3. Figure out processing requirements

Processing requirements are the key factor in selecting accessories. If you need to process complex curved surfaces, you may need to choose a rotatable workbench or a five-axis linkage accessory; if you are mass-producing straight-tube parts, an automatic tool change system or a high-speed drilling accessory may be more suitable. Clarifying the size, shape, material properties and batch requirements of the processing object will help to accurately lock the required accessories.

4. Consider the accuracy index of accessories

The accuracy of accessories is directly related to the final processing accuracy. For the tool holder, focus on its radial runout and axial runout accuracy. Generally, the radial runout of high-precision heat shrink tool holders should be controlled below 3μm; the flatness, parallelism and verticality of the precision vise are the key. Only in this way can the needs of precision tool parameter adjustment be met and the processing accuracy can be guaranteed.

Conclusion

In conclusion, choosing high-precision machine tool accessories suitable for CNC machine tools is a systematic project, which requires comprehensive consideration of many factors such as machine tool characteristics, accuracy requirements and adaptability. Only by carefully selecting and matching accessories with machine tools can work efficiency be better improved.
