Heavy cutting CNC vertical lathe is a high-precision and high-efficiency machine tool that is widely used in various industrial fields. However, the workpieces used in such machines must meet certain requirements to ensure the production of high-quality parts. This article will introduce to you what requirements the workpieces used for heavy cutting CNC vertical lathes should meet.
1. Material requirements
The workpiece materials used in heavy cutting CNC vertical lathes should meet the following requirements:
1. It has high strength, high stiffness and high wear resistance;
2. It has good cutting performance, such as easy cutting and processing, not easy to be thermally deformed, etc.;
3. It has good heat treatment plasticity and forming processing performance;
4. Has low internal stress and deformation rate.
2. Size requirements
Heavy cutting CNC vertical lathes have higher requirements on workpiece size. The specific requirements are as follows:
1. The size of the workpiece should comply with the processing range and should not exceed the upper limit of the machine tool's processing capacity;
2. The size of the workpiece should meet the accuracy requirements, and the dimensional error should be within the tolerance range;
3. The size of the workpiece should meet the clamping requirements to facilitate machine tool clamping and processing.
3. Surface quality requirements
The surface quality of workpieces processed by heavy cutting CNC vertical lathes should meet the following requirements:
1. The surface roughness should meet the design requirements, and the roughness is usually required to be between Ra0.8-3.2;
2. The surface should be free of cracks, burrs, scratches and other defects;
3. The surface should be free of a large amount of residue, rust, scale and other foreign matter.
4. Design requirements
Workpieces used in heavy cutting CNC vertical lathes should meet the following design requirements:
1. The workpiece should have good mechanical properties, such as strength, stiffness, fatigue resistance, etc.;
2. The structure of the workpiece should be reasonable and easy to manufacture and process;
3. The appearance of the workpiece should be beautiful, clean and free of burrs and other defects.
The workpieces used in heavy cutting CNC vertical lathes need to meet various requirements such as material, size, surface quality, and design. These requirements are all to ensure that machine tools can stably and accurately process high-quality parts and provide stable guarantee for industrial production.
