How to Choose Machining Tools for Mechanical Parts?

2022-07-08

The machining process of mechanical parts is the process of making and processing workpieces or parts. The process of directly changing the shape, size and surface quality of the blank by using machining methods to make it into a part is called the machining process. For example, the processing technology process of a common part is roughing-finishing-assembly-inspection-packaging, which is an abstract process of processing. So do you know how to choose machining tools for mechanical parts?

1. Selection of fixtures

For single-piece and small-batch production, various general-purpose fixtures and machine tool accessories should be selected first, such as chucks, flat-mouth vices for machine tools, and indexing number one; for large-scale and large-scale production, special high-efficiency fixtures should be selected to improve productivity; among various types, Small batch production can choose adjustable clamps or group clamps.

2. Selection of tools

Standard tools are usually preferred. If you choose mechanical convergence, you can choose a variety of high-efficiency special tools, compound tools and multi-blade tools. The type, standard and precision grade of the tool should match the machining requirements.

3. Selection of measuring tools

For single-piece and small-batch production, general-purpose measuring tools, such as vernier calipers, centimeters, and dial indicators, should be widely used; for large-scale and large-scale production, limit gauge blocks and high-efficiency special inspection fixtures and measuring instruments should be used. The accuracy of the measuring tool must be adapted to the machining accuracy.

The reasonable or unreasonable selection of machining skills will directly affect the machining accuracy, production efficiency and economic benefits of the workpiece. The technical equipment should be selected according to the type of local production, specific processing conditions, structural characteristics of the workpiece and technical requirements.
