Improving the machining quality of parts: Discussion on common tool setting methods of CNC machining centers

2020-09-01 10:10

Tool setting is the most important operation content in CNC machining. Its purpose is to determine the position of the workpiece coordinate system origin (program origin) in the machine coordinate system through the tool or tool setting tool. Its accuracy will directly affect the machining accuracy of the part. For parts with different shapes and parts with different machining accuracy, the tool setting methods are also different. Based on the experience in teaching and production over the past few years, the author summed up several different tool setting methods to meet the tool setting requirements of different parts.

Nitrogen introduction [ 2020-09-02 ]
The chemical formula is N2, which is usually a colorless and odorless gas, and nitrogen is generally less dense than air. Nitrogen accounts for 78.08% (volume fraction) of the total atmosphere and is the main component of air. Under standard atmospheric pressure, when cooled to -195.8°C, it becomes a colorless liquid, and when cooled to -209.8°C, liquid nitrogen becomes a snow-like solid. Nitrogen is chemically inactive and difficult to react with other substances at room temperature, so it is often used to make preservatives. However, it can undergo chemical changes with certain substances under high temperature and high energy conditions to produce new substances useful to humans.
PTFE Introduction [ 2020-09-02 ]
Tetrafluoro is a polymer of tetrafluoroethylene. The English abbreviation is PTFE. The basic structure of polytetrafluoroethylene is.-CF2-CF2-CF2-CF2-CF2-CF2-CF2-CF2-CF2-CF2 -. Polytetrafluoroethylene is widely used in various applications that require resistance to acids, alkalis and organic solvents. It is not toxic to humans, but perfluorooctanoate (PFOA), one of the raw materials used in the production process, is considered to have carcinogenic effects.
