The highest machining accuracy that can be achieved by turning, milling, planing, grinding, drilling and boring

Machining precision is mainly used to characterize the fineness of products, such as cnc turning parts and cnc milling parts, and is a term used to evaluate the geometric parameters of machined surfaces. Machining accuracy is measured by tolerance grade. The smaller the grade value, the higher th... Read More

Common Sense of Selection and Use of Fixtures for CNC Machine Tools

At present, mechanical processing can be divided into two categories according to the production batch: one is single piece, multiple varieties and small batch (referred to as small batch production); The other is small variety and large batch production. The former accounts for 70~80% of the tot... Read More

What is the maximum machining accuracy of the machine tool?

Turning, milling, planing, grinding, drilling, boring, the highest accuracy of these machine tools and the tolerance levels that various processing methods can achieve are all here. TurningThe cutting process in which the workpiece rotates and the turning tool moves in a straight line or curve i... Read More

Cutting skills, NC machining skills

When we operate CNC machine tools to process CNC Machining parts, we often use the following tool walking skills: 1. The speed of white steel knife shall not be too fast.2. The copper workers should use less white steel knives for rough cutting and more flying knives or alloy knives.3. If the wor... Read More

Positioning and clamping of machining

This is the summary of the people in the industry when summarizing the fixture design, but it is far from simple. In the process of contacting various schemes, we found that there are always some positioning and clamping problems in the preliminary design. In this way, any innovative scheme will ... Read More

What do 4.4 and 8.8 on threaded bolts mean?

The performance grade of bolts used for steel structure connection is 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9 and so on. Bolts of grade 8.8 and above are made of low carbon alloy steel or medium carbon steel and heat-treated (quenched, tempered), which are generally called high strength bol... Read More

Hole processing knowledge, very comprehensive, a must-read for robots

Compared with external surface processing, the conditions of hole processing are much worse, and it is more difficult to process holes than to process external circles. This is because: 1) The size of the tool used for hole machining is limited by the size of the hole to be machined, and the rigi... Read More
