On May 12, the 7th China International Defense Electronics Exhibition opened as scheduled, and hardened computers became a dazzling star in this exhibition. Words such as fully hardened computer, hand...
Labeling machines are an indispensable part of modern packaging. At present, the market for labeling machines in China has gradually increased, and the technical level has also been greatly improved. ...
Most 5-axis machine tools have a 3+2 structure, that is, the three linear motion axes of x, y, and z plus two rotation axes of the three rotation axes of a, b, and c that rotate around the x, y, and z...
In recent years, with the rapid development of the economy, the machine tool industry has also developed by leaps and bounds: it is reflected in the wide application of new technologies and the obviou...
Mechanical equipment maintenance management is a systematic project with comprehensive technology, high requirements, interconnection and coordination. In the entire project, the control of equipment ...
“Four must have” A shaft must have a sleeve, a wheel must have a cover where there is a table, there must be a column, where there is a hole, there must be a cover “Four No Repairs&#...
1. Working principle The ball screw nut pair is a transmission pair that puts balls between the screw and the nut, and the screw and the nut become a driving pair of rolling friction. Both the screw 1...
The machine tool coordinate system is the inherent coordinate system of the machine tool, and the origin of the machine tool coordinate system is called the machine origin or the machine zero point. A...

1. Fixing the bushing When the bushing and copper sleeve gear shaft are moving, do not change the direction due to vibration. At the moment, you need a copper sleeve, and the bearing sleeve helps to s...
Cnc Machining, both manual and automatic programming, involves process analysis of pre-programmed machined parts, process planning, selection of appropriate tools, and determination of cutting volumes...
Since it is an aluminum alloy die cast, it is not possible to cut the aluminum directly, but the aluminum must be melted into a fluid to facilitate subsequent molding on the die Once these metals beco...
Preamble: Titanium alloy has a small elastic modulus of elasticity. For example, the modulus of elasticity of TC4 is E = 110 GPa, which is about half the modulus of elasticity of steel. Therefore, the...
Aluminum alloy profiles are lighter and softer than steel, and stamping parts are easy to break. In addition, some aluminum alloy products require subsequent surface treatments such as wire drawing an...
