What kind of tool is used to machining stainless steel material?
We all know that stainless steel is a difficult material to process, has a large work hardening tendency, high high temperature strength, and increased shear stress in the shear slip zone, so that the total cutting resistance is increased, thereby increasing tool wear. Therefore, it is very important to choose the right stainless steel processing tool.

Precision Solutions For Machining Slender Shaft
The PTJ Shop has a unique solution for the development of the process plan, the selection of equipment, and the design of the fixture when facing the slender shaft. Usually the processing of the slender shaft is done by the CNC machine. For the slender shaft with high concentricity, especially when the design of the part does not allow the U-turn machining, the PTJ Shop will select the multi-axis machining equipment to process the parts in a short time. (such as a four-axis CNC car or a five-axis machine)

Difficulties and solutions for laser cutting of thick steel plates
The laser cutting machine has no problem in cutting steel sheets below 10 mm thick. However, if a thicker steel plate is to be cut, it is often required to assist a high-power laser with an output of more than 5 kW, and the cutting quality is also significantly reduced. Due to the high cost of high-power laser devices, the laser mode of the output is also not conducive to laser cutting, so the traditional laser cutting method does not have an advantage when cutting thick plates.
