Requirements for stainless steel shaft machining technology: 

When machining stainless steel shaft workpieces, the cutting forces can be significant. Therefore, the machine tool's tool holder should have sufficient strength and rigidity to avoid chatter during the cutting process. Quenched and tempered 45 steel can be used for this purpose. Triangular threading tools and groove cutting tools are made of powder metallurgy materials, such as cobalt high-speed steel or aluminum-containing superhard high-speed steel, and are used for low-speed turning. The recommended chip evacuation radius is 4 to 6 millimeters with a width of 2 millimeters, ensuring smoother chip evacuation and less resistance. A thread template should be used for thread cutting, and the angle should be ground and checked continuously to achieve a 60° angle.

When machining stainless steel shafts, the geometric shape of the cutting portion of the machine tool is considered in terms of rake angle, relief angle, and chip shape. To ensure smooth chip evacuation, a chip-breaking groove with a radius of 1.5 to 3 millimeters should be ground, and a rake angle of 15° to 20° is suitable. Increasing the rake angle can reduce cutting heat generation, ensuring that the cutting temperature does not become too high.

During the initial machining of stainless steel shafts, the cutting edge of the tool should have high cutting edge strength, and a smaller relief angle is preferred. During the semi-finishing of stainless steel shaft workpieces, tool wears mainly occurs on the cutting edge and relief angle, with a wear range of 6° to 8° for the relief angle. For finishing, a larger tool inclination angle should be used, as the size and direction of the tool inclination angle determine the chip flow. To control the formation of built-up edges, it is necessary to improve the surface quality of the parts, and the optimal tool inclination angle is 3° to 5°.
