How to make the screw rod will not deform after heat treatment
screw rodIt is characterized by high machining accuracy and strict deformation requirements. Due to the various processing procedures, the heat treatment quality and deformation of the screw are very serious. During the production process, it was found that the workpiece was severely deformed after carburizing and quenching, and it was difficult to correct it. Large deformations also occur during the processing after heat treatment, resulting in a large number of product repairs and many workpieces being scrapped. In order to ensure the performance of the mechanism and facilitate the user's secondary processing, usually only the screw part is quenched and heat treated, while other parts can still be machined.
Its work is usually subjected to bending, torsion, fatigue and impact, as well as friction from sliding and rotating parts. screw rodThe main damage is wear and fatigue. In order to adapt to different applications on different occasions, manufacturers usually provide a variety of specifications for users to choose. The specifications of the institution are represented by a set of numbers, which can be selected directly at the time of ordering. The numbering rules for different manufacturers are different, but broadly similar. Just read the manufacturer's sample information carefully.
Duescrew rodThe friction resistance is large, so the transmission efficiency is low. For example, inCNCIn machine tools, rolling screw drive is often used instead of trapezoidal screw drive. Because the rolling surface is relatively strong and the surface finish is good. In addition, the rolling process can be used to process long strips and then cut them to any length. If high precision is required, the grinding process should be considered. However, the cost of the grinding process is much higher and may be10Times.
