The screw: how to prevent screw deformation after heat treatment
screw rodIt is characterized by high machining accuracy and strict deformation requirements. Due to the large number of machining procedures, the quality and deformation of heat treatment are very important. In production, it is found that the workpiece will be severely deformed after carburizing and quenching, and it is difficult to correct it. Large deformation also occurs during the processing after heat treatment, resulting in a large number of product repairs and many workpieces scrapped. In order to ensure the performance of its mechanism and facilitate users to perform secondary processing, usually only threaded parts are quenched and heat treated, while other parts can still be machined.
It is often subjected to bending, torsion, fatigue, impact and friction on sliding and rotating parts. The main damage of the screw 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 directly selected when ordering. Different manufacturers have different numbering rules, but they are roughly similar. Just read the manufacturer's sample information carefully.
Due to the high frictional resistance of the screw, 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.
