Methods and characteristics of grinding gear rack processing

There are many methods for grinding gear racks, each of which selects the correct processing method based on different materials and requirements for gear rack accuracy. There are mainly two methods for gear rack processing. For some high-precision and high hardness gear racks, including heat treatment of materials, processing of tooth profiles, etc., two wire cutting of tooth profiles and two heat treatment of tooth profiles are used. The rack undergoes two rounds of heat treatment and two rounds of wire cutting to alternate the tooth profile, which not only overcomes the problem of hardenability of the material after heat treatment, but also meets the hardness requirements, meets the high-precision requirements of the tooth profile, and improves the coaxiality between the tooth profile and the outer circle.

So this method has great advantages, which is that while meeting the overall hardness requirements of the tooth profile, the accuracy of the tooth profile can also meet the design requirements, greatly improving the machining quality of the grinding gear rack. Rack processing determines the hardness and accuracy of the rack, so we need to strictly control the entire process of rack processing. Different rack processing methods ensure that the processed products meet the requirements of use.

There are many characteristics of grinding gears, such as high strength and high wear resistance. The materials used have undergone quenching and tempering treatment, greatly improving the strength of the gears, adapting to high-precision linear movement, and can also change the direction of linear movement at different angles. The rack has a small module, making it easy to move and install. It is convenient to use in reciprocating situations and also easy to install.
