DetailsParameterVideo

Fine-milled racks are divided into straight teeth and helical teeth. The overall quenching and tempering heat treatment is completed. Guaranteed high tooth surface consistency. You can choose straight or helical teeth, module 2-5, length 500-1000mm.

Rack Features:


1 The end design that can be extended can be connected/interchanged at will, and the stroke can be extended infinitely.


2 The accumulative error of precision milling level is 0.080mm≥1000.


3 With straight tooth/helical tooth profile, it is suitable for various usage conditions.


4 There are heat-treated/unheated types, and the same modulus can have multiple strengths.


5 Grinding the back and sides after tempering




Quenching and tempering treatment is a double heat treatment of quenching and high temperature tempering, and its purpose is to make the workpiece have good comprehensive mechanical properties.


"High temperature tempering" is generally used to perform high temperature tempering on the quenched parts, which is called quenching and tempering in heat treatment. Quenching and tempering can make the steel obtain good comprehensive mechanical properties (hardness; toughness). Generally, the parts that are subjected to alternating loads are mostly tempered and tempered. quality treatment.


Quenching and tempering usually refers to the heat treatment process of quenching and high temperature tempering to obtain tempered sorbite. Quenching and tempering has one more high-temperature tempering process than quenching. Quenching and tempering includes quenching.


Modulating the rack makes the steel parts obtain a good combination of strength and toughness, which not only has high strength, but also has excellent toughness, plasticity, and cutting performance.
