Frequently Asked

What are the methods of rack processing?

There are two main ways of rack processing. For some racks with relatively high precision, two wire cutting tooth profiles and two tooth profile heat treatment methods are used.

What happens to the rack after heat treatment?
First of all, the rack that has undergone heat treatment usually undergoes some deformation. The amount of deformation of heat treatment depends on the heat treatment method, material and technical requirements. The amount of deformation is about 0.02~0.10mm, and the oxide scale reaches 0.05~0.10mm ( The general modulus is 2~3mm rack).
What are the main characteristics of the rack?
The main features of the rack:

(1) Since the rack tooth profile is a straight line, each point on the tooth profile has the same pressure angle, which is equal to the inclination angle of the tooth profile. This angle is called the tooth profile angle, and the standard value is 20°.

(2) Any straight line parallel to the addendum line has the same pitch and module.

(3) The straight line where the rack is parallel to the top line and the tooth thickness is equal to the width of the tooth slot is called the index line (center line), which is the reference line for calculating the size of the rack.

What is the main scope of application of the rack?
The use of racks is very extensive. Today, Fangyuan Racks Xiaobian will introduce the main application scope of racks. Let’s take a look. Racks are suitable for fast and precise positioning mechanisms:

(1) The rack is suitable for heavy-duty, high-precision, high-rigidity, high-speed, long-stroke CNC machine tools, milling machines, drilling machines, lathes, machining centers, cutting machinery, woodworking machinery, welding machinery, stone machinery, etc.;

(2) The rack is suitable for factory automation rapid transfer mechanism, robot arm grasping mechanism, intelligent three-dimensional warehouse, etc.
