Straight Teeth Milled Racks DIN8

DIN8 straight - tooth milled racks belong to the medium - precision level, which is a fine - milling level. Its tooth profile error is relatively small, and the pitch error is also controlled within a certain range, which can ensure relatively smooth transmission in most applications.

42CrMo is often used as the material. If it needs to work under heavy - load conditions, it can be heat - treated. After quenching and tempering treatment, the surface hardness of the tooth can reach HRC20 - 25.

• Relatively High Precision: Straight Teeth Milled Racks DIN 8 are manufactured with strict tolerances, ensuring accurate tooth profile and tooth pitch. 
• High Transmission Efficiency: The straight-tooth design enables direct power transmission when the gear meshes with the rack, with an efficiency of over 95%, which can effectively save energy.
• Good Wear Resistance: Its surface can undergo treatments such as grinding and quenching, with a hardness of up to HRC 45-50. The surface is wear-resistant and smooth, not easy to break during operation, and can withstand long-term friction and load.
• Strong Compatibility: The rack adopts a straight-tooth design, which is suitable for series installation. It can be combined with various types of gears and reducers, and can provide targeted transmission effects in different fields and working conditions.
• Easy Installation: Some Straight Teeth Milled Racks DIN 8 are equipped with pre-drilled holes and other mounting structures on the surface, which can be quickly and firmly installed on equipment. This saves installation time and effort and simplifies the assembly process.
• Good Cost-Effectiveness: Compared with racks of higher precision grades, Straight Teeth Milled Racks DIN 8 have a relatively simpler manufacturing process and lower cost, featuring favorable cost-performance. They are suitable for equipment that does not require extremely high precision.

It is suitable for occasions with higher precision requirements, but not as strict as DIN6. It is commonly used in automated production lines, general - purpose machine tools, gear reducers and other equipment, which can realize the conversion between linear motion and rotational motion, and transmit power and motion.

Main Production Equipment

The main equipment consisting of rack milling machines and grinding machines are imported from Germany.

 

The rack grinding machine
The ZSM compact moves the machine table in the X direc-tion (Table machine). For helical racks, the grinding slide to +/- 30 degrees by manually pivoted.The basic machine includes a range of equipment, which allows the machine to use in high availability for the accurate production.
