Piston rods can be used in hydraulic and pneumatic systems, and their processing requirements are relatively high. Therefore, the quality of hydraulic cylinders is mostly affected by the quality of the piston rods.

Machining Methods and Guidelines for Gears

Gear grinding: IT6~IT4 → IT3, Ra: 0.8~0.2 μ M principle: forming method and generating method.

(1) Gear grinding by forming method IT6~IT5, Ra: 0.8~0.4 μ m. Grinding with a shaped grinding wheel

We mainly introduce the main features of various racks

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