[0002] Straightening machine is a detection and straightening device designed for shaft and rod products that have been bent and deformed after heat treatment. Automatic straightening machine is a high-tech product that integrates mechanical, electrical, hydraulic, pneumatic, and computer measurement and analysis.

It can accurately measure the radial runout of pure circular cross-section, D-shaped cross-section, and the pitch circle of gear or spline of shaft and rod workpieces. The positioning and clamping tool for straightening machine is an important part of the straightening machine, which is used for precise positioning and clamping of workpieces during straightening to ensure straightening accuracy and workpiece stability. By applying appropriate pressure or torque, the workpiece is firmly fixed on the workbench to prevent it from moving or vibrating during processing.
