9 Errors In CNC Machining

Machining error refers to the degree of deviation between the actual geometric parameters (geometric dimension, geometric shape and mutual position) and the ideal geometric parameters. The degree of conformity between the actual geometric parameters and the ideal geometric parameters is the machining accuracy. The smaller the machining error is, the higher the degree of conformity …

Mold Heat Treatment

22 FAQs for Mold Heat Treatment

How can the hardness of H13 die steel reach 58HRC through heat treatment? It can be reached by 1050 ~ 1100 ℃ heating quenching and oil quenching. But the general hot work die steel does not be required with such high hardness because the performance will be very poor under high hardness. Generally, the hardness in the range of HRC46-50 …

Servo Motor vs Stepper Motor

Servo Motor vs Stepper Motor (Working Principle and Performance Difference)

Stepper Motor Working principle of stepping motor Stepper motor, as a special motor for control, is the actuator of converting electric pulse into angular displacement. When the stepping driver receives a pulse signal, it drives the stepping motor to rotate at a fixed angle in the set direction (called “step angle”). It rotates step by …
