CNC Milling Machining - Spacer Blocks

Spacer Blocks – Provides rigid support for the custom plastic molds, ensuring positioning accuracy and stability during the forming process.

Pain Point Analysis:
Insufficient Wear Resistance: Under high working conditions, the spacer block is prone to wear, reducing its service life.

Solution:
* Material Upgrade: Use SKH51 high-speed steel (JIS standard), which has a high carbon and vanadium content that significantly enhances wear resistance and resistance to plastic deformation.
* Heat Treatment Process: Adopt vacuum hardening and tempering to stabilize hardness at HRC64, achieving uniform microstructure while balancing hardness and dimensional stability.

Verification Results:
Wear rate reduced by 50%, and service life increased by 57%.
