Precision Parts Touch Control Plate

Current Situation:
The touch control plate, as a core medical precision parts of touch operation panels in medical devices, must meet the following requirements:
High-hardness tungsten carbide material;
Ultra-high precision (dimensional tolerance ±0.005mm);
Super smooth surface (roughness Ra ≤ 0.2μm).

Core Challenges:
Processing Difficulty: High-hardness materials lead to rapid tool wear and low processing efficiency.
High Precision Risks: Traditional processing methods may introduce stress deformation or subsurface damage.
Surface Smoothness: Ordinary processes struggle to achieve ultra-smooth surfaces.

Optimized Solutions:
Rough Machining: Use medium-speed wire cutting (precision ±0.02mm) for shaping.
Finish Machining: Utilize slow-speed wire cutting (precision ±0.003mm) for final tungsten carbide parts.
Local Surface Treatment: Manual polishing to achieve a surface roughness of Ra ≤ 0.2μm.

Technical Advantages:
Completely avoids mechanical stress associated with traditional cutting processes.
Improved surface integrity, with a reduction of micro-cracks by 80%.
Enhanced dimensional stability, with tolerance control within ±0.003mm.

Actual Benefits:
The precision parts for medical devices help our customer reduce overall production costs by 12%..
