CNC Bending
Press brake up to [X]mm length. Accuracy: dimension ±0.15mm, angle ±0.5°.
Welding
TIG for thin stainless steel/aluminum (clean welds), MIG for thick carbon steel, spot welding for lap joints
PEM Fastener Insertion
Nuts, studs, standoffs for internal mounting points.
Deburring / Chamfering
Belt sander, vibratory finishing, chamfering machine for safe edges.
Materials We Work With for Sheet Metal Fabrication
We offer various materials for custom precision CNC turning parts. Aluminum is lightweight and easy to process. Stainless steel features great corrosion resistance, ideal for custom cnc turning shaft 304 stainless steel high precision components. Carbon steel is economical and durable. Brass ensures fine surface quality. Titanium combines high strength and light weight. POM and PEEK are reliable engineering plastics with wear and heat resistance for special applications.
