FAQ

Q1: Can your company handle micro-hole machining in thin stainless steel sheets (0.5mm)? How do you ensure zero deformation?

Solution: Using ultra-fine carbide drills (minimum 0.3mm) with vacuum fixtures to suppress vibration. High-speed, low-feed technology (20,000rpm + 0.003mm/rev) allows for controllable deformation within ±0.02mm.

Q2: How do you ensure hole wall roughness and straightness during deep hole machining?

Key Technologies: Gun drilling + high-pressure internal coolant system (7MPa coolant pressure). Chip compensation every 50mm depth. Real-time tool wear monitoring and automatic offset compensation. Achieves Ra 1.6μm and straightness ≤ 0.03/100mm.

Q3: Does the processing of special materials support small-volume orders?

Service Commitment: We offer high-temperature alloy coated drills (TiAlN coating).

Customized variable parameter drilling strategies: Segmented speed/feed control.

Material Inventory Support: Customized special materials are supported.

Q4: How can we improve efficiency in group hole machining?
