High Precision Drilling Machine
◆ Product Overview
- This high precision drilling machine is specially developed for precision drilling of disc and ring-shaped metal components. It focuses on accurate positioning and stable machining performance, making it suitable for metal parts with hardness up to HRC35.
- Designed for standardized and repeatable drilling operations, the machine is ideal for batch production of small to medium-sized workpieces where hole size and positional accuracy are critical.
◆ Key Features
Accurate Indexing and Positioning
The machine adopts a four-station rotary table combined with a high-precision servo indexing system.
- Repeat positioning accuracy: ≤ 0.02mm
- Indexing accuracy: within 1 arc minute
This setup ensures consistent hole positioning across multiple stations, improving overall machining reliability.
Stable Drilling Accuracy
The spindle is designed to maintain low runout, ensuring consistent hole quality:
- Spindle radial and axial runout ≤ 0.005mm
- Drilling depth tolerance ≤ 0.02mm
- Hole position tolerance ≤ 0.05mm
These parameters allow the equipment to meet common precision machining standards for critical components.
Rigid Worktable Design
- The worktable is tightly integrated with the indexing mechanism to enhance rigidity. A slanted surface design helps with chip removal, reducing accumulation that could affect accuracy.
- Key transmission components are equipped with high-precision bearings, supporting long-term stable operation without significant accuracy loss.
Fully Protected Structure
- The electrical cabinet is designed with dust-proof and moisture-resistant features. Guideways and lead screws are fully enclosed to prevent contamination.
- A centralized automatic lubrication system is included as standard, reducing wear and extending service life while maintaining consistent performance.
