◆ Product Overview
Engineered specifically for the precision drilling of disc- and ring-shaped metal components, this high-precision drilling machine delivers exceptional positioning accuracy and stable machining performance. Capable of handling materials with a hardness up to HRC35, it is tailored for standardized, repeatable operations. This makes it an ideal solution for the volume production of small-to-medium workpieces that demand stringent hole size and location tolerances.
◆ Key Features
Accurate Indexing and Positioning
Featuring a four-station rotary table powered by a high-precision servo indexing system, the machine achieves:
Repeat positioning accuracy: ≤ 0.02 mm
Indexing accuracy: within 1 arcminute
▲ This configuration guarantees uniform hole placement across all stations, significantly enhancing overall machining reliability.
Stable Drilling Accuracy
The spindle is engineered for minimal runout to maintain consistent hole quality:
Spindle radial and axial runout: ≤ 0.005 mm
Drilling depth tolerance: ≤ 0.02 mm
Hole position tolerance: ≤ 0.05 mm
▲ These tight parameters ensure the equipment reliably meets standard precision machining requirements for critical components.
Rigid Worktable Design
The worktable is tightly integrated with the indexing mechanism to maximize structural rigidity. A slanted surface design facilitates efficient chip evacuation, preventing debris accumulation that could compromise accuracy. Furthermore, key transmission components are equipped with high-precision bearings to support long-term, stable operation without accuracy degradation.
Fully Protected Structure
The electrical cabinet features a dust-proof and moisture-resistant design, while all guideways and lead screws are fully enclosed to prevent contamination. A centralized automatic lubrication system comes standard, effectively reducing component wear, extending service life, and maintaining peak operational performance.
