Precision spindle
1. This machine is mainly composed of bed and column, beam and horizontal sliding table, vertical ram type drilling power box, worktable, chip conveyor, hydraulic system, pneumatic system, cooling system, centralized lubrication system, electrical system, etc. 
Drilling and milling power head
5. This machine provides two cooling methods—internal cooling and external cooling, which provide sufficient lubrication and cooling to the tool and material during chip cutting, which better guarantees the drilling quality. The cooling box is equipped with liquid level detection and alarm components, and the standard cooling pressure is 2MPa.Chip conveyor

3. The vertical (Z-axis) movement of the power head is guided by a pair of linear roller guides arranged on the ram, with good guide precision, high vibration resistance and low friction coefficient. The ball screw drive is driven by a servo motor through a precision planetary reducer, which has a high feed force. 6. The X-axis guide rails on both sides of the machine are equipped with stainless steel protective covers, and the Y-axis guide rails are equipped with flexible protective covers at both ends. 7. This machine is also equipped with a photoelectric edge finder to facilitate the positioning of circular plate.
