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.
2. High-rigidity bearing base, the bearing adopts high-precision screw special bearing. The extra-long mounting base surface ensures axial rigidity. The bearing is pre-tightened by a lock nut, and the lead screw is pre-tensioned. The stretching amount is determined according to the thermal deformation and elongation of the lead screw to ensure that the positioning accuracy of the lead screw does not change after the temperature rises.
Drilling and milling power head
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.
4. This machine adopts two flat chain chip conveyors on both sides of the worktable. Iron chips and coolant are collected in the chip conveyor, and the iron chips are transported to the chip conveyor, which is very convenient for chip removal; the coolant is recycled.
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.
Precision spindle
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.
