(Device diagram)Customer storiesSecond, the characteristics of the equipmentThis equipment is mainly composed of bed on both sides, rotary table, moving column, CNC horizontal power head, automatic chip conveyor and cooling device, pneumatic system, electrical system, tool magazine, etc. The bed, column, spindle box and other large parts are made of high-strength cast iron materials cast by German resin sand production line, and are treated with artificial aging heat treatment and annealing to eliminate internal stress. Using finite element analysis, the static and dynamic performance of the machine tool is effectively predicted and optimized, so that the performance of the machine tool is effectively guaranteed, and it has a high performance-price ratio. 1. Bed on both sides:The bed base is made of high-strength cast iron HT250 material cast by German resin sand production line, which has high mechanical stability and thermal stability. It adopts thin-walled multi-rib structure and compact structure, which makes the machine tool have high rigidity. After artificial aging heat treatment, annealing stress removal treatment, eliminate internal stress. Good dynamic and static rigidity. The bed is distributed on the left and right sides of the workbench, and the longitudinal (X-axis) of the mobile column moves against the bed slide seat at the level of the bed to inlet the high-bearing capacity linear rolling guide pair and precision ball screw pair, The drive is driven by a servo motor. The double-sided synchronous drive guarantees the parallel movement of the moving column, guaranteeing the perpendicularity of the Y axis to the X axis at any position. Adjustable bolts are distributed on the underside of the bed, which can easily adjust the level of the bed worktop. Heavy-duty linear guide Precision ball screw2. Move the columnThe mobile column adopts high-strength cast iron HT250 material cast by German resin sand production line, which has high mechanical stability and thermal stability.
