Economic Boring and Milling Machining Center CNC Machine

1. Description anduse of equipmentThis equipment is mainly used for the efficient processing of boring and milling of double-sided holes of booms, slender profiles or structural parts such as one arm, two arm, three section arm and basic arm. The two spindles can be machined on both sides at the same time or independently. The machine tool processing process is digitally controlled, and the operation is very convenient. It can realize automation, high precision, multi-variety, mass production.YZZX7010 boomdouble-sided boring machineis anew type of efficient and intelligent processing equipment independently developed by our company. The equipment has good system rigidity and high precision, high life, high reliability, high positioning accuracy, stable operation and low energy consumption, which can meet the needs of efficient production of enterprises. Widely used in engineering machinery, steel structure, bridge, pressure vessel, chemical environmental protection, shipbuilding and other industries.Second, the characteristics of the equipmentThis equipment is a workbench mobile structure, mainly composed of bed base, mobile workbench, left and right moving column, CNC horizontal boringand milling power head, cooling device, hydraulic system, centralized lubrication system, chip removal device, electrical system, CNC system, disc tool magazine, etc. The bed base, workbench, column, headstock and other large parts aremade ofhigh-strength cast ironHT300 material cast by German resinsandproduction line, whichis 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 base:The bed base adoptsspecial rib plate arrangement, and the structure is compact, so that the machine tool has high rigidity. After artificial aging heat treatment, annealing stress removal treatment, eliminate internal stress, dynamic and static rigidity is good. Two linear roller guide pairs with ultra-high bearing capacity and precision heavy-duty ball screw pairs are arranged on the plane of the bed, and the drive is driven by servo motors through precision planetary reducers. It is used to do X-direction motion feed in the table. The lead screw is pre-stretched during installation, eliminating the gap and high transmission accuracy. Adjustable bolts are distributed on the underside of the bed base to easily adjust the level of the bed worktop. Heavy-duty linear guide rails Precision heavy-duty ball screws 2.MobileWorkbench:The table guide rail pair adoptsheavy-dutylinear rollerguide pair, which has small changes in dynamic and static friction, high sensitivity of the table, small high-speed vibration, no crawling at low speed, high positioning accuracy and excellent servo drive performance; At the same time, the bearing capacity is large, the cutting vibration resistance is good, which can improve the characteristics of the machine tool, improve the accuracy and precision stability of the machine tool, and extend the service life of the machine tool.  Several T-grooves are machined on the work surface, which can beused to install special fixtures ordirectly clamp the workpiece. The workbench is equipped with workpiece positioning clamping tooling, which is composed of longitudinal positioning pressing device, lateral medium pressing device, auxiliary support, etc. As shown in the image above:When working, the workpiece falls on the tooling, and the longitudinal positioning is backed by the mountain, the lateral centering device pushes the workpiece laterally, and the lateral positioning is close to the mountain, to realize the positioning of the workpiece, and the hydraulic clamping cylinder presses the workpiece to realize the automatic clamping of the workpiece. When machining a long workpiece, an auxiliary support device can be used to carry out the lower auxiliary support of the workpiece to avoid the lower winding deformation of the workpiece.3. Move the column left and rightThe left and right moving column adopts thick-walled multi-ribbed structure, compact structure, so that the machine tool has high rigidity, andis annealed to stress relieve. The mobile column is installed on the slide table, and the imported high bearing capacity linear rolling guide pair and precision ball screw pair are arranged horizontally on the slide, and the drive adopts servo motor drive to make the moving column do lateral feed movement (Y axis), and the horizontal power head is installed in the middle of the front of the column with high rigidity. On the front side of the column, two linear rolling guide pairs with ultra-high bearing capacity are installed. And the precision ball screw pair and AC servo motor are installed above, so that the spindlepower box moves vertically up an
