XK (H) 21 Series moving beam moving column CNC gantry boring and milling machines, machining centers
The overall structure of the series machine tool structure fixed to the foundation bed, column mounted on both sides of the bed, the table back and forth along the rail bed longitudinal movement (x-axis), slide board lateral movement along the beam guide rail (Y-axis) , beam vertical movement along the left column guide (w axis), square ram with headstock slide plate in a vertical movement (z-axis).
● Basic pieces of technology protection Basic machine parts from bed, table, left and right columns, beams, connecting beam, slide board, ram and other major components. Large machine is HT250-300 high-quality alloy cast iron, the VSR a hot oven aging a VSR VSR a rough one half finishing a hot oven aging a VSR a finished form, to eliminate the internal stress of the workpiece to ensure the accuracy of the long-running machine.
● Boring and milling head pillow slip 滑Ram a separate design gearbox, gear box gear automatic transmission for the two steps in order to obtain low speed high torque and high speed constant power to meet roughing and finishing requirements。
● Beam Lifting column on the left and right, respectively, to the feed motor fitted w detection grating, with synchronous control functions. Ensure dual beam infeed drive synchronization control.
● Rails form
1)x-axis: bed rail as two rectangular guide, the use of low flow pump oil bulls constant current hydrostatic guideway, it has anti-bias load, overload capacity, high stiffness characteristics of motion, slow motion smoothly without crawling , shock resistance, high operating speed.
2)Y axis slides a beam of two positive rail, a rail side rails and certain ancillary components. Long beam rails using a small flow of constant hydrostatic pump oil rail.
3)z-axis: square ram an apron square ram rails using PTFE soft belt sliding rails, with a low friction coefficient, high load capacity, smooth running, low speed without creeping characteristics。
4)w-axis: beam a column beams and columns combine rails using PTFE soft belt sliding rails, rail lubrication lubrication using fixed Cheng quantitative way to make lifting beams smooth motion, high load capacity, good wear resistance。
● Control Systems Beds can be based on different user requirements, optional Siemens, Fanuc, Fagor, Mitsubishi and other CNC system, using semi-closed loop encoder position feedback to achieve, can also be based on user requirements, using grating for full closed loop position feedback to improve machine accuracy.
● Magazine Optional Capacity 20, 24 tool disc magazine, to achieve vertical automatic tool change, or capacity 50, 60, 80 for vertical and horizontal automatic tool change (user selectable).
