XK (H) 21 series of CNC beam fixed column gantry milling machine,
machining center Introduction to machine tools The overall structure of the machine The series ofmachine tools for the bed fixed on the foundation, the column installed on both sides of thebed, the table along the bed guide before and after the vertical movement (x-axis), slidealong the beam guide to do horizontal movement (Y axis) , The beams are moved vertically(w-axis) along the left and right column guides, and the square rams are moved vertically (zaxis) with the spindle box in the slide.
 Basic parts of the process of protection Machine basic parts from the bed, table, left andright columns, beams, connecting beam, slide plate, ram and other major componentsMachine tools for the HT250-300 high-quality alloy wear-resistant cast iron, the vibration of aheat furnace aging effect of a vibration aging a rough aging of a semi-finishing a hot furnaceaging a vibration aging of a finishing to eliminate the workpiece stress , To ensure long-termoperation accuracy of the machine.

 Ram - type milling and boring head slip-down gear box Separate design, gearbox forthe two gears automatically variable speed, in order to obtain low-speed large torque andhigh-speed constant power, to meet the rough, finishing requirements.

Beam Lift up and down the column were equipped with w to the feed motor, detectionscale, with synchronous control function. To ensure that the beam feed to achieve dual drivesynchronization control.
Guide form
1) X-axis: bed guide for the two rectangular guide, the use of small flow of long-flow pump constantcurrent closed static pressure rail, it has anti-partial load, heavy load capacity, high rigiditycharacteristics, low-speed movement No crawling, strong earthquake resistance, high speed

2) Y-axis: slide a beam for the two quide rails, a side rail and a number of auxiliary rails. Cross-beamguide with a small flow of long-pumped constant current closed static pressure guide rail

3) Z-axis: square ram pillow slide slide side of the slide with PTFE flexible sliding rail, with a smalcoefficient of friction, carrying capacity, smooth operation, low speed without crawling and so on.

4) W-axis: beam-column beam and column with the quide rails with PTFE flexible sliding rails, railubrication using quantitative quantitative lubrication, so that the beam movements smooth, stronacarrying capacity, good wear resistance.

Control System Machine tools can be based on different requirements of users, matchingSiemens, Fanuc, France, Mitsubishi and other CNC systems, the use of encoder to achievesemi-closed-loop position feedback, can also be based on user requirements, the use ofgrating to achieve full closed-loop position feedback to improve the machine Accuracy.

Knife library Optional capacity of 20, 24 tool set of disc magazine, to achieve verticaautomatic tool change, or capacity of 50, 60, 80 for vertical and horizontal automatic toochange (user optional).
