Heavy duty gantry boring and milling machining center GMC series

The overall structure of the machine tool consists of a worktable, a fixed crossbeam, and a movable gantry. The main structural components are made of high-strength cast iron and resin sand molding, which has good shock absorption and thermal stability. The whole machine has a high rigidity and high reliability structural design. Suitable for the processing of heavy and ultra heavy basic parts in industries such as metallurgy, railway, heavy machinery, shipbuilding, power generation, automotive, aerospace, printing, molds, etc., especially for CNC machining of various flat, curved, spatial curved surfaces and holes with heavy parts and long workpiece lengths. Widely used in the rough and precision machining of various complex parts such as plates, boxes, and frames in the mechanical manufacturing industry.

It can complete three-axis linkage surface machining, rigid tapping, and can add accessory milling heads according to customer processing requirements. For workpiece processing technology, it can achieve pentahedral machining with one clamping. The boring and milling head spindle is driven by an AC spindle servo motor, and the output end of the spindle servo motor is directly connected to the automatic two-stage high and low gear gearbox.

Hydraulic clamping mechanism for crossbeam and vertical slider guide rail.	The X-axis adopts a constant current static pressure guide rail, which has high load-bearing capacity, strong seismic and shock absorption capabilities, good accuracy retention, and long service life.
The crossbeam adopts a composite structure of rectangular upper and lower stepped hard rails and rolling guide rails, which offsets the overturning torque generated by the spindle box boring and milling head and the transverse sliding plate due to the offset of the center of gravity, making the Y-axis movement smooth. The lateral guide rail and inclined iron surface of the Y-axis horizontal skateboard are treated with plastic coating, which improves the accuracy and service life of the Y-axis guide rail.	The quantitative multi head pump provides hydraulic oil with a constant flow rate for the constant flow static pressure guide rail.
Static pressure oil tank temperature control, centralized lubrication method for timed and quantitative lubrication of each shaft.	The slider is equipped with a balancing device to reduce the load on the Z-axis screw and extend its lifespan.
Use an oil cooler to control the temperature rise of the main shaft and gearbox at a constant temperature.	A boring and milling spindle with configurable high torque output.
Optional all inclusive structural sliding pillow.	Standard rectangular guide rail square slider.
The dual motor clearance system controls the clamping state between the active shaft and the driven shaft through a numerical control system, ensuring optimal torque coupling between the active and driven drives, and automatically eliminating the motion clearance on the left and right sides of the X-axis.	All four axes use precision grating rulers to achieve full closed-loop position feedback, ensuring positioning and repeat positioning accuracy. The W-axis has two sets of grating rulers to ensure synchronous movement of the crossbeam
