Application:
The CNC gantry drilling and milling machine is mainly used for the drilling, chamfering, tapping, and milling of plate/structural parts with the thickness of flanges, discs, rings, plates and other workpieces within the effective range. Drilling through holes and blind holes can be realized on single material parts and composite materials. The processing process is digitally controlled and the operation is very convenient. It can realize automation, high precision, multiple varieties and mass production.
Equipment structure:
The equipment is integrally cast, mainly composed of worktable,
fixed beam gantry, movable sliding saddle, drilling and milling
power head, automatic lubrication device, protective device,
circulating cooling device, digital control system, electrical
system, etc. Rolling hard rail pair support and guidance, precision
lead screw pair drive, the machine tool has high positioning
accuracy and repeat positioning accuracy.
T-slot workbench:
The workbench is made of gray iron (HT250), which is finished by
secondary tempering and vibration aging treatment, with good
rigidity and no deformation.
Fixed beam type gantry:
The gantry is made of gray iron (HT250). The front side of the
gantry is equipped with two ultra-high bearing capacity rolling
linear guide pairs, a set of precision ball screws and a servo
motor to make the power head slide plate move in the Y axis
direction , drilling power head is installed on the power head
slide plate. The gantry movement is realized by the rotation of the
ball screw driven by the servo motor through the precision
coupling.
