Product Description

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.

1.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.

2.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.

3.Movable sliding saddle:

The sliding saddle is a precision cast iron structure. The sliding saddle is equipped with two ultra-high load-bearing CNC hard-track sliding tables, a set of precision ball screw pairs and a high-precision planetary reducer connected to the servo motor to drive the drilling power The head moves in the Z-axis direction, which can realize the fast forward, work forward, fast reverse, stop and other actions of the power head. It has the functions of automatic chip breaking, chip removal and pause.

4、Drilling power head:

The drilling power head adopts a dedicated servo spindle motor, and the geared synchronous belt decelerates to increase the torque to drive the precision spindle. The spindle adopts the first three rear two five-row Japanese angular contact bearings to achieve stepless speed change. The spindle is equipped with a pneumatic tool change system to enable tool replacement Fast and convenient, the feed is driven by a servo motor and a ball screw. The X and Y axes can be linked, using semi-closed loop control, which can realize linear and circular interpolation functions. The spindle end is a BT40 taper hole, equipped with Italian Rotofors high-speed rotary joint, and can use high-speed U-drilling center to discharge water.
