Fixed Beam CNC Drilling and Milling Machine

Machine Function And Feature Description

1) CNC gantry drilling and milling machine is a machining equipment that integrates advanced technologies such as machinery, electricity, and hydraulics. It is mainly used for processing mould, flanges, valves, structural parts ect. It is widely used in the roughing and finishing of complex parts such as various plates, boxes, frames,mould etc. in the machinery manufacturing industry. This machine tool can realize the horizontal (Y-axis) and vertical movement (Z-axis) of the vertical milling head and the table Three-axis linkage of longitudinal movement (X axis). Multi-process processing such as milling, boring, drilling, rigid tapping, reaming, and countersinking can be performed. The whole machine adopts a gantry frame structure, with high rigidity and good accuracy retention. It is the first choice for users to process.

2) Overall layout of machine

(1)The fixed beam type gantry frame structure is adopted, the bed is fixed, and the double column and the bed are connected by bolts. The worktable moves in the X axis on the bed, the headstock moves in the Z direction on the saddle, and the saddle and the headstock move in the Y direction on the beam.

(2)The main large parts of the machine tool: bed, column, beam, saddle, and headstock are all high-strength cast iron materials. These large parts are optimized by 3D computer software, with reasonable layout of ribs and complete heat treatment processes to eliminate residual stress. , To ensure that the whole machine has sufficient strength, rigidity and high stability, cutting vibration resistance .

3 )Bed-Workbench

(1) The bed is made of high-strength HT250 cast iron material, using computer three-dimensional aided optimization design, the ribs are arranged reasonably, and its rigidity and strength are improved.

(2) The X-axis guideway pair adopts imported heavy-duty linear guides, with low dynamic and static friction coefficient, high table sensitivity, low high-speed vibration, low-speed no crawling, high positioning accuracy, and excellent servo drive performance: at the same time, the load capacity is large, and the cutting vibration resistance is good. .

(3) X-axis drive-the servo motor is connected with the ball screw through the reducer, which drives the worktable to move back and forth on the bed to realize the X-axis feed movement and pre-stretch the screw to improve the Stiffness.

4 )Beam

(1) The crossbeam and the column are integrated into the gantry frame structure, using high-strength HT250 cast iron material, the ribs are arranged reasonably, and have sufficient bending and torsion rigidity.

(2) The beam guide pair adopts heavy linear guide.

(3) Y-axis drive-the servo motor is directly connected with the ball screw through the coupling, and the ball screw drives the saddle to move left and right on the beam to realize the Y-axis feed movement.

5)Headstock

(1) The headstock adopts heavy-duty roller linear guide, which has high rigidity of motion, high positioning accuracy, and good low-speed stability.

(2) Z-axis drive-the servo motor is directly connected to the ball screw through the coupling, and the ball screw drives the headstock to move up and down on the saddle to realize the Z-axis feed. The Z-axis motor has an automatic brake function. In the event of a power failure, the motor shaft is tightly held to prevent it from rotating.

(3) The spindle group adopts Taiwan Jianchun high-speed internal cooling spindle with high precision and high performance. The main shaft grasps the knife by the butterfly spring on the main shaft with the tension force acting on the pull nail of the tool handle through the four-part broach mechanism, and the loose tool adopts pneumatic method.

6)Pneumatic system

Used to loosen the tool of the spindle.

7) Machine protection

The bed rail (X axis) adopts stainless steel telescopic protective cover;

The beam guide (Y axis) adopts flexible organ protection.

8) Lubrication

(1) X, Y, Z three-axis bearings are all greased.

(2) X, Y, Z three-axis guideways are all lubricated by oil.

(3) X, Y, Z three-axis ball screw pairs are all lubricated by oil.

9) CNC system

The CNC system is standard equipped with Beijing Kaiendi control system and drive, with complete functions and easy operation; standard RS-232 communication interface, USB socket and related software.

Filtering System

This machine tool is equipped with a central water filter system, which can effectively filter impurities in the coolant. The internal water spray system can prevent iron pins from being entangled on the tool during processing, reduce tool wear, extend tool life, and improve workpiece surface finish. The tool tip high-pressure water outlet pin can well protect the surface of the workpiece, protect the high-speed rotary joint, prevent impurities from blocking the rotary joint, and improve the overall quality of the workpiece and improve work efficiency.
