Machine Introduction

 

The machine integrates powerful functions of drilling, milling, boring, expanding, reaming, rigid tapping, linear interpolation, arc interpolation, spiral interpolation, complement, three-coordinate linkage.

• Machining for various metal workpieces, such as large parts, plate parts, shell parts, molds and other precision parts.
• Widely used in industries such as shipbuilding, power generation, heavy machinery, mold manufacturing and etc.
• The international CNC numerical control system is adopted.
• It is suitable for processing oflarge parts, plate parts, disc parts, shell partsmolds and other precision parts.
• Features of high precision, high speed, high flexibility and environmental protection.
• The X-axis is supported by four rolling guide rails, and the Z-axis adopts a squareram structure constrained by four sides, with excellent machining rigidity.
• Z-axis feed is driven by double motors and double screws, with better inertia matching and dynamic response.

 

 

Machine Applications

 

It is widely used in the industries ofshipbuilding, power generation, heavymachinery,locomotive,textile machinery, printing machinery, mold manufacturing,etc.
 

 

Machine Features

 

Higher rigidity, better dynamic performance and precision

• The fixed beam structure has good rigidity, large bearing capacity of spindle, which can bear more processing intensity.
• Simple structure with light-weight moving parts makes it easier to control the machining deformation.
• Short distance between the beam and the workbench to achieve higher stability, better dynamic performance and accuracy.

Design of fixed-beam with movable worktable

• The worktable is movable (X-axis), the spindle moves along the beam (Y-axis), and the ram moves up and down (Z-axis)

 

Excellent in heavy-duty and rigid machining
 

Adopt rectangular double column gantry structure, which has enough rigidity to the load in all directions and twists, ensures high machining accuracy on the basis of high machining strength.

• The saddle is equipped with 7 sliders and ensures good anti-seismic performance
• The distance from the spindle center to the Y-axis guide surface is short, and the turning torque is small
• Large cross section of the beam and span of the guide rail
• Y axis guide adopts imported heavy-duty guide support

 

High responsiveness is achieved through the Z-axis dual servo drive

• The Z-axis dual servo manages to drive at Center of Gravity, ensuring the forces (F) on both sides are balanced, eliminating the rotation torque generated during the drive. High responsiveness and synchronization are achieved during acceleration, thus achieving stable machining accuracy.

 

High rigidity machine bed ensures stable processing

• Drive in the center of gravity for good guidance
• Screw is installed in the center of gravity position, ensures rigidity and stability
• The worktable has small overhanging and high rigidity
• The bed with four guide rail structure
• Adopts imported linear guide with high precision, high rigidity, small friction, long-term accuracy.

High strength spindle unit

• Reasonable motor installation position The heat generated during the processing is discharged upwards
• Adopts rigid coupling Faster dynamic response
• Higher strength spindle bearing With bigger diameter of the spindle bearing, the spindle structure is more stable.
• The spindle cooling Reduce the influence of machining heating on spindle accuracy.

Top-class numerical control system with high processing stability

• The Siemens and Fanuc CNC system is adopted
• With powerful functions and full-level data transmission
• Adopts a modular and open architecture design with high scalability
• Increase the flexibility and productivity of machine tool
