1. High rigidity and high precision structural design
-
The main structure castings are made of high-quality cast iron, with stable structure and long-term quality assurance.
-
The castings are calculated and analyzed by finite element analysis method. The reasonable structural strength and reinforcement ribs are matched to provide high mechanical rigidity.
-
The three axes are supported by guides, which can endure loads and provide fast movement to ensure accurate positioning.

The main parameters
-
The frame is wide and solid, the column has a box-shaped structure, the machine saddle is widened and lengthened. The machine is designed for heavy-load capacity and has a solid structure to ensure heavy-load capacity during processing.
-
The structure of the spindle head is reinforced with ribs. The contact length ratio between the spindle head and the column is appropriate to provide stable support for the spindle.
2. High rigidity and high speed feeding system
-
The three-axis stepping motor and precision ball screw gear are directly connected to the transmission through a high-rigidity coupling to enhance rigidity and improve precision.
-
Z-axis brake motor maintains balance and sensitivity during fast movement and ensures precise processing.
-
The three axes’ linear guides, which have high rigidity, low noise and low friction, allowing for fast movement. In addition, the Ballbar system allows to pre-set parameters to achieve the best positioning accuracy.
3. Stable and reliable Automatic Tool Changer (ATC)
-
Fast, simple, reliable and long-life tool exchange device, providing smooth and reliable tool exchange action
-
Unique tool changer’s design, advanced cam drive mechanism, and the ability to select tools at any position, which can be controlled by PLC software quickly.
-
The tool changing mechanism has been tested by the supplier for millions of operations and has a high degree of reliability.
-
Quick tool changer saves non-cutting time and improves production efficiency.
-
Cam-driven tool magazine ensures high rigidity of rotation and heavy tools smooth operation.
4. Spindle drive
-
Direct drive, high efficiency and no transmission loss as with belt drive.
-
High-speed rigid tapping without drive backlash, high speed and extended tool life.
5. Mechanical tool loosening structure
-
The outer diameter of the bearing has been increased to enhance rigidity and reduce the rotation speed of the needle roller.
-
Use of precision bearings of consistent high quality.
6. Friendly human-machine operation interface
-
The control panel complies with safety regulations and is easy to operate.
-
The fault alarm signal is displayed on the screen, making it easy to eliminate the fault.
-
Embedded operation box design for easy operation.
-
Touch buttons, graphics and text logos, easy to operate.
