TURNING AND MILLING

Complete Turning

Maximum bar diameter 76mm
Maximum turning spindle torque 400Nm
Maximum turning diameter of 500mm achieved through a long-travel moving column

5-Axis Milling

Y-axis travel: ±105 mm, meeting the machining requirements of the workpiece
Milling spindle speed: 12,000 rpm; maximum torque: 88 Nm
Swivel axis rotation range: ±120°, equipped with a full closed-loop feedback system
Capable of high-performance milling, fixed-axis inclined surface machining, and 5-axis simultaneous machining
Both the left and right spindles can perform high-precision C-axis operations,and by combining with the milling spindle,they can perform a variety of machining functions such as turning, milling, and synchronous cutting in one clamping.

FEATURES

Basic Structure

Intuitive and stable high-rigidity structure maintains consistent performance across diverse machining conditions.

Stable Design: Utilizing FEM (Finite Element Method) analysis achieves outstanding machine tool stability. All guideways are sealed with protective sheet metal to prevent high-temperature chips and coolant from contacting the guideways, thereby maintaining excellent precision over the long term.
Feed Axes: Extended axis travel and increased rapid traverse speeds enable high productivity in component machining. Orthogonal movement of the X, Y, and Z axes achieves high precision and repeatability.
Roller Linear Guideways: High-quality roller linear guideways deliver high precision and high speed, reducing both cutting and non-cutting times.

Main Unit Cooling/Tailstock

The machine has been designed and built to minimize thermal displacement and maintain good precision over long periods of operation.

Reduced Thermal Displacement by Oil Cooling: The spindle and ball screw axis cooling system reduces thermal displacement during long machining times for high precision machining.

Processing Range

Featuring a special structural design, it enables turning of larger diameters for machining oversized workpieces.
Expanded Machining Range: The extended range accommodates diverse machining needs for large and long components, while also facilitating user access for internal debugging.

CONTROL SYSTEM

Optional Control System

SINUMERIK ONE Expandable HMI Series

ATC

Automatic Tool Change

The tool magazine, with a capacity of 60 tools, can be increased to 120 tools
ATC Operator Panel: The status of the ATC and tool magazine can be viewed on the touch screen, and the touch screen can also be used to manually operate the ATC, tool magazine, and tool holder brackets.
