For machining short work pieces, the operator may mount the work pieces on the table to machine simultaneously.

This machine is excellent for machining extra-long work pieces with only one setup. Suitable machining includes milling, drilling and tapping. With such machining nodes, you can save considerable time.

With this mode of machining, greater efficiency can be obtained.

• Single block processing time: 4 ms.
• Date memory: 2GB
• HMI:SINUMERK operation.
• Includes dynamic element and cycle-support of SINUMERK program GUIE.
• Tool and Zero Point Management: With tool life monitoring and graphic display. Also, including tools management for various types of tools.
• Program management: Equipped with SINUMERIK technical cycle and G code, and program GUIDE for program setting including dynamic element and quick browsing of graphics.
• Simulation: Employs top view and other view and other views of drawings for simulating machining processes.
• Single Block Search: for moving program to any section with or without calculation and execute program from this position to continue machining.

After each machine has been assembled, our experienced personnel applies a Laser interferometer to inspect and calibrate ball screw pitch error and backlash, positioning accuracy, as well as repeatability on the X, Y and Z-axes. Through the laser inspection process, we can guarantee high feed accuracy on three axes as well as overall machining accuracy.

To assure the highest structural mechanical assembly accuracy, and to eliminate the reverse spike phenomenon, all Bar tested during the assembly processes. The test will calibrate the machine to the optimum status, thus extend the life time of axial ball screw and slideways.

Machines are equipped with Syntec PC-Base CNC controller, featuring easy to learn and easy to operate. Mitsubishi, Fanuc or Siemens controller is optional.

The X-axis movement is driven by a servo motor and transmitted through high precision ball screw with gear reducer. This special design not only produces powerful driving force, but also provides high positioning accuracy on the X-axis.

The X-axis is transmitted through a ø80 mm extra-large ball screw, which is supported by two blocks to improve self-deflection of the screw. This help upgrade positioning accuracy on the X-axis.
