High Speed Electrode Machining Center (Electrode Machine)

Designed and Built for Precision Graphite and Copper Electrode Production

The Sodick TT1-400A is the ideal solution for precision graphite (graphite milling) and copper (copper milling) electrode production; designed to achieve maximum speed and acceleration by utilizing the latest in motion control and linear motor drive technology.

Sodick, a manufacturer of high precision machining centers since 1988, developed the TT1-400A based on the advanced core technologies incorporated in the company's highly renowned and successful HS Series.  The TT1-400A, which was built in Japan, shares the same ultra precise motion control and linear motor drive platform.  This technology developed in Sodick's Research and Development facility in Silicon Valley, California is testimony to the TT1-400A's capability to produce high precision electrodes at incredible speeds while maintaining accuracy.

Detailed Product Descriptions

40,000 RPM HIgh Speed Spindle (HSK-E25)

When designing the high-speed, high torque spindle, Sodick drew on its in-depth expertise in high-speed machining.  Every aspect of the design was revised for longer spindle life and to enable high-speed, high-precision direct milling of graphite and copper electrodes.

Accuracy and Rigidity are Delivered Though Machine Construction

With Linear Motors and Linear Scales included as standard equipment, actual static accuracy measurements of the TT1-400A are as follows:

Positioning Accuracy........................................within 3μm (0.00012")

Full Stroke Repeatability...................................within 3μm (0.00012")

Circular Cutting (1.575" dia. @ 400 ipm).............within 3μm (0.00012")

Sodick uses THK Linear Motion Guides to further enhance the performance of the Sodick TT1-400A.  The benefits of the THK Linear Motion Guides include:

High Radial Load Capacity

Highest Speed Capacity and Rigidity

Vibration and Shock Resistance

High Rotational Accuracy

All Axes Driven by Sodick Rigid Linear Motors

Sodick introduced their first Rigid Linear Motor Driven machines in 1999, replacing the dated ball screw technology at the time.  With over 35,000 rigid linear motor machines delivered, Sodick has perfected this technology.  The TT1-400A benefits from the advantages of rigid linear motor drives, including; no balls screws, no backlash, no lost motion, increased cutting speed and no maintenance. Rigid Linear Motors are the ideal solution for graphite milling.
