New ROMI VTCs Designed for High Speed Tapping

Romi Machine Tools, Ltd introduces the VTC 30A/30B vertical tapping centers (VTCs). "The VTCs are a flexible, efficient and accurate solution for mixed volume, short-run operations as well as dedicated high-volume applications," said a Romi spokesperson. "Tool room and production facilities alike, as well as the many current Romi turning and milling machine users, are candidates for the new VTC 3OA/30B."

The VTCs combine high performance and rigid tapping capacity within a compact 44.8" x 84.64" space-saving footprint. Rapid traverse rates of 1,653 IPM (X- and Y-axis) and 1,772 IPM (Z-axis) mean accelerated machine cycle times and reduced non-cut time which increases overall throughput. Programmable milling speed is 394 IPM.

Servomotors directly coupled to high-precision ball screws provide acceleration and deceleration performance as well as precise feed movement. Also minimizing cycle time is an automatic toot turret with 10-tool capacity on the VTC 30A and a fast 1.3 second station-to-station index time.

The VTC 30A/30B cast mono-block bed design supports the vertical headstock and table, providing vibration dampening and the rigidity and stability required for today's heavy tapping needs. The headstock and table travel on automatically lubricated ball screw-driven linear guides for precise positioning, accuracy and repeatability.

The spindle

The headstock with main spindle is supported by precision bearings designed to operate at high speeds. A new pulley and poly-V belt heavy-duty headstock features a high-torque 7.5 HP GE AC high-precision spindle motor with power transmission efficiency and low noise level. The ISO 30 spindle achieves speeds ranging from 8 to 8,000 RPM (optional 12 to 12,000 RPM). The headstock has been specifically designed to provide rigidity for precision tapping, even during full-power machining in steel. Maximum rotation for rigid tapping is 394 IPM. Drilling capacity: aluminum Al-A4 13.1, 1/02"; GG 20, 0.94"; SAE 1045, 0.86". Threading: aluminum Al-A41 3.1, 0.79"/M20; GG 20, 0.63/ M16 and SAE 1045, 0.55"/ M14.

The table

The table work surface is 19.68" x 12.59". X-axis travel is 17.32", Y-axis travel is 11.42" and Z-axis is 10.62". Accuracy of positioning (X-, Y-, Z-axis) is 0.00019", and repeatability (X-, Y-, Z-axis) is 0.00012".

A fully automated lubrication system and coolant system, and complete machine enclosure with front and side doors for easy access to the work area are standard.

The control

The GE Fanuc 21i MB features a 10.4" color LCD and full swiveling keyboard. A shock absorber keeps the control in position when keys are pressed.

As the Romi VTC 30A/30B is generally used as a production machine, 2li MB can be programmed offline or online using G code language and standard G code features available from GE Fanuc.
