The Ryazan Machine Tool Plant offers the RT950F4-6.5 four-way bed CNC lathe, which is suited for turbine repair and the wind power industry. The four-axis lathe has a 74" swing and 256" between centers. Workpieces can weigh as much as 35 tons without steady rest support or 40 tons with a single steady rest. The bed design allows the carriage to pass both steady rests and tailstock without disturbing a setup, the company says.

The company says Fanuc Oi four-axis control and Fanuc drives and motors should make this model attractive to a large number of shops in the United States. The fourth axis has a 25-kW (30-hp) ISO 50 taper milling head with Y-axis vertical travel, allowing contour milling of slots, keyways, splines, bolt patterns and more. The milling head can be removed and replaced with the included heavy duty H4 auto-index turret head.

The lathe features a double rack-and-pinion Z-axis drive with scale feedback. This allows for high accuracy and virtually unlimited center distance. Its heavy-duty tailstock has powered body travel, powered quill travel, powered way clamping and built-in live spindle bearing with load monitor.

This machine can run for a long time without any operator intervention, and users can machine finished parts from slug stock or cast blanks while achieving the same high productivity as if they were machining from barstock, the company says.
