ROUNDTOP MACHINERY INDUSTRIES CO., LTD.
The fact that ROUNDTOP has had very rapid growth since our establishment has not changed our view that every day is an opportunity for even greater achievement. In 1979 we were producing only one model of conventional milling machine. Now we are one of the most diversified manufacturers producing vertical machining centers, horizontal machining centers, double column machining centers, Multi-Axis/5-Face Machining Centers, vertical turning centers, high speed machining centers and CNC lathes.

Features

  1. The C - axis feed pinion has a backlash - free wind-up mechanism for accurate table indexing. The positioning is detected by rotary encoder, accurate table indexing is possible. In the lording mode, this pinion is released by the hydraulic shifting gear located the C - V axis feed gear box.
  2. Live tooling: Face milling, End milling, Drilling, Boring and Turning.
  3. A spindle motor is located on top of the ram to rotate the spindle.
