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. Ergonomics-much easier to load / unload and set-up.
  2. Chip Removal-twin screw type conveyors plus a caterpillar conveyor ensure complete chip removal with little manual cleaning.
  3. Floor Space-Our double columns consume less floor space then a similar size VMC.
  4. Rigidity-Opposed to large VMC's with a very large spindle center to column distance, the DMC spindle is very close to the bridge for the best possible rigidity.
  5. Total Accuracy-Because the Y and Z axes have fixed loads at all times and the X axis carries the only dynamic load overall accuracy is improved over a conventional VMC.
