CNT Motion CNT-950

CNT Motion Systems treats the table of the CNT Motion CNT-950 as something the customer decides. The specification list gives the cutting area as customer-specified, and the maker says it can build this model with virtually any table size. What is fixed is the motion system: servo motors on every axis, a helical rack and pinion on Y, Hiwin ball screws on X and Z, and a rapid traverse of 1,500 ipm (38.1 m/min).

Z-axis travel is 7 in or 11 in (178 mm or 279 mm). The shorter stroke suits sheet goods on a spoilboard. The longer one is for thicker blanks, fixtures or a tall vacuum pod setup, and it is the same figure the CNT-1000 lists as standard.

At approximately 2,500 lb (1,134 kg) the machine is the lighter of the two base routers; the CNT-1000 is listed at approximately 4,500 lb (2,041 kg) and 2,200 ipm (55.9 m/min). Listed repeatability, 0.001 in (0.025 mm), and positioning accuracy, ±0.002 in (±0.051 mm), are identical on both. So the choice between them is about how hard and how fast the machine will be pushed, and about floor loading, more than about the tolerance on a finished part.

The feature list on the page describes one configuration: a 60″ wide by 120″ long cutting area with an aluminium vacuum grid, a 12-HP ISO30 tool-change spindle with speed control to 24,000 RPM, a 12-station fixed tool bar and a 25-HP regenerative vacuum blower. The introduction, however, says to add a drill motor or spindle to the machine, so treat that list as an example build and confirm the contents of a quotation. A Windows11 PC with WinCNC software is the control.
