The
most noticeable feature is that the cast iron column and headstock
assembly travels in the Y axis on large dovetail slides that are
set well apart instead of the table having a Y axis. This gives
great rigidity to the whole assembly, plus using the otherwise
dead weight to absorb stresses caused by the cutting actions. This
design also gives extra rigidity to the table, having only travel
on the X axis. To add further to the function of the machine the
headstock travels vertically on its own dovetail on the column,
controlled with a lead screw and convenient control wheel, allowing
the headstock to be positioned exactly where you want it. The headstock
also pivots 45° either way to allow inclined machining or drilling. The quill shaft has a course or fine down feed control for use in drilling or milling operations.
A convenient digital read-out for the extension of the quill shaft is provided.
An advanced 700W DC brushless motor gives a variable speed of between 50 and 2500rpm monitored by a digital display. The motor speed is controlled by simple push buttons on the control panel, as is the forward/reverse rotation selection.
Another unusual feature is the tapping function. When selected, this allows the controlled tapping of holes, with the depth of thread if required, monitored on the quill DRO and instantaneous reverse by push button on each of the down feed handles. The electronics control the tapping speed to a maximum speed of 600rpm, but it is adjustable down to 50rpm. |
