Standard Features
 
The MQ-8 Servo is the smallest mechanical quill unit that Drillunit builds. Since the front housing is just 4.25" wide, the MQ-8 fits into tight production setups. Yet, still achieves spindle speeds up to 6000 rpm and 8" of quill extension.

Drillunit utilizes its unique ballscrew/quill assembly to provide high-stability centerline thrust. The 2.250" diameter quill has a hardened and precision ground ballscrew around its circumference. The spindle is driven through the center of the ballscrew/quill assembly. This design affords high quill support -1:1 engagement vs. projection ratio -even when the quill is fully extended.

The MQ-8 mechanical quill unit is produced with a fine-grain iron casting that provides the rigidity and stability needed for quality operations. Drillunit will supply the MQ-8 completely ready for production.

The unit utilizes a servo motor for attaining an easily adjustable range of feed rates. This unit also features the following items as standard equipment; choice of three spindle constructions w/ ceramic coated seal diameter, motor bracket assembly, enclosed belt guard, timing belt drive, and three commercial epoxy filled limit switches.
