Standard Features
The MQ-120 & 140 unit are ball screw actuated
variable feed, quill type machining units. They are
ideally suited for single or multiple spindle applications on all types of metal removal machinery. The
unique arrangement of few moving parts in a compact assembly provides for versatility of application
and minimal maintenance in operation. Each unit
features a large 4.250” dia. hardened and ground
quill which carries the spindle assembly and the
ball screw nut. The excellent quill bearing area,
combined with the ball screw centerline thrust design, provide for extreme stability throughout the
unit stroke. A CNC servo motor drives the ball
screw and controls all functions of rapid traverse
and feed.
The flexibility of this drive is evidenced by the
many cycles that can be easily obtained with the
available control options , such as multi-stage feed,
back feed, pulse feed (chip breaking), gap jumping,
peck feed, and rigid CNC tapping thru synchronization of the feed and spindle motors. Standard,
quick-disconnect proximity switches control the
home position and over-travel limits. Internal
bumper cushions mechanically protect the unit
from over travel damage in both directions.

stations. The dual axis controls apply to both
drilling and tapping operations or combination
drilling and tapping cycles for use with combination drill/taps (draps). Standard CNC rigid tap
cycles include left or right hand threads and inch
or metric pitch. All cycles are stored as subroutines in system memory and recalled thru PLC
or HMI interface (multi-tasking).
