The Importance of Concentric Construction
The
concentric construction of Govro machining units combines air
thrust, hydraulic control
and
positive stop—all on
the spindle centerline. Concentric design minimizes quill deflection,
affords longer life for the unit, tools and bushings, while
assuring uniformly accurate parts. The closed circuit hydraulic
system, always under pressure, prevents chips and coolant from
entering the system and automatically adjusts for oil seepage
to lubricate seals for longer life. The hydraulic feed control
has no axial backlash, minimizing the ‘drill drive’ at
breakthrough—which may occur with a mechanical system. |
