Hybco Model 6000
Drill Point Grinding Attachment
The Model 6000 drill point grinding
attachment provides circular, axial and oscillatory motions that operate
separately or together to generate the geometry needed to re-sharpen and or
produce special drill points as well as re-sharpen other types of face cutting
tools such as taps, step drills, counter sinks, reamers and core drills.
Some of the unique features of the
largely cast iron constructed Hybco Model 6000 are:
A six jaw Ajust-Tru chuck with
2" long bearing length; repeatability guaranteed to .0005 or less and the
thru hole is 1-1/4".
The spindle has a 5C-collet
A dial indicator shows the exact
amount of adjustable axial caming motion, eliminating the need for offset tool
projections for diameter changes.
Adjustable height timing gauge
for chisel point angle modifications.
The spindle is mounted on special
Timken "0" precision taper roller bearing.
The attachment features a D.C.
1/40 HP motor drive package featuring quick acting engagement with toggle
The oscillating motion is
generated from a drive gear mounted on the spindle which in turn drives a
circular turning crank arm that is attached to the lever arm. This motion is
engaged by inserting a "T" handle taper end wrench to lock the lever
arm into place.
The axial motion is on preloaded
cross roller bearings and ways.
The Model 6000 fixture can be
mounted on many different makes of tool and cutter grinders.
