Machining
- ANS-rotate index head until both graduated scales are at 0
1,00 rpms.
Micromoter stop collar all the way to the bottom fpr 2/3 center drill taper.
lock quill lock and move micromoter stop collar to top and rotate clockwise with thumb to
remove looseness.
Center drill 2nd hole till top micromoter stop collar makes contact with bottom (all holes have
same depth)
\. A maximum facing cut of ______ should be taken at a time - ANS-.025
\A 35-degree cutting tool is used to face off the part at 654 RPM's. (True or False - ANS-true
\A Digital Readout is used to show the ______ of the tool relative to the work piece -
ANS-location
\After completing the facing operation during the ______ cut, the operator should move the
cutting tool to the right & away from the part - ANS-final/last
\After cutting a diameter toward the left of the part on the final cut, the cutting tool should be
pulled toward the operator away from the part. (True or False - ANS-true
\bottom of part - ANS-set graduated scale to degrees
center drill 2/3 taper at 90 degrees apart
put number 6 drill bit n, 0 elevation handle, raise elevation, do all 4 holes
countersink all 4 holes to a shallow depth of 15 thousandth
\Bumping the lower part of the edge finder with your finger will cause it to ______ enabling a
better view when contacting the tool & locating it at the proper zero-point position to the part
- ANS-wobble
\Chamfer the gear blank with a 45-degree cutting tool. (True or False - ANS-true
\countersink 4 holes - ANS-speed at low range and low RPMs
Index 90 degrees
\drill 1/8 inch registration hole - ANS-range lever to high
micromoter stop collar at lowest position
do only one hole
\drill 23/32 holes - ANS-apply oil and drill 4 holes to proper depth with micromoter stop collar
and 90 degrees apart.
\drilling 4 holes and counterboring gear blank - ANS-2 parallels slightly below the surface of
jaws.
put gear blank on top and tighten with chuck
find edge of part with edge finder
index head at 0 degrees while locking x and y axis. (800 rpms)
center drill at 0 degrees to 2/3 depth of taper all holes at 90 degrees apart
purpose of center drill is to ensure drill bit that is used later will start precisely at center drill
hole. will prevent drill bit from walking/sliding across the top of the part
apply oil and use a 17/64 drill bit on all 4 holes (remove parallels
use spener wrench to loosen spindle lock knot and insert inmill then do 3 strike test
countersink all 4 holes at 150rpms at a depth of 15 thousandths
\drilling center drill holes - ANS-slide micromoter stop collars together and tighten
0 graduated scale on elevated handle
