Machining

. A maximum facing cut of ______ should be taken at a time

.025

tapping threads into 4 holes

1 quarter 20 thread per inch tap tap shouldn't touch bottom of hole turn drill chuck and thread tap by hand with the milling machine off 10 quarter turns turning the tap backwards loosens it for the next rotation forward and prevents it from breaking don't let micromoter touch each other file off bearings on top of holes

drilling 4 holes and counterboring gear blank

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

final/last

When facing a part, the lathe is started and then the Power Feed Lever is engaged in the proper position. The ________ cut is made with the cutting tool moving in the forward direction, cutting to the center of the part and then stopped by returning the lever to the neutral or middle position

first facing

drill 1/8 inch registration hole

range lever to high micromoter stop collar at lowest position do only one hole

bottom of part

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

drilling center drill holes

slide micromoter stop collars together and tighten 0 graduated scale on elevated handle elevate mill table (1 full rotation = 1hundred thousandth) apply oil to drill bit before drilling holes rotate index head 90 degrees to drill next hole
