Vol. 6 Milling Machine 3
Duration 46:33 mp4 download 1 Milling Machine 3 Squaring a part, maching all surfaces so they are flat and perpendicular to one another and nominally to the part that will be milled; removing burrs 2 Squaring a Plate Squaring the sides of a part/plate to the dimensions of the finished milled part; remove burrs 3 Using the Edgefinder Used to locate the edge of a part relative to the spindle of the machine 4 Drilling Holes Drill press used to drill holes in parts; center drill milling and other drill bits; setting depth stop |

Vol.7 Milling Machine 4
Duration 45:33 mp4 download 1 Reaming Holes Reamer is used to make a drilled hole larger and smoother within 2/10000" of it's diameter 2 Boring Holes A Boring Head is used for making very accurate holes; also used on a quill producing more accurate holes 3 Milling a Slot End Mills used to mill slots in a piece 4 Milling a Shoulder Conventional & Climb Milling A Shoulder or step milled into a piece Conventional Milling-part is fed against the motion of the tool; best for rough cuts Climb Milling-Part is being fed along with direction or rotation of the tool; better surface finish cuts 5 Cleaning the Machine Very important in the use of milling machine; chips, dust, etc.. Needs to be cleaned Only a brush or vacuum should be used. Air should never be used; this risks blowing chips into machine and possibly damaging it Most accidents in a machine shop happen when bringing parts to a machine or when the machien is being cleaned |
