Engine lathe with 3 hp motor
Machinability of overlay coatings which are cut with engine lathe is investigated. Five kinds of thermal spray materials are used; 13% chromium stainless steels made in U. Machinists and maintenance shop personnel must be thoroughly familiar with the lathe and its operations to accomplish the repair and fabrication of needed parts. Machines 352" and shorter, however, were designed without any provisions for adding a bed extension. These single piece beds had cast end sections with recessed screw barrels and way projections that made it difficult to interface with the normal bed extension.
Machine shops with lathes will generally have several engine lathes to do the bulk of their work and, if at all, they will typically have only one turret lathe. Because engine lathes are inexpensive, as compared to turret lathes, hourly operation costs are lower.
Drills, gimlets, and augers, however, have cutting edges that detach material to leave a hole. A drilled hole is . Drill bits can be fixtured in the tail stock to cut axial holes in a turned part. These central holes are more accurate than a drill press or mill could provide since the lathe is dedicated to operations in which an axially-symmetric part is rotated about its central axis. Drill a 1/4" hole in each foot, placing it well out toward the end so that screws may be put in easily. Next mark and centre punch the bosses on each side exactly in line with the centre of the cylindrical portion of the field, that is, the magnet core.
Drilling is another operation, which can be conducted on a lathe with the holes accurately aligned with the centre axis of the part. Boring is similar to drilling in that a hole is made through the centre of the part but with boring, the hole is enlarged with the tip of the tool being extended into the hole and wound outwards.
