The Smithy Granite Series machine cuts threads to metric or inch standards. In thread cutting, the carriage carries the thread-cutting tool and moves by the rotating leadscrew. - Page 104 Granite 1300 Series Operator’s Manual The lathe spindle holding the workpiece revolves at a selected speed (revolution per minute, or rpm) according to the type and size of the workpiece. The leadscrew, which runs the length of the lathe bed, also revolves at the desired rpm. There is a definite and changeable ration between spindle and leadscrew speeds.

Page 107: How To Determine Speeds And Feeds For Milling
Set the direction of feed before you begin milling. Up milling, or conventional milling, is when the direction of feed is opposite to the direction of cutter rotation. Down milling, or climb milling, is when the direction of feed is the same as the direction of cutter rotation. Or Visit www.smithy.com... -
Page 108: Up Milling
Granite 1300 Series Operator’s Manual Up Milling In up milling, forces on the workpiece tend to pull it out of the vise or fixture holding it, so fasten it securely. These forces also push the workpiece away from the cutter, which eliminates backlash. - Page 109 4. grind the end clearance 5. grind the top rake, touching in a chipbreaker.

They include ball endmills, roughing endmills, dovetail endmills, T-slot cutters, keyseat cutters, and shell endmills. • Ball endmills cut slots or fillets with a radius bottom, round out pockets and bottoms of holes, and do diesinking and diemaking. -

• Single-angle cutters have one angular surface. Teeth are on the angular surface and the straight side, and they usually have 45° or 60° angles. • Double-angle cutters machine V-grooves.

Before attempting to cut a thread on a workpiece, cut a few practice threads on odd bits of steel, iron, and aluminum. Built for thread cutting, the Smithy Granite Series machine, cuts standard internal and external threads, as well as special threads. You may cut coarse or fine threads in a great range of threads per inch, in V or square shapes, in established profiles like Unified National, acme, and metric. - Page 117 Screw threads are usually referred to by pitch numbers, such as 18 or 24, meaning 18 or 24 threads per inch (tpi). The Smithy Granite Series machine cuts standard threads in pitches from 7 to 52 tpi and metric threads from 0.35 to 6.5 mm.

Granite 1300 Series Operator’s Manual Because the feed of successive cuts is toward, not away from the operator, the thread-cutting set is reversed. Also, you must take lighter cuts because of the cutter's extension from the toolpost. Take an extra finishing cut without changing the setting of the compound rest. -
