Model SB1001 8K™ Lathe

Chuck & Faceplate Mounting

This lathe is equipped with a D1-type spindle nose. This type of spindle uses camlocks that are adjusted with an 8mm hex wrench to securely mount a chuck or faceplate with repeatable precision and ease.

Never use spindle speeds faster than the chuck RPM rating or the safe limits of your workpiece. Excessive spindle speeds greatly increase the risk of the workpiece or chuck being thrown from the machine with deadly force!

This lathe is shipped with the 3-jaw chuck installed. This is a D1-3 scroll-type chuck where all three jaws move in unison when the chuck key is used.

A 4-jaw chuck generally features independent jaws, which are used for square or unevenly- shaped stock, and to mount work that needs to be adjusted to near zero total indicated runout.

If neither chuck can hold your workpiece, use a faceplate which has slots for T-bolts that hold standard or custom clamping hardware. With the correct clamping hardware, a faceplate offers a wide range of uses, including machining non- concentric workpieces, straight turning between centers, off-center turning, and boring.

See Accessories on Page 46 for available 4-jaw chuck and faceplate options from South Bend.

Chuck Installation

To ensure accurate work, it is extremely important to make sure the spindle nose and chuck mating surfaces/tapers are clean. Even a small amount of lint or debris can affect accuracy.

The chuck is properly installed when all camlocks are tight, the spindle and chuck tapers firmly lock together, and the back of chuck is firmly seated against the face of the spindle all the way around—without any gaps.

To install the chuck:

1.DISCONNECT LATHE FROM POWER!

2.Place a sturdy piece of plywood under the spindle to protect the bed ways during the installation process (see Figure 18).
