Tailstock movement. General International 25-650ABC M1

TAILSTOCK MOVEMENT

The tailstock is used to support the other end of the workpiece to be turned and can be moved along the bed sideways to suit the length of the workpiece H.

To move the tailstock on the bed:

1. Loosen the tailstock locking lever I.

2.

Move the tailstock by hand to the desired location on the bed J.

3.

Retighten the tailstock locking lever to secure the tailstock in position.

ALIGNMENT BETWEEN CENTERS

There is a small amount of play built into the headstock on the bed to allow the headstock to pivot freely.

Whenever the headstock is pivoted back from the outboard position, the alignment between the headstock and tailstock centers should be double checked and adjusted as needed.

1. Pivot the headstock to its normal spindle turning position (0º) and lock it in place.

2. Install a spur center in the headstock and a live center in the tailstock.

3.

Release the tailstock locking lever and advance the tailstock on the bed A until the points of the 2 centers just barely touch each other.

4. Using the tailstock locking lever, secure the tail stock on the bed with the points still touching.

5. Look down at the two centers from above B to verify that the points are in alignment. If the points line up, proceed with normal turning operations.

6. If the points are not lined up release the headstock locking lever and manually adjust the headstock position using the play in the head- stock to line up the center points.

7. With the points lined up, hold the headstock in place and tighten the headstock locking lever.

8. With the points lined up, proceed with normal turning operations.

HEADSTOCK, TOOL REST CARRIAGE AND TAILSTOCK LOCKING LEVER

ADJUSTMENT

The headstock, tool rest carriage and tailstock assemblies use a cam action clamp to lock them in place along the bed ways. You may need to adjust the cam action to increase or decrease the clamping pressure. To adjust:

1. Loosen handle A, B and C until the component slides freely on the ways. Remove travel limiters D on the bed and slide the component off of the bed.

2. Using a 1- 1/16 th inch wrench or socket, tighten or loosen the nut that is located under the donut shaped wedge, E.

Turning the nut clockwise increases the clamping force and counterclockwise decreases the force.

NOTE: If using a socket with an extension, the component can be adjusted without removing it from under the lathe bed.

The (4) black locking levers that lock the quill, tool rests, and the motor tension feature ratchet style handles for easy positioning. Simply pull out on the spring loaded lever and move it to a different position, then release it and it will snap back onto the positive drive teeth.
