TURRET

TM 9-3417-213-14 & P

INSTRUCTION MANUAL

CAUTION

When returning head to vertical position, sweep the table with an indicator

attached to spindle to make sure head is square to table.

2. To tilt head from side to side, loosen the hex nuts which clamp the head to the overarm or the machine

column (whichever the case may be). Then tilt head the desired amount by applying crank to the sidewise

tilting worm stud at the right to the rear of the spindle head.

CAUTION

When returning head to vertical position, sweep the table with an indicator

attached to spindle to make sure head is square to table.

The back to front position of the head and overarm is readily changed by loosening the 4 hex nuts which clamp

the overarm to the turret. Apply a crank to the overarm adjustment shaft extension and move to desired position.

J. TURRET (Vertical Mill) : (See Drawing 101-112-101)

To index the entire turret-overarm-head assembly loosen the 4 hex nuts, 2 on either side of the overarm which

clamp the turret to the top of the column. Then swing the turret to the desired position and reclamp.

NOTE

It is highly recommended that all clamping nuts and bolts (turret to column,

overarm to turret, head side-wise tilt and head forward-back tilt) be securely

tightened before any machining cuts are taken. Always check these points before

starting a cut. Also, when returning overarm to normal position, attach an

indicator to the overarm, and slide the overarm in and out, with the indicator riding

against a square, which has been squared to front of table to make sure overarm is

square with table.

K. TURRET (Horizontal Mill) : (See Drawing 101-180-101)

1. The turret can be rotated on the column a full 360 .

2. The locating pins are effective only when the ram is used with the overarm support for the horizontal

spindle. The vertical spindle at this time would be at rear of machine. It may be necessary to tilt the vertical

head slightly for clearance at the rear of the machine when the machine is set for horizontal milling with a

long milling cutter arbor.

NOTE

It is highly recommended that all clamping nuts and bolts (turret to column,

overarm to turret, head side-wise tilt and head forward-back tilt) be securely

tightened before any machining cuts are taken. Always check these points before

starting a cut.

Also, when returning overarm to position for vertical milling, attach an indicator to the overarm, and slide the

overarm in and out, with the indicator sliding against a square which has been squared to front of table to make

sure overarm is square with table.

3. The complete horizontal spindle, turret, overarm & arbor bearing may be positione d 30 either side of

normal horizontal milling position by loosening the four 5/8 hex. hd. screws (two on either side of the

spindle, slightly below the C/L of the spindle) and swing the entire top unit to the desired angular position.
