Head swivel

First, remove the knock pin at the front right side of the head using the accessory knock pin puller. Next, loosen the two head swivel clamp bolts. Do not pull them out. Then, insert the accessory crank handle into the front hexagonal head (head swivel shaft) and swivel the head in accordance with the swivel angle dial.

After swiveling the head to the desired angle, clamp it by tightening both head swivel clamp bolts equally at the top and at the bottom.

Since the head stock pin alone cannot ensure precision, always check the angle using the swing check on the table. The head swivel should revert to 00.

9.9. Ram transverse movement

The ram can be moved transversely (535 mm [21”]) by hand. First, loosen the two ram clamp bolts at the right side of the swivel base. In this state, the ram can be moved transversely by inserting the accessory crank handle into the hexagonal head of the ‘ram transverse movement pinion shaft’ while operating the handle.

After moving the ram to the desired position, be sure to clamp it using the two ram clamp bolts.

9.10. Table manual feed

The table can be moved in three directions using the manual handle.

The table can be moved longitudinally using the handle at the front left side of the saddle.

The saddle can be moved transversely using the handle at the front right side of the knee.

The knee can be moved vertically using the crank at the front left side of the knee.

[Table longitudinal feed]

Loosen the two table clamp levers at the front of the saddle. Next, set the ‘table longitudinal feed direction change lever’ to the neutral position. Then, engage the table longitudinal handle clutch and turn the handle.

• When the feed handle is turned counter-clockwise, the table moves to the left.

• When the feed handle is turned clockwise, the table moves to the right.

The ‘table feed gauge’ should have an accuracy of 0.02 mm per division on the feed speed dial and the table should move at 4 mm per revolution.

[Table transverse feed]

Loosen the saddle clamp lever at the lower right side of the saddle, engage the transverse feed handle clutch, and turn the handle.

• When the feed handle is turned counterclockwise, the saddle moves forward.

• When the feed handle is turned clockwise, the saddle moves backward.

The ‘table feed gauge’ should have an accuracy of 0.02 mm per division on the feed speed dial and the table should move at 4 mm per revolution.

[Table vertical feed]

Loosen the two knee clamp bolts at the rear right side of the knee, engage the vertical feed crank handle clutch and turn the handle.

• When the feed handle is turned counterclockwise, the table moves downward.

• When the feed handle is turned clockwise, the table moves upward.

The ‘table feed gauge’ should have an accuracy of 0.02 mm per division on the feed speed dial and the table should move at 2 mm per revolution.

The ‘limit switch’ under the ‘table vertical feed handle’ secures the machine against damages caused by collision when the manual operation is being carried out. For safety, the lower and upper parts of knee are equipped with ‘stoppers’.

9.11. Automatic table feed

The table can be moved in longitudinal directions through the automatic feed operation.

Loosen the table clamp lever before operating the ‘table automatic longitudinal feed’. Press the “ON” push button ( ) at the top left side of the front operation panel to start the table feed motor. If the ‘longitudinal feed direction change lever’ at the center of the saddle is set to the right, the table will move to the right.

As for the automatic stop, a ‘stop dog’ is located on the front side of the table. When the ‘stop dog’ hits the rack that is connected with the ‘longitudinal feed direction change lever’, revert the lever to a neutral position to stop the table automatically. The table feed motor can be stopped by pressing the “OFF” push button ( ) that is located at the left side of the front operation panel.

[Setting of automatic feed speed]

To set the feed rate, 12 steps of speed change can be done through the ‘speed change wheel handle’ on the feed gear box at the lower left side of a saddle, and through the High / Low change knob operation.

[Mm / min]

No. 1 2 3 4 5 6

[60 Hz] H 720 507 342 267 187 127

L 87 61 41 32 22 15

H 600 420 283 221 155 105

[50 Hz]

L 72 50 34 26 18 12

[Feed rate list]

Set the feed change lever in the neutral position. Then, change the speed when the feed

motor turns. Push the knob in for low speed and pull it out for high speed.

<Feed speed dial handle>

<High-low change knob>

Change the ‘feed speed’ after setting the ‘longitudinal feed direction change lever’ to the neutral position. Changing the feed speed during an automatic feed adds an overload to the gear, and may cause its damage.

Operate the high-low change only in a low speed area (No. 1~3)

For the speed change wheel handle operation: Change from one level at a time. Extreme direct change (e.g. from the maximum speed (No.6) to the minimum speed (No.1) and vice-versa) cannot be performed.

9.12. Table rapid feed

The Table rapid feed is applied in the longitudinal, cross and vertical direction.

Longitudinal direction

When the table rapid feed lever on the feed gearbox is pulled up during an automatic feed, the table is fed at a rapid feed in the feed direction. The table transverse feed direction switch lever controls the feed direction. If this lever is pushed to the left, the table will move to the left. When released, the rapid lever gets lowered automatically and the feed returns to the cutting feed rate.

Cross Direction

The ‘table power cross feed operation’ is the same as the ‘longitudinal automatic feed operation’. If the transverse feed direction change lever is pushed lower, the table will move to the column side.

As for the automatic stop, the ‘stop dog’ is located on the side of the knee. When the ‘stop dog’ hits the lever of the ‘transverse feed direction change lever’, revert the lever to the neutral position to stop the table.

Vertical direction

Operating the push-button on the front operation panel performs this. While the upper “UP”

(/lower “DOWN”) push-button switch is being pressed, the rapid feed is applied in the table in the upward (/downward) direction. When the switch is released, the rapid feed stops at the place.

The ‘limit dog’ for upper or lower is installed at the right side of the knee. When the column side limit switch is operated, the motor power turns-off.

When performing the rapid feed, disengage the handle clutch by pulling the handle to disable the manual handle from turning.

There is a ‘clutch position detection’ limit switch for the knee vertical feed handle. When the handle clutch is engaged, the handle operates the limit switch so that the vertical rapid transverse cannot function.

9.13. Mounting / Dismounting of tool

< Mounting >

To mount a tool to the main spindle, follow the procedure below:

1. Be sure that the main spindle is turned-off. Move the quill to the upper end position and fix its position using the clamp lever.

2. Press the emergency stop button, and set cam switch to “0”

3. Set the spindle lever switch to brake “ ” position.

4. Match the driving key using the flange ditch. Press the “IN” button to mount it to main spindle.

• Always use standard tools.

• Never hold the edge of the cutting tool when mounting a tool.

• Before setting the tool in the main spindle, clean up the spindle taper and tool taper shank surface with a clean cloth to remove chips and dirt.

• Don’t operate the main spindle during work.

• Only use a right-sized spanner or wrench when mounting a tool to the spindle.

< Dismounting >

1. Be sure that the main spindle is turned-off. Move the quill to the upper end position and fix its position using a clamp lever.

2. Press the emergency stop button and set the cam switch to “0”

3. Set the spindle lever switch to the brake ( ) position.

4. Press the OUT button on the Auto draw bar panel and take out the tool carefully.

When the tool’s tapered part loosens-off from the main spindle, lock the nut with a bigger torque.
