9.2 ST Series - Chip Conveyor - Installation

1. Conveyor Trough Cover
2. Drip Tray
3. Safety Skirt

Attach the trough cover [1] to the CHIP CONVEYOR.

For a Jorgensen conveyor, install the (8) hex head screws and washers to attach the trough cover and lock the conveyor in the operating position as shown.

For a Hennig conveyor, install the (4) hex head screws and washers to attach the trough cover and lock the conveyor in the operating position.

 Caution: The conveyor is heavy.

Put a piece of "1" bar stock [1] into the holes in the lifting tabs. Lift the CHIP CONVEYOR [A] with a lift strap on the bar stock and a forklift (not shown).

Raise the conveyor until it is level with lathe chip conveyor pocket.

 Note: For ST-40/45/40L/45L/50/55 machines with a 95 Gallon Coolant Tank proceed to the next step.

Push on the bar stock to move the conveyor into the machine. This may take (2) or more people.

 Note: This step applies to ST-40/45/40L/45L/50/55 machines with a 95 Gallon Coolant Tank.

• Lower the conveyor legs.
• Push the conveyor in until the conveyor legs almost touches the coolant tank.
• Remove the legs from the conveyor.
• Push the conveyor the rest of the way in.
• To prevent a coolant leak install the bolts back into the tapped holes.

 Note: This step applies to ST-10, ST-20, and ST-30 lathes only.

For a Hennig conveyor, install the (4) 1/4-20 X 1/2" button head cap screws (BHCS) to lock the conveyor in the operating position as shown.

For a Jorgensen conveyor, install the (2) 1/4-20 X 1/2" BHCS to lock the conveyor in the operating position.

 Note: This step applies to ST-10, ST-20, and ST-30 lathes only.

Install the trough cover [1] to the chip conveyor.

 Note: This step applies to both Hennig and Jorgensen conveyors.

Push the chip conveyor into the lathe.

Lift the chip conveyor.

Slide the drip tray under the chip conveyor to the approximate position shown in the figure.

 Note: No fasteners are needed to keep the tray in place.

For ST-40/40L models, unfold and lock the leg before operation. The leg height needs to be adjusted so that the casters touch the floor after the machine is leveled.

Open the cover at the head of the conveyor. Look at the belt tension as the belt goes around the sprocket.

Tighten the belt tensioning screws at either side of the conveyor head to adjust the belt drive shaft and remove slack from the belt.

 Note: Adjust the screws equally to keep the drive shaft perpendicular to belt travel.

While you adjust the belt tensioning screws, push up on the belt with a wrench at the head of the conveyor. Measure the belt slack [1] at the center of the belt in the lift section of the conveyor. The correct belt slack for Jorgensen conveyors is 0.25" - 0.38" (6 - 10 mm). The correct belt slack for Hennig conveyors is 0.12" - 0.25" (3 - 6 mm). Repeat step 2 as needed.

Apply the jam nut on each tensioning screw to lock it in place.

Install the access cover.

Attach the skirt [1] to the bracket [2].

Note: The seam [3] in the skirt faces the conveyor as shown.

Mount the bracket to the conveyor.

Connect the chip conveyor power cable to the connection terminal on the enclosure.

On ST-10 and ST-15 machines, the connection terminal is on the right side of the machine [1].

On ST-20 and larger machines, the connection terminal is on the back of the machine on the chip conveyor side [2].

Note: Make sure you are connecting the chip conveyor power cable to the correct terminal. You can identify the terminal by looking at the shape of the ground terminal [3].

When connecting in the power cable, push the male connector into the terminal, and then twist the connector clockwise [4] to lock the connection.

Note: If you have to remove the power cable at any time, you have to twist the connector counter clockwise before disconnecting.
