Step 1:

The machine axes and setting station are in the pallet change position.

Step 2:

The setting station pallet and work area pallet are unclamped.

Step 3:

Fluid is supplied to the raise side of swivel traverse raise lower hydraulic cylinder which in turn raises the pallets.

Step 4:

When fully raised, the swivel traverse raised proximity switch is on.

Step 5:

Fluid is supplied to the rotate swivel traverse which in turn rotates the pallet changer.

Step 6:

The speed is reduced approximately 100.00 mm away from the alignment pin, when the directional control valve (rollers) are actuated (closed) by the cam lobe ramps.

Step 7:

When the directional control valve (rollers) are actuated (closed), all return line fluid is then diverted through the appropriate flow control valve which reduces the pallet changer rotational speed.

Step 8:

When fully rotated, the swivel traverse position 1 or 2 proximity switch is on.

Step 9:

Fluid is supplied to the lower side of the swivel traverse raise lower hydraulic cylinder which in turn lowers the pallets.

Step 10:

When fully lowered, the swivel traverse lowered proximity switch is on.

Step 11:

The setting station pallet and work area pallet are clamped.
