Note: The location of the grease reservoir is different on some machines.

The CALM - Haas Liquid Grease lubrication system is a restrictor grease flow system that pumps grease through flexible plastic tubing and copper tubes to the axes.

Use the illustration to identify the parts of the lubrication system.

Note: For recommended lubricant types, see Lubricant Table for Haas Machine Components.

1. Grease Pressure Switch - Monitors the grease system pressure and sends a signal to the control to generate an alarm if the pressure drops below the minimum level too quickly.
2. Grease Pressure Gauge - Shows the pressure (in psi and bar) of the grease system.
3. Grease Filter Wrench - Removes the grease reservoir.
4. Grease Reservoir Assembly - Stores the grease.
5. Air-Lube Panel Decal - Shows the color-coded cables that connect each solenoid.
6. Oil Reservoir - Stores the oil that lubricates the spindle.
7. Air Manifold Assembly - Supplies air to the machine.
8. Axis-Lube Air Solenoid - Pressurizes the grease reservoir.
9. Air Pressure Gauge - Shows the pressure (in psi and bar) at which the air is supplied.
10. Electronic Analog Air Pressure Sensor - Monitors the air system pressure and sends a signal to the control to generate an alarm if the pressure drops below the minimum level for a set period of time.

Axis Lubrication

The grease reservoir [1] lubricates the axes at a rate of (1) grease cycle for every 24 hours of axis travel.

Grease moves from the grease reservoir [1] through flexible plastic tubing [2] to the axis manifolds [3].

Note: The number of axis manifolds may be different on some machines.

Note: Each axis has (1) ballnut [4] and (4-6 ) linear guide trucks [5].

Grease moves from the axis manifolds [3] through copper tubes. The copper tubes lubricate the ballnuts [4] and the linear guide trucks [5].

Note: There is (1) copper tube that goes to the ballnut and (1) copper tube that goes to each linear guide truck.

Note: The Haas Liquid Grease canister lasts approximately 10 months to a year under normal machine operation, 8 hours a day and 5 days per week.

Axis Manifold Fitting Information

The Haas Liquid Grease lubrication system uses adapter fittings [1] in the axis manifolds. The linear guide trucks and ballnuts use restrictor fittings [2]. The restrictor fitting has a gap [4] between the threads and the set screw [3]. This forces the manifold-fed grease to pass through the gap [4] to lubricate the axes.

Note: The copper tubes on this system may or may not be equal length.

Caution: Do not change the length of the copper tubes or flexible plastic tubing. This changes the flow of grease.
