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

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

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

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

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.

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]. 
  • The number of axis manifolds may be different on some machines.
  • 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].
  • There is (1) copper tube that goes to the ballnut and (1) copper tube that goes to each linear guide truck.

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.

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.
