- Increases the "apparent" mass of the machine.
- Improves dissipation of machine vibrations into the foundation.
- Improves overall stability and can reduce re-leveling requirements.
- Prevents axis acceleration from moving the machine.
- Keeps the machine aligned with accessory components (Bar Feeder, Pallet Pool / Changer).
- May be required for certain machine models (DT/DM, EC-1600) or accessories like the Haas Bar Feeder.
Limitations of anchoring:
- Anchoring requires drilling into the foundation.
- Anchoring makes the machine installation process more expensive.
- Anchoring requires a proper foundation and properly set anchors.
- Anchoring makes it more difficult to move a machine to a different location.

An alternative to anchoring:
Most Haas machines now include cold-flow anchoring pads in place of the traditional leveling pads. These pads have a "cold-flow" material built into the bottom of each pad, which helps to improve the machine's connection to its foundation. The "cold-flow" material uses the machine's own weight to form an intimate connection between the bottom of the pad and the foundation's surface. This has several benefits:
- Cold-flow anchoring pads elminate the need for traditional machine anchoring, in most cases.
- Cold-flow anchoring pads reduce the cost of machine installation.
- Cold-flow anchoring pads make it much easier to move the machine to a new location.
Put the floor plate  and the 5/8 washer  on the long end  of the stud below the 5/8-11 hex nut .
Put the long end  of the stud into the coupler nut  until it stops.
Tighten the 5/8-11 hex nut  with your fingers. Make sure the floor plate  and washer  are tight against the coupler nut .
Mix the epoxy. Refer to the epoxy manufacturer’s instructions.
Fill the hole until the epoxy is approximately 2" (50 mm)  from the top of the hole .
Do these steps to make sure the quantity of epoxy is correct.
- Push the anchor assembly into the hole until the floor plate is against the floor.
- Pull the anchor assembly far enough out of the hole to see where the epoxy reaches on the coupler nut. If the quantity is correct, the epoxy stops at the approximate middle  of the coupler nut.
Put the anchor assembly into the hole. Make sure the stud  points up.
Make sure the stud is perpendicular to the floor. Use a carpenter's square .
Refer to the epoxy manufacturer’s instructions for the time to cure. The time to fully cure is typically 18-24 hours.
Tell your HFO that you have completed this task.
