Hammer Mill Machine: The Ultimate Buying Guide in 2025 – AIPAK

POWER: All Haas machines operate on three-phase power, either low-voltage (220V) or high-voltage (400V or 440V). The machine may be built with either a low-voltage transformer or high-voltage transformer, but external step-up or step-down transformers can be used to match the machine to your shop’s power.

If you are installing multiple machines, or plan to have multiple machines in the future, make sure your shop has enough incoming power to support your plans. This is often overlooked when selecting a building for your machine shop.

You will need to have an electrician properly run power to the Haas machine prior to installation. This is necessary to ensure that all local codes are met, and that proper power is supplied to your Haas machine. Some of our smaller machines, such as Toolroom Mills, Toolroom Lathes, and standard Mini Mills, can operate on single-phase power, while other machines require three-phase power. Be sure to check how much power your machine requires.*

SPACE: Machine tools are big and heavy, and once in place, they aren’t easy to move around. A Machine Layout Drawing is available for all Haas machines, which includes all of the necessary exterior and interior dimensions of the machine. Use this to help lay out your shop and decide machine placement. The general rule of thumb is to make sure you have about 3 feet of space behind the machine, and at least 4 feet of space on all other sides. The space behind the machine is critical, so that the electrical cabinet can be opened fully. This is also the location for the incoming power. Your electrician will need to know this location to properly run the electrical supply to the machine. The location of the chip discharge will vary by machine. You definitely want to take this into consideration for machine placement.

Other things to consider for machine placement are the locations of the doorways into your shop. Most machine shops have large roll-up doors to the outside. Be careful where your machine is placed in relation to these doors, as they can allow large temperature swings in the shop. While the Haas machine has built-in thermal compensation to adjust for normal temperature effects, large thermal changes are not easily compensated for.

If your machine accommodates large workpieces, you’ll need to consider a location with additional space for loading material into and out of the machine. A lift device, such as the Haas Shop Lift or a fork lift, may be necessary to load and unload the machine.

WATER: If you are using coolant, you will need a water supply. Preferably, as close to the machine as you can get. Coolant is supplied as a concentrate, and then mixed with water. As the machine operates, some of that water evaporates, which changes the coolant concentration. A good refractometer will help you monitor and maintain the proper coolant concentration for optimal performance.

Maintaining coolant typically means adding water to the existing coolant in the tank, mixing it up, and then measuring the concentration. Another option is to install a Haas Automatic Coolant Refill System. This system automatically mixes a precise amount of coolant concentrate with water and dispenses it directly into your coolant tank. To make the most of this option, and simplify any coolant maintenance, there should be a water supply close to the machine.*

AIR: All Haas machines require compressed air to operate. Air is used for tool changes, turret clamping and unclamping, and other machine operations. The quality and quantity of air entering your machine are critical. The air must be clean and dry, and there must be sufficient volume and pressure for proper machine operation.

It is very important to have a high-quality air compressor for machine operation. A screw-style compressor with an air dryer is preferable, but a multi-stage piston-style compressor will work. While the Haas machine has a built-in system for removing water from the incoming air, the cleaner and dryer the air is before getting to the machine, the better off you will be. Of all your initial investments beyond the Haas machine, a high-quality air supply system is the most important. Avoid costly repair bills and premature failure of pneumatic components by ensuring clean, dry air is supplied to your machine.*

TOOLHOLDING: Again, this will vary, but here are the basic toolholders to consider for a mill: 1/2" and 1/4" end mill holders, keyless drill chucks, and ER32 collet chucks and a collet set. A full suite of toolholders would include multiple ER16, ER25, and ER32 collet chucks, along with the corresponding collet sets. Most collet sets come with the necessary wrenches. Pull studs will also be required. A tool-tightening fixture is included on most Haas mills, but a good bench-mounted version is also handy to have. Haas lathes come with a basic set of toolholders, but some ER collet chucks and straight shank collet holders will round out your starter tooling.
