Haas CNC Mills are intended for cutting and shaping of metals and other hard materials. They are general purpose in nature and a list of all of those materials and types of cutting would never be complete. Almost all cutting and shaping is performed by a rotating tool mounted in a spindle. Rotation of the mill is not required. Some cutting operations require liquid coolant. That coolant is also an option depending on the type of cutting.

Operations of Haas Mills are separated into three areas. They are: Operations, Maintenance, and Service. Operations and Maintenance are intended to be performed by a trained and qualified machine operator. This Operator's Manual contains some of the information necessary to operate the machine. All other machine operations are to be considered Service. Service is only to be performed by specially trained service personnel.

1. Machine Setup
   • Machine setup is done to initially set up the tools, offsets, and fixtures required to perform a repetitive function that later is called machine operation. Some machine setup functions can be done with the door open but are limited to “hold to run”.
2. Machine operating in Automatic Mode
   • Automatic operation is initiated with Cycle-Start and can only be done with the doors closed.
3. Operator loading and unloading of materials (parts)
   • Parts loading and unloading is what precedes and follows an automatic operation. This must be done with the doors open and all machine automatic motion is stopped when the door is open.
4. Operator loading and unloading of cutting tools
   • Tool loading and unloading is done less often than setup. It is often required when a tool has become worn and must be replaced.

Maintenance only consists of the following:

1. Adding and maintaining condition of coolant
   • Adding coolant and maintaining coolant concentration is required at regular intervals. This is a normal operator function and is either done from a safe location outside of the work enclosure or with the doors open and the machine stopped.
2. Adding lubricants
   • Adding lubricants for spindle and axes is required at regular intervals. These are often months or years in length. This is a normal operator function and is always done from a safe location outside of the work enclosure.
3. Cleaning chips out of the machine
   • Cleaning out of chips is required at intervals dictated by the type of machining performed. This is a normal operator function. It is performed with the doors open and all of the machine operation is stopped.

Service only consists of the following:

1. Repairing of a machine that is not operating correctly
   • Any machine that is not operating correctly requires service by factory trained personnel. This is never an operator function. It is not considered maintenance. Installation and service instructions are provided separately from the Operator’s Manual.
2. Machine moving, unpacking, and installation
   • Haas machines are shipped to a user’s location almost ready to operate. They still require a trained service person to complete the installation. Installation and service instructions are provided separately from the Operator’s Manual.
3. Machine packing
   • Machine packing for shipment requires the same packing material supplied by Haas in the original shipment. Packing requires a trained service person to complete the installation. Shipping instructions are provided separately from the Operator’s Manual.
4. Decommission, dismantle and disposal
   • Machine is not expected to be disassembled for shipment; it can be moved in its entirety in the same manner in which it was installed. Machine can be returned to the manufacturer’s distributor for disposal; manufacturer accepts any/all components for recycling per Directive 2002/96/EC.
5. End-of-life disposal
   • End-of-life disposal must conform to the laws and regulations in the region the machine is located. This is a jointly the responsibility of the owner and seller of the machine. The risk analysis does not address this phase.

DANGER: Do not enter the machining area any time the machine is in motion, or at any time that machine motion is possible. Severe injury or death may result. Motion is possible when the power is on and the machine is not in [EMERGENCY STOP].

Basic safety:

• This machine can cause severe bodily injury. 
• This machine is automatically controlled and may start at any time.
• Consult your local safety codes and regulations before you operate the machine. Contact your dealer if you have questions about safety issues.
• It is the machine owner’s responsibility to make sure that everyone who is involved in installing and operating the machine is fully acquainted with the operation and safety instructions provided with the machine, BEFORE they work with the machine. The ultimate responsibility for safety rests with the machine owner and the individuals who work with the machine. 
• Use appropriate eye and ear protection when you operate the machine. 
• Use appropriate gloves to remove processed material and to clean the machine. 
• Replace windows immediately if they are damaged or severely scratched. 
• Keep the side windows locked during operation (if available).

Electrical safety:

• The electrical power must meet the required specifications. Attempting to run the machine from any other source can cause severe damage and will void the warranty. 
• The electrical panel should be closed and the key and latches on the control cabinet should be secured at all times, except during installation and service. At those times, only qualified electricians should have access to the panel. When the main circuit breaker is on, there is high voltage throughout the electrical panel (including the circuit boards and logic circuits) and some components operate at high temperatures; therefore, extreme caution is required. Once the machine is installed, the control cabinet must be locked, with the key available only to qualified service personnel. 
• Do not reset a circuit breaker until the reason for the fault is investigated and understood. Only Haas-trained service personnel should troubleshoot and repair Haas equipment. 
• Do not press [POWER UP] on the control pendant before the machine is fully installed.

Operation Safety:

DANGER: To avoid injury verify that the spindle has stopped turning before opening the doors. In the event of a loss of power the spindle will take much longer to coast to a stop.

• Do not operate the machine unless the doors are closed and the door interlocks are functioning correctly.
• Check for damaged parts and tools before you operate the machine. Any part or tool that is damaged should be properly repaired or replaced by authorized personnel. Do not operate the machine if any component does not appear to be functioning correctly.
• Rotating cutting tools can cause severe injury. When a program runs, the mill table and spindle head can move rapidly at any time.
• Improperly clamped parts machined at high speeds/feeds may be ejected and puncture the enclosure. It is not safe to machine oversized or marginally clamped parts.

CAUTION: Manual or Automatic closing of the enclosure doors is a potential pinch point. With Auto Door, the door may be programmed to close automatically, or by pressing the door open/close button on the operators pendant. Avoid putting hands or appendages in the door while closing either manually or automatically.

Release of person trapped in the machine:

• No person should ever be located inside the machine during operation. 
• In the unlikely event that a person is trapped inside the machine the emergency stop button should be immediately be depressed and the person removed. 
• If the person is pinched or entangled the machine should be powered off; then the machine axes can be moved by use of a large external force in the direction required to free the person.

• Of the chip conveyor - Follow the cleaning instructions on the Haas service site (go to www.haascnc.com click on the Service tab). If necessary, close the doors and reverse the conveyor so the jammed part or material is accessible, and remove. Use lifting equipment or get assistance for lifting heavy and awkward parts. 
• Of a tool and material/part - Close the doors, press [RESET] to clear and displayed alarms. Jog the axis so the tool and material are clear.
• Of the Automatic Tool Changer/tool and spindle - Press [RECOVER] and follow the on-screen instructions.
  
• If the alarms do not reset or you are unable to clear a blockage, contact your Haas Factory Outlet (HFO) for assistance.

Follow these guidelines when you work with the machine:

• Normal operation - Keep the door closed and guards in place (for non-enclosed machines) while the machine operates. 
• Part loading and unloading – An operator opens the door, completes the task, closes the door, and then presses [CYCLE START] (starting automatic motion). 
• Machining job set-up – When set-up is complete, turn the set-up key to lock out set-mode and remove the key. 
• Maintenance / Machine Cleaner– Press [EMERGENCY STOP] or [POWER OFF] on the machine before you enter the enclosure.

Periodic inspection of machine safety features:

• Press any of the Emergency Stop buttons to verify all motion is stopped and a 107 EMERGENCY STOP Alarm is displayed.
• A monthly inspection of each Emergency Stop button should be performed.
• Inspect door interlock mechanism for proper fit and function.
• Inspect safety windows and enclosure for damage or leaks. 
• Verify all enclosure panels are in place.

Door Safety Interlock inspection:

• Inspect the door interlock, verify the door interlock key is not bent, misaligned, and that all fasteners are installed.
• Inspect the door interlock itself for any signs of obstruction or misalignment. 
• Immediately replace an components of the Door Safety Interlock system that do not meet this criteria.

Door Safety Interlock verification:

• With the machine in run mode, close the machine door, run the spindle at 100 RPM, pull the door and verify the door does not open.

Machine Enclosure and Safety Glass inspection and testing:

Routine Inspection:

• Visually inspect the enclosure and safety glass for any signs of distortion, breakage or other damage. 
• Replace the Lexan windows after 7 years or if they are damaged or severely scratched. 
• Keep all safety glass and machine windows clean to allow proper viewing of the machine during operations. 
• A daily visual inspection of the machine enclosure to verify all panels are in place should be performed.

Testing of machine enclosure:

• No testing of the machine enclosure is necessary.
