Chapter 1 - Safety

The general principles for safe operation of Milltronics machines are outlined in this

manual. Every Milltronics machine is engineered for safety. You will note, for example,

that all rotating parts are protected by specially designed covers. On some models, the

entire machine will be enclosed to protect the operator from flying cutting chips and to

prevent an insecurely clamped work piece from being thrown out during cutting

operations. If a Milltronics machine is operated in accordance with the manufacturer’s

instructions, it will provide safe and reliable service. However, with machines of this

nature, serious injuries or death can occur from careless or improper operation. Do not

attempt to operate this equipment without reading and thoroughly understanding this

manual. Not every example of improper operation or unauthorized usage that may lead

to malfunction or accident can be anticipated. If a particular operation is not

documented in this or any other Milltronics manual as authorized usage for the

particular equipment, it should be assumed that this is an unauthorized or improper

usage with potential danger and should be avoided.

A. This machine is provided with various safety devices to protect the operator and the

machine. However, these cannot cover all aspects of safety, therefore the operator

must thoroughly read and understand all machine manuals before operating the

machine. The operator should also take into consideration other aspects of safety

related to the particular environment and conditions.

B. Three categories of safety guidelines have been used throughout this manual:

DANGER, WARNING, and CAUTION. The Ansi Z535.4 safety alert symbols and

their meanings are as follows:

DANGER: Indicates a hazardous situation which, if not avoided, will

result in death or serious injury.

WARNING Indicates a hazardous situation which, if not avoided, could

result in death or serious injury.

CAUTION: Indicates a hazardous situation which, if not avoided, could

result in minor or moderate injury.

Safety Checklist

• Always observe the safety instructions inscribed on the safety labels fixed onto the

machine. Do not remove or alter these labels.

• Do not attempt to operate this machine until you have read the manuals supplied

with the machine and understand each of the functions and operation methods.

• Operators should be trained formally either by a technical school or some form of

apprenticeship program in machining and machining safety.

• Installation and maintenance should be performed only by qualified personnel.

• Qualified personnel shall be trained and knowledgeable of the construction and

operation of this equipment and work methods. Such persons shall be trained to

recognize and avoid hazards that might be present with respect to this equipment

and work methods. Such persons shall also be familiar with the proper use of any

special precautionary techniques, personal protective equipment, including arc-flash,

insulating and shielding materials, and insulated tools and test equipment.

Basic Points Of Safety

1. DANGER

• There are high voltage terminals on the electrical panel, transformer, motors,

junction boxes and other equipment.

• DO NOT touch the high voltage terminals or components under any

circumstances when the power supply is on. Make sure that all doors and

safety covers are fitted before switching the power supply on. If any door or

safety cover is to be removed, first switch off the main circuit breaker.

• DO NOT enter the machining envelope at any time that the machine is under

power. The machine should be entered only when powered off and properly

locked out to prevent accidental energizing of the machine while persons are

inside.

2. WARNING:

• Memorize the location of the emergency stop button(s), so that you can press

emergency stop immediately from any position.

HAPTER

1 - S

AFETY

• Take care not to touch any switches accidentally while the machine is in

operation.

• Under no circumstance touch any rotating work piece or tool in the spindle

with any object or hands.

• If in the slightest doubt about any procedure, consult appropriate persons or

manuals.

• Always press the emergency stop button when leaving the machine

unattended.

• If more than one person is operating the machine, do not proceed to next step

until notifying the other operator(s).

• Do not modify the machine in any way that will affect the safety of the

machine.

• Never machine flammable or explosive materials.

• Never use flammable cutting fluids.

3. CAUTION

• Do not subject the CNC control unit, the operator’s panel, or the electrical

control panel to strong voltage fluctuations.

• Do not change any machine parameter values without consulting Milltronics

service department. If it becomes necessary to change a value, first check if it

is safe to do so, then make a note of the original value so it can be reset if

necessary.

• Do not open any doors or remove any safety covers while the machine is

under operation.

• Stop all machine operations before cleaning the machine.

• Never leave the machine to run unattended.

Clothing and Personal Safety

1. DANGER

• Tie back long hair that could become entangled in machine mechanisms.

• Eye protection and hearing protection should be worn at all times when

operating the machine.

• Always use safety shoes with steel toecaps and oil resistant soles.

• Do not operate the machine while wearing loose or baggy clothes.

• Always completely fasten buttons and hooks on the arms of clothing to avoid

danger of entanglement in machine mechanisms.

• Do not operate the machine under the influence of drugs or alcohol.

• If wearing gloves to load or unload parts, be sure the machine is in

emergency stop mode.

2. WARNING

• Close all doors and covers of the CNC unit, operation panel and electrical

panel to prevent damage from water, chips, and oil.

• Emergency stop the machine and turn off the main power during electrical

storms.

• Check all safety covers regularly to make sure they are properly fitted and not

damaged.

• Always obtain assistance when handling loads beyond your ability.

• Do not adjust coolant nozzles while the machine is in operation.

• Do not remove or interfere with any machine safety devices.

• Do not wipe the work piece with a rag while the spindle is rotating or the

machine is in motion.

• Always stop the machine before removing or inspecting a tool.

• Tools and tooling can be very sharp. Take care when handling.

• Never place an object or your hand in the carousel or tool changer without

putting the machine in emergency stop.

• Never place anything between the machine spindle and tool changer.

• Never use additional clip-on or poorly secured lighting.

3. CAUTION

• Do not allow chips to accumulate during heavy cutting.

• Never use compressed air to clean the machine bed.

• Never wear gloves while operating panel switches.
