this is important). For mills, do not forget to use the retractable guard at the back of the
table. For lathes, always close the front door when cutting, regardless of mode.
Notes on the E-stop and Guard critical safety functions:
•
E-stop:
•
This is provided by a safety rated, hard-wired E-stop system controlled by the E-stop
button on the pendant or table guard/apron panel. When the machine is E-stopped, the
axes are disabled and the spindle is put into a Safe Torque Off mode.
•
Releasing the E-stop button and pressing the Reset button, will always take the machine
out of the hardware E-stop condition (unless there is a fault with the safety circuits).
However, the machine may still be disabled because of the current machine mode, or on
the results of software safety checks undertaken by the control (fault 0055). This an
“NC Not ready” state; and should not be confused with the
hardware E-stop condition.
•
If you wish to leave the machine in a hardware E-stop condition, for example, when
leaving the machine unattended, always press in, and leave pressed in, one of the E-
stop buttons. Do not twist to release the E-stop button until you are ready to make the
machine live again.
•
Spindle Guards (table guards for mills or chuck/belt door guards for lathes):
•
When the spindle guards are opened, the spindle control system actively drives the
spindle to a stop very quickly, but the spindle remains powered. After a short delay, the
spindle is put into a Safe Torque Off mode, where the spindle is now completely safe.
On mills, this time delay coincides with the spindle air brake being applied.
•
Therefore, DO NOT touch the spindle until the spindle is in the Safe Torque Off Mode,
i.e. the mill air brake has engaged (which occurs approximately 3 seconds after the door
guards are opened) or a few seconds after the lathe chuck has come to a stop.
•
Note, if the spindle guards are closed again at about the same time as the delay expires,
due to small differences in each of the dual channel safety circuits, it is possible for the
safety circuit to lock out and then the spindle cannot be run. In this case, simply open
the guards again and wait about 10 seconds before closing.
When operating this machine, always observe the following safety precautions
•
Do not operate this machine without knowing the function of every control key, button, knob,
or handle.
•
Always wear the appropriate personal protective equipment, including safety glasses and
safety shoes.
•
Do not wear loose fitting gloves whilst operating this machine as they could easily get caught
in moving parts.
•
Never wear rings, watches, long sleeves, neckties, jewelry, or other loose items when
operating the machine.
•
Keep your hair away from moving parts. Wear adequate safety head gear.
•
Never operate any machine tool after consuming alcoholic beverages, or taking strong
medications, or while using non-prescription drugs.
•
Carry out a COSHH risk assessment and use the correct protection equipment, e.g. barrier
cream/latex gloves, to prevent harm from items such as cutting fluid, lubrication oil and other
substances used on the machine.
•
Do not use compressed air to remove swarf or clean the machine. This can damage the
slideway seals and create coolant mist which can be harmful. XYZ recommend the use of
BioConcept cutting fluids which do not present a risk to the respiratory tract.
•
Always ensure the appropriate guarding is in place for the machinery operation being
undertaken. Never reach around a guard to gain access to the part, tool, or fixture.
•
Observe and understand the warning and safety information labels affixed to this machine.
•
Do not attempt to tamper with or override any guarding/safety device fitted to the machine.
•
Stop the machine spindle, open the table/ or chuck guards and take the CNC control out of
an active mode (DRO, RUN, TOOL SETUP):
o
Before changing tools.
o
Before changing parts.
