Possible Dangers Posed By The Milling Machine - Optimum OPTImill MH 22V Operating Manual

WARNING!
Risk of injury caused by flying workpieces.

Clamp the workpiece in the machine vice. Make sure that the workpiece is firmly clamped in
the machine vice and that the machine vice is firmly clamped onto the machine table.
Use cooling and lubricating agents to increase the durability of the tool and to improve the

surface quality.
Clamp the cutting tools and workpieces on clean clamping surfaces.

Sufficiently lubricate the machine.

Set the bearing clearance and guides correctly.

Recommendations:
Insert the drill in a way that it is positioned exactly between the three clamping jaws of the

drill chuck.
Clamp end mills (or shank cutters) in a collet chuck using the corresponding collets.

Clamp end face mills using shell end mill arbors.

When drilling, make sure that
the suitable speed is set depending on the diameter of the drill,

the pressure must only be such that the drill can cut without load,

if there is too much pressure, the drill will wear quickly and may even break or jam in the

borehole. If the drill jams, immediately stop the main motor by pressing the emergency stop
button,
use commercial cooling/lubricating agents for hard materials, e.g. steel and

generally always back the spindle out of the workpiece while it is still turning.

CAUTION !
Do not use the drill chuck as a milling tool. Never clamp a milling cutter into a drill
chuck. Use a collet chuck and appropriate collets for end mills.
When milling, ensure that
the right cutting speed is selected;

for workpieces with normal strength values, e.g. steel, 18-22 m/min,

for workpieces with high strength values, 10-14 m/min,

the pressure is selected so that the cutting speed remains constant,

normal trade coolants/lubricants are used for hard materials.


Possible dangers posed by the milling machine

The milling machine was built using state-of-the-art technology.
Nevertheless, there is a residual risk, as the milling machine operates with
high speeds,

circulating parts and tools and

electrical voltage and currents.

We have used design and safety engineering to minimize the health risk to personnel resulting
from these hazards.
If the milling machine is used and maintained by personnel who are not duly qualified, there
may be a risk resulting from its incorrect or unsuitable maintenance.
INFORMATION
Everyone involved in the assembly, commissioning, operation and maintenance must
be duly qualified,

and strictly follow these operating instructions.

Always disconnect the milling machine from the electrical power supply before performing
cleaning or maintenance tasks.
