Optimum OPTimill MH 35G Operating Manual page 10

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.

ATTENTION!
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.

WARNING!
This machine is not intended for use in residential buildings, in which the power supply
is provided via a public low voltage supply system. In these areas it may possibly be
difficult to guarantee electromagnetic compatibility due to lead bound as well as emitted
interferences.
INFORMATION
The milling machine MH35V with frequency converter for regulating the speed are built accord-
ing to the standard EN 61800-3 class C2.
The machine MH35V is authorized for industrial and commercial use in the business and com-
mercial areas, as well as in industrial areas. The use of the machine in public supply networks
requires a different configuration and/or additional measures.
This machine MH35V installed within the domestic environment require supply authority accept-
ance for connection to the public low-voltage power supply network. Please contact your local
supply network provider.
The machine MH35V installed within the category C3 (industrial) environment do not require
connection approval.
