INFORMATION
Use a water-soluble and non-pollutant emulsion as a cooling agent.This can be acquired from
authorised distributors.
Make sure that the cooling agent is properly retrieved. Respect the environment when dispo-
sing of any lubricants and coolants. Follow the manufacturer’s disposal instructions.
4.6
Clamping the workpieces
CAUTION!
Injury by flying off parts.
The workpiece is always to be fixed by a machine vice, jaw chuck or by another
appropriate clamping tool such as for the clamping claws.
4.7
Feed
with the hand cranks on the milling table.
Note the different forces acting during synchronous milling and conventional milling on the spin-
dles of the milling table. The cutting forces during synchronous milling tend to be that the tool
will move into the material.
Conventional milling is always to be preferred over synchronous milling.
Only with recirculating ball screws can the use of synchronous milling be undertaken sensibly.
The forces and backlash occurring in the spindle nuts leads to "chatter marks" on the surface of
the work piece in synchronous milling.
In conventional milling, the work piece moves with the hand cranks on the milling table opposite
to the direction of rotation of the miller.
In synchronous milling, the work piece moves with the hand cranks on the milling table in the
direction of rotation of the miller. A smoother surface is obtained compared with conventional
milling. So, machining in synchronous milling should only be used for finishing.
4.8
Swivelling the drill-mill head
The drill-mill head may be swivelled 90° to the right
and to the left.
CAUTION!
The drill head may tilt to the right or to the left on
its own after loosening a screw. Proceed with
extreme caution when loosening the clamping
joints.
