6.2 Spindle speeds selection
The correct spindle speed depends on
the type of machining, the cutting
diameter, the material to be machined
and the cutting tool.
These are recommended max. speeds
for a 10mm high speed steel (HSS) tool
(e.g. drill bit).
Aluminium, brass
1500 RPM
Cast iron
1000 RPM
Mild steel
800 RPM
High carbon steel
600 RPM
Stainless steel
300 RPM
If a carbide (HM) tool is used about 5
times higher speeds can be chosen.
Generally speaking, the larger in
relation the cutting diameter, the smaller
the possible RPM.
For example:
Milling mild steel with an end mill of
20mm allows a speed of
400 RPM max.
with HSS tool
2000 RPM max.
with carbide tool
7. Setup and adjustments
Warning:
Setup and adjustment work may only
be carried out after the machine is
protected against accidental starting.
Press emergency stop button!
7.1 Changing spindle speeds
Speeds may only be changed at
complete spindle standstill.
WARNING:
Changing speeds during spindle or
motor rotation will damage the gears.
Refer to the speed chart whenever
changing speeds.
7.2 Arbor replacement
Remove the draw bar cover (T, Fig 4).
Select the lowest spindle speed to keep
the spindle from turning.
Loosen the drawbar with a wrench.
Loosen the drawbar 2 to max 3 full
turns.
Tap the drawbar head with a rubber
mallet to dislodge the tool taper.
7.3 Adjusting the Depth Stop
To drill multiple holes at the same
preset depth, use the depth stop:
Turn the knob of depth stop(F, Fig 3) to
move to the desired position.
7.4 Engaging the Fine Feed Wheel
To activate the fine feed hand wheel
tighten the engagement knob (I, Fig 3).
7.5 Return Spring Adjustment
The return spring is adjusted at the
factory and should not need further
adjustment. If adjustment is necessary:
Loosen knob (X, Fig. 5) approximately
6mm.
Do not remove the spring cover (Y).
