Utilization Of The Machine - Scheppach HF50 Betriebsanleitung

• Insert the clamping sleeve in the nut, or remove it.
• Firmly tighten the nut in the clamp while keep-
ing the spindle locked. Before every use of the
machine make sure that the cutting tool is firmly
clamped at the end of the spindle.
• Set the reducing piece for the opening back to its
original position.
• Adjust the fence, as required, by means of the
scale on the table.
• Connect the dust extractor unit. It is highly recom-
mended to connect a dust extractor unit (or sys-
tem) in order to keep the opening free from chips,
to cool the motor, and to facilitate the work piece
feed.
• Reconnect the machine to the power supply.
2. Setting the moulding fence
The use of the fence is a must. Every job must be
looked at separately. At every new use you must
make sure that the guards are correctly installed and
adjusted. For every new use, each pressure piece on
the fence must be newly set.
Make sure that all the bolts are firmly tightened be-
fore you start moulding.
3. Use of the table rings
The table rings must be used in order to reduce the
spacing between table and spindle to a minimum.
Before switching on the machine systematically
check the table rings supplied for their correct seat.
Check whether you have chosen the correct ring
for the corresponding cutting tool and its installation
height, in order to reduce the risk of work piece tilting
at passing the opening.
The reduction piece (table ring) must enclose the
cutter head as far as possible.
Adjustments
Adjust the number of revolutions Fig. 18
The speed adjustment of the machine has 6 stages.
• Determine the optimal number of revolutions by a
sample cut in a piece of waste material.
Note: The use of the correct number of revolutions
increases the life-span of the drill. It, also, affects
the worked surface of the work piece.
Adjust the rabbet, Fig. 19, 20
• The rabbet is to be stopped to the size of the work
piece and the milling tool.
• Loosen the 2 plastic cap screws (b) on the back
of the fence.
Set the stops and pressure devices such that
they ensure the safe guidance of the workpiece
at the input and output section of the machine.
Fig. 20
• Push the rabbet to the rear or forward of the de-
sired position. Use scale (c) on the table in order
to determine the distance and take note of the drill
centre.
• Re-tighten the 2 plastic cap screws (Fig. 19, b) on
the back to keep the fence in this position.
Adjust the rabbet for error, Fig. 19, 20
• Error from wood is the material from wood left from
the drill exiting, more thinly than the material, on
the right side.
• The left fence must be adjusted to the thinner
material. It supports the material and ensures a
more exact cut. To do this, loosen the plastic cap
screws, push the fence to the front and tighten it.
Installing and adjusting the pressure limits,
Fig. 21
The pressure limits (5) are designed so that the work
piece is held on the spot and setback is avoided.
• Drive milling cutter to the lowest position
• Insert the workpiece to be machined and press the
pressure bar onto the workpiece with light pres-
sure.
• Remove workpiece.
• Set the milling cutter to the desired height (see:
Setting the working depth).
Adjust the Cross-cutting jig, Fig. 22
• Slide horizontal along the table the cross-cutting
jig (8) in order to implement clean up error and
mitre cuts.
• In order to stop the jig at the desired angle, loosen
the locking knob of the cross-cutting jig and turn
this to the desired angle.
Tighten the locking knob of the jig (8) again.
Fig. 21
• Always make a sample cut in a piece of waste
material in order to guarantee that the attitudes
are correct.
Switching on and off, Fig. 18
Make sure that all keys and adjusting tools are well
away from the spare desk that the attitudes are in-
stalled in full and all safety covers are kept.
O - Out
I - On
This machine uses an electromagnetic switch for op-
timal security. Whenever the current is interrupted
the machine stops immediately. To restart the ma-
chine the green button must be pushed again

Utilization of the machine

• Insert an appropriate milling cutter in the tool hold-
er and secure this by tightening the tool holder nut
(Fig. 17, item 14).
• Fit and secure the cutting knives.
