Putting Into Operation; Adjustments - Scheppach HF50 Original Bedienungsanleitung

7. Putting into operation

Attention: The spindle moulder has an axle that is
placed in a vertical manner onto the horizontal table.
The axle serves for the acceptance of the moulding
tools, discs and formed cutters. The spindle moulder
is used for producing friezes, simple or manifold re-
cesses, grooves, rebates, profiles and counter pro-
files on straight surfaces, etc.
With the spindle moulder, in no way cutter heads of
a larger diameter than 50 mm must be used. If larger
diameters are required, we recommend working at
several steps and the repeated adjusting with the use
of the height setting knob, or the step by step setting
of the fence.
1. Installing and changing the clamping sleeves
for top spindle moulders (Fig. 17, 14)
• Before changing the clamping sleeves, pull the
power supply plug of your machine. Select the
clamping sleeve matching the diameter of your
cutter head.
• Remove the reducing piece from the table open-
ing, Fig. 15.
• Lock the spindle with the button at the bottom of
the spindle, Fig. 17.
• Release the safety nut of the clamping sleeve us-
ing the key supplied, Fig. 16.
• 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.

8. 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.
