The Finger Jointing Tool Programme

The Finger Jointing Tool
Programme
The correct tools for every
manufacturing process
All paths – one goal
A new upsurge of creativity in wood is currently taking
place. Wood, with its incomparable design diversity, its
natural character and its special atmosphere, is being rediscovered. New designs in solid wood and new interior
decorating ideas add to our living quality. Shaping wood has
a new future.
The finger joint principle is the key to this progress. It opens
up many new paths in wood engineering and for interior
decoration and outfitting. Well thought-out tool systems for
the individual production of these joints in different sizes are
an essential precondition. Leitz has made a major
contribution to the development and improvement of these
tools.
The following pages contain the most comprehensive finger
joint tool programme available from a single source. Rather
than offering and recommending a specific finger joint tool
system, Leitz has the correct tools for your company’s size,
its machinery and its manufacturing processes. All Leitz
finger joint tools have these features in common: the
highest possible product quality and profitability, tailormade for workshops as well as industrial companies.
Make your choice!

Robust finger joint cutters (composite tools) with fixed
components and individually embedded finger joint knives
reduce joint breakage to a minimum.
The body shape ensures torsional rigidity. The high-quality
HS cutting materials are treated in our own state-of-the-art
vacuum plants to ensure consistent hardness of the knives.
The shape of the body is matched to for the chip removal
process and optimised. The chips are guided directly into
the suction system and do not damage the milled joints.

Finger jointing tools with double cutting width reduce
purchasing costs for defined working widths and heights
and make repairs easier.
Cutter heads with double cutting width reduce follow-up
costs: the setting-up times are shorter and sharpening
costs are reduced by as much as 25 percent.
Fewer interfaces at tool hubs increase finger jointing
accuracy, particularly on thick woods.
If required, the tool set can be adjusted to suit intermediate
wood thicknesses by combination with finger jointing cutter
heads of conventional cutting width.

“Marathon” minifinger joint
cutter head
A new cutting material development and coating for the
profile knives of Leitz finger joint cutter heads sets new
manufacturing performance, cost reduction and quality
standards.
If you work with finger jointing machines, you will be familiar
with the potential problem: joints tear out, reducing the
accuracy of the joint. This is why you should switch now to
Leitz finger joint cutter heads. The new coating reduces
frictional resistance and resin adhesion, which has a positive
effect on the machine’s electricity consumption and
consequently on operating costs. The feed rate can also be
increased with the new knifes without any loss of processing
quality.
Feed:
Up to 24 m/min-1depending on
speed
Number of knives:
Z = 2+2; D = 160, 170, 180 mm

All the advantages at a glance:
– Exchangeable finger joint knives
– Finger joint cutter head with offset knives that are parallel
to the axis and can be re-sharpened
– Straight clearance flank grinding
– Highly accurate bore, hub and profile knives ensure
extremely strong finger joint connections up to the final
sharpening
– Finger joint knives can be replaced if a cutter breaks
– Highly economical, with a service life 4 times longer than
uncoated HS finger joint knives
– Reduced grinding loss due to less cutting edge abrasion

shoulder cutter: a flexible and versatile
solution for new businesses
HW minifinger joint disc cutter
WF 624-2
Finger joint mills (tool combination) with fixed cutters can be
used for finger lengths of 10/11 mm and also for special
finger lengths on machines with cross-cutting unit.
The cutter width corresponds to the finger joint pitch minus
the hub thickness. A flexible tool set arrangement with and
without shoulder cutter, shoulder finger joints (butt joint) in
the centre or in the finger joint base is possible up to 150
mm.
These disc cutters can be used for hard or soft wood. The
range includes tools with different diameters, finger joint
pitches and numbers of knives. Finger jointing tools can be
used on flat finger jointing machines (single- and doublesided) or on double end profilers. The spiral-shaped cutter
arrangement minimises motor power consumption.

cutters are combined as a tool set and mounted on screw
bushings (see illustration). When working on wood thicker
than 80 mm, we recommend clamping the finger joint tools
to the screw bushing with a hydro nut.

TurboHawk minifinger joint cutter head
HM 620-2-05
TurboHawk, the ultimate tool for flat
finger joints
This is a tool body for finger joint profiles with finger lengths
of 10/11 mm; 9.52 mm (3/8") and 6.35 mm (1/4"). The preassembled cutter sets can be installed and accurately
positioned for wood thicknesses of up to 50 mm. Whenever
a product change-over becomes necessary, tools can be
installed and are ready for use very quickly.
Economical
The knives can be re-sharpened more than 200 times.
Cutter breakage is almost impossible due to the special
cutter fixture.
The re-sharpenable tools have a constant diameter and
profile. For this reason, the machine does not have to be set
up again after tool repair. Machine standstill times are
therefore reduced to a minimum.
