QUALITY IN WOOD TECHNICS
WEMA News from Olbernhau
steadily increasing demand for larger and
more modern fully automated lathes with
a turned part diameter of up to 85 mm made
it clear that we needed to develop a machine
of this type. While designing the WEMA MAXIMAT
NC 85 plus NC, one of the main requirements
was the use of advanced electro-mechanical
drives together with the latest control
When integrating modern technology, a major
advantages is that all processing parameters
can be easily adjusted on the machine control
panel without having to access the work
area. The protective guards remain closed
and the machine can continue running.
All parameters such as:
motion traverse path
speed (speeds can also be changed over the
entire traverse path)
off and change over positions
therefore adjusted to the work piece within
seconds without affecting work safety.
During the new development, further improvements
were made to existing technological processes,
such as increased processing speeds, better
finished part quality and reduced tool costs.
The use of NC technology makes it possible,
for example, to pre-turn the work piece
to a suitable form using the lunette system
when feeding the timber into the system.
Standard cutters are used here.
This makes it possible to considerably shorten
the cycle times for a turned part because
the entire pre-turning step is omitted.
The contour of the turned part is created
using a CAD program and entered in the machine's
control system. This makes design changes
possible in a very short period of time.
Costly pre-turning cutters are not needed.
Many different turned part designs can be
produced without expensive form cutters,
so finishing cutters are also not needed.
This is especially beneficial for small
The design of the drilling unit is also
totally new. A two-stage processing unit,
i.e. a tool changing unit with two separate
drilling sleeves, was developed for axial
and front side processing. One sleeve is
used as previously for simple drilling tasks.
The second sleeve is controlled by a two-axis
NC control unit. Thus, it is now possible
to create contours in a drill hole using
recess cutting. This unit can also be used
for front-side processing.
The machine control system allows freely
programmable settings to be made on the
control panel for all tool supports. This
allows optimal processing that is adapted
to the specific work piece to be carried
and much shorter processing times to be
achieved, which results in a less expensive

MINIMAT 65 NC
WEMA MINIMAT 65 NC is a further development
of our approved
Automatic Small Components Lathe WEMA
The drive of both swivel heads is equipped
with electric servo axis and ball circulation
Existing MINIMAT 65 machines can
be modified to the new system MINIMAT
To work with 2 form tools is still possible
and you also can do various chippings
No more setting up of limit switches.
Positions and speed will be set up in
To each stroke work, you can put in several
positions and speeds.
By use of 2-axis NC control you can mount
a profile cutter on the front support.
This profile cutter together with the
feed can do a free definable contour.
The contour will be made on a separate
PC by Mega Cad and put into the machine.
The lathe can code profile and schedule
The advantage when working so
You save costs for tooling, because you
do not need a formtool for rough turning.
You use only 1 profile cutter for different
You do the final turning with the form
tool and reach highest quality of the
The profile cutter works directly behind
the steady, therefore you reach
Better solidity when working with long
Quicker working process at rough turning.
Saved programs can be called up quickly.
You can work with a profile cutter instead
of working with a form tool,
Or you work only partial with a form tool.
A profile cutter is cheaper than a form
Quick modification of the contour by changing
of drawing on PC
Best results by producing small series,
where a form tool would be
Excellent quality reached.
