LIGNA REVIEW
Vollmer at Ligna
VOLLMER welcomed the international trade press, including PW&SS,
to its extensive stands at Ligna 2011, spread over two halls, on the
middle day of the show, demonstrating processes as diverse as the
grinding of circular saw blades, automated polishing of PCD tools,
an automatic benching centre RC 110 for machining band saw blades
and innovative software packages.
The QM eco select is equipped with five simultaneously controlled CNC
axes and measures and erodes in one single clamping. It is designed to
process tools with PCD-tipped cutting edges with ultimate efficiency and
best surface finish quality. The individually selectable software packages
are said to make the machine especially suitable for beginners.
The standard version of the QM eco select includes a basic software
package, which can be extended with up to three software add-ons. The
hogger package was, for example, designed for processing radius hoggers
in path operation, or profile hoggers with plug-in method. The profile
package includes a four-path program, and works with a peripheral
electrode. The saw blade package covers the complete top and face processing
of all common saw blade tooth geometries. Additional software
packages can be installed at any time.
While one work piece is processed, the parameter of yet another work
piece can be entered in the measuring and eroding program. The piece
is clamped into the machine, and the program for fully automatic processing
is started. Within each processing program, up to four different
eroding steps with individual parameters can be applied: coarse roughing,
roughing, finishing and fine finishing.
The QXD 200/400 offers fully automatic polishing of PCD cutting tips.
Formerly, this application had to be applied manually, whereas now the
machine measures the surfaces of the PCD tips by auto-touch immediately
after eroding and subsequently polishes
them. Different types of tools such as
face milling cutters, groove cutters, groove
drill cutters and other types of cutting tools
can be processed in unmanned operation
and large batches. The polishing process improves
significantly the surface quality of
the PCD tips, and therefore leads to prolonged
operating lifetimes of the cutting
tools. This is because the previously eroded
tips receive an ultra fine surface finish with
roughness results of a few micrometres and
become more resistant to wear and tear, depending
on the type of use.
The CP 200 and CPF 200 new grinding machines
are equipped with four CNC axes,
multiprocessor technology and integrated
software programs. The CP 200 with CNC
axes and multiprocessor technology is designed for top and face grinding
of TC-tipped circular saw blades with a diameter of 80-650 mm. All
common tooth geometries of the wood and aluminium processing industries
are integrated and can be run in one single process cycle. Saw
blades with cutting tips situated in axial angles can also be processed in
one cycle. The CPF 200 is designed for side grinding. The user can choose
between five integrated grinding programs and machine saws with
grouped teeth in one cycle. Another option is oscillation grinding, where
the operator can determine the number and infeed of the grinding
strokes. The lateral relief angle can be introduced either as absolute value
or as angle. Positive and negative hook clearances, which are common
amongst scoring saw blades, can be machined with no problem.
Vollmer’s RC 110 is considered especially suitable for the complete and
fully automatic processing of band saw blades: straightening, levelling
and tensioning in one single clamping.
Thanks to the new measuring unit, the enhanced
benching centre RC 110 achieves
even more precise results when processing
band saw blades. The application is now easier
and more accurate, especially the band
saw blade run-out, and operating lifetime
can therefore be significantly improved.
Vollmer can also offer all the services required
for the lifetime of a machine: from
consulting and financing, through initial machine
set-up, machine operator training,
maintenance and service work, as well as
software upgrades.

HEALTH & SAFETY
A breath of fresh air from Fercell COSHH/LEV services
THE LEGAL BIT: The quality of compressed air to an aspirator is vital in terms of Health &
Safety. The British Standard for BS EN12021 defines the maximum contaminant para -
meters for breathing air and states, “A competent person should test the quality of the air
supplied for breathing apparatus at least once every three months. More frequent tests
should be conducted if contamination is foreseeable within this three month period.”
The Nice Bit: With more than 35 years’ industry experience delivering air control, air extraction
and dust and fume filtration products and services, Fercell Engineering could be regarded
as specialists in the design, manufacture, supply and installation of turnkey systems. The company’s
engineers hold both P601 (commissioning and thorough examination and testing of
LEV Systems) and hygienist qualifications to ensure a professional COSHH LEV testing and maintenance
service, in compliance with current legislation, thereby ensuring a safe working environment
for employees. The company’s COSHH LEV services are competitive priced,
administered by proficient, competent engineers and tailored to best suit customers’ needs.
Much of Fercell’s business comes through referrals. Fercell adopts a friendly, straightforward,
no pressure approach, quoting competitive prices and ultimately delivering concise,
fair, comprehensive written reports, where necessary including sensible recommendations.
