Advances in Cutting, Sawing & Sawblades
124 S eptember 2009 ›
BY using improved MMKS-systems, high
additive lubricants, cooling-nozzles, blades
with specially adapted cutting geometrics
and modern machines, it is now possible
to achieve 50,000 pieces of steel and
30,000 pieces of stainless steel compared
to former tool lives, Sat Semer Anlagen-
Technik claims.
This increase is possible by improvement
and higher precisions of the machines,
higher feed, the use of high-performance
lubricant and the use of cooling-nozzles.
One case study using a fully automatic
sawing-machine – the MMKS-system
SAT P-202 – a SETOL high-performance
lubricant and cooling-nozzle, achieved the
following results:
• High-tensile steel S460MC with a tensile
strength of 670N/mm²
• Tube 30x2x1,700mm
• Tool life ca. 6,000 by 1,027 per hour
• The 100% lubrication and cooling provide
a performance increase of stress on the
tooth up to > 0.12mm/tooth.
100% lubrication results in steel tube
40x1.5mm at 50,000 cuts consumption
uses only 400ml SETOL high-performance
lubricant.
The combination of MMKS with high-
additive lubricants and cooling-nozzles is
used serially for HM-sawing-blades with
diameter up to 1,600mm.
The company says the use of MMKS-
systems and the high-performance
lubricants results in:
• Increase in tool life
• High cutting performance
• Less burr cuts
• Non-ferrous heavy metal can be
continued
• Processing by using special lubricants
(no degreasing before soldering is now
required)
• Savings by reduction of washing process
• The tubes can be brushed, measured
and discharged into the carrier after
cutting
• Savings in removal of emulsion and
cleaning cost for polluted workplaces
and machine parts
• Using non-water-miscible-oil the elixir
water is preserved.

Increasing tool life using cooling
Cutting line
fitted with
double rollers
 The MMKS-systems cooling nozzle
 Maco's VK 370 circular sawing machine
A CUTTING line from Maco, Italy, features a
tube feeding system made from two rollers
provided with a device for the trim-cut – with
adjustable dimension. With accelerating and
decelerating ramps, the head cut-off length
can be changed and memorised.
A logic control system with a touch-screen
user interface allows different programs to
be entered and stored (ramps and feeding
speeds, number of pieces and bars). It also
includes alarm messages and an electronic
disk protection device for added security.
The workpiece length is determined by a
bar stop that can be positioned manually.
The bar stop back feeding device and
workpiece unloading are standard, and the
workpiece discharging length is variable at
the customer’s request.
