about the rugged conditions turned out to be a decisive factor
in favour of Blum-Novotest’s Mini-Micro-Nano laser system.
“Blum simply told us that a rugged environment was what
their lasers were built for,” Kardas says. “They’re made to run
in conditions where coolant is dripping off the spindle.” An
air jet on the front of the laser keeps coolant away from the
lens, which is also equipped with a shutter that opens during
measurement but otherwise remains closed.
As part of the purchase package, Blum handled the
installation of the laser tool measuring system on the Doosan
machines, finishing the work in May 2016. With the lasers
in place, the procedure is now simpler, faster and, of course,
much more highly automated. “The operator loads the tool
into the spindle and hits cycle start. We have all the data in
the program so when you do a tool change, the laser turns
on, measures the diameter, the length, and the run out on the
tool,” Kardas says. For drills, the run out is critical, especially
with reamers; if the spin isn’t straight, the hole will wind up
oversized. “With the lasers in place we don’t have to hold
anyone accountable other than for putting the tools in the
holders correctly,” Kardas says. “This system automatically
puts the input right into the machine. No more operators
pressing buttons based on what they thought they read off a
tag. It’s improved efficiency. The change is dramatic.” SMT

CORPORATE TECHNICAL CENTRE
Precision Resource’s technical centre in Cambridge,
on, focuses on designing and building tools for all
of the company’s locations. the tooling know-how
located here provides a competitive edge for the
fineblanking process, thanks to major investments in
the centre’s equipment and human capital. kardas
says that the state-of-the-art equipment used here
helps PR develop continually tighter tolerances in the
tools it builds.
he also says that the company’s global
presence has allowed it to transfer and leverage its
know-how across multiple continents, positioning
it as a supplier of choice for its customer. the
company is now expanding to focus on highly
complex parts and solutions, using its in-house
engineering expertise to solve manufacturing
problems in the area of metal forming.
the centre includes Makino S56 vertical machining
centres. aside from one floor demo model that
Precision Resource purchased, these were all acquired
with the blum laser system already installed.

presses is the longest line in
