The JUNKER Group

including printing rollers, electric
motor shafts and others. But its biggest benefit, Zemp notes, is its ability
to grind a crankshaft in a single setup,
saving users valuable time.
When other machines were used,
"The crank was moved from one machine to another until it was complete," he recalls. "It used to take
eight to 10 hours."
JUCRANK 8 can reduce that time to
as little as a half-hour, Zemp says. "It
doesn't have to be taken off the machine for re-measuring," he says. "All
the corrections are made with machine axis motions."
JUNKER's recent innovations
also include the JUCENTRIC 500,
a grinding machine that operates
without work piece deflection but
with strong accuracy. The machine,
Zemp notes, supports work pieces as
they are positioned and clamped between centers.
When grinding is performed, the
JUCENTRIC 500 holds pieces stiff and
straight, saving users time. "We can
grind a shaft so much faster than using
a center-less grinding approach," he
says. "A one-and-a-half-inch-diameter
shaft that is up to 20 inches in length
can be ground in 18 to 25 seconds."

International

the jucentric 500 is a grinding
machine that operates with
short cycle times and
outstanding accuracy.

kets and supply combined production
lines," Rochus Mayer, CEO of The
JUNKER Group, declares.
While production on the JUNKER side was normally used for high
speed CBN grinding, "Now we have
offerings for aluminum oxide or nonCBN grinding technologies," Zemp
says, noting that this gives JUNKER
a complete production line. "In the
past, we didn't have those products
and were only able to provide the
CBN grinding technology portion of
a production line."

Zemp praises ZEMA's hydrostatic
machines. "There is no wear and tear
[to them]," he says. "They have a very
long lifespan with the highest accuracy and reliability."
ZEMA's experience in the automotive industry makes it a good fit with
JUNKER, since its clientele includes
Bosch Auto Parts, ThyssenKrupp, Ford
Motor Co. and General Motors. "They
are all existing customers worldwide,"
Zemp says, noting that this played a
part in JUNKER's acquisition.

A Good Fit
JUNKER expanded its market share
with the recent acquisition of ZEMA,
a grinding machine manufacturer
based in Brazil. "We are the majority
owner of the company," Zemp says.
ZEMA, which was founded in 1953,
specialized in CNC grinding machines
with conventional grinding wheels for
the Brazilian market. The acquisition
will bring ZEMA's products to a worldwide customer base, as well as expand
JUNKER's expertise in the grinding
sector. "Now we can fulfill any customer needs, open up additional mar-

Based in Nordrach, Germany, LTA Lufttechnik GmbH says it is a technical leader in filtration products. "We
research, develop and manufacture filtration systems for industrial air purification," it says. "With our constantly growing portfolio of clean air innovations, we impress our clients all over the world - from machine
shops and small business to global corporations."
The company started operations in 1980 and joined The JUNKER Group 15 years later. LTA's products
include filters for oil and emulsion, welding and soldering fumes and dust. "LTA products are used primarily
with machine tools, as additions to existing machines, as central air filtration systems in production halls - or
as individual solutions - made to order," the company says.
LTA notes that its air filter systems provide the right filter for each type of particle. "They're extremely
efficient and economical with regards to both purchase price and use," it says. "They lower your operating
and energy costs, protect the environment as well as resources and ensure excellent air quality in your place
of business.
"LTA solutions ensure a healthy and productive working environment long-term: an environment in which
your employees can work, unhindered and with higher morale, assuring your company's continued success,"
LTA says.
