October 5th – 10th
Hall 14, Booth N06
The JUNKER Group takeover of ZEMA in March caused quite the stir in the grinding sector. At the EMO MILANO 2015 (October 5th – 10th), the grinding machine manufacturers will be exhibiting together for the first time in Europe: ZEMA will be demonstrating a cylindrical grinding machine for shaft grinding while JUNKER will be featuring at least three different grinding machines for grinding rolling elements, tool blanks and internal threads on ball screw nuts at its Booth N06 in Hall 14.
Grinding specialist JUNKER has radically reduced downtimes on the JUMAT 1S/30 KGi by integrating the longitudinal and radial positioning fixtures in the loading gantry. This move has enabled the grinding machine to achieve a good surface quality finish in the internal thread of ball screw nuts - with a minimal space requirement and short cycle time.
The JUPITER 125 centerless cylindrical grinding machine ensures the perfect concentric grinding of cylindrical workpieces, using either corundum or CBN depending on the application. Centerless grinding enables high metal cutting output coupled with a long grinding wheel service life, allowing for substantial production advantages in large volume processing.
The JUNKER Lean Selection speed is able to realize several grinding operations on tool blanks in a single clamping set-up. One or two high-performance grinding spindles mounted at the swivel-action wheelhead (B axis) work using the QUICKPOINT grinding method. An ingenious automation concept ensures short loading times.
At the EMO MILANO 2015, ZEMA will be demonstrating how its Numerika GH-1000 machine grinds the flange and journal of crankshafts with the utmost precision. This durable cylindrical grinding machine, with its hydrostatic X and Z axis and hydrostatically mounted grinding spindle, is ideally suited for grinding an array of workpieces for the automotive industry such as cardan or transmission shafts. In addition, the operating element of the GH-1000 is extremely simple and convenient to use.
