The JUNKER Group was present at the last EMO in Hanover, unveiling a range of innovations to the grinding industry.
At the JUNKER Group booth, visitors will be able to witness a number of live demonstrations of grinding applications, including the grinding of internal threads on ball screw nuts.

At EMO MILANO 2015 (October 5th - 10th), grinding machine manufacturers JUNKER Group and ZEMA will be exhibiting together for the first time in Europe since the JUNKER Group takeover of ZEMA earlier this year. ZEMA will be demonstrating a cylindrical grinding machine for shaft grinding and JUNKER will be featuring no fewer than three different grinding machines for grinding rolling elements, tool blanks and internal threads on ball screw nuts.
JUNKER reported that it has 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," said a company spokesperson.
The JUPITER 125 centerless cylindrical grinding machine is engineered to help ensure the perfect concentric grinding of cylindrical workpieces, using either corundum or CBN depending on the application. Centerless grinding enables high metalcutting output coupled with a long grinding wheel service life, allowing for substantial production advantages in large volume processing, the company reported.
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. The automation concept is designed to provide short loading times.
ZEMA will demonstrate how its Numerika GH-1000 machine grinds the flange and journal of crankshafts with precision. This durable cylindrical grinding machine, with its hydrostatic X- and Z-axis and hydrostatically mounted grinding spindle, is suited for grinding an array of workpieces for the automotive industry, such as cardan or transmission shafts. In addition, the company reported that the operating element of the GH-1000 is simple and convenient to use.
