The Junker Group recently announced it will present grinding machines from Junker and Zema, in addition to air filters from LTA, at Gear Expo (Detroit, MI).

Junker’s portfolio has been expanded to include non-cylindrical grinding of camshafts for low to medium lot sizes. By using up to two high-performance grinding spindles, bearings journals and cam lobes can be rough and finish ground in a single clamping set-up. High-powered grinding spindles, in combination with proven CBN grinding technology, provide Junker’s highest removal rates and performance.

The Lean Selection cam is capable of grinding all cam lobe profiles and geometries at high speed – from concave to elliptical – and is suitable for manufacturing everything from prototypes to large production runs.

Zema will be showing its Numerika G-800. This cylindrical grinding machine with its hydrostatic X and Z axes and hydrostatic grinding spindle is designed to reach the tightest tolerances reliably and is suited for an unlimited array of work pieces. In addition, Zema also offers machines for ID/OD grinding and large shafts with diameters of up to 1 meter (40 inch) and up to 4 meters (157 inch) in length. The conversational control systems (Fanuc Based) offered by Zema are operator friendly.

LTA Lufttechnik GmbH is extending its portfolio to include a filter which has been kept deliberately simple and will be launched in the market under the name BASIC Line. LTA has developed the new entry level model to allow customers from the metalworking industry to benefit from a simple yet fully functional oil and emulsion mist filter.

The electrostatic filter is available in two versions: The smaller of the two has a single-stage filter, the larger comes with two filters in series. The filters are configured for coolant pressures of up to 40/80 bar internal cooling and a machine room of up to 6 m3. Despite the suction capacity of 1,200 m3/h, the blower uses minimal energy, as LTA installs fans exclusively in accordance with the ERP directive. The filter elements used also contribute towards simple handling: They are optically monitored and fully washable. Their compact design allows the BASIC Line filters to be mounted on all machine tools
