QUICKPOINT's great advantage: This technology can be used for a wide range of applications in combination and combines this with extremely high productivity. Compared with conventional OD grinding - especially when grinding Tungsten Carbide - the QUICKPOINT method can
increase productivity by up to 600%!
QUICKPOINT grinding is a high-speed “peel grinding” process based on point contact between grinding wheel and workpiece. The QUICKPOINT process requires highly
wear resistant CBN or diamond grinding wheels which are typically only a couple of millimeters wide. Tilting the abrasive wheel to the horizontal workpiece axis creates a
relief angle that reduces the contact zone between abrasive wheel and workpiece from a contact line to a contact point.

Ultra GU-3250CNC is the ultra design for both eccentric and non-round grinding. The Granite mineral-casting machine base with box-style hydrostatic slideway allows no metal contact and higher feedrates, resulting in long machine life and excellent damping behavior to increase ground parts quality. The favorable thermal behavior of Granite extensively compensate for temporary temperature fluctuations, resulting in high dimension accuracy at all times. FANUC 31i controller can deal with in-feed movement in nanometer. The angle encoder for C-axis can give feedback to the controller, allowing precise control for non-round grinding.
Applications include eccentric, polygon, camshaft, and crankshaft parts grinding, etc

KEL-VERA
The on-going consequent development has led to the introduction of this extremely compact machine which is based on a visionary modular concept. The new design of the hydrostatic guideways is meeting even the extremest requirements on universal as well as on production grinding.
Building-up on their experience of more than 15 years with hydrostatic guideways KELLENBERGER is launching a completely new range of machines. The objective rigorously striven for had been to develop a compact machine which can be used for the grinding of any kind of components with a length of up to 400 mm.
The concept is based on platforms for the table slide and wheelhead supports, and also for applications where the table slide is the direct starting basis. The new machine models are offered in their standard configuration. Application- and customers-specific versions, however, are also available. The new very rigid hydrostatic guideways provide the basis for higher performance and dynamics in the X- and Z-axes. Further, the productivity and precision on unround grinding are significantly enhanced.
As an option automatic loading and unloading systems, integrated into the machines, can also be delivered.
