The RC series centerless grinding machines can be used for infeed grinding and thrufeed grinding to ensure accuracy, high productivity in workpieces with diameters between 1 mm and 50 mm. Automatic loading and unloading attachment is convenient to operate and reduce cost. The main features are as follows¡G
- The grinding and regulating wheel spindles are made of high quality alloy steel (SNCM-439), and treated through: normalized, tempered, carburized hardening, sub-zero treatment, and then follows the precision grinding process which can greatly enhances spindle life and stability guaranteeing deformation free performance.
- The unique hydrostatic bearings of the grinding wheel and Roller and Ball Bearing of regulating wheel can reduce the metal friction.
- The machine base is manufactured from high quality Meehanite cast iron and analyzed by advanced Finite Element Method (FEM). Along with vibration stress release, these outstanding structural features assure high strength, maximum damping capability, and longer service life.
- Total solution. Automatic grinding process design.

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 grinding, polygon grinding, camshaft grinding and crankshaft grinding etc.

KEL-VISTA – The economical universal CNC machine
KEL-VISTA – The machine offering an optimal view on the grinding process, economical, innovative in set-up and operation.
Designed for use in highly demanding tool- and mouldmaking, in machine and prototype construction, in maintenance workshops, laboratories, for economical small and medium batch production, or, in other words, wherever flexibility, precision and cost-effectiveness are indispensable.
The KEL-VISTA is designed to be a cost-effective CNC-alternative to hydraulically-controlled cylindrical grinding machines. Programming knowledge is now no longer necessary, thanks to the simple, user-friendly Kellenberger menu-based programming. The KEL-VISTA has been very compactly designed with coolant tray which is separated from the machine base, an integrated transport system and swivelling upper table. The swivelling workhead is suitable for grinding between dead centres and for chucked work, is a further example of the machine’s progressive design. The thermally-optimized bearings guarantee the highest roundness and dimensional accuracy.
