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.

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.
