United Grinding introduces its Mikrosa Kronos S 250 centerless grinding machine, which uses angular plunging designed for corundrom and CBN grinding in high precision and mass production. The grinder features a grinding spindle mounted on maintenance-free hybrid roller bearings for peripheral speeds ranging to 150 m/sec. The company’s CBN high-speed technology reduces cycle and setup times.

The grinder is designed for plunge and through grinding of workpieces with diameters ranging from 0.059" to 1.378" (1.5 to 35 mm) with a plunge cut width up to 9.646" (245 mm). For the regulating and grinding wheels, the cross-slide system with digital drives and precision ballscrews promotes setup flexibility, dressing and grinding.

Dressing of the grinding and regulating wheels occurs via four CNC axes in the center of the workpiece plane. The machine has a thermally stable, vibration-dampening Granitan bed, which enables applications ranging from in-feed grinding in single or multiple production to through-feed and oscillation grinding.

The machine’s full enclosure complies with environmental standards, allowing for the use of different cooling media, such as emulsion or grinding oil. The wide-opening sliding doors provide user-friendly access to the grinding center, simplifying machine setups.

  • Jig Grinding On A Machining Center

    Roughing and finishing on a single machine, using a single setup, has appeal for most shops. The advantages in time savings and accuracy are obvious. Eliminating the transport of workpieces between machines, as well as the setup for those secondary operations, is a boon for throughput. Critical features that need to maintain dimensional relationships can be much more reliably produced if machined complete in one clamping.

  • Between Centers And Centerless Grinding In One Setup

    It sounds like a contradiction in terms-between centers and centerless grinding on one machine. But for some categories of workpieces, it's a viable production process that can yield machining time reductions of 45 percent over separate grinding operations.

    If one must pick a manufacturing specialty, grinding carbide might not be the first choice because it’s perceived to be very difficult. RPM Carbide Die, however, has worked the material for nearly 40 years and, as specializing seems increasingly to be the order of the day, this northern Ohio shop is in a good position to thrive.
