This image shows the interior of C & B Machinery’s DG-2H double-disc grinder designed for rigid, high-production applications. The grinder is available with grinding wheels ranging from 584 to 1,067 mm (23 to 42 inches) in diameter.
Amada’s Winstar SP (V-spec) form grinder features a CCD camera and software that can measure shapes directly on the machine. The software automatically calculates compensation values based on a target profile and the measured workpiece, the company says.
The model S272V belt grinder from Kalamazoo Industries offers a 2 × 72-inch belt and a multi-position paten capable of rotating 360 degrees. The machine is intended for grinding, shaping and contouring for die casting applications.
The grains on 3M Abrasive Systems’ 3M Cubitron II gear grinding wheels continuously fracture as they wear, forming sharp points and edges for consistent performance.
Holroyd Precision offers its WG series of grinding stations designed for worm gear shaft production. Depending on the model, the machines are capable of grinding worm shafts ranging from 3 to 500 mm in diameter with thread lengths ranging to 1,600 mm.
Rush Machinery’s drill and tool grinders enable resharpening HSS and carbide drill points, taps, reamers, end mills, and more. Manual benchtop and floor models with automatic in-feed are available.
The Suprema 100M cylindrical grinding machine from Jones and Shipman (a subsidiary of Hardinge) offers a 160-mm center height and 100-kg weight capacity. Its larger-diameter wheels are said to reduce the number of dresses needed during grinding cycles.
The work chamber of Gleason’s Phoenix 280G bevel gear-grinding machine lacks rails, pipes and other features that can collect swarf, helping to keep it clean and reduce maintenance. The wheel dresser, for example, telescopes out of the work chamber to reduce the wiring and piping typically found there, the company says.

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.
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.
