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.

Optimizing a camshaft lobe grinding cycle has traditionally been based less on science and more on educated guesswork and numerous test grinds. Now, computer thermal modeling software can predict areas where lobe burning is likely to occur, in order to determine the fastest possible work speed that won't thermally damage lobes and greatly reduce the number of requisite test grinds.
