Holroyd Precision’s CS700E tool grinding center is designed to grind high-accuracy profile forms on finish milling cutters as large as 700 mm in diameter. The machine is said to enable manufacturers of larger helical components to achieve accuracy and repeatability by giving them control of all aspects of the cutting tools they use. It produces high-accuracy profile forms on a range of materials, from high-speed steel to carbide and cermet finish machining systems.

Automatic dressing stations insure the grinding wheel’s integrity. They are equipped to condition cBN and diamond grinding wheels, while HSK-A160 arbors (as fitted to 8EX rotor milling machines) are said to enable fast wheel change-over times and enhance accuracy.

The user-friendly touchscreen programming system is designed to provide control over production accuracies. The grinding center automatically scans the tool profile during the grinding cycle. After probing, the tool profile is graphically superimposed over the theoretical profile and displayed within user-defined tolerance bands, so that cutter blades are ground within controlled limits.

The machine also sharpens multi-bladed cutters and automatically indexes cutters. The cutter is located on an HSK-A160 arbor for precise positioning on rotor millers that employ the same arbor. The maximum profile height is 120 mm.

  • Vertical Grinding Has Advantages

    In vertical grinding, the workpiece is held upright in a rotary chuck with the grinding spindle overhead. This configuration can improve roundness, facilitate single-setup processing and prolong the life of the machine. Loading and unloading may gets easier, too. Workpieces with relatively large diameters and short lengths benefit the most from vertical grinding.

  • What Is Single Point OD Grinding?

    Two enabling technologies -- superabrasive wheels and high precision servo control -- come together to provide a contour grinding process that resembles an OD turning operation. For many medium volume OD grinding applications, this method may be a means to consolidate several manufacturing steps into a single setup.
