Rollomatic’s GrindSmart 630XW machine is designed to offer more flexibility in grinding indexable inserts and other stationary cutting tools than conventional, single-purpose grinders. With its six fully interpolated CNC axes, a six‐station wheel changer and wheel inclination ranging to 45 degrees, the machine supports simple adaptation for short and long runs of individual insert designs. Its design allows full interchangeability between inserts and round tools, according to the company. 

The clamping systems are designed to emulate the way inserts fit into their tool holders, increasing concentricity and accuracy. The clamping design supports indexable, non‐indexable and replaceable inserts; threading and form inserts; dog‐bone and grooving inserts; drilling, milling and ballnose tip inserts; and other non‐round tools. An electronic touch probe determines the exact location of the insert blank after clamping, allowing the software to grind the tool geometry according to the virtual centerline of the insert blank and achieve a run-out of 0.0001", according to Rollomatic. 

The company says the machine’s six- or 16-station wheel and nozzle changer offers flexibility for grinding a variety of inserts and other stationary cutting tools while maintaining the ability to change to round‐shank tools within minutes.

Additional features include an IC diameter range from 3.9 to 25.4 mm with automatic handling, linear motion control on CNC axes, desktop tool design software with 3D tool simulation and 3D machine animation with collision warning, chipbreaker grinding on the rake face, edge preparation grinding on the cutting edge, and a pick-and-place robot that protects inserts from damage after grinding. Optional features include a part flipper, an in-process rotary dressing and an automatic sticking device.


  • Double-Disc Grinding On The Move

    The double-disc grinding process is consolidating its position in automotive applications but is moving into other industries. Double-disc grinders are now easier to operate, and they have added capabilities for control flexibility, precision process control, faster changeovers, and grinding of nontraditional materials.

  • 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.

  • A Model Camshaft Grinding Process

    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.
