Rollomatic Offers Compact, Versatile 6-Axis Tool Grinder

Rollomatic’s 6-axis GrindSmart 630XW is designed for more effective production grinding of solid carbide boring bars and other stationary cutting tools compared to conventional single‐purpose grinders. With its six fully interpolating CNC axes and a 6‐station wheel/nozzle changer, the machine can be easily adapted for individual boring bar designs, both for short and long runs. The compact and versatile design allows full interchangeability between boring bars, inserts and round tools.

The company says the GrindSmart can perform a variety of functions in one operation, including flipping the tool, profile grinding and grinding the rake face, coolant flat, neck as well as other brand‐dependent features. While the machine is able to grind any large‐size boring bar, its capabilities extend to miniature turning tools, boring, threading, grooving and facing tools. Both right hand/left hand and ahead/behind center are said to be produced with equal ease. Rake angles can be ground in two planes. Quick‐change features can also be added to the grinding operations.

The GrindSmart together with the wheel/nozzle changer offer flexibility for grinding a variety of boring bars and other stationary cutting tools, while maintaining the ability to switch over to round‐shank tools within minutes. It offers radius contour accuracy due to mechanical and software features, as low as .0001” (2 microns). A pick‐and‐place robot is designed to prevent tool damage after grinding. Wheel and nozzle changers have six positions or 16 positions. Each wheel pack can accommodate up to four wheels. In‐process rotary dressing or an automatic sticking device is available. It also features linear motion control on CNC axes and desktop tool design software with 3D tool simulation and 3D machine animation with collision warning, offering a high level of functionality, speed, freedom in tool design and user‐friendliness.
