Rollomatic GrindSmart 630XW Tool Grinder Offers Flexibility
Rollomatic’s GrindSmart 630XW tool grinding machine can be adapted to produce a range of solid carbide boring bars and other stationary cutting tools.
Rollomatic highlights its GrindSmart 630XW machine with new capabilities for production grinding of solid carbide boring bars and other stationary cutting tools. The six‐axis tool grinding machines offer more flexibility than conventional single‐purpose grinders. With its six fully interpolating CNC axes and a six‐station wheel/nozzle changer, the machine can be 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 GrindSmart series can perform profile grinding, rake face grinding, coolant flat grinding, neck grinding and other brand-dependent features in one operation, including flipping the tool.
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. It can produce right hand/left hand and ahead/behind center with equal ease. Rake angles can be ground in two planes. Additionally, users can add quick‐change features to the grinding operations.
Compared to dedicated insert grinders, the GrindSmart six‐axis series with the wheel/nozzle changer offers more 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. Other features include mechanical and software features that are said to improve radius contour accuracy as low as 0.0001" (2 microns); a pick-and-place robot that does not damage tools after grinding; wheel and nozzle changers with six or 16 positions and wheel packs that can accommodate up to 4 wheels; linear motion control on all CNC axes; and desktop tool design software with 3D tool simulation and 3D machine animation with collision warning to increase speed and freedom in tool design. In‐process rotary dressing, or automatic sticking devices, are also available.
