Danobat's CG-PG Grinders Tackle Difficult Applications
IMTS Spark: Danobat’s CG-PG range of grinding machines is said to offer near-100% machine availability while operating at cutting speeds of 80 m/sec. with conventional abrasive.
Danobat’s CG-PG range of grinding machines is said to offer near-100% machine availability while operating at cutting speeds of 80 m/sec. with conventional abrasive. The external grinding machine series is designed for complex applications with high production requirements and geometric/dimensional precision or surface quality. The machines can handle workpieces as large as 1,000 mm in diameter.
The machine range includes Danobat’s Optidress dresser, which increases the useful service life of both the grinding wheel and the diamond and reduces lost time in dressing cycles.
CG-PG grinding machines are suitable for the industrial vehicle, electric motor, energy and automotive industries but can be adapted to any field that calls for high production rates, the company says. The machines are available with automation solutions to adapt to specific needs, including a range of loading/unloading and measurement systems, traditional or CNC steady rests and automatic taper adjustments.
Achieving consistent and quality results from the centerless grinding process requires an understanding of the basic fundamentals. Most application problems associated with centerless grinding derive from a misunderstanding of the basics. This article explains why the centerless process works and how to use it most effectively in your shop.
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.
Roughing and finishing on a single machine, using a single setup, has appeal for most shops. The advantages in time savings and accuracy are obvious. Eliminating the transport of workpieces between machines, as well as the setup for those secondary operations, is a boon for throughput. Critical features that need to maintain dimensional relationships can be much more reliably produced if machined complete in one clamping.
