OD Cylindrical Grinders Enhance Positioning Accuracy
IMTS 2018: Sharp Industries will display its model OD-1524X CNC OD cylindrical grinder for toolroom or production grinding applications.
Sharp Industries will display its OD-1524X outer-diameter cylindrical grinder for toolroom or production grinding applications. The CNC grinder has an OD grinding range from 8" to 24" and a distance between centers ranging from 20" to 80". Models with traveling wheelheads can grind lengths ranging to 160". The workhead can swivel 90 degrees counterclockwise and 30 degrees clockwise for various grinding operations. The wheelhead travels on the saddle with hand-scraped and Turcite-coated V ways and flat ways. A 0.00002" linear feedback system is said to deliver high positioning accuracy and repeatability. The table travels on a cushion of oil with no metal-to-metal contact. An optional ID attachment is available for internal grinding operations.
A FANUC Oi-TC CNC and drive system delivers precise movement of the wheelhead and the table. Other optional accessories include crash control, gap control, a touch probe and an auto-sizing device.
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.
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.
If one must pick a manufacturing specialty, grinding carbide might not be the first choice because it’s perceived to be very difficult. RPM Carbide Die, however, has worked the material for nearly 40 years and, as specializing seems increasingly to be the order of the day, this northern Ohio shop is in a good position to thrive.
