New Walter Cut G1221-P Monoblock Boring Bar —Walter Walter has unveiled the Walter Cut G1221-P, an innovative grooving boring bar with precision cooling, designed for recessing and internal grooving. This monoblock boring bar has two coolant holes. The first coolant hole allows the coolant to exit the insert top clamp directly to the cutting edge in the radial groove, thus providing precision cooling. The other coolant hole, at the front of the bar, can either be left open to evacuate chips out of a blind bore, or sealed off when in a through-bore to provide increased coolant to the cutting edge. Additionally, an O-ring is recessed into the bar clamping diameter to pre- vent pressure loss and provide leak free coolant supply to the cutting interface. Another advantage of the new Walter Cut G1221-P is that it can be used in both the normal and overhead position. This boring bar system holds GX09 and GX16 inserts. The insert widths go from 0.062 to 0.125 in. The system is suitable for internal grooves from Dmin = 0.63 in. and for groov- ing up to depths of 0.39 in. in all ISO material groups. New Modular Line System —Carmex Designed for internal threading and grooving applications, the new Carmex Modular Line (ML) uses a single boring bar that can be fitted with multiple adapters offering high accuracy, easy adjustment, and full repeatability. Coated with abrasive-resistant nick- el, the ML adapters can be used with all Carmex standard thread turning inserts New Products sizes 16, 22, and 27 mm. The 16 mm grooving inserts fit the MLR-L 16-32 and MLR-L 16-40 adapters. According to Jim White, national sales manager for Carmex USA, “The combination of high quality and flexi- bility in our newModular Line not only provides high performance in internal machining, deep thread generation, and grooving, it can save appreciable costs by reducing tool inventories. The boring bars and adapters are designed for use with internal high-pressure as well as conventional coolant”. Modular Fixturing for Large Parts —R&R Fixtures R&R Fixtures has introduced its modular fixturing for very large, heavy, robust parts. “The new M12 plates and components are strong and sturdy, giving the user the stability to get the job done easily and efficiently no matter how substantial the part,” said a company spokesperson. R&R Fixtures base plates are avail- able in custom and standard sizes up to 60” x 120” and are labeled on all four sides for quicker set-up and documentation
