Turning Options for Every Cast Iron Application
The addition of the AC405K and the AC415K grades from Sumitomo Electric Carbide rounds out turning options for every cast iron application.
Posted: January 9, 2014
Sumitomo Electric Carbide, Inc. (Mount Prospect, IL) expanded their best-selling AC400K Series for cast iron turning to include new finishing and general purpose grades.
The addition of the AC405K and the AC415K grades rounds out turning options for every cast iron application.
The AC405K grade offers excellent wear and deformation resistance for finishing grey cast iron at continuous, high speeds. The general-purpose AC415K grade provides stable turning in a wide range of grey and ductile cast iron applications. Sumitomo’s original AC420K grade features excellent fracture resistance that produces extremely stable conditions when performing interrupted or unstable turning.
The AC400K Series utilizes the EGZ chipbreaker for general purpose grooving. This carbide cutting series features Super FF Coating and a special surface treatment that strengthens the fine Alumina layer of the insert to provide excellent reliability. This newly developed coating provides 1.5 times longer tool life than conventional tools.
A demonstration of how the AC405K grade provides a turning solution when finishing grey cast iron at high speeds. Sumitomo’s featured general purpose cast iron grade, AC415K, advances tool life in grey and ductile cast iron turning. AC420K features excellent fracture resistance that produces extremely stable conditions when executing interrupted or unstable turning. The AC400K series introduces the EGZ breaker for general purpose grooving.
New GND Grooving Tool Holders from Sumitomo are engineered to reduced chatter and eliminate vibration. Featuring high rigidity bodies and single-piece special steel construction, the GND produces less chatter and eliminates vibration. These tool holders also deliver steady performance for turning, profiling, facing and cut-off applications.
Due to precision sintering technology, the GND tool inserts offer improved tolerance of ±0.0012 in (±0.03 mm) for all grooving widths from 0.079 in to 0.250 in(2.0 to 6.0 mm).
GND tool holders also provide special chipbreakers for various machining applications. Each of the six chipbreakers serves a specific purpose from turning to profiling to facing. The GND lineup features the following chipbreakers: MG, a general feed type for turning, ML, a low feed type for multi-purpose use, GG, a general feed type for grooving, GL, a low feed type for grooving, CG, a general feed type for cut-off, and RG a general feed type for profiling.
