Ceramic Cutting Tools Boost Productivity with HRSAs
Seco Tools now offers Secomax CS300 ceramic inserts and cutter bodies to boost productivity in milling and turning operations with heavy interrupted cuts on nickel-based HRSAs.
Seco Tools now offers Secomax CS300 ceramic inserts and cutter bodies to boost productivity in milling and turning operations with heavy interrupted cuts on nickel-based, heat-resistant superalloys (HRSAs). The new cutters increase productivity by up to eight times over standard carbide milling, according to the company, and are designed for machining a range of components for aerospace and power generation turbine segments.
CS300 inserts use SiAlON-type ceramics that offer high notch wear resistance, toughness and thermal shock resistance. The inserts provide optimum flank wear resistance at higher cutting speeds ranging from 1,970 to 3,940 feet per min., enabling feeds from 0.002" to 0.006" (0.05 to 0.15 mm) per tooth. Combined, these attributes reduce machining cost per workpiece, increase output and lower energy consumption.The new R220.26 and R217.26 cutter bodies are hardened and nickel-coated for high reliability, reduced chip friction and better resistance to high temperatures. Wedge clamps provide more secure insert locking and feature internal air coolant channels that ensure optimum chip evacuation and heat control. The metric range includes cutter bodies with RP 1204 inserts for facing and pocketing in diameters ranging from 32 to 50 mm. Cutters with RN 1207 and RN 1204 inserts for facing are available in diameters from 32 to 125 mm. The imperial range includes diameters 2.0", 2.5" and 3.0".
To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.
Consider these alternatives when conventional drilling can't do the job.
The right choices in tooling and technique can optimize the thread turning process.
