NTK CUTTING TOOLS

Excellent notch and flank wear resistance when roughing gray cast iron｜Sialon ceramic

Ceramic grade with the best fracture resistance

Stable machining even in tough applications

Significantly improve productivity when replacing carbide tools with SX9

Features

The toughest ceramic grade
Excellent thermal shock and fracture resistance due to the needle-shaped particles formed during the ceramic manufacturing process

Tooling application

Case study

Machine parts
Material : FC400 Workpiece condition : with scale
Cutting speed : 2170 SFM (SX9) 270 SFM (Competitor’s CVD coated carbide)
Feed : .0059 IPR
DOC : .0789 inch
Coolant : DRY
SX9	850 pcs / corner
Competitor’s CVD coated carbide	300 pcs / corner

: SX9 achieved stable machining results in this interrupted turning operation.
By replacing the CVD coated carbide with ceramic there was a significant reduction in cutting tool costs and an increase in production.

Brake disc
Material : FC250 Workpiece condition : with scale
Cutting speed : 1500 SFM
Feed : .0157 IPR
DOC : .0787 inch
Coolant : DRY
SX9	360 pcs / corner
Whisker ceramic	264 pcs / corner

: SX9 machined at the same cutting conditions as the current whisker ceramic and resulted in a reduction in tooling cost for the customer.
