GWB - Making grooves i hardened steels

Our new double clamped toolholder and vertically mounted Sumiboron grooving inserts maximise rigidity when plunge and side turning grooves in hardened steels. Suitable for a variety of groove widths from 1.5 – 6.0mm our general purpose CBN grade BN250 is recommended for grooving shafts with a continuous non interrupted surface and our coated grade BNC30G should be used for parts with interruptions such as plunging a groove in the periphery of a gear or splined component.

Sumiboron BNC300 / BN350 - CBN grade for interrupted cuts

The punishing demands on an insert turning hardened steel parts with interrupted cuts similar to gears and splines requires outstanding resistance to breakage and wear at the cutting edge. Our newly developed super tough substrate combined with a highly wear resistant TiAlN coating has met the challenge. Sumiboron BNC300 is a new grade of CBN with outstanding fracture resistance and long tool life suitable for continuous and medium interrupted cuts (interruption frequency 50%) when turning hardened steels. For heavy interrupted cuts (interruption frequency 100%) use sister grade BN350.

BN700 - CBN insert for high speed machining cast iron

For turning and milling Sumiboron grade BN700 offers many advantages including improved wear and fracture resistance when high speed machining Cast Iron. The wide range of insert styles and edge conditions expand the capability level from sharp edge for burr prevention machining, to a strong edge suitable for interrupted cutting of sintered alloys. Also suitable for exotic materials, rolls, HSS and heat resistant alloys.

SV Type - CBN insert with integral chipbreaker
	Outstanding! is the verdict on our newest CBN product - an insert with integral chipbreaker and the first of its kind ever produced. It’s purpose is excellent chip control especially in Sumiboron grade BNC200 when confronted with hard –soft turning applications like the removal of a carburised layer.

Sumiboron BNS800 solid CBN inserts

Suitable for rough machining and large depths of cut these multi corner solid PCBN inserts with increased hardness and thermal conductivity achieve accurate sizing through reduced tool wear. Used for both wet and dry machining this grade can be used for turning grey cast iron - ni-hard cast iron - alloy cast iron - chilled cast iron - hard facing alloys - hardened steels -colmonoy -stellite - metco etc

BNC80 coated CBN grade for surface finishes down to 1,6Rz
	This national award winning multi-corner insert features an ultra smooth ceramic coating to improve surface quality The dense. Sumiboron substrate enhances edge strength and wear resistance making high precision machining with surface finishes as low as 1,6 Rz readily achieveable.This grade is ideal for turning components that previously relied on precision grinding machines for final machining.

BNC150 CBN grade for high speed machining of hardened steels
	Our copper coloured Sumiboron grade BNC150 features a heat resistant substrate and special TiCN based ceramic coating for enhanced surface finish at cutting speeds Vc = 150 -300m/min. Suitable for continuous to light interrupted cuts surface finishes less than 6.3Rz are easly achieved

BNC200 predictable tool life on a wide range of applications
	Our silver coloured Sumiboron insert grade BNC200 can be used across the cutting speed band from low to high speed cutting in continuous or interrupted cut. Machining carburised surfaces at medium speeds is just one of its wide range of applications. This outstanding grade was presented with an award for best new cutting tool.

Dimple Lock Holder CBN Inserts
	This new dimple lock toolholder used in conjunction with our solid CBN inserts BNS 800 guarantees maximum rigidity of the insert when used for heavy roughing.Security at the cutting edge maximises metal removal rates and tool life

Helicalmaster award winning endmill for hardened steel

Receiving a national award for the nomination best cutting tool the Helical Master is a single blade spiral endmill which incorporates a unique anti chatter pocket design and tough CBN cutting edge of Sumiboron BN300 developed for high speed machining of hardened steels.The Helical Master is suitable for both side and end cutting applications and is capable of pocket milling,edge milling, and boring hardened tool and die steels at speeds ranging from 80 - 170 metres per minute.Invaluable to tool and diemakers the Helical Master reduces cycle times ,lead times, and machining costs manufacturing and refurbishing a range of dies and moulds.

FMU 4000 - Sumiboron face mill for high speed finishing grey cast iron.
	Suitable for finish machining the mating surface of grey cast iron componets such as engine cylinder blocks, and heads this high speed CBN cutter replaces finish grinding operations to achieve surface roughness values of Rz = 3.2 reliably and consistently at cutting speeds of Vc = 1500m/min. Widely used by engine makers and component makers throughout the world
