Compact milling cutters boast high feed
rates
A range of 90 degree milling cutters and inserts are intended for the highly productive machining of shoulders, slots and pockets, providing longer insert life.
New from Stellram is a range of 90 degree milling cutters and inserts, designated VA12, for highly productive machining of shoulders, slots and pockets Of compact design, the cutter bodies accept high precision inserts that are themselves new, having 12mm edge length and 4mm thickness for security in demanding applications

Three-in-one cutter boosts milling effectiveness
Combining three milling functions into one cutter reduces tooling inventory costs and simplifies programming when machining cast irons, steels, and ferrous and non-ferrous alloys.
Securing higher performance in milling
High productivity and security is offered by the Stellram 7702 multi-functional tooling intended for mould and die machining and milling operations in the aerospace and automotive industries.
MACH 2004 will mark their UK launch.
In one comparative test, a 20mm, two-insert Stellram cutter taking a 3mm depth of cut at 1050mm/min over a length of 80mm at a cutting speed of 200m/min produced seven components, whereas the competitive tool machined just two before the inserts needed indexing.
Another trial showed the Stellram product more than halving a cycle time and producing multiple components whereas the slower tool of the competition broke after two components had been machined.

Turning tools are dedicated to precision parts
Complex internal and external cylindrical profiles, as well as single-point threading and grooving, are generated by Stellram's wide range of Posimatic inserts and tools.
Mini tooling grooves, threads and bores
Stellram's Ultra-mini programme, consists of replaceable carbide tools that locate in a common steel shank. The tools cover application ranges for grooving, threading and boring in small parts.
3J geometry tips cut stainless steels and alloys
The new 3J geometry for stainless steels and high temperature alloys is the latest in a series of recent innovations from Stellram's research and development efforts.
Such high feed rates without undue insert wear is made possible by Stellram's insert and pocket design which permits extreme levels of rigidity combined with precise, repeatable insert location.
The results are smooth chip flow, low noise and reduced power consumption.
The VA12 system generates excellent surface finish with no mismatch between continuous passes.
Two new insert geometries have been introduced to complement the VA12 cutters.
The -721 with its polished top surface is ideal for machining aluminium alloys and non-ferrous materials.
The -46 milling geometry, on the other hand, is intended for accurately machining stainless steels and high temperature alloys.
It has a ground facet for generating smooth surface finish on the component face and is suitable for aerospace components as well as mould and die applications.
Peripheral grinding of both insert types produces a consistent edge condition and accurate radius form, leading to longer tool life.
The inserts are available in industry-standard radii of 0.8mm, 1.6mm, 2.4mm, 3.2mm, 4.0mm, 5.0mm and 6.4mm and in a variety of high performance carbide grades to suit diverse workpiece materials.
GH1: Micrograin is for aluminium alloys and other non ferrous materials; SP6564 is recommended for dry or wet machining of stainless steel; SC3025 is a new multi-layered coating offering wear- and abrasion-resistance when machining cast iron materials at high surface speeds; X500 is a grade for use in generally difficult applications and is the first choice for high temperature alloys and low cutting speeds; and MP91M is for use on steel and alloyed steels, especially if wear characteristics are more important than toughness.
An additional new product series in this Stellram programme, designed for even higher metal removal rates, is the 5315VA12.
It is based on the manufacturer's high-feed PowerMill90 cutters, but with stacked inserts for extended cutting edges.
Face milling, slotting and 0deg-side milling are possible with this versatile tool.
Weldon shank tools are available from 20 to 40mm and a 40mm shell mill is also available.
