We see from your search that you're looking for information on the term "Metal Removal Rate",
and we have a large number of manufacturers' news releases and technical articles here on Manufacturingtalk which will be of interest.
Let me be your guide.
Start with
the news release Mill-turn centres increase metal removal rate from
Kingsbury Machine Tools, which we summarised at the time by saying "German CNC lathe builder has redesigned its mill-turn centres that are over twice as rigid as earlier models, allowing an increased depth of cut to be taken to maximise metal
removal rate".
A couple of weeks before,
we featured the news release Machine tools take the lead - for now from
Mike Page - editor's feature articles: "At one time, tooling development tended to be a year or so ahead of machine tool development, lately the trend went the other way, though toolmakers are now more than catching up, writes Mike Page".
In November 2007, we covered the news from Mitsubishi Carbide
concerning its Multi-functional AXD7000 series
- take a look at Aluminium alloys milled at high removal rates
which says: "Multi-functional cutters offer metal removal rates in aluminium alloys of up to 10,000 litre/min owing to rigid tool body, ultra secure insert clamping and the geometry of carbide inserts".
Take a look also at the news release from Sandvik Coromant UK, High speed milling insert ups productivity 30%,
as well as Dedicated VIPER grinding centre is 10% faster from NCMT,
and Solid carbide milling cutters up metal removal from WNT (UK).
