Cutters make light work of hard materials
Tool life when cutting hard materials up to 70 HRc is greatly improved, thanks to the development of a PVD-multilayer coating used on solid carbide milling cutters.
Its customers demand quality tooling from a company with a capability of delivering on time and on budget.
* Investment in CNC and tooling - Amtek has invested more than GBP 600 000 over the past 12-18 months.
A high percentage of this investment has been put into the latest machine tool technology, which has given Amtek the ability to turn or mill mould steels up to 60 HRc.

Tooling catalogue grows to over 5000 products
The latest release of the WNT catalogue has been expanded to over 1200 pages, has 18 sections and over 5000 tooling products including fine-boring, reaming, threading, milling and toolholding.
These investments complement the traditional toolmaking processes of grinding, spark erosion and wire erosion to provide optimum manufacturing capability.
Amtek's success results from its ability to respond to customer demands in a very short space of time.
The company said that this ability has been enhanced by its 'partnership' with cutting tool specialist WNT (UK).
Amtek's production manager, Mike Lawes, said: "We have worked with WNT for quite a few years.
Their ability to supply the right cutting tool at the right time has been an important factor in our success in meeting delivery targets".
* Tool vending system - the installation of WNT's Tool-O-Mat tool vending system is delivering numerous benefits to Amtek, and include the following.
* A greater control over tool usage.
* A reduction in administration.
* Considerable time savings on the shop floor due to operators having open access to the tool stocks.
Lawes said: "The freedom that Tool-o-Mat brings is a major benefit to us, because we can monitor who is using what we no longer need supervision over the issuing of cutting tools.
This frees up a considerable amount of time on the part of the management".
WNT (UK) told manufacturingtalk that the tool vending system acts as a hub for all of Amtek's rotating tool requirements and stores a wide selection of cutting tools from which all base machining strategies are evolved.
Amtek now knows that any part can be machined at any time as the correct tools will be in place.
Any tool used is replaced during the weekly visit by WNT's technical sales engineer, and Amtek receives a consolidated invoice at the end of each month, keeping accounting paperwork to a minimum.
Lawes commented: "As our tool usage changes on a weekly basis these regular visits enable us to monitor what is being used and highlights any potential issues.
The system makes my life so much easier".
* Tooling developments - most of the tooling supplied by WNT is milling-related and the two companies work together to find the best and most efficient cutting solutions.
A typical case in point is the machining of inserts and strips from 2767 toolsteel.
"The method that we have traditionally used to machine these parts has involved an indexable insert cutter," said Adriano Ruocco, one of Amtek's skilled development engineers.
He added: "We have now switched this to WNT's solid carbide MCR cutters for roughing and finishing operations".
"The difference is amazing.
We are running the 12mm diameter MCR cutters at 5300 rev/min and 1900mm/min feedrate with a 12mm depth of cut at full width.
The result is that we can now get seven inserts from each strip of material where we only achieved six before, and we have reduced the process time by three hours".
These productivity gains are further enhanced by the consumable cost savings being made since the switch to solid carbide cutters.
"To complete a set of mould inserts would require at least two changes of inserts," said Ruocco.
"With 12 inserts involved at GBP 6.00 each the cost was becoming an issue.
Now, we can complete the same work with one MCR cutter.
Not only that, because of the confidence we have in the cutter completing the machining process without failing, we can leave the machine running at the end of the shift, thus gaining even more time back".
* Unmanned machining - the ability to run unmanned with these cutters is also allowing Amtek to use its dayshift much more efficiently and machine downtime is being reduced dramatically.
MCR cutters are the third new product that has been introduced by Amtek in recent months, and this willingness to try new cutting strategies, and the ability of WNT with its technical support to deliver the product and know-how, is creating a successful partnership that will continue to deliver improvements.
