When Warrington-based Jones Nuttall undertook a review of the overall service and support from its supply chain partners, cutting tool vendors were under the microscope. This forensic review based on a multitude of factors opened the door to UK cutting tool manufacturer, Industrial Tooling Corporation (ITC).

Located in the northwest, Jones Nuttall is a subcontract manufacturer with more than 60 employees to help it supply more than 30,000 different components to over 250 clients every year. This client list includes recognised names such as London Underground, Network Rail, Linde Group, ScotRail and Bombardier.

The machine shop is very versatile with over 12 CNC Hurco milling machines and eight CNC lathes, including models from Mazak.Producing everything from 1-offs and small batches up to runs of over 1000 from a diverse range of materials, the company utilises solid carbide and indexable tools for turning, milling, drilling and threading. When the company was witnessing indifferent service from its regular vendors, the company turned to ITC.

ITC technical sales engineer Chris Fairbrother says: “To emphasise the quality and productivity of ITC tools, we first manufactured special form tools for hydraulic components used in the fluid control industry. With supply chain issues from its previous vendor on special tools, we demonstrated our expertise by understanding the requirements of Jones Nuttall, providing technical support and then manufacturing special tools on short lead times. The tools performed exceptionally well, laying a foundation of trust and confidence in the ITC brand.”

With the relationship blossoming, Jones Nuttall incrementally introduced more ITC solid-carbide end mills to its shop floor with impressive results.

“The performance of ITC solid-carbide end mills immediately reduced tooling costs by more than 20% at Jones Nuttall,” says Fairbrother by way of example.

With over 50 years of experience machining components for the aerospace, defence, medical, electronic and automotive industries; utilising everything from two-axis lathes through to multi-pallet five-axis machining centres axis, Aylesbury-based CNF Precision Engineering could be expected to have all the expertise it needed. However, when it won a significant order to machine exhaust collector manifolds for a motorsport customer, it found itself in need of additional support.

The issue faced by CNF was the complexity of the components, which came in six variants, along with the material, 304 stainless steel.

“When we were faced with stainless steel that required extra-long tool overhangs, we knew we would need additional technical input,” says Mark Baron, CNF’sproduction manager.

Ceratizit provided a range of tooling on trial, with no commitment until successful completion of the process. Key to that success wasthe use of35 mm diameter (with 4xD flute length) KUB Pentron indexable insert drillsfor the main internal port machining, along with a selection of high-feed indexable insert milling cutters using button and square inserts, with finish milling completed using Ceratizit’s Silverline solid-carbide mills and Torus cutters.

The collaboration resulted in significant cycle time savings along with greatly improved tool life. For example, the indexable milling inserts are showing a 300% increase in tool life after testing a variety of carbide grades, eventually settling on Ceratizit’s grade for heat-resistant materials, CTCS245. A 20/30% gain in tool life was seen when switching to Silverline cutters for finish milling, when compared with an incumbent competitor cutter.

In terms of cycle time, the work undertaken with the Ceratizit Torus cutters proved to be productive, with 40-50% decrease in cycle time generated from the switch from a conventional ball-nose cutter to a Ceratizit Torus Monstermill cutter.Tool life also doubled.
