Cancer centre benefits from XYZ VMC

The National Centre for Eye Proton Therapy, part of The Clatterbridge Cancer Centre NHS Foundation Trust’s Wirral campus, is a world leader in the treatment of rare eye cancers. The advantage of proton treatment is that the penetration depth of the 60 MeV proton beam can be controlled and only has a maximum range of 31 mm in water, making it suitable for treating any position within the eye and, in many cases, preventing the complete removal of a patient’s eye.

Patients require four treatments over four consecutive days that each take just 20 minutes. Key to the success of that treatment is a small brass component called a collimator, which is tailor-made to shape the beam to cover a specific tumour, while protecting the surrounding area. These collimators are now being machined using a new XYZ 500 LR vertical machining centre, in a cycle time that is 95% shorter than before.

Prior to treatment, a patient has the affected eye scanned to precisely identify the size and position of the tumour. Following conversion of the scan into a DXF file, a Siemens CAD reader generates tool paths for the XYZ 500 LR. From receiving the scanned data to finished part now takes between 15 and 20 minutes (against more than two hours previously), with less than seven of those minutes actual machining time.

This significant time saving has two major benefits. First, it frees-up time in the workshop to carry out other tasks, and second, on those occasions where a quick turnaround is required, it is possible to complete machining of the collimator in the time it takes the radiographer to set-up the proton beam machine and prepare the patient for treatment.

Entrepreneurialism is alive and kicking

Mills CNC, the exclusive distributor of Doosan machine tools in the UK and Ireland, has recently supplied ECAM Engineering with a new NHP 6300 horizontal machining centre.

Installed at the company’s 20,000 sq ft facility, it is the first horizontal machining centre acquired by the company in its 52-year history, as well as its first Doosan machine tool investment.

The arrival of the machine has not only increased ECAM’s machining capacity but also its production capabilities and will, over time, improve the company’s operational efficiencies and productivity levels.

Says ECAM’s managing director, Phil Arme: “We have a number of three-axis vertical machining centres at our disposal and use them to machine precision components, made from steel plate of varying thicknesses, that have previously been through our in-house steel profiling and fabrication processes. The arrival of the new NHP 6300, with its twin-pallet configuration and B-axis table, will enable us to machine these parts quicker and more efficiently. Furthermore, the new machine’s rigidity, large working envelope and BT 50 spindle technology provide significant opportunities for us to secure new contracts that involve the machining of larger and heavier components.”

The NHP 6300 supplied to ECAM includes a 37 kW/15,000 rpm BT50 spindle, a 60-tool servo-driven ATC and the latest Fanuc 31i control. Further features include roller LM guideways, a B-axis table that rotates in increments as small as 0.0001°, twin (630 mm) pallets, rapids of 60 m/min and axis travels of 1050 x 900 x 1000 mm.

Says Arme: “In the near future the machine will be used to machine steel components, often with intricate details and features, to high precision and tight tolerances.”

Three shows together in one place

Subcon 2021 (14-16 September, Birmingham NEC) is free to attend for anyone working in UK manufacturing and engineering, with visitors also gaining access to two further co-located events: The Engineer Expo and – new for 2021 – the Manufacturing Management Show (MMS). The Engineer Expo provides UK engineering professionals with the latest in-house manufacturing and design solutions alongside cutting-edge developments in advanced engineering technologies.

MMS supplies attendees with everything they need to know about running a successful manufacturing site under one roof. From maintenance and materials handling, through to continuous improvement, skills, IT and health and safety, MMS showcases a multitude of topics curated specifically for the UK’s senior manufacturing leaders.

Get set for Subcon 2021

Subcon returns to support in-person networking as the UK manufacturing sector prepares for a post-pandemic future. Next week (14-16 September), Subcon will take place at the Birmingham NEC for the 44th time, heralding a much welcome return to business events and reinforcing the value of meeting face to face for the UK’s manufacturing and engineering sectors.

Subcon is the UK’s leading manufacturing supply chain show and its return as an in-person event comes at a pivotal time as UK manufacturers of all sizes recover from the impact of Covid-19, adjust to operating outside the EU and face a myriad of challenges and opportunities. The sector’s appetite for doing business in-person could not be stronger: the show’s headline sponsors are IAMP and SCS Concept Group, while over 150 companies will exhibit, including Hoffman Group UK, Wilson Process Systems and Oldham Engineering.

How to saw pure exotic elements

The conventional user of bandsaws and circular saw machines is familiar with sawing structural steels, tool steels, stainless steels, high-strength nickel-based alloys and titanium. But relatively few have ever machined pure elements.

For Hermsdorf-based HC Starck, sawing elements is daily practice. The company is a specialist in the supply of semi-finished products and components made from refractory metals such as molybdenum, tungsten, tantalum and niobium.

The company recently sought a suitable sawing solution for the task of cutting recycled Mo-ingots or rods made of high-purity tantalum (Ta) and niobium (Nb) with a cross-section of 160 x 60 mm, as well as round material up to 207 mm diameter, which are then cut into thin sheets. Since Behringer had no experience with element sawing applications, cutting tests took place at the company’s technology centre in order to assess various machine and tool combinations, and identify a suitable sawing solution.

“Positive sawing attempts with tantalum, which has a density of around 16.6 g/cm³, were ultimately the main reason for selecting with Behringer,” explains Andreas Mund, project engineer at HC Starck. “The sawing process is very hard; the belt rumbles constantly and you can hear how difficult it is to cut tantalum. In order to achieve reasonable cutting quality, you need a very stable base frame.”

This is where the solid machine base of the HBE321A Dynamic automatic bandsaw scores points, combining a stable frame made of vibration-damping grey cast iron and a precise guide system in a portal design. Control of the saw feed comes courtesy of a precision ball screw and servo motor.
