Matthew Boyt, managing director of CR Engineering in Wotton Underwood near Aylesbury bought the company from his previous employer in 2020 and since then has had a programme of investment in XYZ Machine Tools to keep up with demand.Originally formed in 1947, CR Engineering started off with watchmaking but now makes precision components for a wide range of applications including X-ray machines, bottle filling machines, bath lifts and specialist laser machinery.
“Before I bought the company and worked as an employee, Colin Rapsey, the previous owner, had already invested in XYZ Machine Tools, installing the first machine in 1998,” explains Boyt.“All the employees liked and were familiar with the ProtoTRAK controls and, the machines themselves had proved their reliability and return on investment, so it was an easy decision to continue working with XYZ Machine Tools as the business has grown.”
For turning, the company currently has three XYZ machines: a CT65 HD lathe with 66 mm capacity Hydrafeed bar-feed system, Siemens 828D ShopTurn touchscreen control and tool setting probe; a ProTurn RLX425 gap-bed lathe with 480 mm swing and 2500 rpm spindle (both purchased in July 2022); and a ProTurn SLX 355 with 1000 mm between centres which came with the company purchase.
For milling, the company’s XYZ machines include: a KMX 2000 turret mill with 762 x 380mm travel; an RMX 3500 bed mill with ProtoTRAK RMX control, 787 x 508 x 508mm travel and 5000 rpm spindle; and an RMX 5000 with ProtoTRAK RMX control, 1524 x 596 x 584mm travel and 7.5 hp programmable variable speed head. The latest acquisition is an XYZ 1100 HD vertical machining centre.
“This is my dream machine, and it would not fit in our previous factory,” says Boyt.“We moved to our new premises in August 2022, expanding our operation to 3600 sq ft. Purchasing this machine was one of the first things I did. We can fit three vices on the bed, so typically we can machine multi sided parts in one set-up, simply moving and turning them from one vice to the next to produce a finished part straight off one machine. Not only does this save on handling, it also improves accuracy and quality.”
The XYZ 1100 HD comes with a 33 hp, 10,000 rpm spindle, a 1200 x 600 mmtable and a Siemens 828D ShopMill 15″ touchscreen control or a Heidenhain TNC 620 control.
CR Engineering’s move to its new factory was orchestrated by XYZ’s haulage, moving the all the machinery and installing the new RMX 5000 in the space of one and a half days.
Says Boyt: “To recommission all the machines and install the new RMX 5000 so quickly minimised our downtime and was an impressive feat. Even better, the RMX 5000 paid for itself with the first job we put on it.”
The company specialises in small batch quantities of between 2 and 200 parts in a wide range of materials that include stainless steel, mild steel, aluminium, brass, acetel and nylon. Programming takes placeat the machine control, taking advantage of the easy ProtoTRAK, ShopMill and ShopTurn interactive conversational programming.
“We find this works well for the small batch quantities we make,” reports Boyt.“However, a really useful feature is the TRAKing on all the XYZ machines, which gives us the ability to run forwards and backwards through a program by turning the hand-wheel, quickly proving it out before hitting the start button, avoiding scrap and expensive damage to the machine.”
The investment in new machinery has impressed CR Engineering’s customers and it is seeing a growth in orders thanks to the large-capacity machines it has where some parts are up to 2.5m long. No one locally has the capability to machine components of this size. Similarly, the company is reaping the benefits of reshoring where customers are re-evaluating security of supply. CR Engineering is BS EN 9001:2008 registered, so accuracy, repeatability, traceability and on-time delivery are important parts of its ethos.
CR Engineering has nearly 70 years of experience in producing quality precision components for a wide variety of industries. The knowledge and skill within the company offers a refreshing blend between traditional engineering and modern current practice, allowing the customer to have confidence that both quality and service are available to them, as indeed it continues to be with many long term current customers. However, with Boyt now at the helm, the company is enjoying a new dawn based on investment in both capital equipment and staff.
“We now have 10 employees, adding a further four since I took over in 2020,” concludes Boyt.“Our staff are highly motivated and prepared to go the extra mile for our customers. Working with XYZ Machine Tools gives us the confidence that we can achieve our aims. The machines are well built and reliable, and the service is excellent. We hardly ever have any trouble with the machines and, if we do, it’s fixed the next day. We’ve found the machines to be very good value for money and will continue investing with XYZ Machine Tools as our business grows.”
