Classic Components has built its reputation on producing parts in low volumes for vintage aircraft, where it often only has the original part to work from, and in the area of product development or bespoke manufacture where production can often be just a one-off.
While volumes may be small attention to detail remains high, with every job having full traceability, particularly for materials used in the aircraft work, all of which are certified.
Mr Duffield also documents all aspects of production with photographic evidence to ensure total accountability. Prior to founding the company in 2008 Mr Duffield spent 40 or more years working at first as a toolmaker before moving into design engineering and R&D for a multi-national business.
When he started the business his first XYZ machine was a DPM bed mill with an early variant of the ProtoTRAK control. While this machine is still in place, he decided it was time to invest in the latest variant to improve productivity.
The timing of the arrival of the latest ProtoTRAK derivative, the RX, provided the ideal opportunity. The advantages of this latest control on the RMX 3500 bed mill have helped Mr Duffield achieve significant savings both in programming and cycle times.
“The move from the old DPM control to the new RMX ProtoTRAK has been a step-change for me,” he says. “There has been 16 years of development that I am having to catch up with, but the time savings so far are mostly thanks to innovations such as Adaptive Material Removal and the ability to import DXF files.”
An example of the benefits of the DXF converter is in the production of sprockets for vintage aircraft. On his older machine Mr Duffield had to input every coordinate, which was time consuming both in terms of inputting and cross checking the data. Now, it is simply a case of importing the DXF file and pressing cycle start.
“I have gone from what could have taken a couple of hours to complete, down to a matter of minutes.”
One of the key new features of the RMX ProtoTRAK control for XYZ’s bed mills is the Adaptive Material Removal which calculates the optimum toolpath for the machining of pockets or ‘area clearance’. The savings can cut hours from cycle times and improve surface quality and tool life.
For Classic Components this feature has cut cycle time on one particular part, a development of a toilet flush unit for an upmarket bathroom manufacturer, by 50%.
“The ability of the control to create the optimum toolpath, automatically, is a big advantage. In conjunction with this, while the RMX 3500 may be similar in capacity to my old machine, the years of development that have gone into the control and the more robust construction and higher performance spindle means that I can program quicker and cut metal faster.”
As a one-man business the arrival of the RMX 3500 has made life easier for Mr Duffield, as he now knows that he has the capability to quickly turn work around for customers as the ProtoTRAK control is so straightforward, even for complex components.
“The efficiency improvements help to improve workflow. I paid for the machine outright and it only runs when needed, but that suits the business perfectly. As I only deal in one-offs and low volume, I’m not worried about payback. For me it’s about having the right equipment to do the job. And the XYZ RMX 3500 fits the bill ideally.”
