Precision engineering has always been about accuracy, consistency and efficiency – and as component complexity increases, so do the demands of manufacturing capability and our customers’ requirements. To meet these evolving needs, Bronte Precision Engineering in West Yorkshire has invested in the DN Solutions’ Mynx 6500/50 II, supplied by Mills CNC, which strengthens our capacity for complex machining while also improving repeatability and process efficiency.
After its installation, we’ve been able to increase our in-house milling machining – one of our core capabilities – improving versatility and allowing us to machine a wider range of materials.
The new Mynx 6500/50 II is equipped with the Fanuc 0iMP and a gearbox-driven, high-torque BT50 spindle, which delivers faster machining and improved overall performance across demanding applications.
Why upgrading our machining capability was essential
The new Mynx 6500/50 II replaces a Daewoo Mynx 540 machining centre that had been in service at Bronte Precision Engineering for over 20 years. During this time, the machine produced complex, high-precision components for customers across the oil and gas, power generation, marine, rail and electric vehicle (EV) sectors.
While the Mynx 540 served as a reliable and rigid box-guideway machine, its BT40, belt-driven spindle increasingly limited productivity when machining harder and more demanding materials such as Inconel, duplex stainless steels and cast iron.
“The machine was holding us back,” Steven Haigh, Director at B&B and Bronte Precision Engineering, said, “Cycle times were overly long, and our machining processes had to be built around its limitations. To improve performance, we needed a new, high-performance machining centre.”
Finding the right machining centre for our facility
In order to combat these challenges, we defined detailed requirements focusing on rigidity, torque, table capacity, advanced control technology and in-process measurement. After evaluating several options, the Mynx 6500/50 II stood out for its rigidity, powerful BT 50 spindle and level of technical support offered by Mills CNC. Each of these elements have enabled us to significantly improve productivity.
Performance impact
Since its installation, the Mynx 6500/50 II has proven to be a worthwhile investment by already speeding up processing times by up to 50%.
The investment was also featured by MTDCNC, which detailed the technical capabilities of the Mynx 6500/50 II and its impact on Bronte Precision Engineering’s machining performance.
“The Mynx 6500/50 II is a powerful, accurate and flexible machining centre that has proven its worth within weeks. The machine’s rigidity and powerful BT 50 spindle have enabled us to significantly improve productivity and part cycle times,” said Haigh.
Our investment in the Mynx 6500/50 II represents a significant step in the ongoing development of Bronte Precision Engineering. By continually strengthening our machining capabilities, improving efficiency and cycle times and expanding the range of materials we can process in-house, the new machine supports our long-term commitment to continuous improvement and advanced machining – both at Bronte Precision Engineering and B&B Precision Engineering.
