CNC Machining
The new DNM 4500, like the other machine tools the company has at its disposal, is being used to machine a range of high precision components and families of parts (i.e., housings, enclosures, flanges, valves, actuators etc.), for proprietary flow meter and scientific instrumentation products, designed in-house by the company. Once machining and inspection have been completed, parts are sent out for different surface treatment operations (i.e., plating, powder coating etc.), before coming back to the company for final assembly, testing and delivery to a range of customers operating in the electronics, and process control and measurement sectors. Parts machined on the new DNM 4500 are typically made from solid aluminium, mild steel and stainless steel bar and billets and are machined in a range of batch sizes(prototypes and one-offs through the thousands-off) using advanced work-holding and fixtures that include pallets and tombstones.
Part tolerances are tight but not excessively so, with the main machining requirements being consistency, repeatability and fast processing speeds. A new machining centre – the need. With demand growing for its design, machining and assembly services, the company made the decision, back in 2022, to improve its milling capacity and capabilities. Two, older machines the company had at its disposal were creating production pinch points that were affecting throughput and output. After careful consideration the decision was made to replace both with a new, higher specification machining centre. John Watts, owner and director of DN Solutions explains: “We provide comprehensive, high-quality machining services to customers and are a vital cog in their process chains. As such, we need to be able to anticipate and respond quickly to their changing production
