Mills CNC introduces a new range of heavy-duty, high-efficiency vertical turning centres into the market.
Mills CNC, the exclusive distributor of DN Solutions’ and Zayer machine tools in the UK and Ireland, has introduced a new range of heavy-duty vertical turning centres into the market.
The new PV 6300 range, comprising two different models, bridges a gap in the market slotting seamlessly in-between DN Solutions’ already established smaller Puma PV 400 series of vertical turning centres and the company’s large and popular PV 8300 and PV 9300 ranges, and is aimed at component manufacturers machining mid-sized parts (i.e., discs, rings, wheels, hubs, housings etc.), used in and for heavy-duty aerospace, automotive, oil and gas and power generation applications.
The 2-axis PV 6300 and the PV 6300M, a vertical turning centre with driven tooling capabilities (5000rpm), have a box guideway design and reinforced spindle motors that ensure high-precision and reduced vibration when machining hard and difficult-to-machine materials that include heat treated stainless steels and corrosion resistant super alloys.

With up to 18” chuck sizes, PV 6300 and PV 6300M vertical turning centres are supplied with advanced and powerful 26kW/2,000rpm/1116N-m spindles as standard, allowing end users to ramp up speeds and feeds and take more aggressive depths of cut as a route to boosting their productivity. Higher spindle power (up to 37kW) and higher spindle torque (1638N-m) options are also available.
Both machine models have a maximum turning diameter of 630mm and a maximum turning length/height of 600mm. Linear scales on the machines’ axes are available as an option ensuring that high precision and positional accuracies are achieved and maintained.
In addition to their fast and accurate servo-driven 12-station turrets, PV 6300/6300M machines can be equipped, as an option, with an additional 8-tool position (CAPTO C6) ATC to help improve productivity and process efficiencies.
The access to additional tools comes into its own when customers are machining complex parts involving the use of many tools (beyond the capacity of tools stored in the machines’ turrets), and minimises potential machine downtime caused by tool change operations.
The machines can be supplied with the latest Fanuc i Plus with 15” touchscreen iHMI or Siemens 828D controls and, because they are ‘automation-ready’ can be integrated with Mills CNC’s high-productivity and highly-flexible SYNERGi automation systems to improve productivity and facilitate lights-out, unattended operations.
Features that include improved swarf evacuation, auto-tool setters, large-capacity coolant tanks (340L) and, for brake disc machining, innovative servo-straddle tooling, improve the machines’ performance and flexibility.
“The new PV 6300 series has raised the bar for vertical turning centres and provide customers with unrivalled productivity, precision and process reliability, especially for heavy-duty industrial applications.”
