New vertical turning centres bridge gap in market

Mills CNC 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 between DN Solutions’ smaller Puma PV 400 series of vertical turning centres and the company’s large PV 8300 and PV 9300 ranges. It is aimed at component manufacturers machining mid-sized parts – such as discs, rings, wheels, hubs and housings – for heavy-duty aerospace, automotive, oil and gas, and power generation applications.

The two-axis PV 6300 and the PV 6300M, a vertical turning centre with driven tooling capabilities (5000 rpm), have a box guideway design and reinforced spindle motors. This design ensures 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 26 kW/2,000 rpm/1,116 N-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 37 kW) and higher spindle torque (1,638 Nm) options are also available.

Both machine models have a maximum turning diameter of 630 mm and a maximum turning length/height of 600 mm. Linear scales 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 eight-tool position (CAPTO C6) ATC to help improve productivity and process efficiencies. This capability comes into its own when customers are machining complex parts involving the use of many tools, minimising potential machine downtime caused by tool change operations.

The machines can be supplied with the latest FANUC iPlus with 15” touchscreen iHMI or Siemens 828D controls. Moreover, because they are ‘automation-ready’, the machines can be integrated with Mills CNC’s SYNERGi automation systems to improve productivity and facilitate lights-out operations.

Features that include improved swarf evacuation, auto-tool setters, large-capacity coolant tanks (340 litre) and, for brake disc machining, servo-straddle tooling, improve performance and flexibility.

Says Tony Dale, Mills CNC’s Group CEO: “The new PV 6300 series has raised the bar for vertical turning centres and provides customers with unrivalled productivity, precision and process reliability, especially for heavy-duty industrial applications.”
