Waukesha Bearings invests in two new Doosan Puma 2600 lathes.

Glasgow-based precision manufacturing specialist - Waukesha Bearings Ltd – has recently invested in 2 x new Doosan Puma 2600 (10” chuck/76mm bar diameter) lathes supplied by Mills CNC.

The lathes, installed at Waukesha Bearing’s 50,000sq ft production facility in August 2010, are being used to manufacture the company’s market-leading and innovative INPRO/SEAL custom-engineered system and bearing protection products, used extensively in the oil/gas, power generation, chemical, mining and other processing sectors.

The investment catalyst

The two Puma 2600 lathes form the mainstay of a new, purpose-built manufacturing cell (which also includes a vertical machining centre) designed to ramp-up production of the company’s INPRO/SEAL product line to meet (and exploit) the growing demand for these products in Europe.

Says John Murray, Waukesha Bearing’s Engineering Manager:

‘Our INPRO/SEAL products were originally being manufactured by our facility the US.

‘But the decision to penetrate and increase market share in European markets and to meet the subsequent increase in demand meant that we needed to set up a ‘similar’ production facility here in the UK.

‘By replicating the US manufacturing operation at our Glasgow facility we knew that we would be able to provide customers in Europe with a proven, easily-transferable and cost-efficient method of manufacture, as well as a fast (often same day shipment on most products) response.’

Because the US manufacturing operation used Doosan Puma lathes, and highly recommended them for their accuracy, reliability and value...it was not surprising that Doosan lathes became the preferred turning technology for the proposed new UK manufacturing cell.

Similar but not quite the same

Having said that there are some differences (some may say improvements) between the US operation and the manufacturing cell just created in the UK.

Because, instead of the Doosan Puma 280 lathes used in the US (and which have now been phased out), the UK cell features their replacement - the new-series Puma 2600 machines, which were launched by Mills CNC in the UK at this year’s (2010) MACH Show.

These machines, with their ultra-rigid design and construction, provide Waukesha with improved part accuracies, and a more reliable and thermally-stable machining process. The new Puma 2600 series lathes, like their predecessors, are equally cost-competitive and reliable too.

 Continues John Murray:

‘The new Doosan machines, with their 22kW 3,500rpm spindles, 12-station turrets and user-friendly Fanuc control have given us the power, flexibility and productivity we were looking for.

‘To reduce set-up times, minimise non-cutting times and reduce overall part cycle times – the new Puma machines purchased were equipped with quick-change power chucks.’

The Puma 2600 lathes in action

One of the most successful products being machined on the new Doosan Puma 2600 lathes is the patented INPRO/SEAL bearing isolator.

Manufactured from bronze tube in one-hit on the Pumas, and machined to exacting standards and high tolerance

(within 0.005mm)

, the isolator features a unitised rotor and stator configuration that provides customers with permanent bearing protection (preventing lubrication loss and contamination ingress) thereby eliminating downtime and the need for continual maintenance.

INPRO/SEAL bearing isolators (manufactured in a range of different sizes by Waukesha) are used to protect motor and pump bearings, machine tool spindles, turbines, fans, gear boxes, paper machine rolls and many other types of rotating equipment.
