Starrag UK has announced a machine rental scheme for its Bumotec range of multi-axis mill-turn and machining centres to provide potential users with a cost-effective way to capitalise on the benefits of multi-tasking, single set-up machining using world-leading machining technologies for the production of complex small to medium-sized parts.
The scheme allows customers to avoid relatively high upfront capital expenditure yet immediately benefit from the machines’ ability to drastically reduce lead times by completing a range of different tasks in a single setting.
As with all machines offered by Starrag UK, the Bumotecs can be configured exactly to suit users’ needs in line with Starrag’s ‘Engineering precisely what you value’ strategy – for dedicated throughput or for smaller batch work and at an affordable monthly rental payment, with an option to purchase at any time.
The scheme applies to the s191 and s181 Bumotec machines which are ideal for users in the medical, watchmaking and jewellery sectors, for example. In one example, the five-axis s181 turn-mill machining centre machined a surgical hook complete from 25 mm titanium bar in under 14 minutes compared with 20 minutes by conventional single-station machining.
Machining on the s181 is based around an innovative two-workstations concept; equipped with five driven tools, the second workstation works on the rear side of one part while the main spindle completes another part. With two tools simultaneously cutting, the result is significant reductions in cycle times. The machine’s tool breakage detection system, which also operates in ‘hidden’ time, encourages optimised uptimes, too.
With a footprint of just 3.5 m², the s181 has a 30,000 revs/min HSK-40 tool spindle (optionally 40,000 revs/min), can handle bar of 32 mm diameter and has a 90-tool magazine. In addition, a 20-pallet storage system enables uninterrupted 24/7 production.
