Starrag’s scheme allows customers to avoid relatively high upfront capital expenditure, yet immediately benefit from the ability of Bumotec machines to reduce lead times by completing a range of different tasks in a single setting. As with all machines offered by Starrag UK, Bumotec models can be configured exactly to user requirements in line with the company’s ‘Engineering precisely what you value’ strategy. An option to purchase is available at any time.
The scheme applies to the s191 and s181 Bumotec machines, which are suitable for users in the medical, watchmaking and jewellery sectors, for instance. In one customer case example, the 5-axis s181 mill-turn machine produced a surgical hook complete from 25 mm titanium bar in under 14 minutes, compared with 20 minutes using conventional single-station machining.
Machining on the s181 is based around a two-workstation concept. With two tools cutting simultaneously the result is significant reductions in cycle times. The machine’s tool breakage detection system, which also operates in ‘hidden’ time, is another factor that contributes to higher levels of uptime.
With a footprint of just 3.5 m², the s181 has a 30,000 rpm HSK-40 tool spindle (optionally 40,000 rpm), can handle bar of 32 mm diameter and houses a 90-tool magazine. In addition, a 20-pallet storage system enables uninterrupted 24/7 production.
