Precise and productive

Importantly, the machine features a second, live tool workstation enabling up to 40,000rpm to complement the 90 position automatic toolchanger that serves the 11kW, 6,000rpm main HSK-40 spindle. This additional station effectively doubles productivity by enabling up to five driven tools to work on the rear side of one part while the main tool spindle works on another component.

In one instance – the production of a stainless steel workpiece from 14mm bar – the cycle time on a modern machining centre was 389 seconds. On the Bumotec s181, it took just 254 seconds to complete the part – a 38% productivity increase.

Derived from the Bumotec s191 linear CNC turn/mill centre, a proven solution that utilises linear drives and high level thermal stabilisation to achieve 2.5µm machining accuracies in the six sided, complete machining of workpieces, the s181 is a multi-functional machine designed for the single-set-up, complete processing of complex and high precision workpieces.

With a footprint of just 3.5m² the machine can handle bar of 32mm diameter and, being of modular design, can be equipped with a range of productivity gaining options.

The s181's development was focused on the efficient production of medical, orthopaedic and dental components, as well as surgical instruments, but the new machine will be equally at home in all micro-mechanic industry sectors including watchmaking and jewellery.
