1. Rapid set-up -Quick exchange clamping systems – 6 screws for complete change -Fully exchangeable between main- and subspindle upto 50 mm bar passage -Standard collets ( W / F type ) 6 for success :

2. Manufacturing of clamping tools on machine - Bumotec uses here the OTTET system from a Geneva company - Manufacturing of form collets on machine ( main- subspindle) - No waiting time from toolmaker - No adaption of collets. Matches the first time – no clamping marks - Use existing contour, just switch G41 / G42 - Can be case gardened for series - Ideal in prototype stage: No panic at design change - W-Ring for ID / OD clamping

3. Example : SPINAL FUSION OFFSET HOOK Step 1 Machine the first 5 sides, starting from a bar Step 2 Machine collet on subspindle = mirror step 1
