Micromag 20
The FMB Micromag is a magazine style automatic bar feeder for bar stock diameters ranging from 0.8–20 mm. This precision bar feeder is specifically designed for small Swiss type lathes used for medical applications.
Features: Micromag 20
- Bar diameter capacity: 0.8mm to 22mm (0.031” to 0.866”)
- Automatic loading magazine – 9 linear inches of rack capacity
- Walking beam separation system – drops out of the way when running larger diameter bars (21-bar capacity)
- Polyurethane guide channel system – noise & vibration dampening
- Ultra-quick guide channel and pusher changeovers – 10-min full set changeover, 3 min within same channel set
- Hydrodynamic support via high-volume oil flow into channels
- Separate floor-mounted electric cabinet isolates electronics from vibration
- (1) Guide channel set to be chosen by customer. Several sizes to choose from, each handling a specific stock range. See table above (spindle liner required if channel set is not lathe’s max capacity)
- (1) Universal telescoping front nose and (1) nylon nose I.D. liner specific to pusher
- (1) O.D. bar stock collet to be chosen by customer (specific collet needed for each stock diameter)
- Swiss headstock synchronization device
- Automatic remnant retraction, self-centering gripper
- Custom lathe cable and interface plugs
- Polyurethane bushing blocks (2 pieces)
- Spindle tube nose assembly – available in 5mm, 7mm, 10mm
