Brake drum and brake disc
turning and grinding machine

HIGHLIGHTS
- Modularer Aufbau; in 4 Ausführungen lieferbar
- Technically up-to-date through “intermittent feed”
- High load capacity of work arbor (500 kg!) due to far forward position of spindle bearing
- Kurze Werkzeughalter durch axial verschiebbaren Unterschlitten, dadurch keine Vibrationen
APPLICATIONS
- Turning of brake drums of trucks, trailers and buses (with and without wheels)
- Grinding of brake drums of trucks, trailers and buses
- Turning of brake discs (preferably with hub) of trucks, trailers and buses (B 355a)
- Turning of brake discs of industrial trucks, vans and cars
- Turning of brake discs of industrial trucks, vans and cars (B 355a)
- Turning and grinding of flywheels of trucks and buses (B 355a)
- Turning and grinding of flywheels of industrial trucks, vans and cars (B 355a)
Professional machine for commercial vehicle workshops performing brake repair work
- Due to its modular design 4 model versions are available:
- B 355t/1 – 3 spindle speeds: 33/60/100 rpm
- B 355t/2 – steplessly variable variator drive: 20 – 120 rpm
- B 355a/1 – 3 spindle speeds and transverse drive
- B 355a/2 – steplessly variable variator drive and transverse drive
- High load capacity of work arbor (500 kg!) due to far forward position of spindle bearing
- Axially adjustable lower slide for the use of short and solid tool holders
- Tool feed by electronically controlled DC motors. The feed in both directions is infinitely variable and “intermittent”
- LCD position display for quick drum diameter and spindle setting (optional)
- Simultaneous turning and grinding of brake drums. Saves time and gives perfect surface finish.
- Precision turning of both sides of brake discs in one operation (B 355a)
- The powerful and effective dust and chip extraction provides a healthy and clean workstation
