B 355
Brake drum and brake disc turning and grinding machine
HIGHLIGHTS
- Extremely low initial cost.
- Due to its modular design 4 model versions are available.
- Technically up-to-date “intermittent feed”.
- High load capacity of work arbor (500 kg!) due to far forward position of spindle bearing.
- Short toolholders due to axially adjustable base slide, no vibrations in consequence.
Useful for
- Turning of brake drums of trucks, trailers and buses
- Grinding of brake drums of trucks, trailers and buses
- Turning of brake discs (B 355a) of trucks, trailers and buses
- Turning of brake drums of industrial trucks, vans and cars
- Turning of brake discs (B 355a) of industrial trucks, vans and cars
- Turning and grinding of flywheels (B 355a) of trucks and buses
- Turning and grinding of flywheels (B 355a) of industrial trucks, vans and cars
The B 355 is the ideal machine for vehicle repair shops in which brake reconditioning is not carried out frequently enough to warrant a large, permanently operated drum turning machine.
- Extremely low initial cost.
- 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.
- Tool feed by electronically controlled DC motors. The feed in both directions is infinitely variable and “intermittent”.
- Optional LCD position displays for drum diameter and spindle speed.
- 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).
- Short toolholders due to axially adjustable base slide, no vibrations in consequence
- The powerful and effective dust and chip extraction provides a healthy and clean work station
