The S 331 brake shoe grinder with grinding roll is a low priced but high effective machine for cleaning and derusting brake shoes. Uneven corrosion and oxidation deposits as well as adhesive residues are removed from old brake shoes by grinding. Cleaning of the brake shoe surface after removal of the old linings is essential for a secure platform and vibration free seating of the new lining.



The inclination of machine table towards grinding roll guides the brake shoe without effort.

The working radius can be adjusted by the adjustable buffer.

The flat grinding table ensures a proper seat of the brake shoe during operation and thus a perfectly flat ground shoe.

The change of the grinding belt is easy and quick.
 
Capacity: Brake shoes up to 10" (270 mm).

The development and manufacture of vertical turning and grinding machines is a HUNGER speciality. We have been active in this field for more than 30 years. More than 5000 satisfied users of HUNGER vertical turning machines have endorsed this principle.

Advantages of the vertical design:
all workpieces can be clamped and centered accurately on the horizontal work-table without any problem. The weight of the workpiece is distributed uniformly. As workholding devices can be used three-jaw chuck, locating flanges, taper plugs and special clamping devices.
   
The U 305 is designed for universal application, as well as for easy and convenient operation. It is precise in its operation and has a nearly unlimited life. The main spindle is carried on taper roller bearings fitted for life.
   
The speed of rotation of the work-table is steplessly variable. The feed is "intermittent". The vertical and horizontal feed drives are powered by electronically controlled, steplessly variable DC motors.

The profiling of brake linings in position, i.e. on the axle, guarantees safe braking values from the outset. Furthermore, the linings make contact over their full working surface. Overloading and consequent over-heating caused by partial contact is eliminated and both brake lining and brake drum life extended.

The F 308 can rotate in either direction. This enables all brake linings to be turned on the vehicle in the same direction as the wheel rotation, so that the braking forces on both wheels of the vehicle are particularly closely matched.
 
The F 308 is supplied complete with a lifting and mounting trolley which makes the machine extremely easy to handle. For skimming brake linings on hub reduction axles and on conventional stub axles the machine can be attached without any problem.
 
The skimming process is carried out fully automatically up to the automatic termination of the intermittent feed, when the preset turning depth has been reached. Machining times are very short due to the speed of rotation of 100 rpm and a steplessly variable feed. On the basis of experience, the feed is set to 0.6 mm/rev. in our works.

The tool slide is equipped with a digital read out which enables a faster, easier and faultless adjustment of the tools.
   
The design of the F 308 allows a toolholder with very little overhang to be used. This results in optimum concentricity, parallelism and surface finish.
