The load system is comprised of four separate magazines, each operating independently. Each magazine is identical to the next. The magazines are numbered from left to right, one through four. Magazine four is furthest from the ID grinder. In principle any magazine may be used, and all magazines will be used as much as the next. In reality because of the speed of the machine, only one or two magazines are ever used. The logic of the system has been designed so magazine 4 has highest priority, followed by magazines 3, 2 and 1.

 

The ID grinder is set up to surface grind the inside diameter of the brake block. A special sanding belt is used to achieve the grind.

 

The OD grinders are set up to grind the outside diameter of the brake block. There are two OD grinders. The first unit is the ROUGH grinder. It is used to remove the majority of the excess brake material. The second unit is the FINE grinder. It is used to produce the tight tolerance finished product. Fundamentally both units operate in the same manner. The OD grinder has the ability to grind eccentric as well as parallel blocks on a common fixture. A servo drive system allows the cutters to precisely follow the position of the feed drum to create the desired block dimensions. The block dimensions are entered at the display screen. A RECIPE system has been included to minimize the settings required by the operator.

 

The paint unit is a roll on paint system that will paint one edge of the brake block only. Immediately before the paint system there is a part flipper. If the opposite side needs to be painted, the part flipper is utilized to expose the opposite block edge. The quantity of paint applied can be easily increased/decreased by a hand wheel located on the back of the device. Only paints that remain wetted (do not dry easily on non porous surfaces) can be used in this system.
