On-the-truck disc lathe
The TD 502 machine completely changes the concept of disc reconditioning in trucks and buses.
No more time loss while disassembling the disc for bench turning. Now machining operations can be done directly on the hub.
This revolutionary idea has lead to the creation of a machine that minimizes the set-up time.
It is mounted on a swinging and height-adjustable self-aligning saddle that always guarantees the perfect matching between the machine and the hub (with no need for further alignment or centering operations with a comparator). The monolithic cast iron machine body has an empty central part that does not interfere with the truck reducer (especially on rear axles). This ensures that the machine positioning is very close to the disc, for a much more precise reconditioning operation.
Furthermore, the intermittent and adjustable feed ensures a precise finishing on any surface.
