At left is a 46'' Bullard cross rail as received from the customer. The
turret and boring ram assemblies were shipped separately. Two days of cleaning were
required before disassembly. |
To the right is the cross rail after partial disassembly.

At the left can be seen the cross rail being ground on our smaller way
grinder. Tolerances are .0001 per foot for straightness and parallelism. We
are holding .00005 per foot. Hand scraping could not begin to achieve this accuracy!
|
| At the right is the finished ground cross rail. Micarda has been bonded
to the mating sides of the saddles to compensate for material removed in way grinding and
wear on the saddles. |
