In some cases the drill head bore and spindle housing may be considerably unstable due to abnormal wear and galling from metal chips and fragments being retracted up into the bore are. If this condition exists, the bore can be oversized slightly to clean up and a new spindle housing produced to match resulting in a very stable spindle condition.

HMT's answer to preserve the spindle housing and drill head bore life span, preventing unstable spindle conditions, is the addition of a spindle wiper assembly (wiper housing cup shown being produced). The addition will limit the overall existing travel capability by 1/2 inch.

The intermediate slide is disassembled, inspected and modified with a tubular support rib (if not present) and limit switch conductor junction box resulting in limited wiring exposure.

Upon completion of the modifications, the slide is cleaned, scraped in by hand and prepared for paint. Additionally, the front saddle plate is modified to accept the new ball screw adaption block.

The base frame work, after breakdown, is reassembled and prepared for painting. Prior to this step, the longitudinal rails are inspected, cleaned and scraped along with the travel gear rack.

| After painting, the completed frame assembly looks as good as new. At this time, the process of final assembly begins.
