Scraped machine ways and machine beds

Our work

What does a scraped machine way look like?

Photos from the job, in the installed machine and on beds already out of it. Each one says what it shows.

  • Rotary table with ring gear, out of the machine, on a shop floor. Both circular ways are spotted in blue, the contact shows as even spots around the full circumference.

  • NIVELTRONIC electronic level on a precision straightedge across the magnetic chuck of a surface grinder, with the Okamoto 157 DXNC nameplate above.

  • Long machine bed with both ways spotted in blue. Measuring points are marked in red along the edge, and two hand scrapers with ball handles lie in the middle.

  • Mahr Zentimess dial indicator on a magnetic base, set against the side of a machine bed. Measuring points are circled on the casting in red marker.

  • Lathe with Boehringer lettering on the headstock. A granite straightedge lies in front of the bed, with an indicator stand on it and its arm reaching over the ways.

  • Machine bed out of the machine, seen from above. Both ways are spotted in blue over the full length, with the raw cast ribs in the middle.

  • Two guide strips on a machine bed, spotted in blue, seen at an angle from above. The German word Leiste (strip) is written on the casting in red marker.
