This listing is a length of V-track (54 5/8 inch). The material is steel with an induction hardened 90 degree V on the top. Each track is pre-drilled with the first hole starting at .31 inch from the right side of the track. The 13/64 (.203) drilled holes are clearance for a #10 screw ( 10-32 or 10-24). The hardened V-track will hold up for years of service using hardened #2 V-wheels.
The material is hardened so it is not recommended to cut with a band saw. An abrasive chop saw or cutoff disk in a hand held tool ( like a Dremel) will work fine if you need to cut to a different length. We screw two lengths to both sides of a 3/8 thick x 3" wide cold rolled steel length or an extruded aluminum rectangle to form a slide mount for either our 4" or 6" Z-slides. Typical accuracy of the width of a cold rolled steel or Extruded aluminum rectangle is about .001 inch per foot. The resulting assembly yields an excellent structure on which to build a CNC router, plasma, laser, or other table based CNC machine. Using this material on our desktop CNC routers we typically have .002-.004 total variation per foot. An alternative to using two opposed V-tracks is to use a V-wheel on top and a cam follower on the bottom of a single v-track. The cam follower is slightly pre-loaded to prevent lifting of the V-roller from the track. This concept is used on our moving table machines.
