Mitutoyo helps meet customer expectations in the realm of deep hole boring, where diameters are more than 20 mm.
One of the specialties offered by Hone-All Precision Ltd. of Leighton Buzzard, Bedfordshire, is the machining of nickel-chromium-based super-alloy components to tight tolerances. These oxidation and corrosion-resistant materials, typified by Inconel and Hastelloy, are well-suited for service environments subject to extreme pressure and temperature, and therefore, are favorites of the petrochemical industry, however, they are very difficult to machine. Accelerated tool wear is a constant concern. This is particularly true in the case of bored-hole features that sometimes approach three meters in length and which usually have to be finished by honing to meet stringent customer specifications.
Form accuracy shaped up
Due to the length of a typical bore, obtaining the accuracy potential of single-point tooling is impractical, except...
