The Blanchard No. 18 Surface Grinder is a surface grinding machine manufactured by Blanchard Machine Co.[1][2]
What it is
General reference — not yet source-verifiedBlanchard grinders use a segmented grinding wheel mounted on a vertical spindle to grind flat surfaces on workpieces that are held on a rotating magnetic chuck.
How it works
General reference — not yet source-verifiedA Blanchard surface grinder operates with a vertical-axis grinding wheel that rotates above a rotating worktable, typically a magnetic chuck.
Workpieces are placed on the magnetic chuck, which rotates beneath the grinding wheel as the wheel is fed downward to remove material from the entire surface of the parts.
Where it fits in the process flow
General reference — not yet source-verifiedSurface grinding is a finishing process applied after rough machining or sawing to achieve flatness, parallelism, and surface finish.
Upstream processes include sawing, slicing, or rough cutting of materials; downstream steps may include polishing, inspection, or further precision machining.
Applications
General reference — not yet source-verifiedCommon applications include grinding large flat surfaces on castings, weldments, dies, molds, and machine tool components, as well as for thinning or flattening semiconductor substrates and other technical ceramics.
