Blind Hole Broaching:
Splines, Hex, Squares, Specials
.100 to 1.125 P.D.
12/24 to 150 D.P.
Blind Hole Broaching (done at Broach Masters) is an economical and efficient means of internal Spline production. This operation offers good concentricity to ground location Journals and good surface finish when part material is hardened to Rc32-36, it is competitive with shaping parts under ¾ P.D. and the best choice for splines under 3/8 P.D., for quality and price. The main advantage is that it is very repeatable in size and does not have any variance because of cutter deflection.
