What is CNC Gear Hobbing Hastelloy C22 and how is it done?
CNC Gear Hobbing Hastelloy C22 refers to gear hobbing generates gear teeth with a rotating hob synchronized to the workpiece. Applied to Hastelloy C22 — high-temperature strength and oxidation resistance — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Does CNC Gear Hobbing Hastelloy C22 require dedicated tooling?
Most Hastelloy C22 gear cutting work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Why is Hastelloy C22 a good choice for CNC Gear Hobbing?
Hastelloy C22 is high-temperature strength and oxidation resistance, which makes it well suited to CNC Gear Hobbing. We tune the process to the alloy so the finished Hastelloy C22 gear cutting part meets your dimensional and functional requirements.
What tolerances can you hold for CNC Gear Hobbing Hastelloy C22?
Achievable tolerances for Hastelloy C22 gear cutting depend on the alloy, geometry and feature size. We hold tight, repeatable tolerances appropriate to the feature and material. Exact figures are confirmed against your drawing callouts.
