Need reliable CNC Gear Hobbing 4140 Alloy Steel? VT machining machines 4140 Alloy Steel to tight tolerances and consistent quality. As a material, 4140 Alloy Steel is high-strength and hardenable; we adapt feeds, speeds and tooling to suit.
CNC Gear Hobbing Capability for 4140 Alloy Steel
- Cr-Mo / Ni-Cr-Mo grades
- High strength & hardenability
- Tolerance to ±0.01 mm
- Heat-treatable to 30–55 HRC
Machining 4140 Alloy Steel with CNC Gear Hobbing
The machinability of 4140 Alloy Steel is good in annealed condition; machined soft then heat-treated to final hardness. For CNC Gear Hobbing we select tooling, feeds, speeds and coolant to match, keeping the 4140 Alloy Steel workpiece stable and the result accurate.
Because we machine 4140 Alloy Steel regularly, proven settings shorten setup and keep quality repeatable across reorders.
CNC Gear Hobbing Tolerances & Surface Finish
Gear features are produced to a specified DIN/AGMA accuracy class, with profile and lead controlled for quiet, durable running under load.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
Why 4140 Alloy Steel?
Specifying 4140 Alloy Steel for CNC Gear Hobbing 4140 Alloy Steel is usually about its properties: high-strength and hardenable. Tell us the condition you need and we machine to it.
Secondary Operations & Finishing
We complete 4140 Alloy Steel components with the secondary steps your drawing calls for. We arrange heat treatment, surface treatment, marking and assembly as needed. Tell us the final spec and we will plan the full route so parts arrive ready to use.
Design Tips for CNC Gear Hobbing 4140 Alloy Steel
A few design choices make a real difference to cost and quality. Providing complete gear data (module, pressure angle, profile shift, quality class) lets us produce 4140 Alloy Steel gears right the first time. If you send your model early, we will return practical DFM feedback before you commit to production.
