CNC Gear Cutting 4340 Alloy Steel

VT machining specialises in CNC Gear Cutting 4340 Alloy Steel. Because 4340 Alloy Steel is high-strength and hardenable, and its machinability is good in annealed condition; machined soft then heat-treated to final hardness, we plan each job around the grade to protect accuracy and surface quality.

CNC Gear Cutting Capability for 4340 Alloy Steel

  • Cr-Mo / Ni-Cr-Mo grades
  • High strength & hardenability
  • Tolerance to ±0.01 mm
  • Heat-treatable to 30–55 HRC

Machining 4340 Alloy Steel with CNC Gear Cutting

The machinability of 4340 Alloy Steel is good in annealed condition; machined soft then heat-treated to final hardness. For CNC Gear Cutting we select tooling, feeds, speeds and coolant to match, keeping the 4340 Alloy Steel workpiece stable and the result accurate.

Because we machine 4340 Alloy Steel regularly, proven settings shorten setup and keep quality repeatable across reorders.

Secondary Operations & Finishing

We complete 4340 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.

CNC Gear Cutting 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.

Design Tips for CNC Gear Cutting 4340 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 4340 Alloy Steel gears right the first time. If you send your model early, we will return practical DFM feedback before you commit to production.

CNC Gear Cutting Quality & Inspection

Consistent quality comes from disciplined process control. Critical dimensions on 4340 Alloy Steel parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.
