VT machining offers CNC Milling for 1095 Steel (UNS G10950 / C100S / SK4), typically supplied annealed or hardened. Very high carbon; machined annealed then hardened for blades and springs.
CNC Milling Notes for 1095 Steel
1095 Steel mills well with conventional strategies; finishing passes are planned to meet flatness and finish callouts.
For estimating, a 100 × 100 × 10 mm block of 1095 Steel weighs about 0.79 kg.

Request a QuoteFrequently Asked Questions
Does CNC Milling 1095 Steel require dedicated tooling?
Most 1095 Steel machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Why is 1095 Steel a good choice for CNC Milling?
1095 Steel is strong, economical and widely available, which makes it well suited to CNC Milling. We tune the process to the alloy so the finished 1095 Steel machining part meets your dimensional and functional requirements.
Can VT machining make custom 1095 Steel parts to my drawing?
Yes. 1095 Steel machining is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
What material thickness or size range suits CNC Milling 1095 Steel?
We machine 1095 Steel across a broad size range; share your part envelope for confirmation.
What tolerances can you hold for CNC Milling 1095 Steel?
Achievable tolerances for 1095 Steel machining depend on the alloy, geometry and feature size. Milling holds positional and dimensional tolerances to around ±0.01 mm, tighter with precision setups. Exact figures are confirmed against your drawing callouts.
Which industries use CNC Milling 1095 Steel parts?
CNC Milling 1095 Steel parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise 1095 Steel components are required.
