What surface finish is achievable on A2 Tool Steel with CNC 5-Axis Machining?
Surface finish on A2 Tool Steel is controlled to your specification; we confirm the achievable Ra against your callout.
Why is A2 Tool Steel a good choice for CNC 5-Axis Machining?
A2 Tool Steel is wear-resistant and hardenable for tooling, which makes it well suited to CNC 5-Axis Machining. We tune the process to the alloy so the finished A2 Tool Steel machining part meets your dimensional and functional requirements.
What tolerances can you hold for CNC 5-Axis Machining A2 Tool Steel?
Achievable tolerances for A2 Tool 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.
What is CNC 5-Axis Machining A2 Tool Steel and how is it done?
CNC 5-Axis Machining A2 Tool Steel refers to five-axis machining orients the tool to complex geometry in one setup, reducing fixturing and improving accuracy. Applied to A2 Tool Steel — wear-resistant and hardenable for tooling — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
