Leave room for the final operation
A ground fit needs a defined final size and a clear process scope. Show which faces may retain milling marks and which require grinding or EDM after hardening.
Metal / CNC MATERIALS
Tool Steel CNC Machining
Machined tooling components, inserts and wear parts to the specified steel grade and heat-treatment route.

Are you buying an annealed blank or a finished hardened tool?
A tool-steel RFQ needs both the incoming and final condition. Milling a soft blank, machining prehardened stock and finishing after hardening are different scopes. OUJI has owner-confirmed tool-steel and high-speed-steel machining experience; a named grade still needs its own heat-treatment and acceptance requirements.
01 / MATERIAL SPECIFICATION
Tool steel grades & conditions.
Match the full designation on your drawing. Frequent machining experience, published project evidence and specifications for review are shown separately.
| Grade / designation | Experience | Include with your drawing | Inquiry |
|---|---|---|---|
| A2 | Specify for review | A2: state whether machining starts annealed and whether hardening and final grinding are included. | Quote grade ↗ |
| D2 | Specify for review | D2: identify wear faces and their final hardness; show dimensions to be accepted after heat treatment. | Quote grade ↗ |
| O1 | Specify for review | O1: include the heat-treatment specification and any distortion-sensitive slender sections. | Quote grade ↗ |
| H13 | Specify for review | H13: give the supplied condition and final hardness; distinguish a machined insert from a fully treated tool. | Quote grade ↗ |
| S7 | Specify for review | S7: identify impact-loaded features and the required treatment specification instead of ordering by grade name alone. | Quote grade ↗ |
OUJI machining experience: confirmed by the company owner, 10 September 2026. Family-level experience does not establish a specific grade, stock condition or customer end use; see individual row and case evidence.
Listed grades do not imply current inventory. Material condition, stock form and documentation are agreed with the quotation.
02 / MACHINING REQUIREMENTS
Make the drawing ready for review.
Focus on the details that change material purchasing, the machining route and finished-part acceptance.
Identify hardness verification
State the scale, range and test location required by the drawing. A hardness requirement should not be presented as an inspection result until the part has actually been tested.
Keep high-speed steel specific
“HSS” identifies a broad family. For a high-speed-steel order, include the full designation, product standard and current condition; it is not an alias for A2 or D2.
ORDER DETAILS
Material, finish and documentation.
Specify the requirements together so the quoted scope matches the finished part you need.

Finishing is coordinated through specialist partners. View surface finishing services.
Should heat treatment be included in the tool-steel quote?
Include it when you need the delivered part in a hardened condition. If you will arrange treatment yourself, state the condition in which OUJI should deliver the machined blank and which dimensions remain unfinished.
Does A2 machining experience cover every tool steel?
No. The owner has identified A2 work and broader tool-steel experience. D2, O1, H13 and S7 entries below are specifications for review, not a claim of identical machining history or treatment capability.
