Assess your specified steel part across machining and secondary operations. Confirm the grade, supplied condition, heat treatment, critical features and final inspection state before the route and quotation are agreed.
Jaquent reviews carbon, stainless and tool-steel parts for CNC turning, milling and suitable wire EDM operations. Typical requirements include shafts, fixtures, fittings and hardened profiles. Start with the exact steel specification and supplied condition, rather than treating a family name as an interchangeable material choice.
For heat-treated work, identify target hardness, sequence and any final grinding or EDM allowance. For corrosion duty, supply the medium, concentration, temperature and other relevant conditions; 304 or 316 alone is not a guarantee of suitability. Any alternative grade or changed treatment needs customer agreement.
The examples below support discussion of material and process requirements. For a broader comparison before choosing a grade, use the CNC material selection guide.
If hardness is specified, identify the required condition at delivery and any features that must be sized after heat treatment. Mark surfaces that may retain finishing stock and the dimensions that must be accepted after it is removed. State any required hardness test or record in the RFQ so its method and scope can be reviewed.
Review the specified 1045 condition, required hardness and finishing sequence for shafts, hubs, pins or fixtures. Stock and heat-treatment scope are confirmed for the project.
State the exact grade and supplied condition. Corrosion exposure, finish, cleaning and required documentation determine the review; grade names alone do not establish application suitability.
| Specified family | Project questions | Machining considerations | Condition to confirm | Secondary operations to scope |
|---|---|---|---|---|
| 1045 carbon steel | What strength, hardness and final features are required? | Workholding, residual stress and movement after treatment | Exact specification, supplied state and target hardness if treated | Heat treatment, final machining/grinding and corrosion protection |
| 304 stainless steel | What medium, finish and cleaning requirements apply? | Work-hardening, chip control and thread/bore burrs | Specified product form and supplied condition | Passivation, polishing or other finish only when specified |
| 316 stainless steel | What exposure and service conditions must the selected grade address? | Tool access, burrs, heat and final surface condition | Exact grade and condition; suitability confirmed by the specification owner | Specified finish and documentation |
| Tool steel | Which grade, hardness, wear and final geometric requirements apply? | Hardness and treatment sequence affect the finishing route | Grade, supplied condition, treatment and final hardness | Heat treatment, grinding or wire EDM as quoted |
The steel-blade case below records owner-reported manufacturing facts and customer acceptance. No material certificate, dimensional readings or customer acceptance report was supplied for independent review. Its video shows turning, while the case text describes other operations.
Supplied hardness and the required final condition affect tool choice, machining allowance and the sequence of finishing operations. State whether the stock arrives hardened and which features must be completed after treatment.
Work-hardening, chip control and burr removal need review for the specified stainless grade. Identify blind bores, threads and edges where access or burrs could affect assembly, cleaning or acceptance.
Residual stress and cutting heat can change a part’s shape. Thin sections, large material removal and the condition after unclamping affect the roughing, finishing and inspection plan.
Heat treatment can change size and form. Identify target hardness, final datums and which bores, faces or edges need finishing afterwards; confirm allowance and sequence in the agreed route.
This order involved 300 steel cutting blades for a sandpaper-cutting application. Made from AISI O1 / 1.2510 tool steel, the blades required particular attention to cutting-edge machining, with edge thickness and straightness as the key control points.
The work focused on finishing the cutting edges while meeting the specified edge-thickness and straightness requirements. The dimensional requirements and inspection values remain confidential.
The blades underwent heat treatment before grinding was used to finish the cutting edges. Edge thickness and straightness guided the final machining and inspection.
Edge thickness was checked with a micrometer. For straightness checks, the blade was stably supported, and a dial indicator mounted on a stand was moved along the cutting edge to check variations along its length.
The batch passed customer acceptance, and the 300 blades were shipped.

Turning footage from the collected case materials. The clip shows tool motion and coolant during turning. Heat treatment, edge grinding, and inspection are described in the case above.
The turning image provides process context for chip and heat management. The flange and fitting photographs are representative geometry; they do not independently establish steel grade, hardness or a dimensional acceptance result. Confirm those requirements through the drawing, agreed route and requested records.
Steel grade, supplied condition, residual stress and heat treatment affect how a feature is held. Confirm which surfaces are finished and accepted after treatment.
Apply individually specified requirements and any general drawing tolerance to their stated scope and edition. Where neither applies, ±0.10 mm is a common quotation basis. Selected milling or turning features may be reviewed to ±0.01 mm. For a five-axis route, designated critical features may be reviewed to ±0.005 mm where material and geometry allow, confirmed through DFM. Swiss-turned linear features and critical wire EDM features have their own process-specific references; confirm the applicable service and feature rather than transferring one figure to every operation.
Pre-shipment inspection at the authorized manufacturing facility follows the drawing and agreed plan. Every-part checks apply to named features when specified; other checks can follow agreed sampling. Request material records, traceability, dimensional reports, customer FAI forms or a CoC in the quotation, with coverage and format confirmed. See functional tolerances and GD&T and inspection scope and required records.
Stress relief, quench and temper, passivation, black oxide, plating, blasting, brushing, and electropolishing are available or coordinated per project. Specify supplied versus hardened condition, target hardness, sequence, coating allowance, and masked critical fits. Hardware install can ship with the same order when specified.
