Q1: Can you fabricate this multi-step grooved shaft from my engineering drawings?

A1: Yes. We strictly manufacture parts according to your 2D/3D drawings, including tolerance, material and surface finish requirements. Engineering drawings are required for accurate quotation.

Q2: What stainless steel grades are available for this grooved shaft?

A2: 303 and 304 stainless steel are our standard options. 316 stainless steel is available on request for higher corrosion resistance.

Q3: What is your lead time for samples and mass production?

A3: Prototype samples take about 7–10 working days. Mass production lead time depends on quantity and complexity, we will confirm schedule after drawing evaluation.

Q4: What surface treatments can you provide?

A4: Stainless steel passivation to enhance anti-corrosion performance. Additional surface treatments like polishing can be arranged upon demand.
