Shaft Types and Manufacturing Capabilities

Yes. Jinhua Machinery reviews customer drawings, samples, material requirements, tolerance targets, heat treatment needs, and surface finishing requirements before quoting.

We support custom, forged, geared, splined, worm and pump designs, plus steering, input, output and assist components, pinions, bushings, hubs, collars, and related transmission parts.

For suitable shaft parts, forged blanks can be reviewed together with CNC machining, grinding, heat-treatment requirements, surface treatment and inspection. Provider responsibilities and required records are confirmed during quotation.

Please send the drawing and revision, material, critical dimensions and tolerances, surface and heat-treatment requirements, annual usage, batch volume, inspection or PPAP documents, packaging and delivery target.

List each stage separately in your RFQ, with its quantity, delivery target and intended use. Use the same drawing revision and acceptance requirements as the comparison basis, and identify any differences between stages. Ask each supplier to separate any one-time charges from unit prices and clarify the included inspection documents, packaging and delivery terms. Before comparing unit prices, confirm whether the later order covers the same scope as the sample or first batch.

State the requested supply basis in your RFQ and ask the supplier to confirm whether it can accept that scope. If you plan to supply blanks, include their material, starting condition, machining allowance and available records, then clarify responsibility for their suitability and condition on receipt. If you want finished shafts, ask who is responsible for blank sourcing, machining, treatments, inspection records and packaging. Both parties should agree how unsuitable blanks, material replacement and work outside the quoted scope would be handled before placing the order.

Send the current drawing revision and mark changes to geometry, material, treatments or acceptance requirements. For a repeat order, reference the earlier quotation or order and state whether quantity, delivery target, packaging and required records have changed. Ask the supplier to confirm the revision and scope used for the new quotation, including any effect on pricing or earlier sample acceptance. Agree which documents govern the new order before relying on an earlier quotation or sample approval.
