Prepare gearbox quote pathGearbox housing RFQ FAQ
What should a gearbox housing RFQ include?
Send the 2D and 3D files, bearing-seat tolerances, gasket or cover-face flatness requirements, datum scheme, alloy or T6 notes, machining scope, annual volume, inspection records, and launch timing.
Why are bearing seats important in gearbox housing casting?
Bearing seats control shaft alignment, noise, wear, and assembly life. The RFQ should make bore size, position, concentricity, datum references, machining allowance, and CMM expectations visible before tooling is quoted.
Can Bohua review T6 and CNC assumptions together?
Yes. For A356-T6 gearbox housings, Bohua can review heat-treatment stability, machining fixture logic, critical bores, sealing faces, and inspection records so the quote reflects the real manufacturing route.
When should a reducer housing buyer discuss T6 distortion before quotation?
Discuss it before quotation when bearing-seat position, cover-face flatness, gasket surfaces, oil-seal lands, or machined datums must stay stable after heat treatment and finish machining.
Can a gearbox housing program be quoted as a second-source or transfer-tool project?
Yes. Buyers should share current drawing revision, tooling ownership or duplicate-tooling status, pilot quantity, validation records needed, and anonymous risk category without exposing confidential incumbent-supplier names.
