Buyer FAQs
Does RF Machining sell standard washers?
No. RF Machining focuses on custom machined washers, spacers, distance rings and small turned parts made according to customer drawings or samples, not catalog hardware washers.
Can washers and spacers be made in multiple small batches?
Yes. Small-batch and multi-specification orders can be quoted when the drawing defines material, size, thickness, tolerance and inspection requirements.
Can surface treatment be included for washers or spacers?
Surface treatment such as heat treatment, nitriding, hard chrome plating, polishing or hardfacing can be included when specified by the drawing or RFQ.
What information helps quotation?
Please send the drawing or sample photos, material, quantity, thickness, ID, OD, hole or slot features, flatness or parallelism requirements and any surface-treatment notes.
