Drawing or no drawing evidence

With drawing, send the 2D drawing and 3D file if available. Without drawing, send old part photos, measured dimensions, application information, and ask for engineering review before final production. For the detailed workflow when you only have old part photos, see how to prepare a ball screw RFQ with only old part photos.

RFQ checklist

  • With drawing: include total length, thread length, end machining, nut drawing, tolerance, and surface treatment.
  • Without drawing: measure diameter, lead, total length, thread length, shaft ends, nut shape, and mounting holes.
  • Always include: quantity, machine type, application, destination, packing request, and delivery target.
  • Mark uncertainty clearly: write "to confirm" beside any dimension that is estimated.

Send us the best file you have

Send weimute the drawing if you have it; if not, send photos and measurements. Our manufacturing and sales team will reply with a required-dimension list so the RFQ can move from rough inquiry to quotable specification.

FAQ

Is a hand sketch useful? Yes, if it shows the end machining sequence, main diameters, lengths, thread, and bearing positions.

Can a supplier copy from photos only? Photos help identify style, but measured dimensions are still required before manufacturing.
