FROM RESEARCH TO RFQ
Use the Drawing as the Single Source of Truth
Website content explains general capability. Your approved 3D model and drawing define the actual part, revision, tolerances, material, finish and acceptance requirements.
- Match every submitted file to the same revision.
- Flag critical-to-function dimensions and interfaces.
- State cosmetic zones and unacceptable appearance defects.
- Identify any required certificates or inspection templates.
QUICK ANSWERS
Resource FAQ
Which 3D model formats are best for a quotation?
STEP or STP files are normally the clearest choice for 3D geometry. A dimensioned PDF or DWG drawing should accompany the model when tolerances, threads, finishes or inspection notes matter.
Can VOGUC quote from only a 2D drawing?
Some straightforward parts can be reviewed from a complete 2D drawing, but a 3D model usually improves geometry interpretation and quotation speed.
Why must critical tolerances be identified?
Tight tolerances can change the machine, setup, inspection method, yield risk and cost. Identifying only function-critical dimensions helps build a more practical process.
When is the production lead time confirmed?
Production lead time is confirmed during quotation after reviewing quantity, material availability, geometry, finish and inspection requirements.
Where should I start if I do not know the machining process?
Start with the part function, geometry, material and critical requirements. The capability pages explain common process fit, while an engineering review can determine whether milling, turning, 5-axis machining or a combined route is practical.
Which inspection evidence should be agreed before production?
Agree the required material certificate, dimensional or CMM report, full-dimensional scope, sampling plan and document format during quotation so the acceptance criteria are clear before machining begins.
Ready to move from research to quotation?
Send the model, drawing, material, quantity and inspection requirements. MOQ is 1 piece, and samples can be completed as fast as three days after review.
