Grinding and Milling Options
Each catalog reference carries its selected scope into the quotation form. Finished dimensions, material records and acceptance follow the approved order.
Two-side ground + four-side milled
Precision grinding on two reference faces, with the four remaining faces milled. Thickness and length/width have separate tolerances.
- Length / width
- ±0.10 mm
- Thickness
- ±0.05 mm
- Parallelism
- 0.04 mm / 100 mm between the ground reference faces
- Material condition
- Confirm the material condition for the order
- Size scope
- Maximum processing: 1200×800×400 mm; process review required
Material sourcing, delivery condition and any hardness requirement are confirmed in the quotation. Finished dimensions, reference faces, inspection and machining allowance follow the approved drawing. This grade is outside the published E1 scope.

Grade designations are listed separately; no automatic equivalence or substitution is assumed. Per-100-mm parallelism does not define whole-plate flatness or surface roughness.
Drawing and Quotation Checklist
- State the delivery condition and any subsequent heat treatment, polishing or corrosion-related service requirement. Plate grinding does not by itself define mirror polish or surface roughness.
- Mark finished length, width and thickness, reference faces, tolerances, datums and any whole-plate geometric requirements.
- Specify quantity, required material/hardness/dimensional records, any requested UT scope and delivery destination.
Include quantity, drawing revision, required inspection documents and delivery destination. Single-piece and small-batch inquiries are accepted.
Prepare a 1.2083 plate inquiryInspection and Production Planning
MTC material documentation, hardness and dimensional inspection reports can be requested. UT reports are available on request with an agreed scope. Regular plate sizes range from 100×100×20 to 800×600×300 mm; maximum processing size is 1200×800×400 mm, subject to grade, condition and finish review. This maximum does not carry the E1 tolerance.
Production schedule: 3–7 working days. Working days exclude weekends and statutory public holidays in China. The clock starts on the next working day after formal PO receipt, final drawing/specification approval and applicable deposit receipt are all completed. Transport time is separate.
