What condition is required for SKD11 E1 blocks?

The published SKD11 E1 scope is hardened and tempered condition, length/width each ≤600 mm and thickness 10–200 mm. Other conditions or dimensions require separate tolerance review.

Does six-side grinding define surface roughness for SKD11?

The published E1 dimensional and parallelism values do not specify Ra. Add any required roughness, flatness or other geometric acceptance requirement to the drawing.

Can SKD11 be ordered in a single custom-size plate?

Single-piece and small-batch inquiries are accepted. Supply the finished blank dimensions, grade, condition, face finish and requested reports for quotation.

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.

LCD-PL-SKD11-G2

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

Finish dimensions and material condition are agreed for the selected grade. Large plates and additional geometric requirements need drawing-specific review.

LCD-PL-SKD11-E1

E1 six-side precision ground

All six faces precision ground under the published E1 grade, condition and size limits.

Length / width: ±0.02 mm
Thickness: ±0.02 mm
Parallelism: 0.02 mm / 100 mm
Material condition: Hardened and tempered
Size scope: L and W each ≤600 mm; T 10–200 mm

Thickness: ±0.10 mm
Parallelism: 0.08 mm / 100 mm
Material condition: Confirm the material condition for the order
Size scope: Maximum processing: 1200×800×400 mm; process review required

Finish dimensions and material condition are agreed for the selected grade. Large plates and additional geometric requirements need drawing-specific review.

Grade and condition limits

E1 for SKD11 requires hardened and tempered condition, length and width each ≤600 mm, and thickness 10–200 mm. The three dimensional tolerances are ±0.02 mm; parallelism is 0.02 mm per 100 mm. Larger sizes, annealed material or additional requirements need separate review.

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

Use SKD11 consistently in the approved material specification instead of relying on a presumed alternative grade.
If heat treatment remains after delivery, define allowance and acceptance at the supplied condition.
For E1, identify hardened and tempered condition and include whole-span geometry or roughness requirements separately.

Include quantity, drawing revision, required inspection documents and delivery destination. Single-piece and small-batch inquiries are accepted.

Inspection 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.

Typical production: 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.
