Two-Side Ground, Four-Side Milled Steel Plates

Two Ground Reference Faces

This finishing route grinds the two faces that establish plate thickness and mills the four remaining side faces. It is a distinct supply option from both six-side milling and six-side grinding. State which faces serve as datums and whether the delivered dimensions include allowance for later machining.

Use this route when ground thickness faces and the published thickness relationship match the next operation, while milled side faces meet the drawing requirements. If a side face, pocket or bore needs a different tolerance, identify it separately rather than extending the thickness specification to every feature.

Directional Tolerances

Thickness tolerance applies between the ground faces. Length and width remain milled dimensions. Flatness, perpendicularity, whole-plate geometry and surface roughness requirements need their own definition where applicable.

Grade and Model Options

The following eleven grade options use the two-ground/four-milled finishing scope. The material condition is confirmed for the order; similar grade names are not automatic substitutes. Choose a reference to carry the grade and finish into an inquiry.

Catalog references identify grade/finish scope. Dimensions, material records and acceptance follow the approved order. Schematics illustrate the model option; a general photograph does not establish a specific grade or tolerance.

Dimensions and Material Condition

Regular plate dimensions range from 100×100×20 to 800×600×300 mm. Maximum processing capacity is 1200×800×400 mm, subject to review of grade, condition, geometry and inspection requirements. Processing capacity alone does not confirm every combination of dimensions and tolerances.

State annealed, pre-hardened or hardened and tempered condition as required for the selected grade. Identify later machining and heat treatment so the supplied size, allowance and acceptance stage are clear. Do not treat machining allowance as an alternative expression of the delivered tolerance.

Inspection and Production

MTC material documentation, hardness and dimensional reports can be provided; UT is available on request with an agreed scope. Identify the report coverage and inspection method before ordering. Record the two ground reference faces and the dimensions to be checked.

Typical production is 3–7 working days. Working days exclude weekends and statutory public holidays in China. Production starts on the next working day after formal PO receipt, final drawing/specification approval and applicable deposit receipt are complete. Transport time is separate.

Prepare a Two-Side-Ground Plate Inquiry

Send the grade, delivery condition, finished length/width/thickness, quantity, datum faces and any additional geometric or surface requirements. PDF, STEP and DWG files can be attached in your email app when sending to stella@lichengdaheating.com.

Prepare an inquiry with this finish selected, compare the full plate range or read the milled-versus-ground buying guide.
