Select the material, condition and finished dimensions. Check the published process scope, then carry the details into an inquiry.
This check does not confirm a price, stock availability, production slot or accepted order. The drawing and quotation define the supply scope.
Browse the Product Catalog
Browse 30 tool steel grade and finish options. Review material conditions and directional tolerances before carrying a selected model reference into your inquiry.
Choose the Finish for Your Next Operation
Specify the finished tool steel plate your next machining or assembly operation requires. Choose two-side grinding with four-side milling, eligible E1 six-side precision grinding, or six-side precision milling. The number of ground faces, material condition and directional tolerances form part of the order specification.
Check a plate specification or prepare a plate inquiry with your drawing, quantity and destination.
Use the milled vs ground plate guide to match finished faces and directional tolerances to your next operation.
Custom Plates and Precision Ground Flat Stock
Precision ground flat stock may be offered in standard bar or plate dimensions. A drawing-specific plate requires its own finished dimensions, steel grade, material condition and face-finish requirements. Lichengda supplies processed plates and blocks to the agreed specification.
UK suppliers may also describe ground flat stock as gauge plate. This purchasing term does not identify a single steel grade or establish the material condition and finished faces. For a custom plate inquiry, specify your required grade and compare the corresponding grade and finish options.
If your purchasing specification uses ground flat stock, identify which faces must be ground and whether the ordered dimensions are the finished blank size or include allowance for later operations. A ground-finish description alone does not specify six ground faces, hardness, flatness or surface roughness.
Review the flat-stock and custom-plate distinction and choose a plate model as the starting point for a drawing-specific inquiry.
Prepared Plates for Your Next Machining Operation
Outsourcing the specified plate preparation can reduce the cutting, squaring, milling or grinding work that remains with your own shop. The benefit depends on exactly which faces and dimensions are supplied finished.
Use the finish comparison and selection worksheet to define the work you want completed. Final machining features, roughing allowances and inspection requirements belong in the quotation; a prepared plate does not automatically include a finished cavity or complete tool.
Precision ground steel blocks are also available for drawing-specific review. Specify the grade, material condition and finished faces; block dimensions do not by themselves establish E1 eligibility. P20 steel plates can be reviewed for milling or two-side grinding, with the delivery condition and tolerance scope agreed for the order.
Two-Side Ground, Four-Side Milled Tool Steel Plates
The two thickness reference faces are ground; the other four faces are milled. Thickness tolerance is ±0.05 mm. Length and width tolerances are ±0.10 mm. Parallelism between the two ground reference faces is 0.04 mm per 100 mm.
Use the drawing to identify the ground faces and any additional surface or geometric requirements. See the full comparison.
Review two-side ground + four-side milled specifications and grade options.
E1 Six-Side Precision Ground Tool Steel Plates
All six faces are precision ground. Eligible orders have length, width and thickness tolerances of ±0.02 mm and parallelism of 0.02 mm per 100 mm. E1 applies only to the specified steel grades and conditions, with length and width each up to 600 mm and thickness 10–200 mm.
Check eligible materials and conditions before selecting E1. Larger blocks, annealed material and other grades are reviewed to separately agreed tolerances.

Six-Side Precision Milled Tool Steel Plates
All six faces are precision milled. Length, width and thickness tolerances are ±0.10 mm, with parallelism of 0.08 mm per 100 mm. This finish prepares plates and blocks to the agreed dimensions for subsequent machining.
Specify the material grade, delivery condition, finished dimensions and any remaining machining allowance. Compare all directional tolerances.

Tolerances
| Finish | Length | Width | Thickness | Parallelism |
|---|---|---|---|---|
| Six-side precision milling | ±0.10 mm | ±0.10 mm | ±0.10 mm | 0.08 mm per 100 mm |
| Two-side grinding + four-side milling | ±0.10 mm | ±0.10 mm | ±0.05 mm | 0.04 mm per 100 mm between the two ground reference faces |
| E1 six-side precision grinding | ±0.02 mm | ±0.02 mm | ±0.02 mm | 0.02 mm per 100 mm, subject to the E1 eligibility below |
Parallelism values are stated per 100 mm. They are not interchangeable with flatness or surface roughness, and are not a single whole-plate tolerance. Show any additional geometric or surface requirements on the drawing.
E1 Eligibility
Six-side precision grinding (E1): length, width and thickness tolerances of ±0.02 mm, with parallelism of 0.02 mm per 100 mm. This specification applies only to blocks with length and width each up to 600 mm and thickness from 10 to 200 mm, in the following grades and conditions: pre-hardened 718H, 1.2738, NAK80 and 1.2316; or hardened and tempered S136, D2, SKD11 and DC53. Larger sizes, annealed material and other grades are subject to separately confirmed tolerances.
E1 is Lichengda’s designation for this six-side grinding specification. Annealed stock and large H13 hot-work forgings are not automatically eligible for E1; their machining and tolerance requirements are reviewed separately.
Sizes
Regular plate sizes range from 100 × 100 × 20 mm to 800 × 600 × 300 mm. Maximum processing size is 1,200 × 800 × 400 mm, subject to grade, condition and finish review.
The E1 eligibility envelope is separate: length and width each up to 600 mm, with thickness 10–200 mm. The maximum processing size does not carry the E1 precision specification.

Grade names are listed separately and do not imply automatic equivalence or substitution. Annealed, pre-hardened, or hardened and tempered conditions are supplied according to the actual grade and order requirements.
For example, requests for NAK80 precision ground plates are reviewed against the pre-hardened E1 requirements. Requests for D2 precision ground tool steel plates are reviewed against the hardened-and-tempered E1 requirements. The same E1 size limits and inspection requirements apply; not every grade or condition is E1-eligible.
We supply processed plates and blocks to the agreed specification. Include the grade, condition and processing requirements in your inquiry.
Compare the finishing routes for your specified steel grade. Each link opens the matching grade and material-condition row, with a model-specific inquiry option.
E1 options require the condition shown, length and width each ≤600 mm, and thickness 10–200 mm. Dimensions and drawing review still apply. For milling and two-side grinding, confirm the material condition for the order. Grade designations do not imply equivalence or substitution; these options are made to specification, with availability confirmed in the quotation.
Reports and Production Lead Time
MTC material documentation, hardness reports and dimensional inspection reports can be provided. UT reports are available on request. Agree the required documents and inspection scope when ordering.
Typical production lead time is 3–7 working days. Production lead times are quoted in working days, excluding weekends and statutory public holidays in China. Lead time starts on the next working day after all applicable conditions have been fulfilled: receipt of the formal purchase order, final drawing/specification approval, and receipt of the deposit where required. Transportation time is separate.
