Precision Power Presses: What 'Precision' Means in This Catalogue
'Precision' is used two checkable ways in this manufacturer's documentation, and this page keeps them separate. On the official website, precision is a published grade in the specification tables: GB (JIS) Class 1, stated for named series. In the manufacturer's platform catalogue, precision is a listing designation: a family of listings titled High Precision, attached to specific press types. A precision power press on this page is one that carries one of those two evidences — no model is promoted into the precision group by adjective.
The Official Evidence: GB (JIS) Class 1 Tables
- C1N C-frame mechanical press, 15-400 t — Class 1 stated in the published table.
- C1S C-frame deep throat press, 45-160 t — Class 1 stated.
- D1N straight side single crank, 80-260 t — Class 1 stated.
- M1N straight side single crank, 125-800 t — Class 1 stated.
- D2N — the table states GB/JIS precision without a class; the A1, S2N and T2N tables carry no precision-grade row. Those series are therefore not in this page's graded group, and their grade position is a quotation question, not a claim.
The Catalogue Evidence: High Precision Listings
The platform catalogue's High Precision titles map onto the same official series: a High Precision C-frame single crank mechanical press of 15-400 tons — the C1N's exact published span; two-point C-frame listings at 200, 250 and 300 tons; a high precision straight side double point listing; and listings naming the D2N and M1N series directly (H-frame high precision mechanical presses). A further listing joins the two evidences — a high precision punching press with high speed, for making motor lamination — pointing at the GP/GPH lamination branch on the lamination presses page. The GT knuckle joint series documents its precision behaviours on the official site: a die regrinding interval more than 25% longer than a conventional crank press and thermal compensation of the bottom dead centre — engineering evidence of a different, stated kind.
What Is Not Claimed
- No micron-level tolerance is published for the mechanical range beyond the class grades above, so none is quoted here; a tolerance for a specific model and die is a quotation figure.
- A High Precision listing title is the catalogue's designation for that listing — it is reported as such, and it does not upgrade the official table of the underlying series.
- Precision in production is a press-and-die outcome: the published grades describe the press; holding them in your parts is specified die by die in the enquiry.
The graded series carry their tables on the family pages — C-frame and H-frame — and the precision story across the plant, including inspection and testing, is on the quality page. The documented precision work is stated series by series, not as one route: lead frames on the knuckle joint page (GT series), terminals on the GS high-speed page, and motor laminations on the lamination pages (GP and GPH series).
Frequently Asked Questions
Which presses here carry a published precision grade?
GB (JIS) Class 1 is stated in the official tables of the C1N, C1S, D1N and M1N series. The D2N table states GB/JIS without a class; the A1, S2N and T2N tables carry no precision-grade row.
What does the catalogue's 'High Precision' designation cover?
A family of platform listings titled High Precision: C-frame single crank at 15-400 tons, two-point C-frame listings at 200-300 tons, a straight side double point listing, and listings naming the D2N and M1N series.
What tolerance will a precision press here hold?
The published evidence is the precision class in the series table; a part tolerance is a press-and-die figure and is confirmed model by model in the written quotation. No blanket micron figure is published, so none is claimed.
Are the high-speed presses precision machines?
The lamination branch is documented in precision terms — the GP/GPH series for thin electrical steel, and the GT knuckle joint page documents BDC thermal compensation and a die regrinding interval more than 25% longer than a conventional crank press.
