A buyer searching for Press Brake is usually trying to stop a bad substitute. A machine tool or production machine is specified by the work envelope, the accuracy, the power, and the duty cycle. The notes below are selection criteria for a Press Brake. They are not a catalog promise. Confirm every rating on the current datasheet, drawing, or test report for the revision you will receive.
What has to be true of Press Brake
A machine tool or production machine is specified by the work envelope, the accuracy, the power, and the duty cycle. For a Press Brake, start from the duty, then the interface to the rest of the machine or the room, then the document that proves the claim. A lower price that leaves one of those blank is a different product.
Press Brake is easy to confuse with Roots Blower. If the quote could be read as either, add the line that separates them: the rating, the fitment, or the standard named below. Link the drawing number to that line so receiving inspection can reject the wrong one.
Numbers that change the quote
| Line | What to write for Press Brake |
|---|---|
| Capacity | The largest part or cut the machine is being bought to make. |
| Accuracy | Positioning or machining tolerance, and how it is measured. |
| Power and axes | Spindle or drive power, and the number of axes if it is a machine tool. |
| Control | The controller family and who can service the program. |
| Utilities | Electrical supply, air, and foundation or floor load. |
| Safety | Guards and the declaration for the machinery rules that apply. |
How to compare two offers
Lay both quotes for Press Brake on one sheet and line up capacity, accuracy, and power and axes. If a cell is empty, the offer is not finished. Ask for the missing line in writing. When those match, the honest difference is lead time, the test evidence, and who carries the warranty. Do not average a fully specified Press Brake with a cheaper line that omitted capacity.
Documents worth having before the deposit
Ask for a layout drawing with service clearances before the machine is shipped. The file should name Press Brake and the revision, not only the supplier’s homepage. A factory quality certificate such as ISO 9001 can sit beside that file. It does not replace it.
Failures that show up after delivery
- Leaving accuracy undefined so two quotes cannot be compared.
- Buying travels that the workholding then eats.
- Ignoring foundation and incoming power until the crate arrives.
On a Press Brake, the expensive version of the first mistake is discovering it after the goods are in the crate. Put the rejection condition in the purchase order while the supplier can still restate the offer.
A worked RFQ line
Use this shape, then replace the brackets with your duty: “Press Brake — State capacity, accuracy, power, utilities, and the control.” That sentence is a template, not a rating of any brand. If a supplier’s datasheet uses different units, convert them onto this sheet so the next offer can be compared.
Where words like stainless / corrosion belong
Searches often add a constraint to Press Brake: stainless / corrosion, or waterproof / IP65. Keep those on this page. Name the alloy or the coating and the chemical it must survive. Stainless is a family, not a guarantee. IP65 in IEC 60529 means dust-tight and protected against water jets. Write that code if hoses are the real exposure. The word waterproof alone does not name a test. If you need a third constraint, add it as another line on the same drawing. A second URL that only swaps the adjective does not give a buyer a second fact.

Questions buyers actually ask
What should an RFQ for Press Brake include?
State capacity, accuracy, power, utilities, and the control.
Is a cheaper Press Brake the same part?
Only if capacity, accuracy, and the documents match. A missing line is a different offer.
Do waterproof, OEM, or IP words need their own page?
No. For Press Brake they are extra lines on this specification. Ask for the test or the drawing that gives the word a value.
