A buyer searching for Machine Vice is usually trying to stop a bad substitute. A CNC machine is specified by travels, spindle or process, accuracy, control, and the parts you will actually cut. The notes below are selection criteria for a Machine Vice. 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 Machine Vice
A CNC machine is specified by travels, spindle or process, accuracy, control, and the parts you will actually cut. For a Machine Vice, 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.
Machine Vice is easy to confuse with Oil Mist Collector. 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 Machine Vice |
|---|---|
| Utilities | Power, air, and foundation. |
| Travels | X, Y, Z, and any rotary, in the work envelope you need. |
| Process | Mill, turn, laser, plasma, or EDM, with power. |
| Accuracy | Positioning accuracy and repeatability, and the method. |
| Control | The control name and who can edit the program. |
| Tooling and table | Taper, table size, or the chuck. |
How to compare two offers
Lay both quotes for Machine Vice on one sheet and line up utilities, travels, and process. 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 Machine Vice with a cheaper line that omitted utilities.
Documents worth having before the deposit
Ask for an accuracy statement and a layout with service space. The file should name Machine Vice 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
- Ignoring the control your programmers know.
- Understating spindle power for the material.
- Buying travels that the fixture then consumes.
On a Machine Vice, 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: “Machine Vice — State travels, process and power, accuracy, control, and utilities.” 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 waterproof / IP65 belong
Searches often add a constraint to Machine Vice: waterproof / IP65, or IP67. Keep those on this page. 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. IP67 is dust-tight plus a defined temporary immersion. It is not a rating for living underwater, and it says nothing about sunlight or salt. 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 Machine Vice include?
State travels, process and power, accuracy, control, and utilities.
Is a cheaper Machine Vice the same part?
Only if utilities, travels, and the documents match. A missing line is a different offer.
Do waterproof, OEM, or IP words need their own page?
No. For Machine Vice they are extra lines on this specification. Ask for the test or the drawing that gives the word a value.
