Machine Tool Specification
Machine Tool Specification
(OP)
Hello,
We are thinking about purchasing a new CNC machine for which a machine specification document is to be prepared. I have never done one before. Is there a sample or a resource I can refer to as a guide which will help me prepare one. Thanks!

RE: Machine Tool Specification
Then I would do a search and get literature from all the machines that looked close. Go through and see which features you want. Then go to practical machinist.com and ask for opinions.
You will be taking notes during all this and the final set of opinions will be your specification list.
Then see whose machines match best, find out who has those machines and ask them what they think.
(Remember with a CNC machine you need a machinist and a CNC operator. They can be the same person but they are two different sets of skills and you really do need both.)
When you are done arrange your notes and you will have your form.

That's pretty much what I meant to say. Thanks for clearing that up.
Happy 4th,

1-Table size: Should adaquete to fixture dimensions that you want assamble.
2-Spindle taper. Hsk type spindles will give you high presicion on run out and high turning speed but they are not strong enough against a collusion as SK types. It is a questıon of is your process requires high speed or high power?
3-Coolant system. What is the minimum size of the internal coolant hole that you have in the middle of your tools. What is minimum pressure for that tool? Usually it should be at least 70 bars.
4-Vertical or Horizontal? big question Small parts, mqss production and 4th axis requirement signs horizontal. Big parts, big table requirement means vertical
5- machine accuracy? what is your part requirement as a tolerance? Or Consider the capability study.
6-Spare parts. What is the max time during a break down? Is it easy to find spare parts and service?
