Buying a CNC Lathe & CNC Mill - Need Advice

[lynnl]

In all of the discussions, have you considered metal removal rates? Time consumed by tool and part changes?
You are trying to create a business venture with a real product. Can the machines you've chosen produce your product in a reasonable amount of time to turn a profit?

HA! ...are you kidding? He hasn't considered anything, except "...I want a CNC."
Removal rates..? Tool/part changes...? Mere trivialities; we'll deal with that later.

This whole thread has read like something out of a fantasy land. Certainly entertaining.

Had he just said, "I just want a desktop CNC machine to play around with, and a 4th axis to go along with it", this thread would of been much smaller and far less controversial.

No, because it's for prototyping not mass manufacture.

Also it's for learning machining as a skill.

"Unfortunately I don't have the luxury of time.
I have to get caught up in a hurry and start making parts.
I'm going to have to learn this by doing."

So after umpteen prototypes, plus all the scrapped parts, the final design will be manufactured elsewhere?

High value, low volume.

The value being on the electronics side which is highly complex.

Well, please post about your adventure on here, and I will offer help when ever I can.

4 in. CNC Vise

What is a CNC vise?

What is a CNC vise?

Its a regular vise at twice the cost...

I commented a while ago, as no one else has said it, but your tooling cost is going to be roughly the same as what you spend on the machine too.

Cheap import tool holders $20-30 CAD each
Cheap import endmills $5-10 each
Decent drill bits $3-10 each

Then you are also gonna want to look at parallels, vises, t-slot clamps, calipers, dial indicators, setup blocks, etc....

Is Pidgen English you native tongue?
Or is mocking Asians that have difficulty with the English language good sport?
I guess you don't see this constant mockery as racism?

So I guess if I buy a cheap vise, and true it up on my surface grinder, it becomes a CNC vise? Better yet, get two cheap vises, true them up to each other on the surface grinder, they become extra expensive CNC vises!

Because manual hex keys simply will not work.

Do they come in freedom units or are CNC hex keys only available in metric?

Before using a CNC hex key one must enter the code for the unit of measure required, either G20 or G21.
You really should have known this.
