Gunsmithing Powerfeed on a milling machine

Re: Powerfeed on a milling machine

got ya.... definatly dont need to pay extra for that feature at the moment... thanks

next question
is this feature worth an extra 775 on top of a base of 2500

2 HP VFD and Motor $775.00 Installed
This option allows you to run your spindle from 50 RPM to 3600 RPM. Couple this with
coolant and you can run feeds 125% faster than our standard 1750 RPM 2 HP motor.
Spindle RPM and Spindle Start and Stop are all controlled in the Gcode. You can also run the Spindle off the keyboard which is great for manual milling and rigid tapping.

If you’re doing rifle work, the power feed won’t be necessary. I certainly wouldn’t pay $775.00 for it. All of my cuts are made manually and I use the mill mainly for stock work.

"2 HP VFD and Motor $775.00 Installed"

Checked out their site, and it looks like it is an upgrade to a variable frequency drive.
That is worth the price.
Having rpm in program is better than having to remember what you did last time and adjust.

I would also go with the nt-30 spindle option too.
If you need help with tooling, or programing, let me know.
For hobby/personal work, I would go with a vortex chiller, or mql system, instead of coolant. (much cleaner, and cheaper in the long run.)
Don't understand why power feed is an option on a cnc.

Good luck!

Re: Powerfeed on a milling machine

My favorite manual is an old belt head Bridgeport.
Dials, not digitals.
Doing by hand lets you now how it feels to cut.
Do you know, and understand Backlash?
Changing belts will be second nature.
R-8 will be fine.

Can you fix worn tooling?

Electroless nickle is easy.

Re: Powerfeed on a milling machine

TCA4570 the BIGGEST problem with that route for a new to machining person is lacking the experience to know a clapped out POS with bad bearings and a table someone took a die grinder to vs one with chrome ways that got used gently in a tool room somewhere. That and the pita of 3 phase power and the lack there of in a resedence.
 
Re: Powerfeed on a milling machine

I would strongly consider a good used knee table mill like a bridgeport if I were you. I havent used a mill of the type that you are looking that had a table that moved smoothly, they all are very stiff and are very tiring to use. Those mills are also a pain if you need more headspace, you have to rezero if you need more or less space than the verticle spindle travel will allow.

I would look at a machine like this

Variable speed is an option that is also very valuable to have.
 
Re: Powerfeed on a milling machine

He is looking at a NEW manual, small mill, with box ways.
It has a 2 hp single Phase motor, on it.
All he has to do is plug it in and start playing.

Anything you can use is better than a dream!

Do you fix your Bridgeports, or bitch about them?

Chrome is best cut with diamond burr at point of flaking.

Basic Maintnance is easy!
Lack of is costly!
