What is minimum torque required for CNC stepper motors and ...
$\begingroup$ The real thrust of my answer is that a simple google search for "milling torque formula" or "milling torque calculator" will answer this question. The question is too vague (as to the desired type of milling) to cite a specific formula. $\endgroup$ – Ian Nov 11 '16 at 13:08

Milling head or CNC router spindle for cutting aluminum?
Milling aluminum (6061) doesn't require nearly as much torque as milling steel but more torque is usually better than less. The higher the spindle speed, the more power you need to maintain decent torque. This is why large high speed CNC mills have crazy huge 40hp spindle motors (or more). Take a look at the Hass mini mills for an example.
Milling Horsepower Calculator - CustomPart.Net
The horsepower at both the spindle and the motor are shown, as well as the spindle torque for a given spindle speed (RPM). The motor horsepower required for the milling operation can then be compared to the horsepower capability of the machine. Learn more about Milling.
stepper motor - How much torque do I need for a CNC machine ...
"It is recommended that you get approximately 13.7 N-cm (= 0.137 N-m or 1400 gf-cm or 19.4 ozf-in or 1.21 lbf-in) of holding torque (or more) for RepRap axis motors to avoid issues, although one stepper with less has been used successfully.
Torque and linear motion formula - Build Your CNC
The next thing to consider is the properties of the machine, because you will need this information in the formula. Ok, so let's give it a try: To determine torque, lets gather some information. By the way, we are talking about torque during a continual turning motion, not at a holding position.

Attacking Aluminum: A Machining Guide - In The Loupe
Apr 24, 2018 · Aluminum is one of the most commonly machined materials, with most forms featuring excellent machinability. Since it is a commonly used material in manufacturing, the competition for aluminum manufacturing can be intense. Learn how to stay ahead of the competition with our helpful guide to Aluminum machining.
rpm and feed rate for aluminum - Practical Machinist
Mar 02, 2005 · 2. Feed rate is something that you can look at any book, but it won't tell you enough. If you're using a HSS end mill, do you have regular or high helix? If you have a regular helix end mill, you can usually get .001" per tooth with aluminum (maybe more, that's conservative). So, .001*4*2000=8 in/min. This is a starting place. 3.
Torque Needed For Milling Luminum
Torque Needed For Milling Luminum. Feb 09, 2007 At work we run aluminum at very high R.P.M. I've run big diameter parts at two thousand feet per minute, which is actually a slow R.P.M. due to the diameter and on the next machine run a small end mill at the machines maximum R.P.M. of 12,000.
Drilling 7075 aluminum - high speed or high torque? - Page 1 ...
7075 is a hard aircraft grade aluminum containing zinc. Machines rather well, and is less prone to built up edge (less gummy) than say 5000 series aluminum. Be sure you use some type of coolant or oil. WD40 does a nice job on aluminum. The old Ivory liquid dish soap was the trick on aluminum back in the day due to the fatty ester content.
a torque wrench to achieve proper bolt loading. While the head bolts are being torqued to the specified value, the technician can use the TRQ-1 tool to accurately measure the degrees of additional rotation required. This eliminates guesswork and assures more consistent results. Torque-To-Angle Indicator (Part Number TRQ-1) Head Bolts

Understanding tangential cutting force when milling | Cutting ...
May 01, 2012 · When the required machining power value is about the same as the milling machine’s rated power, milling productivity approaches its maximum. Torque (T s ) that is applied to the spindle, and therefore to the milling cutter , is generated by the tangential cutting force (F t ) and can be calculated by the formula:
