The Best Online Speeds and feeds calculator. For Milling, Turning, Drilling, Grooving, and Parting off. Results: Cutting conditions and Grades
Drilling machines with continuous speed change control are better than stepped or discrete speed change gear boxes for drilling stainless steel. When drilling deep holes, reduce the speed and feed as the drill moves into the metal.
Reduce speed and feed by 30% when reamed hole size comes out too big. With HSS drills always use a peck drill cycle. Make your peck depths a maximum of half your drill diameter. Example: 0.250 in drill diameter pecking at 0.125 depths. For extra long drills reduce speeds and feeds by 30%-50%.
For general Turning of Stainless Steel 304 at stable conditions use a grade with a Semi Hard substrate and CVD coating. In case you are running at a cutting speed that is lower than 390 SFM (120 m/min), it is better to use a grade with a Semi Hard substrate and PVD coating.
The Speeds and Feeds Calculator may be employed for calculations of estimated speeds and feeds (RPM and IPM) values on the basis of the parameters you have currently set based on your tools and stock material. How to use this calculator: Choose a type of operation (drilling, reaming, boring, counterboring, face milling, slab milling/side ...
First choice for machining steel, cast iron, and short chipping materials. Suitable for severe cutting conditions. First choice for stainless steel. Suitable for deep drilling and operations where low power consumption is required.
You’ve found our simple free online Drilling Speeds and Feeds Calculator that uses the classic cutting speed formulas taught in shop class for things like surface speed to rpm. With a calculator, you don’t need to worry about how to calculate spindle speed or feed rate.
