Some machining of copper alloys is done dry, but the use of a cutting fluid invariably increases the level of possible speed and feed,

Five different brass rod alloys readily maintained the high-speed machining parameters shown below on a V55 Makino CNC Machining Center with a 20,000 RPM 

Cutting Speed = 75 (fpm) Diameter of Cutter = 0.38 for a 0.38 drill. One-third the speed for countersinking would be = 789/ 3 = 263 RPM. Center Drill RPM Calculations. A center drill or combination drill and countersink (Figure 6) is used for spotting holes in workpieces or for making center holes for turning work.

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 milling, end milling, or turning), select

Copper Milling Cutter Home » Copper Milling Cutter This tool series with extraordinary sharpness, best suited for high-precision machining of copper and copper alloys. It is a special angle design, the products after finished have a high degree of smoothness, so they can use for mirror processing.

Feed Control (Milling) - Customize how the Feeds and Speeds Calculator fine-tunes the Chip Load and Table Feed. Stage 1 - The system calculates the desired maximum chip load according to the cutter type, diameter and raw material. You have the below options to control how the chip load is calculated.

Cutting Speeds ; Free Machining Brass, 90–105, 180–200 ; Other Brass & Bronze, 60–75, 150–165 ; Copper & Phosphor Bronze, 30–35, 60–65 ; Wood & Plastic, 60–150, 150 

Determine the spindle speed (RPM) and feed rate (IPM) for a milling operation, as well as the cut time for a given cut length. Milling operations remove material by feeding a workpiece into

Pure copper is difficult to machine on 5 axis because of its high ductility and high cold workability. Tool wear is very high and chip formation very poor. As chip compression is substantial, the cutting edge is subjected to large mechanical loads. The long tubular chips that form when pure copper is machined are difficult to handle and remove.

For milling pure copper, it is recommended to use a ⅛” (0.125”) 2-flute carbide end mill with 3000 - 5000 RPM and a maximum feed rate of 10 

The cutting forces that occur when cnc machining pure copper are very high, especially at low cutting speeds 

1/16 · To determine this (you might need to break out the calculator), simply multiply the recommended cutting speed by the value 3.82 (round up to 4), and then divide by the tool diameter. For example, the ridiculously priced All Season 235/55R19 tires are a smidge over 29 inches in diameter, so that would mean (3.82 x 1320 SFM)/29.2 = 173 rpm.
