Adding copper to tungsten results in a material that is heat-resistant, electrically conductive, and easier to machine. This makes these Tungsten Alloys a good choice for electrical contacts. There are various standards for Tungsten Alloys such as ASTM-B-777 and AMS-T-21014 .

The astounding high-speed machining capabilities of brass create unbeatable manufacturing economics in the highly competitive market for precision parts.

Given the diameter of the tool and the surface speed, the RPMs of the spindle can be calculated. Then if the tooth load for the cutter is know, and the number of teeth, the feed rate can be determined. Units: English Copper: 0.004 - 0.008: Cast Iron (soft) 0.004 - 0.008: Cast Iron (hard) 0.002 - 0.006: Mild Steel: 0.002 - 0.010: Cast Steel

spindle spindle speeder 30000 rpm | HP-H. Increases tooling RPMs 5 times. Maximum 30,000 min-1 models available. Assures low noise and vibration by precision ground steel gears. Tool shanks as small as 0.5mm (0.02in) (FDC 07 series), up to 12mm (0.472in) (FDC 12 series) can

Choose the proper chip load factor (CLF) based on the radial depth of cut. Now choose the right surface feet per minute (SFM) or surface meters per minute (SMM) Use the SFM and the diameter of the mill to calculate the RPM of your machine. Use the RPM, IPT, CLF and the number of flutes to calculate the feed rate or IPM.

Note: This article is Lesson 9 from our Free Feeds and Speeds Master Class. Introduction to Twist Drills and Chip Formation. The lowly twist drill is one of the most commonly used tools in the machinist’s arsenal. By all accounts, it also has some of the highest material removal rates of any of the tooling available. As such, it’s worth getting to know them a little better.

Recommended RPM range is 1070 - 2292 RPM At the speed of 1681 RPM, the recommended feed rate is 235340.00 - 504300.00 IPM Interpreting Results: - The maximum feed for roughing is the high rate - The starting feed for the best finish is the low rate - The starting feed for roughing should be taken from the middle of the feed range Formulas
