Category Definition<br />
Our extensive offering of stock diamond and cBN electroplated products has been<br />
engineered to meet the diverse demands of traditional and emerging tool and die,<br />
ceramic, and composite applications.<br />
Applications:<br />

dies and molds, routing, reaming, blending radii, notching and cutting-off with<br />
saw blades in ceramic, tool and die, and composite applications<br />
Mounted points, mandrels, drills, routers, contour tools, wheels, files, and<br />
saw blades<br />
Diamond and cBN (cubic Boron Nitride)<br />
Abrasive Applications<br />
Although diamond and cBN (cubic Boron Nitride) are both superabrasives, the use of diamond and cBN varies, depending upon the materials<br />
to be ground.<br />
Diamond Grinds:<br />
• Cemented carbide<br />
• Glass<br />
• Ceramics<br />
• Fiberglass<br />
• Plastics<br />
• Composites<br />
• <strong>Abrasives</strong><br />
• Stone<br />
• Electronic components and materials<br />
cBN Grinds:<br />
• High-speed tool steels<br />
• Die steel<br />
• Hardened carbon steels<br />
• Hardened stainless steels<br />
• Alloy steels<br />
• Aerospace alloys<br />
• Abrasion-resistant ferrous<br />
materials<br />
In general, cBN is used to grind ferrous materials. Diamond is used to grind non-ferrous materials, because of an adverse reaction between<br />
diamond and iron.<br />
Coolants<br />
Although coolants may not<br />
be necessary, using a<br />
coolant produces superior<br />
surface finishes, a longer<br />
tool life, higher<br />
performance, and reduces<br />
tool loading.<br />
Feeds<br />
Suggested feeds for jig or<br />
internal grinding are from<br />
.0002" – .0004" per pass.<br />
Speeds<br />
Maximum Operating Speeds (MOS)<br />
Never exceed the maximum operating speed marked on the superabrasive product being used.<br />
Electroplated Products: 25,000 SFPM<br />
Maximum speeds of mounted points are a function of the length of overhang and size of the product.<br />
Refer to “Safe Operating Speeds” in form #2872, provided with your product.<br />
Recommended Operating Speeds<br />
The preceding speed is the maximum safe speed and not necessarily the most efficient. Superabrasive<br />
products operate most effectively at speeds lower than the maximum. The following are general<br />
recommendations. cBN products, in many cases, are used effectively at higher speeds.<br />
Electroplated Diamond Products: 5,000 to 10,000 SFPM<br />
Electroplated cBN Products: 8,000 to 10,000 SFPM<br />
Calculating Operating Speed<br />
The following formula may be used to quickly calculate wheel speed: RPM = Revolutions Per Minute<br />
sfPM = Surface Feet Per Minute<br />
To convert SFPM to RPM: (Multiply SFPM x 3.82) divided by wheel diameter in inches<br />
