The advantages of using CBN wheels for ferrous tool grindingGrinding is often the final operation that determines whether a cutting tool performs reliably or becomes a source of vibration, poor finish and premature…
Consistent edge radii on carbide insertsA carbide insert may be a small component, but its cutting edge has to withstand heavy machining loads without chipping or producing a surface that falls…
Geometry of chamfer cuts for threaded fastenersA chamfer on a threaded fastener is more than a cosmetic bevel. It can remove burrs, protect the first engaged thread, guide a nut, and establish how cleanly…
Measuring ROI for an automatic wheel truing systemThe return on investment for an automatic wheel truing system depends on more than its purchase price. A useful business case measures cycle-time savings,…
The causes and fixes for dimensional drift in overnight grinding runsDimensional drift is the gradual movement of a finished tool away from its first measured size. During an unattended shift, a grinder can appear to hold…
Integrating a Parts Washer Into Circular Knife SharpeningPrecision circular knives can be sharpened to micrometer-level accuracy, yet a contaminated cutting edge can still ruin the result. Swarf, oil, adhesive, dust…
How to Use a Tool Forming Grinder for Spherical End Mill ProductionA spherical end mill—often called a ball-nose cutter or radius cutter—has a cutting profile that blends continuously into a hemispherical tip. Producing that…
How Wheel Porosity Controls Coolant Flow in Deep GrindingDeep grinding places unusual demands on the abrasive wheel, coolant system and machine structure. As the contact zone becomes deeper, the wheel carries more…
Selecting collets and workholding for reliable micro grindingMicro grinding magnifies small setup errors because the cutter, wheel and workpiece are all part of the same accuracy chain. Radial play in a collet, a long…
How to optimise the grinding sequence for multi-step tool formingOptimising the grinding sequence for multi-step tool forming starts with a useful distinction: the shortest cycle is not automatically the best sequence. A…
