A laminate trimmer (or trimming router) is a small version of a wood router, normally used to trim laminate such as Formica. It generally has a 1/4-inch collet. Typical laminate trimmers spin their bits at up to 30,000 RPM. Some models provide variable speed control.
An important application devised in the 1920s was the use of phenolic laminate fabric for gears; cut on conventional hobbing machines, the gears were tough and quiet, which was important for automotive timing gears. By 1932, the Formica Insulation Company was producing 6,000 gear blanks per day for Chevrolet and other car makers.
The term abrasive jet refers specifically to the use of a mixture of water and an abrasive to cut hard materials such as metal, stone or glass, while the terms pure waterjet and water-only cutting refer to waterjet cutting without the use of added abrasives, often used for softer materials such as wood or rubber.
The booming popularity of countertops made of engineered stone has driven a new epidemic of silicosis, an incurable lung disease, researchers have found. California workers who cut countertops are ...
Steel cut-off saw for workshop use Cutting heavy steel cable with a Husqvarna freehand saw US Navy diver preparing to use an abrasive saw for underwater salvage. An abrasive saw, also known as a cut-off saw or chop saw, is a circular saw (a kind of power tool) which is typically used to cut hard materials, such as metals, tile, and concrete.
A rail repair dutchman is typically a 4–6-inch (100–150 mm) long piece of rail that is cut in advance for the purpose and carried by a section crew. If the gang finds a rail with a chipped or broken end, they remove the connector plates ( fishplates ), cut out the damaged section, replace it with the dutchman, and bolt the connectors back ...
CNC routers can perform the tasks of many carpentry shop machines such as the panel saw, the spindle moulder, and the boring machine. They can also cut joinery such as mortises and tenons. A CNC router is very similar in concept to a CNC milling machine. Instead of routing by hand, tool paths are controlled via computer numerical control.
Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].
