There is usually a surprisingly broad spread in the data normally provided by devices such as a durometer, a tool for measuring hardness. There are also a number of variables that can scatter the readings even more. These variables include operator technique, geometry of the test specimen, and even ambient temperature and humidity. To accommodate such variables, material specifications usually permit a tolerance of ±5 points on the scale of the measuring device. But sometimes even a 10-point spread is not enough to provide satisfactorily comparable readings on identical samples measured by technicians in different labs. 2d Shape Cutting Machine The best known device used for measuring hardness of elastomers and rubbers is the Shore A durometer. It is intended for use on materials as soft as a baby-bottle nipple or as hard as the heel of a shoe. It uses an indento...

CNC routers can operate with accuracy for long periods of time, but things inevitably wear out.

CNC routers can operate with accuracy for long periods of time, but things inevitably wear out. Check out the best online sources for CNC router parts to fix or upgrade your beloved machines. A computer numerical control (CNC) router is a computer-guided cutting machine used for cutting a wide variety of materials, such as wood, steel, aluminum, and plastic, among others. Routers can vary in size from large industrial machines of up to six meters long, filling an entire room, all the way down to desktop CNC routers that can operate beside your PC with a direct connection. For more information on available desktop and kit CNC routers, check out our guide on the best CNC router kits. But what happens when your router cutting tools wear out or you need different materials to produce your desired products? Then you’ll need a dedicated parts supplier. For a list of the best, read on! Some will be expected, but others will be new to many CNC router owners.
