A small, precision milling machine for prototyping circuit boards. It can also be used for engraving of faceplates and other items if the proper bits are used. This unit was made in approximately 1999 by the German company LPKF Laser & Electronics AG. It uses standard 1/8" shank bits, 38mm for cutting the board and 36mm for cutting and milling the copper. The 38mm length is pretty standard, but the 36mm bits are more specialized.
Before using this machine, you must meet with someone who is experienced in using it. The bits are expensive and easily broken, and you must be careful when using the machine as there is a risk of injury if it is not used safely.
