There are some sellers who would sell a machine in much higher price, negotiate and try to get it for the actual or reasonable price. Before buying anything, make sure to do all research possible. The internet is a great way to check and compare prices, brand performance and customer feedbacks. You could check company sites and other businesses if they are selling their older models. It also needs to be retaught each time there is a new tool introduced. Versatile sizes and functions Today s CNC lathes are available in many sizes and are made by specialty manufacturers of sophisticated machinery. The most common CNC lathe has a tool turret that can hold tooling (insert cutters, drills, reamers) and a spindle with a chuck jaw to hold different types of metal. The works The ShopBot is a cutter (which looks like a drill bit) that can move in all three axes, making 3D movements and cutting all kinds of shapes ad patterns on such materials as wood, plastic, foam, aluminum and others. The ShopBot CNC cuts materials like a saw on the X or Y direction and on any diagonal. Specialty routers There are also CNC routers which are dedicated on special designs, they are called specialty CNC routers. Samples of specialty routers are engraving machines, 3D engraving machines and PCB routers. The PCB router is used to create circuit boards. Several CNC features would include having separate heads. Other important components The CNC linear drive system includes the motor, the linear bearing system, and the lead screw assembly. Every axis uses linear drive system that drives their particular spindles. The motor links the mechanics and the electronics of the system. There are two types of motors in CNC wood router machines the stepper and the servo motors. Also check your computer s operating system, memory, hard drive space and other important specifications. Make sure that you computer would be supporting the program/ software, the least you want is your system breaking down on an important and crucial occasion. Aside from the actual software for CNC training, there is also a simulation software which could be used while training operators.
