CNC Router Machines: Capabilities Should Match Production Desires

A CNC device is a piece of equipment instructed by means of computer generated code. Routers are capable of performing cutting or shaping movements at a faster rate than hand crafting. These machines may be manually operated; however, computer technology advancements have increased the accuracy and production rates of this equipment. You can employ CNC router machines in your woodworking processes to streamline production loads, cut costs, and create enhanced product or piece designs. Routers have a multitude of parts designed to work in unison for consistent and speedy piece completion. These machines may be fairly expensive when purchased new, but you can obtain a high quality machine in used condition to have a lower initial investment.

Used CNC Machine: Available Router Design Options

A used CNC machine has the same standard parts for operation as new machinery. Typical components include the controller, work table, drive system, spindles, tooling, vacuum, and safety items. The controller consists of all devices used to facilitate cutting movements. You may obtain either a proprietary or open-architecture controller when buying a routing machine. Feature considerations can include the type of display, amount of program storage, axis compensation, pre-set parameter capabilities, accepted file types, and custom tooling needs. Certain controller designs can make cuts without custom tools by using the ones already provided. This capability may drastically cut down the cost of purchasing additional parts for unique production or cutting processes.

You will also have a variety of work tables to choose from when making this purchase. Flat tables made with an aluminum or laminate surface cover are common with entry level devices. A T-slot table may be applied to wood pieces when made with an aluminum extrusion. Many companies use this design to build economical tables or for sign making. Pod and rail designs make a good choice when your will be working with flat pieces of wood where the edge will need to be easily accessible. Universal vacuum or nested tables perform cutting on full material sheets. The edge will be minimally accessible; however, vertical accuracy is very reliable. Fixtures are a must when the used CNC machine is applied to small pieces or warped parts. Matrix tables mix features of both vacuum and pod designs consisting of permanent grooves in the surface.

Stepper motor models track movements by means of steps with an open loop method. They do not receive additional information such as when the production piece is completed. Drawbacks of these motors include possible inaccuracies, reduced speed, and less torque than other types. Servo motors operate on a closed loop with an encoder offering constant feedback for position adjustments. DC models use a permanent magnet, round wire rotor, carbon brushes, and a feedback sensor to perform rotations. AC versions do not include the wired rotor or brushes and were created to remove the lag error problems associated with DC models. Numerous choices must be made regarding both the implementation environment and the type of CNC router machines. RT Machine professionals can help you with these decisions to ensure you are getting the equipment necessary for proper piece completion.
