When a business needs high-quality trimmed products completed in a short time, manually operated woodworking machines will not get the job done. A computer numerical control (CNC) router is a device that uses computer control to trim and cut numerous tough materials like wood, steel, aluminum, and plastics. The elevated precision delivered by these devices leads to increased productivity and will save a firm money on labor. A number of factors exist that all firms must take into account before purchasing new or used CNC routers.
Type of Motor
These devices can be powered by a servo motor or a stepper motor. A servo motor requires considerable maintenance and tuning, but do provide higher accuracy. Alternatively, a stepper motor will determine positions by counting steps, requires less maintenance, and is less expensive.
Router Bits
There are a number of different bits that can be used by these woodworking machines, but a company must make sure these bits are sharp at all times. Companies will usually buy different sized bits in groups, so that they will be able to handle different cutting jobs without needing to buy additional bits. Popular options include the less expensive standard bits with carbide tipping, or more expensive diamond-tipped or diamond-abrasive bits. Unlike standard bits, the more expensive options can be serviced several times before replacement is necessary. Standard bits might come with used CNC routers, but purchasing diamond-tipped or diamond-abrasive bits is a great way to prolong the effectiveness of these pre-owned devices.
Router Spindles
It is preferable for machines to have automatic changing capabilities, but some machines will have manual single-cutter spindles that need to be changed by hand following each cut.
Machine Size
The size of the machine will be determined based on the weight of the material to be cut. Heavier material will require larger woodworking machines.
Drive System
The type of drive system will affect the accuracy and precision of the material trim. To drive the system’s axes, a buyer can choose between lead screw, ball screw, or rack and pinion drive systems. The ball screw system is most expensive, because it allows woodworking machines to accomplish the most accurate cuts. The other two options are less expensive, but provide an inferior cut when the motor changes direction.
Benefits of Buying Used
With each of the options above, cheaper and more expensive options are mentioned. When a company orders new woodworking machines, they have the option of customizing the aspects above by paying premiums. Unfortunately, this adds uncertainty to the final price. When a company opts for used CNC routers, all options have already been chosen, so there will be no surprises or added costs. Buyers will have the option of obtaining a warranty from the seller, ensuring used CNC routers will be as reliable as new machinery.
RT Machine has both new and used CNC routers, enabling buyers to get a great deal on a pre-owned device, or customize a new machine when cost is not an issue.
