CNC router tables are an expensive investment not only in your router machine, but in your woodworking as well. First reaction was to inquire an average price for the new machine he is about to purchase. When he finally replied that he wants to spend between $1000 and $1500 including peripherals, felt like he was in for an even bigger shock. Second reaction: “What do you mean by peripherals?” Third reaction: “That’s impossible, how can you possibly afford that much?”
If you have built a woodworking shop before or if this is your first woodworking project, it is very possible that you already own some CNC router table supplies. If not, then you should start looking for them now. In order to make sure that you don’t run into problems when trying to source your own supplies, there are some things to keep in mind. This article will focus on the types of wood and other materials to look for as well as the different wood types available.
First off, there are four main types of cnc router tables: those made out of steel, those made of acrylic, those made from cnc steel and those that are vacuum pump driven. There is also the ‘upright’ style, ‘low center’ style, the ‘high center’ style and also the zero center type. All four of these types have different features. For the purposes of this article, we’ll concentrate on the vacuum pump powered models because they are the most common.
Vacuum pump-driven CNC router tables are usually powered by one of two methods: either via a 12 V battery or via a small (or large) air compressor. One of the major advantages of these tables is that they typically come with rubber tipped rubber feet that prevent damage to the table top while still allowing it to be touched. This can also be extremely convenient because not only does it allow one to lift the table without worrying about knock-knees, but they also allow one to operate the table without having to stand up. These tables are especially popular in places where access to electrical outlets is limited or even non-existent because they use an alternative method of power.
Table top units that are vacuum driven and are used with cnc router tables are often called CNC milling machine units. There are a variety of reasons why these routers may need to be vacuumed. The first and most common reason to do this is because the lubricant used in the router has built up enough pressure that it needs to be expelled from the machine. Another reason that these devices can experience pressure buildup is because it is being held down by static electricity. Another reason that the lubricant buildup may occur is if a CNC router arm is disconnected from the computer numerical control system (CNC) computer. Regardless of the cause, these types of operations will typically require a vacuum treatment on a regular and consistent basis.
While the above two reasons may seem somewhat frivolous, they do illustrate how important it is for the operator of a CNC router table to be aware of the potential damage that may occur. In addition to the lubricant buildup mentioned above, wood pieces that are not properly prepped can experience excessive warping. Also, metal pieces can experience extreme changes in temperature during operation. All of these conditions can create a potential problem for the machine aluminum casing surrounding the wood or metal piece. The only way to ensure that these materials do not become affected is to be sure that the tables are thoroughly oiled and that all possible contact is eliminated with an anti-static agent. Another great way to prevent aluminum pieces from becoming impacted is to use small amount wood or metal plated machine aluminum cases.
When operating the CNC routers and the machines around them, it is critical to always pay close attention to all the moving parts, such as the CNC router machine, the CNC table, and the parts of the wood or metal pieces that make up the finished product. By ensuring that all moving parts and components are well lubricated, the wood or metal piece will last longer. These pieces will also be more stable during operation, and the machine will run much more smoothly and will not experience any abnormal lops or jiggling. One of the best ways to prevent the aluminum casing from becoming impacted is to make sure that the tables are well maintained. A regular oiling of the moving parts will help to keep these parts from building up lubricant, which can create a build-up that causes the table to become unstable.
If the above problems occur with the cnc router machine and the operator is not able to solve the problem by manually addressing the issues discussed above, then it may be necessary for the operator to consult one of the many qualified engineers that are licensed and trained in the field of CNC machinery operations. If the engineer is deemed to be competent and skilled, then the operator should be able to have the CNC machinery inspected and serviced by this professional as soon as possible. In some cases, the engineer might even be able to redesign the existing CNC spindle so that it runs more efficiently. If the spindle was designed and built properly, then the operator should not need to make any changes to the hardware within the machine. However, if the spindle has been changed, then it will be necessary to consult the manufacturer and the spindle manufacturer to ensure that the new spindle fits exactly into the machine.
