5 Criteria to Guide Your CNC Choice

The purchase of a CNC machine is no small investment, and the variety of available options can befuddle just about anyone who's not an expert. To help you narrow your options and hone in on the right CNC machine for your shop, we've identified five variables you should consider:

1. Duty cycle: Do you plan to use the machine for occasional hobby projects or for more sustained production purposes?

2. Capacity: How big do you anticipate these projects will be? For example, do you expect to make large outdoor signs or small wall plaques? While software allows smaller machines to work on larger projects in "tiles," a machine with a larger "working envelope" might be worth it because of the setup time and effort it will save you.

3. Durability: Is the machine robust enough to maintain its accuracy over time? For how long? Lighter-duty machines often do not hold their tolerances as well as more rigidly built machines.

4. Power: What type of motor or spindle will the machine have (or require), and what's the horsepower capability? Power determines speed and quality of the cut. Some CNC machines are designed to fit a compact router motor; some can accommodate larger router motors; some come with water-cooled spindles; and some have spindles that use other liquid coolants. In general, spindles make less noise and are built specifically to run for extended periods of time. So a more serious user probably will want a liquid-cooled spindle, while a casual user might be happy with a router motor or water-cooled spindle.

5. Value: Are all of the important components included in the price, or are they considered add-ons that must be purchased in addition to the machine? Some machines include such items as design software and a touch plate or puck for easy setup, while others sell every item as an accessory. Additionally, some require the user to have a computer attached to the CNC machine at all times, while others have a handheld controller onto which files can be loaded via a USB port.

5-Axis CNC Routers

multi-axis capability is affordable.

The Roc-tech 5-Axis CNC Router is ready for production cutting, drilling, trimming, as well as prototype-and fixture-machining in a large work envelope, accessible from all angles.

5-Axis CNC Router is built on rigid modules with extended height that allows good 5-axis reach. The X axis is a moving table based on the innovative system. The Y axis makes use of the precision extruded beam.

The tool is perfect for 5-axis machining of soft materials such as urethane foams, as well as trimming, drilling, and slotting operations in a variety of materials such as vacuum formed ABS. It is capable of light machining in soft woods, but does not have sufficient rigidity for machining of hard-wood or aluminum.All 5 axes are powered by advanced technology,closed-loop, alpha Step motors providing production speed and precision. The tool includes a 2.2hp HSD spindle fit to the 5-axis head. The 5-axis head, or wrist, utilizes 2 motors. These are “hollow rotary actuators” providing a wide rigid base and stable motion for the two additional axes of rotation.

CNC wood router

A CNC wood router uses CNC (computer numerical control) and is similar to a metal CNC mill with the following differences:

• The wood router typically spins faster — with a range of 13,000 to 24,000 RPM
• Professional quality machines frequently use surface facing tools up to 3" in diameter or more, and spindle power from 5 to 15 horsepower. Machines capable of routing heavy material at over a thousand inches per minute are common.
• Some machines use smaller toolholders MK2 (Morse taper #2 - on older machines), ISO-30, HSK-63 or the tools just get held in a collet tool holder affixed directly to the spindle nose. ISO-30 and HSK-63 are rapid-change toolholding systems. HSK-63 has begun to supplant the ISO-30 as the rapid change standard in recent years.

A wood router is controlled in the same way as a metal mill, but there are CAM and CAD applications such as Artcam, Mastercam, Bobcad, and AlphaCam, which are specifically designed for use with wood routers.

Wood routers are frequently used to machine other soft materials such as plastics.

Typical three-axis CNC wood routers are generally much bigger than their metal shop counterparts. 5' x 5', 4' x 8', and 5' x 10' are typical bed sizes for wood routers. They can be built to accommodate very large sizes up to, but not limited to 12' x 100'. The table can move, allowing for true three axis (xyz) motion, or the gantry can move, which requires the third axis to be controlled by two slaved servo motors.

Types of CNC Routers

Types of CNC Routers

Wood

A CNC wood router is a CNC Router tool that creates objects from wood. CNC stands for computer numerical control. The CNC works on the Cartesian coordinate system (X, Y, Z) for 3D motion control. Parts of a project can be designed in the computer with a CAD/CAM program, and then cut automatically using a router or other cutters to produce a finished part.The CNC Router is ideal for hobbies, engineering prototyping, product development, art, and production work.

Metal

Milling is the machining process of using rotary cutters to remove material from a workpiece advancing in a direction at an angle with the axis of the tool. It covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes in industry and machine shops today for machining parts to precise sizes and shapes.

Stone

A stone CNC router is a type of CNC router machine for marble, granite, artificial stone, tombstone, ceramic tiles, glass carving&engraving&cutting&polishing as arts and crafts, pictures, etc.

Is this the standard name for our product, CNC Router Machine?

Ah, we use this name we deem as standard to set up a website to include what we think is related to CNC technology.

As other industries do, CNC Router industry also needs the establishment of a world-wide platform for people with interests to share with their thoughts, for suppliers to post their product information and for buyers to put up their demands so that the information can be exchanged beyond the physical limitations.

And the setup of an international organization for this industry is also necessary.

Are you cost-sensitive for the projects to take? Does your project not require that sophisticate and numerous functions to be processed in the same time? Maybe we can consider such 3-axis CNC Router machines.

For most of the actual projects and applications requiring CNC Routers, we do not need that fast speed and we do not need that delicate operations. And we can tolerate some deviations from accuracy. Of course, we also need to consider the ratio between performance and cost. So, we will sometimes just need a simple 3-axis CNC Router. Because the application is not that complicated, so when you use a 3-axis CNC Router to do with it, you will find, wow, the speed is enough for me.

And, it is cheap!

Do you think such 5-axis CNC Routers advanced enough? Or do you think such 5-axis CNC Routers expensive enough? Maybe we can consider such relatively costly products for our complicate applications.

In actual scenes, there do exist some complicated applications which require much delicate operations, high processing speed and absolute accuracy. For such applications, low-cost 3-axis and 4-axis CNC Routers will be unable to deal with. Here we need the 5-axis CNC Router to accomplish what we need.

4-axis CNC Routers are rather suitable for most of the application requirements, either multi-functional or cost-sensitive. We choose such 4-axis CNC Routers for most of our DIY practices.

Some people think that 3-axis CNC Router is too low for their needs， which cannot accept the high cost of 5-axis CNC Routers. Thus the 4-axis CNC Router will be a better choice for both performance, speed and cost considerations. It can meet the requirements of most demands in actual life. And it is also rather convenient.
