CNC wood router

CNC wood router
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.


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.

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.

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.
