1, Choose Table Size

The users should choose the models and power as per own working demand and capital. Gennerally, Mini SizeCNC router table size is 600*900mm . The basic application of mini table size cnc router is to engrave double-color board. More smaller models prices are similiar with it.

More bigger size models have: 1200*1200mm, 1300*2500mm, 1500*2500mm 2000*3000mm and atc. Now the Acrylic and PVC sheet on offer are 1300*2400mm, so above modelsare available for them.

2, Spindles

Spindles are the important parts of the CNC router, their performances play a key role in overall

machine , the spindles are divided into two kinds. One is precision processing spindles, another one is high power cutting spindles.

1)Features of precision spindles are of lower noise, higher rotation speed, They are applyed for

processing precision workpieces, such as Seal nameplates. Breastplate and etc, the spindles are of higher speed frequency one, power is less than 250w . So They cannot cut off the thick workpieces.

2)High power cutting spindles are mainly for cutting off, deep engraving. The features are of super power, specially for cut out texts and 3D texts , surely they can make the small nameplates and atc.

This kind of spindles contain Brushless higher rotation AC spindles and Brush AC spindles.

The differences between them are :

A . The rotation of brushless spindles are higher , large speed change range, up to 700-60000RPM. But brush one cannot beyond 24000RPM.

B. Brush one rotating precision is higher, less wear, lower noise.

C. Brushless one stall features are better, so short stall cannot burn the spindle motor, but brush one will be burned when stalling and overloading.

D. Speed regulation of Brushless spindles are from Frequency conversion technique, durable and longer life, the supplier also offer 1 year gurantee on quality . And it is also availabel to change bearings inside to prolong usage.

3, Choose machine controller and speed .

A, All operations must be completed by PC, The pc must be under working conditions when machines work, then the PC cannot operate others works .

B. MCU control , this controller can save computer from single work, The PC can make designs when machine works.

C, USB tranfer, after save the data into the DSP panel , the PC can close and make other works, this improve working efficiency of cnc routers.

4, Rails

Big size CNC routers must adopt imported widen square rails , The bearing and precison are 30times than round rails.

5, Precision

The small size routers engrave 1 mm, or big size routers engrave 1.5 mm texts, they must be clear by magnifying glass.

Design software and Control software.

1. Design software

· You could choose any editing software you are familiar with;

· To the 3D relief sculpturing works, professional design software are demanded, such as Artcut

(WenTai), Type3, Artcam, or other types.

· In fact, the principle is the same; software selection is not closely related to machine brands;

that means, the saying: different brand machinery, different design software is NOT reasonable

scientific idea.

· The main difference is different program format demands, usually G code is most popular.

· (with your familiar design software, make out your products, generating G code. )

2. Control software

· Then read G code by CNC router control system (such as Artcam), to finish machining works.

Warm Notice:

· For woodworking furniture industry, Type3, ARTCUM etc. Are advised, and perform very well.

· ARTCUM is most suitable for 3D relief embossment.

· For advertising industry, there is no strict rules, any is ok.

· To the 3D relief sculpturing, most suitable tools are ball nose tools and flat bottom carbide

cutter.

Tips for CNC Router Aluminum Cutting

Don’ t be in a hurry

A CNC Router can cut aluminum. The price you’ ll pay for success is slowing things down. Note that we don’ t mean to literally slow down your feeds and speeds, but your overall Material Removal Rates will be less than what can be achieved with a purpose-built CNC mill. So relax and let the machine do its thing. At the very least, a good sized CNC Router can fit a lot more material on its table than most any CNC mill. Load it up, press the green button, and walk away.

Watch cut depths and slotting– they make it harder to clear chips

The deeper you cut and the closer to a slot the cutter travels in, the harder it is to clear the chips

out of the bottom of the hole. Make more passes to cut down to required depth and to open up the shallower depths for better access.

Lubricate with oil mist.

Assuming you’ re suitably paranoid about those chips, the next issue is providing lubrication to cut down on the tendency for the chips to stick to the cutting edges. You pretty much have to use some kind of lubricant. Since you’ ve presumably already rigged up a compressed air blast, you may as well run coolant mist through the same mechanism. In fact, buy a mister to provide air blast and coolant mist. It’ s easy and inexpensive.

Differences between stone working CNC Router and Advertising CNC Router

1. Stone working CNC Router must choose higher power spindle. At least 3.0kw power . Then the machine can make the efficient carving .

2. Stone working CNC Router must installed with water groove and water spraying system . Cooling bits in case of bits over hot.

It is better that to choose rack and pinion as the transmission on stone working CNC Routers. Firstly , the running speed is fast, secondly , water groove could be larged in rack and pinion CNC Routers , then the cooling water could be slowed out but not on rack and pinion. But for advertising CNC Routers. Cooling water is easily release and less the CNC Router life.

Stepper vs Servo Motors:

The following will attempt to justly compare stepper vs servo motors assuming the following:

-The motors are of equal rated power

-Both motors we are comparing are of same quality

-Servo is equipped with an encoder

-Stepper is not equipped with an encoder

-The driver is assumed to provide the same features excluding feedback options

-The Servo motors are of DC Brushed type

Keep in mind that this is a comparison only and not a determination on which motor is “ better”. Both motors should be viewed as separate technologies, both of which are capable motors given the correct setup and use.
