How to select CNC router?
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 theAcrylic and PVC sheet on offer are 1300*2400mm, so above modelsare
available for them.
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 ishigh power cutting spindles.
1)Features of precision spindles are of lower noise, higher
rotation speed, They are applyed for
processing precision workpieces, such as Sealnameplates. Breastplate and etc, the spindles are of higher speed
frequency one, power is less than250w . So They cannot cut off the thick workpieces.
2)High power cutting spindles are mainly for cutting off, deep
engraving. The features are of superpower, 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. butbrush 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 onewill be burned when stalling and overloading.
D.Speed regulation of Brushless spindles are from Frequency
conversion technique, durable and longerlife, the supplier also offer 1 year gurantee on quality . and it
is also availabel to change bearingsinside 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 whenmachine works.
C,USB tranfer, after save the data into the DSP panel , the PC can
close and make other works, thisimprove working efficiency of cnc routers.
Big size CNC routers must adopt imported widen square rails , The
bearing and precison are 30timesthan round rails.
The small size routers engrave 1 mm, or big size routers engrave
1.5 mm texts, they must be clear bymagnifying 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
· 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.
· 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

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 wedon’t mean to literally slow down your feeds and speeds, but your
overall Material Removal Rates willbe less than what can be achieved with a purpose-built CNC mill. So
relax and let the machine do itsthing. At the very least, a good sized CNC Router can fit a lot
more material on its table than mostany 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 theshallower depths for better access.
Lubricate with oil mist.
Assuming you’re suitably paranoid about those chips, the next issue
is providing lubrication to cutdown on the tendency for the chips to stick to the cutting edges.
You pretty much have to use somekind of lubricant. Since you’ve presumably already rigged up a
compressed air blast, you may as wellrun coolant mist through the same mechanism. In fact, buy a mister
to provide air blast and coolantmist. It’s easy and inexpensive.
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
-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.
