What should we pay attention to when choosing woodworking engraving machines?

What should we pay attention to when choosing woodworking engraving machines?

Woodworking engraving machine is mainly used for woodworking processing, make it more beautiful. Woodworking engraving machine types currently on the market price of the product variety, quality is uneven, so we need to select the choice to buy carefully, JINAN Xiao Jia CNC machinery Equipment Company will introduce five points for helpping you buy suitable wood engraving machine.

First,
Working size of engraving machine

Customers should select the type of engraving machine and the size of its power according to the needs of the business and the funds. Generally small format engraving machines have 300mm * 300mm and 600mm * 900mm. The engraving of double swatches is the basic application of small engraving machines, and the reception is very good. A little smaller engraving machine and its price is not much difference, but the engraving of the double color palette to cut the plate, more troublesome, and unnecessary waste. Large format engraving machine with 1200mm * 1200mm, 1200mm * 2400mm, 1300mm * 2500mm, 2000mm * 3000mm, into the Department of engraving machine models more than the width of more than 1350mm, now organic glass and PVC board on the market size is 1300mm * 2500mm, so that several models of surface engraving machine customer demand suitable.

Second, we should pay attention to engraving machine spindle motor

Spindle motor is an important component of cnc engraving machine, and its performance has a crucial impact on the performance of computer engraving machine. Machining spindles are usually divided into two types: precision machined spindles and high power cut spindles.
1, fine machining spindle is characterized by low noise, high speed, height, suitable for processing particularly delicate workpieces, such as seals, nameplates, chest cards, gifts and so on. This type of motor is usually a high speed variable frequency motor with less power and less than 250W. The disadvantage is that the ability to cut thick materials is poor and does not cut off thicker material.
2, high power cutting spindle, mainly used for cutting, high-power engraving, characterized by large power, cutting ability, especially for cutting Yu, three three-dimensional characters, of course, you can also make chest cards, nameplates, seals and so on. Such a large power spindle according to the characteristics of the motor can be divided into brushless frequency high speed AC motor and brushless AC motor, the main difference is: A, brushless frequency motor for high speed, speed range of 700-60000 rpm, and generally have a brushless AC motor maximum speed does not exceed 24000 RPM: B, no the rotating precision brush motor, small abrasion, low noise, noise is much lower than for brushless AC motor; C, brushless frequency motor stalling characteristics, the frequency converter with current limiting circuit, a short block not burning motor, and brush AC machine overload or stall will soon smoke burning, and can not be repaired; D, adopts frequency conversion speed control technology of brush motor, is a professional grade products, long service life, the manufacturers to provide 1 years free replacement, later also can be replaced by high speed bearing of motor Line maintenance, and brush AC motor, due to the use of electrical life of about 300 hours, you have to replace the motor or motor carbon brush, so carbon brush AC motor usually has no warranty.

Third, engraving machine control mode and speed

Control modes can be divided into three kinds now:

A, all of the operation has computer control, engraving machine at work, the computer is in the working state, can not carry out other typesetting work, this may fix the computer misoperation and cause waste.

B, the use of single-chip control, the controller can work in typesetting engraving machine at the same time, but does not turn off the computer, this is actually equivalent to savings of 7 of a computer, and reduce the misoperation caused by the waste computer.

C, using USB port to transmit data, the system has more than 32M of memory capacity. As long as you save the file, you can leave the computer immediately, turn off the computer, or do some other typing. This method greatly improves the efficiency of the engraving machine.

Forth, that is, the accuracy of engraving machine

Small plane engraving 1mm Chinese characters, or large format engraving machine, carved 1.5mm letter, under the magnifying glass to see very clearly.

Fifth, pay attention to the guide rail

Large format engraving machine must adopt wide imported square guide rail, its load capacity and precision retention ability is more than 30 times that of circular guide rail, which guarantees the high quality and high speed of engraving machine.

Common failures and Solutions of CNC Router

Common failures and Solutions of CNC Router

Any machine can not be preserved intact for a long time,so we should learn to  

judge the common faults and know how to solve them.Here we share some common failures and solutions of cnc router, and we mainly have the following 15:

Ⅰ, the spindle automatically turn or can not stop

1, control card failure;

2, inverter fault

II, when opening the software, the computer prompts "open the card failed,

please check the card" prompt

1, check the driver card is not installed, or to change a PCI card slot;

2, the two data connection line to re install, check there is no phenomenon of 

broken needles;

3, the board has a problem, replace the board.

Ⅲ,Open the software when prompted: three axis alarm, initialization error four

1, check the computer and the machine two data lines have not received;

2, check the control box of the switch board of the fuse is burned, for the 

fuse;

3, check the 85V power supply is normal

Ⅳ,CNC Router appear dislocation or wrong size

1, check the path of the software is correct or not;

2, check the gap size of the screw rod and the rod of the fastening screws are 

not loose;

3, check the software parameter settings correct or not.

Ⅴ,When X axis working,the Z axis can not lift,give it the command go up,but it 

go down.

1, check whether the Z axis motor run well,also check it's power and the drive 

current.

2, check whether the Z axis motor line has bad contact or middle of the case.

Ⅵ,the spindle motor does not turn or reverse

1, check the setting parameters of the inverter;

2, the frequency of the signal line is connected to the inverter.

Ⅶ,Smashing knife phenomenon

1, Z axis motor power is not enough, the coupling loose;

2, Z axis drive current is too small, or signal line is wrong.

Ⅷ,When the software is turned on, the shaft is closed.

1, the problem of the driver or the computer output signal line contact is bad;

2, the motor line contact is bad.

Ⅸ,In the process of engraving, there is a limit phenomenon.

1, check the engraving path is beyond the scope of sculpture;

2, the soft limit of the parameters in the software settings.

Ⅹ,When turn on the machine, it doesn't work.

1, check the start button line is connected and the button is burnt out;

2, check whether the AC contactor short-circuit or burn out.

Ⅺ,Axis running only to one direction

1, check whether the normal work and the coupling line contact line is good;

2, check the motor line for a weld.

Ⅻ,Files cannot be opened normally, and the carved objects appear to be 

deformed.

1, re install the new system and software;

2, check the X, Y axis screw 

XIII,CNC Router's spindle motor suddenly stop or slow down in the process of 

work

1, the operating voltage is not stable or super load, plus a voltage regulator 

can be;

2, check the middle line is connected, whether there is a connecting thread.and screw is loose;

3, carving tools have problems.

XIV,When setting the origin of the engraving machine, sometimes forward, the 

right offset distance

1, limit switch failure, the system back to the system in the process of the 

origin of the limit switch has been closed and open. Change limit switch;

2, drive line loose. Try to fix it.

XV,CNC Router start reset, X axis, Y axis, Z axis position is uncertain

1, limit switch is bad (the limit switch is always closed), can change;

2, the drive line is bad (X axis 14 pin and 15 pin short circuit, Y axis 13 pin 

and 15 pin short circuit, Z axis 31 pin and 15 pin short circuit), change the 

drive line or short circuit can open;

3, the driver board is bad, change the drive board can.
