 1 selection of the working size

The customer should be based on business needs and financial situation, to choose their own engraving machine , the size of the model and its power. Generally a small size engraving machine with 600mm × 600mm and 600mm × 900mm, the table width is 700mm. The most basic application for a small working size engraving machine is color board engraving. A smaller engraving machine is almost  the same price, but when carving a color board it needs cutting, it is more cumbersome and unnecessary waste. Large working size engraving machine with 1200mm × 1200mm, 2000mm × 1500mm, 1500mm × 2400mm, 2400mm × 3000mm, these models with the table width more than 1350mm, and normally the plexiglass and PVC board size are 1300mm × 2400mm, so these several models are more suitable for the customers who need for the .large working sizes machines.

2 The spindle motor

The spindle motor is an important part of a cnc router , the performance has a critical influence for a cnc  engraving machine. The spindle is usually divided into two kinds: precision machining spindles and large power for cutting 1precision machining spindle is characterized by low noise, high speed, especially suit for fine machining of the workpiece, such as seals, nameplates, badges and gifts. Such motors are usually it is high-speed variable frequency motor, less power, 250W or less. The disadvantage is not suitable for thick materials.

2, large power spindle, is mainly used for cutting, characterized by high cutting ability, especially for cutting premises, three-dimensional character, of course, you can create badges, nameplates, chapters and so on. Such high-power spindle motor according to the characteristics of the frequency can be divided into high-speed AC brushless motors and brush AC motor, the main difference is: A, high-speed brushless frequency conversion motor, variable speed range from 70.06 million r / min, while generally AC brush motor maximum speed not exceeding 24 000 r / min: B, brushless motor with high precision, small wear, low noise, C, brushless frequency conversion motor stall characteristics, and because inverter current limit on the special circuit, short-burn motor will not stall, while the exchange machine overload the brush or stall smoke will burn quickly, and not repairable; D, brushless frequency conversion motor using variable frequency speed control technology, is a professional grade products, long life, the manufacturers provide 1 year free replacement, after replacement of high-speed bearings can also perform maintenance on the motor, while the use of electric AC motor brush life Sapporo approximately 300 hours have to replace the motor or brushless motor, brushless AC motors are usually one day so no warranty.

3. Control mode and speed selection: control can now be divided into three types: A, all computing tasks are complete computer control, computer engraving machine at work is in working condition, can not be other layout work, this error may be fixed computer operation resulting in waste. B, single-chip computer control, this controller can work in parallel engraving machine layout, but can not turn off the computer, which in fact is equivalent to savings 7 a computer, computer misuse and reduce the resulting waste. C, using USB port to transfer data, the system has more than 32M of memory. Save the file as long as the end, you can immediately completely out of the computer, turn off the computer or other layout. This approach greatly improves the efficiency of engraving machine.

 4 the rail large format cnc router must use the square rail wider import, load capacity and accuracy of its ability to keep track of more than 30 times round, to ensure high-quality high-speed engraving machine.

5 cnc router carving 1mm precision small-format character, or large format engraving machine engraved 1.5mm small print, under a magnifying glass to be seen very clearly.
