In this post, we are going to share four tips guide concerning buy cnc router, hope it is helpful for you.
First, should be powerful. The main factor that affects this is spindle motor power. The spindle motor can be divided into air-cooled and water-cooled according to the different cooling ways. The power of water cooling is generally 1.5 / 2.2 / 3.2 / 5.5 KW, EagleTec 4x8 cnc router is normally equipped with 3.2kw water-cooled spindle, which is absolutely enough for woodworking and sign making jobs. Air - cooled spindle power is 3.5 / 4.5 / 6.0 / 7.0KW. Water cooling spindle can hold 12.7mm router bits maximum; while air cooling can hold 20mm maximum. Spindle size should be selected according to material and job features. From all the above, the spindle should be selected carefully when buy cnc router.

Second, should be fast. Speed and efficiency are important in modern industry. Make it as fast as possible under the condition that spindle power is enough, also need take router cutter capacity and machine service life in to consideration. Quality cnc router should be equipped with big torque motor or servo motor, large driver (example: YAKO YKA2811). The driving system will not burn and will not over-load after long and fast machining process.
Third, should be good accuracy. Precision is the most important parameter of cnc router machine. It is not easy for cnc router to have high speed machining and high accuracy meantime, but it is the feature that a high quality cnc router machine must have. This also tests the production level of cnc router machine manufacturers, criterion is that long hours of good work regardless of carving and cutting, smooth and straight.
Forth, rigidity should be sufficient. Machine construction should be designed reasonable and make it firm.
