how to buy a good cnc wood router?

rd follows 5 of point to you best to choose a good cnc engraver cutting machine

1, working size selection
Customers should be based on business needs and financial situation , to choose their own engraving machine the size of the model and its power . eral small-format engraving machine has 600mm × 600mm and 600mm × 900mm, the feed width is 700mm. Engraved color plates is small format engraver most basic appliion , acceptance is very good. And then a little engraving machine and its almost the same price , but when carving color plates to the Conference Board , more cumbersome and unnecessary waste . Large format engraving machine has 1200mm × 1200mm, 1200mm × 1500mm, 1300mm × 1800mm, 1200mm × 2400mm, 1300mm × 2500mm, 1500mm × 3000mm, width over the engraving machine models into families of more than 1350mm, plexiglass and now available PVC plate dimensions are 1300mm × 2400mm, so that several models of customer needs large format engraving machine is more suitable.

2, Spindle motor
Spindle motor is an integral part cnc engraver cutting machine , its performance on cnc engraver cutting machine machine performance has a critical influence . Processing Spindle usually divided into two egories: high- precision machining spindle and cutting Spindle.
( 1 ) , fine processing Spindle is characterized by low noise, high speed, altitude, especially suitable for processing fine artifacts, such as sls , nameplates , badges and other gifts. Such motors are usually high-speed variable frequency motor , less power , like the 250W or less. The disadvantage is the poor ability to cut thicker materials , are not cut thicker materials .
( 2 ) , power cut Spindle, mainly used for cutting , high-power engraving, is characterized by power, cutting ability, especially for cutting -yu , three -dimensional characters, of course, can produce badges , nameplates , sls and so on. According to the characteristics of such power Spindle motor frequency can be divided into high-speed brushless AC motor and AC motor brush .

3 . Control mode and speed selection: control now can be divided into three types:
A, all the work is computer-controlled operation is completed , cnc engraver cutting machine at work, the computer is in working condition, can not be other typesetting , this may result in solid waste computer misuse .
B, using SCM control , this controller can be typeset in cnc engraver cutting machine work, but you can not turn off the computer , which is actually equivalent to savings of 7 a computer, computer misuse and reduce waste caused .
C, using USB port to transfer data , the system has more than 32M of memory . Just save the file, you can right away completely from the computer , turn off the computer or other typesetting . This approach grtly improves the efficiency of cnc engraver cutting machine .

4 , rail
Large format cnc engraver cutting machine must be widened using imported square rails , load capacity and accuracy to maintain its ability to round rail is more than 30 times , to ensure the high quality cnc engraver cutting machine speed .

5 , precision
Small-format machine carving 1mm characters, or large format cnc engraver cutting machine engraved 1.5mm small print , under a magnifying glass to be seen very clrly.
CNC engraving equipment is a new industry , its products are widely used in doors and , crafts , advertising , stone carving and other industries , with carved high precision, high efficiency quickly carved open trade markets. After several yrs of development cnc engraver cutting machine technology has matured, while attracting a large of investors to enter the industry , resulting in uneven levels of industry manufacturers , following on how to choose cnc engraver cutting machine to do the following description:
( 1 ) , the purchase of CNC engraving equipment types , we must first determine the technical requirements and business process specifiions required for processed products , determine the type of cnc engraver cutting machine according to the needs of process and production line bt , cnc engraver cutting machine types are are many, only selected the correct type and size to achieve the best effect, to achieve the best cost performance.
( 2 ) , buy cnc engraver cutting machine manufacturer , is directly related to the level of production enterprises scale, size and technical strength to cnc engraver cutting machine performance. Select the device there are many manufacturers make irrational and unrsonable place of birth defects in the device manual and see if the appliance can not understand the sample , promoters and manufacturers always choose to introduce all the advantages of the equipment to the customer . The is to pay attention to an issue , and some domestic enterprises to establish quickly, while the closure is also fast, sometimes there will still factories have closed down equipment salesman selling phenomenon. If you pay attention to these issues, it will appr in the cross machine when the machine acceptance and warranty. Manufacturer closed down, the device working properly, failure can not be repaired , the manufacturer could not fulfill the requirement of one yr warranty . At the same time , such plants must be the original data and maintenance of equipment incomplete information , the user will be difficult to repair . So choose the company as a high -profile manufacturers choose .
( 3 ) , choose well-known brands and have a certain reputation brand equipment, many domestic manufacturers of CNC engraving equipment , many have a certain strength of CNC engraving famous manufacturer has its own products and brands .
( 4 ) , select System CNC engraving equipment used , the so-called selection system , erally choose more famous brands of systems , but this is not the , the lies in the choice of system development and the ability to use their own production of CNC engraving . Because many systems are quite perfect function , the manufacturer of various functions of the system ( except the commonly used functions ) has a certain fixed price , which is business- spk procurement system functions understanding insufficiency, when not in the procurement of equipment proposed for various functional requirements of the system , then the plant provides eral common ftures only found the missing functionality to the manufacturer requested production plant will be in the grounds of lectual property rights , they should also pay for when you pay machines, as well as the plant itself would not call this function developed, he refused to provide the contract shall prevail fture , which will give full play to the superiority and efficiency of users of CNC engraving equipment erates considerable limitations , where the selection system when must consider the production of CNC engraving equipment business use and functionality of the system development capabilities . Users in the negotiations , the full functional requirements of the system proposed , so that the device can fully play its role , but also can be versatile CNC engraving equipment spending a penny on the basis of little , if companies have alrdy purchased domestic CNC engraving the device will add a touch function will incrse the price and in the negotiations to the last Mini -friendly ftures to show something , but do not forget this fture originally CNC engraving equipment we buy should have.
( 5 ) , a variety of raw materials and essential equipment maintenance information . Before a final agreement is not rched , we must all kinds of raw data and maintenance information to be provided by the supplier of CNC engraving equipment , through the study and understanding of these materials , to the production of plant capacity and design capabilities have a certain understanding , if this neglice work , it will make the device into production after erating a lot of unnecessary trouble. Because the domestic manufacturers of CNC engraving equipment subject to random data the ability to influence the production of plant design , erally not very perfect. Some companies are more perfect , but they will not provide more complete information on equipment procurement and maintenance information to the mainland enterprises .

So, before we buy equipment , all data must have a clr understanding of the equipment , including CNC engraving eral information : (1 ) Operating Instructions Manual ; ( 2 ) Programming manual ; ( 3 ) an exploded view of the mechanical structure ; and detailed distribution ( 7 ) cooling system diagram ; ( 5 ) wk structure diagram , a detailed joint arrangement diagram ; ; ( 6 ) hydraulic and hydraulic schematics detailed maps ( 4 ) strong electrical schematic diagram and detailed arrangement connection diagrams ; ( 8 ) lubriion system schematic and detailed distribution arrangement diagram ; (9) Spindle cooling system schematic diagram and detailed connection arrangement ; ( 10 ) equipment PC chart ; ( 11 ) equipment system operation manuals and maintenance manuals ; ( 12 ) method for setting various parameters and Spindle parameter setting methods, uses parameters ; ( 13 ) equipment testing method ( including mechanical and electrical ) ; ( 14 ) various sensors layout, electrical parts list , and a variety of sy list of consumables ; ( 15 ) common troubleshooting methods ; detailed information sheet ( 16 ) of various purchased parts , manuals , and electrical machinery
