From the view point of machinery, CNC engraving machine, CNC engraving and milling machine, high speed engraving and milling machine for distinction and selection

Machine tool machine is divided into two parts, moving parts and no moving parts: workbench, skateboard, cross flower-stand for moving parts, such as bed, column, etc. For the moving parts. 1, effective control and milling machining center, the moving parts rigidity requirements very well moving parts rigidity requirements very well. Advantages: heavy cutting can; Disadvantages: due to the mobile part of the same large, at the expense of his machine flexibility, for small part and fast feed could do nothing. 2, CNC engraving and milling machine. Moving part of the rigid requirements good moving parts than a rigid to flexible journey, as less as possible, while maintaining a certain rigidity. Are compared advantages: small machining, precision is high. For soft metal for high speed machining; Disadvantages: due to the poor rigidity so impossible for heavy cutting 3, high-speed cutting machine tools. The moving parts rigidity demands very good mobile section rigidity is better, and as light as possible. Advantages: can in a small amount of cutting ( Pour 1 o flat knife, in general for 45 # steel ( 300). Deep depth to o. 75 is good) ; Disadvantages: can play under the correct use of high efficiency, low cost, make the grinding quantity is very few. Incorrect use, can make the tool scrap pile up soon. How to achieve the above from machinery and light, good rigidity and conflicting demands, the key lies in the mechanical structure of kung fu. 1, the bed body USES the high and low reinforced with mesh architecture, some directly connected with honeycomb hex mesh structure. 2, super wide column and beam, as we all know the gantry structure due to its excellent symmetry and excellent rigidity is high speed cutting equipment manufacturer has been as a preferred structure. 3, for moving parts and the effect of milling significantly difference is widened a lot of the distance between the guide and guide, to overcome the problem of bad moment. 4, tell from the materials commonly used m han that cast iron is cast iron, when pouring molten iron to join a percentage of silicon ( Si) Which changed the internal structure of iron, and make it more resistant to stamping, rigid has improved significantly. 5, machine tool rigidity is mainly used to overcome the moving parts in high speed mobile when strong impact of the moving parts. So guide rail, screw some rough requirements, and strengthen the rigid connection parts.
