Generally, the reason for this failure is that the hydraulic oil of the CNC cutting machine is less or particularly dirty, so we must fill the hydraulic oil to the right position in the daily use, and maintain the quality of the oil when in use.　　

The other situation is the filter blockage, sometimes the filter blockage will also lead to the CNC opening machine feed speed is slow, so we try to prevent the above situation in the production and manufacturing.

CNC cutting machine is composed of many parts, among which there are two important parts, consumers must see clearly when buying, that is to play the effect of operation and precision: guide rail and rack.

Guide rail in CNC cutting machine to play a navigation and support effect, the selection of brand guide rail and slider will make the operation of CNC cutting machine more stable, more smooth.

The rack is more important, the rack is connected with the reducer, the rack directly determines the machining accuracy of the CNC cutting machine, the equipment is in operation, the precision of the rack spindle machining precision. And there will be wear and tear of the rack, high-end rack wear is very small, after half a year is very stable, can be used for 5-7 years. Miscellaneous rack wear after half a year is very severe, processing of the plate error will be very big.

So in the purchase of CNC cutting machine, to look at the brand of rack and guide rail, now the best rack from Germany, Taiwan rack and guide rail is very good, must choose well-known brands, bear in mind that can not buy.
