How to make right choice in buying Nc Cut Off?
First,The brand of the cutter must not be too obscure, that is, you can't find a brand that is not well-known. Because there is no guarantee of quality for unrecognized brands, there are not too many samples and drawings of the cutter. Therefore, you need to find a trusted big brand for custom cutters.
Then,It is necessary to know whether the brand custom knife technology is based on consumer needs. From the selection of custom knife to the closing, it is completely customized according to consumer needs and requirements, and at the beginning of the design, consumers are allowed to interact and participate in the blade design. In this way, the final cutter is integrated with the mechanical equipment to ensure the operation of the production.
Finally, it is necessary to determine the quality assurance of the knife manufacturer and provide after-sales service
The cut-off has two ways of cutting paper, straight knife Cut Off Machine crosscutting and spiral knife crosscutting .Straight knife cut-off relies on the depth of the groove, the width of the crosscutting knife to achieve the rotary cutting board, by the groove depth, the width of the crosscutting knife restrictions.The shearing angle of the straight knife cut-off is relatively all, and the strength is not good when shearing, suitable for medium and low speed production line.The cut-off of spiral cutter opens a spiral cutter groove on the cutter shaft, and the cut-off is installed on the cutter shaft to form a spiral cutter with large shear angle, ooth paper cutting and labor-saving. It is suitable for cutting high-strength triple wall corrugated board on the medium-high speed production line.
The computer control type straight knife cut-off use and the Cut off Blade maintenance cost is low, the straight knife thickness is big, the service life is long, and the price is lower. Computer controlled spiral cutter cut-off is a relatively new technology at present, its design adopts low moment of inertia cutter shaft, cutter shaft is all, relatively easy to control, less power, can achieve high-speed production requirements.
For example, the speed of 300 meters/min of the new all inertia Nc Cut Off , each motor power is 22KW, two motors power is 44KW.A speed of 300 meters/min of the traditional cut-off, motor power is 75KW.
According to the calculation of the daily operation of the cut-off for 16 hours, Cut off Knife can save :(75-44) KW * 16 hours =496 KWH of electricity, and the annual cost can be saved about $21,000.The comparison of advantages and disadvantages of spiral low-inertia cutter and spiral ordinary cutter are as follows:
