Seller grinding sanding machine allocation because of man-made board production scale expands unceasingly, most of the sand light choose combination, namely the '2 + 4', '4 + 4' and '2 + 4 + 4', sanding dividends 3, 4, 5. Choose this way of combination of multichannel grinding must be correctly allocated each grinding amount. ___________ in grinding quantity distribution condition correctly, first of all should be concluded that the following conditions: (1) grinding total number (2) the sanding machine sanding traces. (2) the sand with grain size distribution. Especially the last line of the abrasive belt granularity. 2.  The allocation principles (1) make full use of coarse and fine, fine sand with characteristics of right amount distribution grinding amount, generally fine grinding, fine grinding of grinding amount can be concluded that coarse sand depends on the actual situation. (2) the amount of fine sand and fine sand quantity too small, must be able to remove on a sand. (3) on the surface of the best grinding, make the electricity at the same time, abrasive belt cost minimum. 3.  Grinding quantity distribution grinding quantity generally choose hindcasting. Concluded that a final grinding quantity, and then conclude that the final of the second grinding, finally concluded that the first line of grinding. According to the market demands for surface quality, and finally a requirement to choose 150 # abrasive belt, the total amount of grinding to 2. 2 - 2. 8mm。 According to the above conditions, first choose abrasive belt is 40 #, 80 #, 120 #, 150 #, then choose the fifth grinding amount to zero. 15mm（ Double sided) And the fourth grinding amount to zero. 15mm（ Double-sided, combination of sand grinding pad) And the third grinding amount to zero. 4毫米( Double-sided, combination of sand sand roll) And the name of the second grinding amount to zero. 5mm。 1 - the first grinding quantity 1. 6mm。 4. Grinding quantity allocation methods select by allocation methods, first according to the grinding quantity distribution, concluded that each sanding finished thickness size. According to determine the thickness of size, sand the first first, after a few abrasive belt temporarily removed. After the first line of the slab size meet the requirements after sanding, put on the name of the second sand belt grinding, it concluded that the second but thick size, and so on. Until a final size requirements, generally when decided that each size, sand at least two conform to the requirements of the size, we can conclude that the sanding has adjusted correctly. 5 sanding machine grinding caused by improper allocation problems: (1) coarse sand grinding amount is too small, will increase the burden of fine sand and fine sand, make the fine, fine sand belt consumption increase, cannot make full use of the function of coarse sand, fell, feeding speed affect the production efficiency. (2) the way too much grinding, before or after grinding quantity is too little, can cause intensive lateral corrugated ( Is actually from the transverse corrugated unsolved, and at the same time, after two transverse corrugated overlapping) The lower surface roughness. Visible, correct grinding amount allocation, not only can improve the quality of the plate, but also can save the abrasive belt, reducing energy consumption, improve production efficiency. It is worth noting that chooses the way after the adjustment, should according to actual condition in the process of using appropriate trace adjustment, because of the grinding process is a variable, abrasive belt wear, grinding pad wear, density and hardness of the plate in the change. How to fine-tune, need to accumulate experience, through the mechanical properties of each device. According to the above method after the adjustment, after generally don't need to do a big adjustment, even in the transformation of the specifications of the slab also don't need to do big adjustment, because of the eccentric wheel, grinding pad location for record, avoid some wrong operation and needs to be adjusted. Denominated in sanding machine adjustment to achieve sanding machine grinding amount allocation right, it must adjust sanding machine. Sander adjustment under the general selection frame benchmark principle, namely the first adjustment under the frame, then the following frame as a benchmark to adjust on the rack. Harder to adjust the frame must be raised on the rack, the article selects the ruler and the type level fine adjustment, time is longer. After adjusting the next frame, so users should remain under the frame, make the necessary notation, it will greatly save time. Usually the machine before delivery, have finished basic adjustment, debugging personnel on the scene to fine tune. But users are use for a period of time or replace the parts, will be a wide range of adjustment. So maintenance personnel must master the adjustment method.
