How to achieve the best performance multi-chip saw blade alloy

In order to play a round alloy saw its best performance , must strictly observe the following points: ( 1 ) wire tapping machine should have a good performance, no vibration. ( 2 ) the size of France blue plate diameter should be consistent about French blue plate surface in contact with the saw blade saw blade diameter of 1/ 3 ( 3 ) should be perpendicular to diamond bandsaw blades  the centerline of the hole . ( 4 ) at both ends of the gasket surface should be parallel and perpendicular to the centerline of the hole .
( 5 ) Saw spindle runout straightness and definitely not super bad, spindle diameter does not exceed the tolerance H7 (6) multi-chip saw blade clean before installing the first , if the blade body sticky with resin , thinner wiping required go, and saw the body is coated with a protective layer , it can be wiped off with hot water , avoid using corrosive solvents. ( 7 ) If the blade has insensitive , should immediately grinding , taking care to keep the original serrated cutting angle . ( 8 ) when grinding not only to choose a suitable diamond grinding wheel, but also the use of coolant. ( 9 ) blade reamer recommends no more than 20 mm of the original hole , otherwise it will lead to loss of photos , then the effect will be affected by the cutting blade . ( 10 ) Each installation must ensure law and blue plate washer clean and smooth. ( 11 ) when the repair after grinding angle and saw the body must be careful not to manual operation, will result in jagged fragments and saw the body imbalances. ( 12 ) Gangsaw installation, careful iron rack and need feeding chamber was the same level. ( 13 ) before cutting blade to check whether the tightening has been installed , to prevent slipping on the  masonry drill bits shaft displacement and the blade . 1 blade If not used immediately , it should be flat or use the hole to hang it up, can not be stacked on other items or foot flat blade cutter , and pay attention to moisture, anti- corrosion. (2) When the blade is no longer sharp cutting surface roughness , it must promptly re- grinding. Grinding can not change the original angle , and destruction balancing . 3 inner diameter of the blade correction , the positioning hole machining , etc., must be performed by the manufacturer . If the process is bad, will affect the product effect, and potentially dangerous , reaming should not be over the original aperture 20mm, so as not to affect the stress balance. Choose alloy wheels 4 .
1 ) resin bonded diamond grinding wheel bond strength is weak, and therefore capable of self-sharpening grinding is good, clogging, high grinding efficiency, low grinding force , grinding temperature is low , the disadvantage is poor wear resistance, abrasive wear and tear , it is not suitable for heavy duty grinding.
2 ) vitrified diamond grinding wheel wear resistance and superior binding capacity of the resin binder, cutting sharp, high-alloy blade grinding efficiency , easy fever and congestion, less thermal expansion , easy to control the accuracy and disadvantages coarse grinding surface , higher cost .
3 ) high metal -bonded diamond grinding wheel bond strength , wear resistance, low wear, long life, low grinding costs , can withstand a greater load, but sharp poor, easy to plug .
4 ) There grit size wheel jam circular blades  and cutting the amount of a certain influence , coarse sand and fine sand compared , large depth of cut increases abrasive wear of the cutting edge , and vice versa wheel easy to plug .
5 ) Wheel hardness greater impact on clogging , high hardness, high thermal conductivity wheel is not conducive to the surface of the heat , but help to improve the machining accuracy and durability.
6 ) Wheel concentration choice is an important feature, its grinding efficiency and processing costs have a significant impact , affecting the efficiency of the concentration is too low , whereas abrasive easy to fall off , but the best combination of agent concentration range
