Diamond thin circular saw blades in the disk saw stone production has played a big role, already saved costs and improve work efficiency. Now is how to use diamond thin circular saw blades, talk about some Suggestions.
A, why should use diamond thin circular saw blades
In the disk saw stone production, how to reduce the production cost, improve the production efficiency and, of course, is the first consideration of waste materials, especially for the material rate the expensive imported especially waste material stone. Choose to use diamond thin circular saw blades, can make the waste materials stone improve the rate of 5% above the material and reduce the cost of waste materials. Also, because of circular saw granite, thinning metallutgy also thinning of the blade is saved, and save the electricity cost, water. Therefore use diamond thin circular saw blades greatly reduces the production cost, every square metre can reduce 10 ~ 40 yuan. So the circular saw blades for the diamond stone production manufacturer needs of light-weight disk saw more and more urgent.
Second, the diamond is the first key to blade sharpness
Because the thickness of the light-weight sawblade from mechanics, thinning perspective, it also weakens the rigid. In order to make have originally the standard thickness of cutting performance, except sawblade rigidity, hardness, end jump etc to reach a certain standards outside, combined the sharpness is the first diamond key. Improve the diamond by following the sharpness coping.keeping five factors decided:
1, improve the diamond, diamond choice generally the intensity of than standard with diamond head high strength 1 ~ 2kg;
2, improve the diamond coarse mesh, namely the proportion of 40/50 # ratio increased to more than 60%;
3 and reduce diamond concentration, be in commonly 25% below;
4, reasonable choice tire body formula, namely Slate easy edged sand-out low-temperature not metal binder formula;
5, shorten the length of blade, make the standard for 21mm metallutgy 24mm shorter length.
Three, reduce the input power
Because the thinning of matrix, its rigid weakens, saw blades have endurance (anti-roll) corresponding decreased; Because the width of blade thinning, length decreases, and cutting resistance reduced; Due to strengthen the sharpness, cutting blade, cutting force improve resistance. So, the original most main electromotor adopt 30kW, can change 22kW, current control in 35A or so, yield can reach the original standards.
Four, prevent thermal stress influence
Thin circular saw blades in welding metallutgy process, should try to low-temperature type silver soldering when piece, welding time hearting (silver soldering pieces so far), prevent melt appear larger heat affected zone; Welding, had better use intervals every 6, general welding gear ~ 8, a week after ordinal take welding welding.
Five, operation methods
1, first slow, quick. First cutting knife, walk slowly, drop knife depth to shallow, let it saw a straight road after 30mm depth about sawing, add go down knife knife speed depth.
2, after the first small. Such as production 600mm wide plate can be directly used to 1600mm circular saw blades one-time cut, such as production 800mm (or 900mm) wide plate, generally USES 1600mm circular saw blades, first cutting 600mm deep, after the replacement 2000mm (or 2200mm) circular saw blades, 200mm (or cutting deepen 300mm). Special attention is, now should be generally replacement blades during cutting, deepen the circle in top alignment cutting blades seam, perform the deepen after cutting, such often appear sawblade edge grinding, make a circular saw fever scrapped. Best method is to alignment cutting, sewing and then dropped to 600mm deep, will cut already cutting blades into inside, then again seam evenly, make both sides clearance adjustment, be carried out only deepen cutting.
3, according to stone hardness, reasonable use cutting depth and take knife speed. General stone high hardness, the knife knife, go to shallow depth is faster, defend the knife too deep, India red generally lower knives, walk around 8mm depth of sword speed of about 2.6 m/s.
4, fixed steering cutting. Without a fixed currently manufacturer in circular saw blades to cut, not be turned to sign, arbitrary steering cutting, so thin circular saw blades may easily "fatigue" (pending further study), the proposal with fixed to cut, we have adopted 4 years, the effect is very good.
Six, the current limit (overload) protection
Disk saw is in manufacturing process, can appear sometimes "bite saw" phenomenon, the serious influence matrix using life, especially thin circular saw blades, it matrix thin, "bite saw" unyielding, occurs when the matrix serious variant though can be back after leveling, but quality and life would have been affected. My company since 1997 LJA80 limited development and production flow controller, this product can be according to your needs, control motor current, more than you need when motor current, it can in 0.5 seconds control motor rose to rise, when you need when the current, it will automatically stop rising, so it can automatic protection diamond thin circular saw blades, and won't because current small and downtime, always won't "bite saw", can make the thin circular saw blades service life more than double.
