The influence diamond buzz saw blade efficiency and also the life factor provides the saw to take the craft parameter as well as the diamond granularity, the density, cement degree of hardness and so forth.Based on cuts can count gets the saw blade line fast, the saw cuts the density along with the feed speed.

First, the saw cuts the parameter

(1) saw blade link speed: Within the practical work, the diamond buzz saw blade link speed receives kit condition, the saw blade quality and it is sawn cuts the stone only then nature the limit.Cut the efficiency in the best saw blade service life as well as the saw, should act based on the different stone material the nature choice saw blade link speed.If your saw cuts the granite, the saw blade link speed may designate inside 25m~35m/s scope.The granite cuts which concerning the quartz content high difficulty with saw, the saw blade link speed takes down the limiting value suitably for.When production granite face brick, the use diamond buzz saw blade diameter is small, the link speed may achieve 35m/s.

The (2) saw cuts the depth: The saw cuts the depth is requires the diamond abrasion, the effective saw cuts, the saw blade stress situation which is sawn cuts the stone material nature the important parameter.Generally speaking, in the event the diamond circular saw blade link speed is high, should select slightly cuts disappears the depth, from the present technology, the saw cuts diamonds the depth to become possible to choose from 1mm~10mm.Usually saws while using large diameter if your blade saw cuts the granite blank, the saw cuts the depth being possible to manage between 1mm~2mm, concurrently should reduce the feed speed.If your diamond circular saw blade link speed is big, should pick the big depth of cut.But works as with the power saw performance and the cutting tool intensity permission scope, should go ahead and take big cutting density to carry for the cutting as much as possible, enhances the cutting efficiency.When you should processes the top has got the request, then should make use of the small depth cutting.

(3) feed speed: The feed speed namely is sawn cuts the stone material the feed rate.Its size influence saw cuts rate, the saw blade stress and also the saw cuts the area light situation.Its value should act according to is sawn cuts the stone material the character to designate.Generally speaking, the saw cuts the soft stone material, if marble, but enhances the feed speed suitably, when the feed speed excessively is low, might be more advantageous in enhancing the saw to chop rate.The saw cuts the fine texture, the quite isotropic granite, but enhances the feed speed suitably, if the feed speed excessively is low, diamonds edge is smoothed easily by grinding.When though the saw cuts the macrometric structure the soft hard uneven granite, should reduce the feed speed, otherwise could cause the saw blade vibration to make the diamond disruption to reduce the saw to cut rate.The saw cuts the granite the feed speed to designate generally inside 9m~12m/min scope.

Second, other influence factor

(1) diamond granularity: Frequently used diamond granularity in 30/35~60/80 scope.The rock is harder, the perfect selection uses the thin granularity.Because under the same level pressure condition, the diamond is thinner sharply, pays to in cuts in the hard rock.Moreover, the typical large diameter saw blade request saw cuts the efficiency to get high, the perfect selection uses the thick granularity, like 30/40,40/50; The minor diameter saw blade saw cuts the efficiency is low, the request crag stone saw cuts the section for being smooth, selects the thin granularity suitably, like 50/60,60/80.

(2) tool bit density: The so-called diamond density, is refers to the diamond the density which distributes inside work ply tires body (is at unit area contains diamond weight).“standard ” stipulated, substantially each ml work carcass of tire contains 4.4 carats diamonds, its density is 100%, when including 3.3 carats diamonds, its density is 75%.The volume concentration indicated agglomerates the diamond to be the cause of the degree how many, and stipulated, when the diamond volume makes up the majority volume the 1/4 density is 100%.Boosts the diamond density to desire to lengthen the saw blade the life, because increased the density namely to relieve the typical cutting force which each grain of diamond received.But enhances the depth to enhance the saw blade inevitably the charge, thus features a most economical density, also this density in addition to cheng cuts rate increases increases.

(3) tool bit cement a higher level hardness: In most cases, cement penetration of hardness is higher, its anti-attrition ability is stronger.Thus, once the saw cuts the abrasiveness big rock, cement level of hardness suitable high; If the saw cuts the material quality soft rock, cement penetration of hardness suitable low; In the event the saw cuts abrasiveness big also the hard rock, cement level of hardness suitable moderate.

The (4) strength effect, the temperature effect and rub through damage: Diamonds buzz saw blade inside cutting stone material process, can obtain centrifugal force, the saw shearing force, the saw cuts alternating load and many others the heat functions.

Make the diamond buzz saw blade because of the strength effect plus the temperature effect to rub through contribute damage.

Strength effect: Cuts in the operation from the saw, the saw blade must have the axial force along with the tangential force function.On account of within the circumference direction plus the radial direction existing power function, causes the saw blade in axial to assume wavilness, assumes the little dish shape from the radial direction.The two of these type of distortions can cause the rock section not not straight, the stone material in a big way wastes many, the saw cuts in the event the noise, the vibration intensifies, creates the diamond to agglomerate the first breakage, the saw blade life reduces.

Temperature effect: The more common theory believed that,The temperature mainly displays to the saw blade process influence by 50 percent aspects: One, causes to agglomerate the diamond graphitization; Two, creates the diamond along with the carcass of tire hot Luan strength causes the diamond pellet prematurely to fall away.The revolutionary research indicated that,Inside the cutting process produces the quality of heat mainly spreads agglomerates.The arc area temperature is not high, generally in 40~120℃ between.But an abrasive grinding temperatures are actually high, generally in 250~700℃ between.Nevertheless the refrigerant only cuts down on arc area the average temperature, affects actually for the abrasive temperature slightly.Such temperature does not make the graphite to carbonize, could cause between actually the abrasive as well as the work piece rubs the performance to improve, and causes between your diamond as well as the chemical additive contains the thermal load, but causes diamonds expiration mechanism to have the fundamentals curved.The study indicated that, the temperature effect is causes the saw blade breakage one of the most tremendous influence factor.

abrasive wear: the competitiveness effect plus the temperature must be less, and saw a short time in many cases are employed in abrasive wear. abrasive wear around the main form can be purchased in the subsequent: abrasive wear, partially large torn, split up, fall off, along with cutting speed of mechanical abrasion. abrasive wear: diamond particles-to-edge constant friction, chemical surface passivation and lose their cutting performance, increase friction. Cut the heat will always make diamond particles occur on the outside of thin graphite, hardness greatly reduced, increased wear surface: diamond particles to face up to the thermal stress, as well as withstand the strain of cutting, the fatigue cracks and partially broken, sharp edges from the new edge, can be a better with the wear patterns; a huge broken: diamond particles out of all constantly, sustain the impact load the more prominent particles and die prematurely consumed; off: To vary the cutting force in diamond particles, which is a loose weave. Meanwhile, cut the at the same time of wear and tear and cut with hot to soften. In this way, the dominate, when particles larger than the cutting force controlled, diamond particles will fall away. Irrespective of which one with diamond particles are worn by the load and temperature dependent. Both of which be based upon all workmanship in order to find cool lubricating conditions.
