Carbide saw blade is the most commonly used wood products processing and cutting tools, carbide saw the quality and the quality of processed products are closely related. Proper selection of reasonably carbide saw blades for improving product quality, shorten cycle times, reduce processing costs is significant. Optional carbide saw what to pay attention to? Contains tooth carbide saw blades, angle, number of teeth, blade thickness, blade diameter, carbide, etc. Most types of parameters that determine the processing capacity of GUSHI diamond polishing tools the saw blade and cutting. When you select the correct selection of the blade to blade parameters based on need.
Tooth, tooth commonly have flat teeth, Dou tooth, trapezoidal tooth, inverted trapezoidal tooth (Figure 1). Flat teeth the most widely used, mainly for ordinary wood sawing, this tooth is relatively simple, rough kerf, slotting process operating level during tooth formation can bottom. Dou teeth sawing kerf quality is better for cutting all kinds of wood-based panels, plywood. Trapezoidal tooth suitable sawing plywood, fire board, obtain higher cutting quality. Inverted trapezoidal tooth saw blade used in the bottom slot.
Zigzag zigzag angle is in the cutting position. Serrated cutting angle affects the performance results. Greatest impact is on the cutting rake angle γ, the angle α, wedge angle β. Rake angle γ is serrated cutting edge angle, the greater the cutting rake angle more brisk, rake angle generally between 10-15 °. After the angle is the angle between the machined surface of the sawtooth between its role is to prevent the serrations machined friction surface, the smaller the angle the greater the friction, the more smooth the processing products. After the general value of carbide saw blade angle 15 °. Wedge angle is derived from the anterior horn and posterior horn out (Figure 2). But the wedge angle is not too small, it plays a role in keeping the teeth, according to strength, heat resistance, durability degrees. The rake angle γ, the angle α, the wedge angle β of the three equals 90 °.
Jagged teeth, teeth more generally, the GUSHI concrete polishing pads more the cutting edge per unit time, the better the cutting performance, but required more and more carbide cutting teeth number, the price of the blade is high, but too dense serrated , the chip between the teeth becomes smaller, the heat is easy to cause the blade; sawtooth excessive addition, when the feed amount of mismatch, then cut per tooth is small, the friction will increase with the workpiece edge, the life impact of the blade . Typically tooth pitch 15-25mm, should be selected based on a reasonable number of teeth sawing material.
The thickness of the blade from the saw blade in theory, we hope the thinner the better, is actually a kerf consumption. Materials and manufacturing processes carbide saw blade sawing board determines the thickness of the blade. To consider when selecting blade thickness from work and the stability of the blade sawing materials. Diameter and thickness of the blade used for cutting and sawing equipment related artifacts. Blade diameter is small, the cutting speed is relatively low; blade diameter saw blade and GUSHI metal grinding wheel cutting equipment requirements will be higher, while cutting efficiency is high profile, angle, number of teeth, thickness, diameter, species such as a carbide combination into a whole series of parameters hard alloy saw blade, and with a reasonable choice in order to better play its strengths. Various parameters carbide saw blades should be added choose? Carbide saw blade manufacturing companies can not do so many specifications saw, according to the law and according to the current preferred specific factors wood processing enterprises equipment, materials and other components of the current series of specifications used carbide saw blades. This helps us choose carbide saw blades, but also conducive to the alloy saw blade manufacturing enterprise scale production.

Diamond drill bit for drilling stone parameters
Drilling in stone, because of relatively high speed movement between
the diamond drill and stone complex tribological phenomena arising in
the contact interface. Friction GUISHI metal grinding wheel between diamond drill and stone, as the
stone poor thermal conductivity, most of the heat transferred diamond
segment, making diamond drill surface temperature, resulting in diamond
graphite, diamond cutting capacity reduced, which leads to the bit
matrix thermal fatigue, lower strength and stiffness, increased noise
when processing stone, increased vibration, reduce bit life, serious
diamond head off, causing injury to the operator, but also affect the
processing quality and efficiency. Research diamond bit drilling
parameters affecting its surface temperature to identify factors that
influence the relationship between surface temperature and the law,
determine a reasonable processing parameters, help to improve the
diamond drill bit life and reduce GUSHI stone polishing pads processing costs, improve processing
quality.
Experimental conditions
Using Cu-diamond tip metal powder, diamond particle size of 60 to 80
mesh, using pressing sintering method, the high speed steel cylinder
head welding. Diamond drill diameter φ37mm, high-5.6mm, width 2mm,
base diameter φ35.6mm, height 45mm. Processing equipment used XK5032C
type CNC milling machine, the device implements the X axis, automatic
feed three directions Y and Z axes, spindle cooling method using water
-cooled. The temperature measured with an infrared temperature
measuring surface of the tool, the measurement temperature range of -50
~ 650 ℃. Direct l2 ℃ measured at room temperature conditions. Stone
were selected marble, sandstone and granite. This experiment studies
the spindle speed, feed rate and stone impact performance parameters
such as surface temperature of the diamond drill bit. Experiment was
conducted under dry cutting conditions, machining state shown in Figure
1.
Analysis
3.1 feed temperature affects the speed of
When processing stone diamond drill, impact drill surface temperature
of many parameters, including diamond properties, performance bond,
stone physical and mechanical properties, processing parameters,
cooling parameters. Effect on the surface temperature of the diamond
drill bit experimental study of GUSHI concrete polishing pads stone processing parameters and
performance. Figure 2 is the spindle speed is 300r/min, the feed rate
was 10mm/min, 15mm/min, 20mm/min, 25mm/min, when the surface
temperature of the pre-drill drilling marble drilling time curve. As
can be seen in Figure 2, in the four kinds of conditions of feed rate,
the surface temperature of the diamond drill bits are increased with
the increase of the processing time. In the early stage of processing,
the temperature increases relatively slowly, when the processing time
exceeds 4s, sharp increase in temperature. When the processing time
reaches 10s, the diamond drill is the initial surface temperature 5
times. Figure 3 feed rate versus temperature curve for the processing
of marble. From the figure can be seen in the feed rate l0 ~ 20mm/min
the temperature rises slowly, the feed rate of 20 ~ 30mm/min, the
temperature rise is most obvious, the most heat in this interval drills
stone processing generated. As the drilling process, the diamond drill
bit with a large stone surface friction, resulting in diamond drill
surface temperature rise. Due to the low thermal conductivity of
marble, and a high thermal conductivity of the tool, a large part of
the heat conducted to the diamond drill bit, diamond drill causes the
surface temperature. Since the feed rate increases, the cutting face of
the contact per unit time increases, the number of cutter contact with
the stone, the surface temperature increases.
3.2 Effect of the number of revolutions of the spindle temperature
The feed rate of 15mm/min, spindle speed was 300rpm, 400rpm, 500rpm,
diamond drill bits and drilling the surface temperature of the time
when drilling marble curve. Overall, the temperature rises with
increasing linear time. Also can be seen from Figure 5, the temperature
increases with the spindle speed. However, the temperature rise is not
obvious. When the spindle speed reaches 500r/min, the maximum
temperature of 143 ℃. Increased spindle speed. Diamond particles to
increase the number of friction per unit time and stone, long exposure
time, thereby resulting in the surface temperature increases.
Effect of temperature on the surface properties of the stone
Spindle speed of 300rpm, when the feed rate is 15mm/min. Processing of
different stone diamond drill surface temperature averages. As can be
seen from Figure 5, when the diamond drilling granite surface
temperature reached a maximum of l50 ℃, while the lowest surface
temperature processing of sandstone, is 30 ℃; temperature during the
processing of marble is 70 ℃. Stone learned through performance,
granite density 2.5 ~ 2.7kg/cm3, the compressive strength of 120 ~
250MPa, marble density of 2.5 ~ 2.7kg/cm3, compressive strength of 47 ~
120MPa, sandstone density 2.2 ~ 2.5kg/cm3, compressive strength of 47 ~
120MPa. Three stone density basically the same, but far greater than
the compressive strength of granite, marble and sandstone, almost twice
the marble and sandstone. Stone intensity increased, the cutting forces
increase, diamond tool wear serious, leading to diamond drill the
surface temperature. Can be seen from Figure 5, the surface temperature
of the diamond tool machining granite processing time is 2 times
marble, sandstone five times. You can see from the processing of the
experiment, when dry cutting granite, diamond tool surface temperature
rises rapidly, while the high temperature, resulting in a diamond
cutter head off. Granite thermal conductivity 3.49W/mK, while the
thermal conductivity of copper is 370.49W/mK, it can be seen for most
of the heat is the heat conduction through the diamond drill, which led
to a sharp increase in the surface temperature of the diamond drill
bit, Diamond badly worn.
Conclusion
When using diamond drill bits manufactured stone, spindle speed and
drilling speed machining parameters a great influence on the tool
surface temperature. Tool surface temperature increase with spindle
speed and feed rate increases. Diamond drill surface temperature
increases with increasing drilling time, while time is proportional to
the drilling.

How to identify and saw the matrix do good piece burr cut big reason
Saw the matrix to identify how to do: Use a permanent marker to make the hole in the middle of the blade near the logo, after the device has a flange on the blocked will not be erased; using laser GUSHI core bits for concrete marking, such as fast peerless blade; most good is pneumatic marking. Hot rolled plate (plate oil must deformation) material production, saw tooth after punching hole and made a good fly how to remove the burr hole around the edges and tooth equipment and the way equipment with the center point of grinding (also called the hole grinder) it? Using simple equipment on bench below to make a base fixed. Tooth points glitches, buy a serrated grinding machine or by hand with a look. Why aluminum blade cut piece burr is always king, get a new blade also has a glitch, there is some kerf side has no burr burr side?
There are two effects:
Material: Soft hardness usually aluminum sawing down after glitches obvious, so you aluminum materials and state is not too soft
Sawing question: blade and cutting speed, cutting equipment usually used between 5000-6000 rpm, the problem is generally GISHI concrete diamond blades estimated that the blade is a 9-inch alloy saw Bosch ,60-70 yuan a piece, very durable Gold Fields is also available. Of course, if the condition can also buy Bosch circular saws, one to be in the vicinity of 1,000 yuan, 2100kw Bosch's encroachment up pretty good, at least much better than Rui Qi. Of course, you can also choose metal band sawing machine sawing advantage of small incision, less waste, while the cut is not as smooth, the disadvantage is the high price band, a small range of processing.

The main factors which affect the efficiency of the blade
First, the cutting parameters ( 1 ) Blade speed: in practical work , saw the line speed is equipment conditions , and restrictions were sawing blade quality stone before nature. From the best blade life and cutting efficiency , the linear velocity of the blade should be selected according to the different nature of the stone . When cutting granite , the blade may be within the selected line speed 25m ~ 35m / s range. For high quartz content and difficult cutting granite , remove the saw blade line speed limit is concrete diamond blades appropriate. In the production of granite tiles, using a diamond saw blade smaller diameter , the line speed up to 35m / s.
( 2 ) cutting depth : the depth is involved in diamond cutting wear , effectively sawing , saw the forces and the nature of the important parameters are affected by sawing stone . In general , when a high line speed diamond saw blade should be selected for cutting of small depth , from the current technology , the cutting depth of the diamond can choose between 1mm ~ 10mm . Usually large diameter saw blade when cutting granite blocks , cutting depth can be controlled within 1mm ~ 2mm between the feed rate should be reduced at the same time . When a large diamond saw blade line speed , you should select a large depth of cut. But in performance and tool strength saw the extent permitted , should try to take a greater concentration of cutting cutting to improve cutting efficiency. When the surface of the processing requirements of a small depth of cut should be used .
( 3 ) Feed speed : Feed speed Jibei stone cutting feed rate . Its size affect the rate of cutting , the blade and the cutting force by the heat dissipation area . Its value should be based on the nature of the stone sawing selected . In general, the sawing softer stone, such as marble, may be appropriate to increase the feed rate, if the feed rate is too low , more conducive to improving cutting rates. Sawing fine structure , relatively homogeneous granite , may be appropriate to increase the feed rate, if the feed rate is too low , diamond blade easily be polished . But while sawing UNEVEN coarse structure of granite , feed rate should be reduced , otherwise it will cause the blade vibration resulting in reduced fragmentation of diamond cutting rates. Granite cutting feed rate is generally within the range of the selected 9m ~ 12m/min .
Second, other factors a ) diamond size : diamond particle size in the common range of 30 /35 to 60/ 80. The more hard rock , should be selected with a finer granularity. Because under the same pressure conditions , the more detailed the more diamond sharp cut in favor of tile cutting blades hard rock . Further , the general requirements of a large-diameter blade cutting efficiency high , the particle size should be selected with a coarser , such as 30 /40 , 40/ 50 ; lower small-diameter blade cutting efficiency requires a smooth cross-section of rock cutting , should to a smaller particle size , such as 50 /60 , 60/ 80.
( 2 ) Segment concentration: the so-called diamond concentration , refers to the density distribution in the working layer of diamond carcass ( ie, the weight of the diamond contained within the unit area ) . "Norms " provides the carcass per cubic centimeter work containing 4.4 kt diamond , its concentration was 100%, with 3.3 karats of diamonds , its concentration was 75%. Represents the volume concentration of the volume occupied by the number of diamond agglomerates , and that, where a concentration of 1 /4 volume of the total volume of diamond is 100 %. Increasing the concentration of diamond is expected to prolong the life of the blade , i.e., reduced because of the increased average concentration of each piece of diamond cutting forces suffered . However, increasing the depth of the blade will increase the cost , so cutting discs there is a concentration of the most economical and the concentration increases with the shear rate increases VS .
( 3 ) the hardness of head binders : In general , the higher the hardness of the binder , the stronger its wear resistance . Thus, when a large rock cutting abrasive , hardness should be high binding agent ; when cutting soft rock material , the hardness of the binding agent should be low ; when sawing hard and abrasive rock large , the hardness of the binding agent should be moderate .
( 4 ) force effects, temperature effects and grinding damage : Stone cutting blade in the process , will be alternating load centrifugal force , cutting power, cutting fever. As the force and temperature effects caused by diamond saw blade worn donate damage .
( 2 ) cutting depth : the depth is involved in diamond cutting wear , effectively sawing , saw the forces and the nature of the important parameters are affected by sawing stone . In general , when a high line speed diamond saw blade should be selected for cutting of small depth , from the current technology , the cutting depth of the diamond can choose between 1mm ~ 10mm . Usually large diameter saw blade when cutting granite blocks , cutting depth can be controlled within 1mm ~ 2mm between the feed rate should be reduced at the same time .
