Saw blade 10 to embodiment 1 carries out following performance test:
Embodiment 1 saw blade 10 is as test example 1, is superhard alloy and other condition saw blade identical with the present embodiment saw blade 10 as a comparison case 1 and select AB flute profile, cutter tooth material.
One, cutting abrasion test.
Test example 1 saw blade and comparative example 1 saw blade are arranged on respectively on identical saw blade cutting machine and are cut, measure the wear extent of cutter tooth separately and cutter tooth periphery cutting blade.What be wherein cut material selection is the WPC material that weight fraction consists of 50% wood powder, 50% resin.
1.1 cutter tooth abrasion conditions.
No matter be test example 1 or comparative example 1, machining condition is identical, and its medium speed is 5000rpm, and the speed of sending into is 2m/min, cutting quantity 0.5mm.The measurement result of cutter tooth wearing and tearing is shown in Fig. 8.As shown in Figure 8, along with the increase of cutting distance, it is very fast that the wear extent of comparative example 1 saw blade cutter tooth increases, amplification is less for the wear extent of test example 1 saw blade cutter tooth, change comparatively steady, and identical cutting distance, the wear extent of comparative example 1 saw blade cutter tooth is much larger than the wear extent of the present embodiment saw blade 10 cutters tooth.
1.2 periphery cutting blade abrasion conditions.
Under identical machining condition, test example 1 is also that embodiment 1 saw blade 10 used after 3 months, as shown in Figure 9, the wear extent of cutter tooth periphery cutting blade is 0.1mm, can also continue to use, and comparative example 1 saw blade to use after 1.5 days cutter tooth periphery cutting blade wear extent as shown in figure 10 be 0.2mm, cannot continue use.The cutting quantity of visible the present embodiment saw blade increases to 50 times of comparative example 1 saw blade, and wear extent is only its half, and greatly extend service life.
Above-mentioned cutting abrasion test shows: the special flute profile design of the utility model and cutter tooth adopt the adamantine saw blade of many crystallizations, obtain long service life thereby can better suppress wearing and tearing with respect to the saw blade of traditional AB flute profile, superhard alloy cutter tooth.
Because greatly extend the service life of the utility model saw blade, although therefore its price is higher, but consider number of times and the life-span that can grind again use, its use cost remains decline with respect to the saw blade of traditional AB flute profile, superhard alloy cutter tooth, and cost is subdued rate (=the utility model saw blade cost/traditional round saw blade cost * 100%) even can reach 77%.
Two, cutting noise, cut-out power and section quality test.
To use embodiment 1 saw blade 10 after 3 months as test example 2, and comparative example 1 saw blade and test example 2 saw blades are arranged on respectively on same saw blade cutting machine, 1. survey from saw blade cutting machine 500mm place and cut noise; 2. measure current value and by computing formula, cut-out power is scaled to power; 3. measure section rugosity.
No matter be test example 2 or comparative example 1, the condition of cutting test is: rotating speed 1300rpm, and manually to send into and be cut material, the speed of specifically sending into is 0.3m/min.In addition, the cutting test of above-mentioned two kinds of saw blades is also carried out respectively in following three kinds of situations: 1. select 40H × 70W, middle for solid WPC angle section is as being cut material, 2. select 25H × 150W, middle for hollow WPC section bar is as being cut material, 3. idle running.Wherein the constituent that is cut material used is all identical.
Test result is as follows:
2.1, as shown in figure 11, compared with comparative example 1, test example 2 when idle running reducing noise 3dB, when cutting angle section, reduced 4dB, when cutting section bar, also decrease.In addition, after tested, noise level when noise when test example 2 dallies and saw blade cutting machine are not installed saw blade is suitable.Thus, use the utility model saw blade, can greatly reduce idle running noise and cutting noise.
2.2, as shown in figure 12, compared with comparative example 1, test example 2 difference on power (mean value) in the time of idle running, cutting angle section and section bar is all little, but the load relevant to cut-out alleviated.
2.3, as shown in Figure 13-14, test example 2 is used the state after 3 months as the utility model saw blade 10, is still better than the section quality of comparative example 1 saw blade according to its section quality of section rugosity.In addition, also record, compare ratio 1, between the side vibration of test example 2 saw blades and cutter tooth, knife mark is also less.
Be enlightenment according to desirable embodiment of the present utility model above, by above-mentioned description, related personnel can, not departing from the scope of this invention technological thought, carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine technical scope according to claim scope.
