- Loss of tension
-
Symptom Cause Remedy There is “undercutting” when the steel plate wears more rapidly than the diamond segment, particularly at the joint between the segments and the steel plate. The blade is being used on a poorly aligned saw.
Correct the alignment of the saw. The blade is too hard in relation to the material being cut, which causes excessive stress on the steel plate. Ensure that the blade is suitable for the material being cut (consult the selection table or see your distributor).
Slippage of the material causes deformation of the blade which twists or bends.
Hold the material firmly while sawing. The use of flanges which are too small or not of the same diameter causes unequal pressure on the steel plate.
Ensure that the flanges are of the right size and the same diameter. The blade is poorly fitted onto the spindle and bends when the flanges are tightened.
Hold the blade on the spindle until the outer flange and the nut have been firmly tightened. The blade is being used at the wrong speed of rotation.
Check whether the spindle is rotating at the correct speed, using a tachometer. This precaution is particularly important for concrete saws.
The steel plate heats up due to friction caused by too rapid or uneven wear of the rim.
Use a blade with more side clearance or of a specification more suited to the material.
- Excessive Wear
-
Symptom Cause Remedy The blade used is not suitable for the highly abrasive material being cut (e.g: a tile-cutting blade used on a concrete block).
See the blade selection table or consult your distributor who will indicate the correct blade specification. Blade cooling is insufficient; this problem is often found because of excessive wear in the centre of the segment. (Note: in the two cases mentioned above, the diamonds generally project very sharply).
Clean the cooling system. Ensure that the water pump is operating correctly.
Wear accelerates if the blade has lost its circular shape; this may be due to poor bearings, a worn spindle or the use of a blade which is too hard in relation to the material being cut.
Check the bearings and the spindle. If they are worn, replace them before fitting a new blade. Output power is insufficient because V-belts are not properly tensioned, voltage is inadequate or speed is incorrect.
Tension the belts correctly. Replace worn belts. Check the voltage. Use an appropriate power source. Cutting speed is too fast.
Reduce the speed of advance. Blade is not perpendicular to the material being cut.
Check the speed of the blade’s drive spindle and the flanges to ensure correct alignment of the blade and of the machine.
Spindle is rotating too slowly.
Check the speed of the drive spindle. If necessary, change the equipment or modify speed of rotation.
How to choose the saw blades
The Max. rpm of the saw blade should be changed according to the cutting diameter and the plate. Refer to the table 1. If the rpm is higher than the data, it will influence the performance and shorten the cutting life of the blade. The T must be higher than the teeth top, refer to picture 1, too much or less will lower the quality of the blade.
The working teeth number must be 3 or 4. Refer to picture 2. If less than 3, it will cause the vibration and can't get a smooth cutting face. If you want to cut thicker stock but use the same diameter blade, then choose the small number teeth blade. For the same diameter blade, if you want to cut thinner stock with longer cutting life, choose the larger number teeth blade.
Key
P=pitch
S=the thickness of the work piece
Z=teeth number
D=cutting diameter
remark:
The above formulation is used to for cross cut, or cutting MDF, plywood, chip board or laminate, not for rip.
How to choose the dimensions
1.P=Sx1.4142/3
2.Z=Dx3.14/P
3.Z=Dx8/S
How to use the saw blade
1.Make sure about the precision of the guide and principal axis.
2.The size of the flanges inside or outside must be same, the flanges must be clean, flat.
3.Clean the saw blade before using, make sure the contacting surface with the flange must be non-rusty and clean.
4.Make sure about the right running direction. Make sure the fixing is tight enough.
5.Re-sharpen the blade regulary. Do not use the blade immoderately. Make sure about the cutting angles during re-sharpening.
6.Clean the body and the tips before re-sharpening.
7.Choose the right grinding when re-sharpening (grain, hardness), make sure about the sharpness and prevent the tips from chipping. Use the cooling liquid.
8.When enlarge the bore, do not enlarge the bore size 20mm larger than before. Check the section run out at the diameter, prevent the blade from off-centre and then lower the quality. Do not enlarge the bore size on plank multi-rip saw.
9.Please use the CNC grinding machine to re-sharpen the blade. Do not use hand control, prevent from accident.

- 数控刀具的加工顺序的安排应遵循什么原则？
-
加工顺序的安排应根据零件的结构和毛坯状况，以及定位夹紧的需要来考虑，重点是工件的刚性不被破坏。
顺序一般应按下列原则进行：
(1)上道工序的加工不能影响下道工序的定位与夹紧，中间穿插有通用机床加工工序的也要综合考虑。
(2)先进行内形内腔加工序，后进行外形加工工序。
(3)以相同定位、夹紧方式或同一把刀加工的工序最好连接进行，以减少重复定位次数，换刀次数与挪动压板次数。
(4)在同一次安装中进行的多道工序，应先安排对工件刚性破坏小的工序
- 数控刀具中如何对加工工序进行划分
-
数控加工工序的划分一般可按下列方法进行：
（1）刀具集中分序法 就是按所用刀具划分工序，用同一把刀具加工完零件上所有可以完成的部位。在用第二把刀、第三把完成它们可以完成的其它部位。这样可减少换刀次数,压缩空程时间，减少不必要的定位误差。
（2）以加工部位分序法 对于加工内容很多的零件，可按其结构特点将加工部分分成几个部分，如内形、外形、曲面或平面等。一般先加工平面、定位面，后加工孔；先加工简单的几何形状，再加工复杂的几何形状；先加工精度较低的部位，再加工精度要求较高的部位。
（3）以粗、精加工分序法 对于易发生加工变形的零件，由于粗加工后可能发生的变形而需要进行校形，故一般来说凡要进行粗、精加工的都要将工序分开。 综上所述，在划分工序时，一定要视零件的结构与工艺性，机床的功能，零件数控加工内容的多少，安装次数及本单位生产组织状况灵活掌握。另建议采用工序集中的原则还是采用工序分散的原则，要根据实际情况来确定，但一定力求合理。
