Alloy Saw Instructions
(A) Basic requirements:
1. Press the design of the equipment required to select the appropriate blade.
2. The equipment should be equipped with safety devices, such as: shields, power brakes, overload protection.
3. There are professional operators to install and use, and wear work clothes, wearing goggles, earmuffs and so on.
The operator can not wear gloves, long hair to be placed in the work hat, tie and cuffs and attention, to avoid any danger.
5. Keep away from fire and humid environment.
(B) the installation requirements:
1, the equipment in good condition, the spindle no distortion, no path jump, fixed solid, no vibration.
2. Check the blade for damage, the tooth is complete, saws is flat and smooth, and presence of other anomalies, in order to ensure safe use.
3, when assembling the blade determine the direction of the arrow in line with the direction of rotation of the spindle apparatus.
4, when the blade is installed to keep the spindle clean chuck and flange, flange inside diameter of the inner diameter of the blade is consistent with ensuring the flange and the blade closely, installed dowel pins, tighten the nut. The size of the flange to the appropriate outer diameter shall be not less than 1/3 the diameter of the blade.
5, before starting the device, ensuring the safety of the situation, a single person to operate the equipment, jog idling, check the device rotation is correct, with or without vibration, the blade installed after the first few minutes idling, no slippage, swinging or jumping back to normal the work.
(C) requirements:
1, in operation, the workpiece should be fixed to ensure the profile positioning in line with the direction of cutting tool, in order to avoid abnormal cut, do not apply lateral pressure or curve cutting, smooth feed to avoid the impact of the blade contacts the workpiece, thereby causing the blade to damage, or piece flying, accident.
2, in operation, found abnormal sound and vibration, cutting surface roughness, or odor, you must terminate the job immediately, timely inspection, troubleshooting to avoid accidents.
3, at the beginning of cutting and stop cutting, do not feed too fast to avoid broken teeth and damaged.
4. If cutting aluminum or other metal, use a dedicated coolant to avoid overheating the blade, resulting in tooth paste, and other damage, affecting the cutting quality.
5, the flute and suction equipment to ensure the smooth flow of the slag means to prevent the accumulation of slag into blocks, affecting production and safety.
6, when dry cutting, please do not long continuous cutting, so as not to affect the service life and the effect of cutting blade; wet sheet cutting, cutting water should be added, to guard against leakage.
(Iv) blade maintenance:
1. Saw If not used immediately, it should be flat or take advantage of the hole to hang up, or other items can not be stacked on flat foot blades, and should pay attention to moisture, corrosion.
2. When the blade is no longer sharp, cutting surface roughness, promptly re-grinding. Grinding can not change the original angle, and destruction balancing.
3. Correction inner diameter of the blade, the positioning hole processing, must be performed by the manufacturer. If the process is bad, it will affect the product effect, and may be dangerous, reaming principle it can exceed the original aperture 20mm, so as not to affect the balance of stress.
The alloy wheel choices.
1) resin bond diamond wheel bonding strength is weak, and therefore self-sharpening grinding to get better, clogging, high grinding efficiency, low grinding force, grinding temperature is low, the disadvantage is the poor wear resistance, abrasive wear and tear Great, is not suitable for heavy-duty grinding.
2) vitrified diamond grinding wheel wear resistance and superior binding resin binder, cutting sharp, high grinding efficiency, easy to heat and clogging, thermal expansion is less easily controlled precision, the drawback coarse grinding surface, higher costs .
3) high metal-bonded diamond grinding wheel bond strength, wear resistance, low wear, long life, low grinding costs, can withstand a greater load, but sharp difference, easy to plug.
4) abrasive wheel size has to cut the amount of blockage and to some extent, coarse sand and fine sand in comparison, plunging depth large abrasive wear of the cutting edge increases, on the contrary tend to clog the wheel.
5) Wheel hardness greater impact on the clogging, high hardness, high thermal conductivity of the wheel, is not conducive to surface cooling, but help to improve the precision and durability.
6) the concentration of choice is an important characteristic of the grinding wheel, the grinding efficiency and processing costs it has a great influence, affect the efficiency of the concentration is too low, whereas abrasive grains easily fall off, but the best combination of optimal concentration range.
