Cause Analysis and Solution of Circular Saw Blade Damage

Common Damage Causes

The saw blade of circular sawing machine is often worn out or worn out too fast in many enterprises using metal circular sawing machines. This is a common problem, and it is also a headache for enterprises. So is there any way to minimize this loss?

Saw blade installed incorrectly

When installing the saw blade of the circular saw machine, it must also be installed correctly. Check it several times. Improper installation will not only break the saw blade of the metal circular saw machine, but also affect the service life of the circular saw machine;

Incorrect ampere setting

Incorrect setting of the ammeter can result in broken saw blades and damage to the machine

Circular saw machine cleaning work is not in place

Especially the iron filings inside, no matter how small the iron filings are if they are not cleaned up in time, it will increase the breakage rate of the circular saw blade and consume too much; The surface of the saw blade is not smooth enough, and the friction is increased.

Cutting too fast

The cutting speed is related to the material to be cut. The cutting speed of different materials should be adjusted in time according to the requirements. Many companies blindly adjust the cutting speed for fast cutting speed, resulting in damage to the saw blade of the metal circular saw, which is also the damage to the saw blade. The root cause; the material to be cut is relatively dirty. This situation is relatively rare. Some companies cut the material relatively dirty, and the company does not pay attention to it. Often, the material is directly sent to the machine for cutting, and the material to be cut is never cleaned first. It is a wrong consciousness, because there is a lot of dust, iron filings, and even dirt on the material, which will bring a lot of friction to the metal circular saw blade when cutting, and the friction circular saw blade will wear out too quickly;

The circular saw machine works for too long at one time

Usually, in order to speed up production, enterprises may work more than 12 hours a day, or even work 24 hours a day. In this case, the load of the circular saw blade will increase when cutting, the circular saw blade will not be buffered, and the wear will be too fast. Inevitably.

Knowledge about daily debugging of metal circular saw blades

If the metal circular saw blade is not adjusted correctly, the quality of the sawing workpiece will be unstable, and even cracked or chipped teeth will occur, including affecting the performance and service life of the equipment. Therefore, the correct adjustment of the metal circular saw blade is important for cutting equipment. very important.

Debug operation and process

First of all, clean the flange part of the equipment, maintain a good working environment, carefully check the direction of the metal circular saw blade, do not install it in reverse, you can look at the trademark on the circular saw blade, and the side with the trademark is facing up. , and tighten with the specified screws.

Wipe and clean the equipment and the required items, place them in the designated position, and ensure that they are locked with specific screws when debugging. After that, check whether there is any looseness. Pay attention to the position of the protective cover to ensure safety and prevent accidents; Clean and clean, after the operation, gently try to turn it down by hand to see if it is correct, to ensure that the rotation is smooth and there is no jamming phenomenon.

Special attention is that the wire brush of the metal circular saw blade must be adjusted accurately, otherwise there will be unforeseen failures! Covered by the sawtooth bag prevail.

When the equipment is in operation, the circular saw blade is rotating. After the power is cut off, there will be a rotation process. After the saw blade is completely stationary, you can touch it for replacement and debugging. Please make sure that the equipment is stopped and the saw blade is turned on after it is stationary. Saw blade cover, when replacing the saw blade, the power must be cut off first

About itinerary settings

The forward end of the equipment must be checked first, the proximity switch on the lateral clamping seat and the saw blade cover to ensure that all metal materials can be set accordingly, and the position of the backward end does not need to be adjusted, and the position of the rear end cannot be adjusted. Also fixed, can not be adjusted. (Note that this scale cannot be used for square or special-shaped steel, and the saw blade may be damaged according to this scale.) If metal cutting equipment needs to saw irregular materials, move to the switch position of the horizontal clamping, and screw Relax a little and adjust the fixing frame according to the actual situation. If the device is in operation, the LS sensor block cannot be adjusted at this time. Be sure to wait for the device to be completely stationary before debugging (please cut off the power supply at the same time), otherwise it is very easy to cause an accident.

About metal circular saw blade oil mist

The oil mist in the device is a non-edible liquid, and the average is about one drop every 10 seconds. If it accidentally enters the body, you must induce vomiting immediately. If the amount is too much, you should seek medical attention immediately; if oil mist enters your eyes during use, please immediately Rinse with plenty of water, and take protective measures to avoid freezing in winter or when the temperature is low.

Types of sawing machines

Vertical Band Saw:

The scope of work includes straight, angular and curved profiles. The saw blade is installed on two guide wheels arranged on the upper and lower sides. The upper guide wheel adjusts the tightness of the band saw machine, and the lower guide wheel drives the band saw blade.

Horizontal Band Saw:

The saw blade advances in the horizontal direction and is mainly used for material cutting.

Circular Sawing Machine:

Metal Circular Saw Machine: Use a large-diameter circular saw blade, rotate and feed close to the workpiece at the same time, cut the material and return to the starting point to prepare for the next working cycle.

Abrasive circular sawing machine: Using a thin grinding wheel as a tool, high-speed rotation produces a grinding effect, and the workpiece is sawed off.

Bow saw:

It has the advantages of simple structure, convenient operation and low maintenance cost. However, in the reciprocating stroke, only the outgoing stroke has a sawing effect, and the lower operating efficiency is its greatest advantage.

Universal sawing machine:

Qingxiang metal wire saw machine has precise structure design, simple operation, fast and stable cutting, flat cutting surface, high precision, the most economical saw band, wide processing surface, strong cutting force, and many models are suitable for all kinds of iron factories, molds factory use. Equipped with hydraulic feed and shape controller, straight line and multi-variable shapes can be cut freely, with stepless speed change.
