CNC slotting machine is mainly used for asphalt, cement pavement repair, drainage pipe, gas pipe, electric wire pipe and optical cable pipe. The road surface is quickly cut into uniform grooves by a rotary saw to form a new bonding surface. Optimize the contact level between the grouting material and the slot, and strengthen the tightness of bonding between the grouting material and the side wall of the slot. Let's explain the knowledge about CNC slotting machine for you, let's look down!

Features of CNC slotting machine

  

1.Dual-cylinder gasoline engine, super power can speed up construction speed and construction efficiency, avoid uneven slotting or breakage;

2. Equipped with patented dual filter and three-stage air filter device, the filter system adopts double-layer filter device and rotary blade filter to increase air purity, prevent the engine from sucking in dust, reduce engine wear, and effectively extend the engine. life;

3. The engine provides smooth power and reduces vibration.

4. The emergency stop switch of the quick stop system can effectively protect the operator. Press the stop switch lightly, the engine is turned off, and the tool stops rotating within 4 seconds.

5, 60w lighting for safe construction in dark weather;

6.Imported brand high-end maintenance-free battery with longer life and self-charging during work, more worry-free, more durable and faster;

7, the use of electric push rod can adjust the slotting tool lift; slotting depth indicator allows the construction staff to control the slotting depth according to needs.

8.Crack positioning and tracking indicator needle, to ensure the accuracy of the falling knife, so that the CNC slotting machine can accurately track and slot along the crack to avoid operating errors;

9. Splash-proof chain length: 140mm Splash-proof chain width: 330mm Dust-proof baffle size: 320 × 260mm, which can effectively prevent the debris from splashing during slotting operation and ensure the safety of construction work

Precautions for CNC slotting machine operation


1. Before starting the machine tool, you must carefully check whether the cutters, nuts and screws are firm. If you find any loosening, you must tighten it in time;

2. Pay attention to the cutting direction when installing the tool, and do not reverse it;

3.The main tool is turned clockwise;

4. Before feeding and grooving, first confirm whether the pneumatic device is turned on and press the workpiece on the movable platform and against the positioning plate, and the hand is not allowed to approach the knife edge;

5. When the machine tool breaks down, the power should be cut off immediately, and the operation should be stopped, and a special person should be repaired and adjusted. The machine tool is not allowed to run with disease;

6. Before processing the material, first check whether there are iron nails, sandstone joints, etc. on the cutter to prevent damage to the cutter.

7. The machine tool must be powered off when cleaning, rubbing lubricant, and removing saw blades and cutting debris.

8.The machine must be operated, adjusted and repaired by designated personnel. Those who are not familiar with the machine should not use it.

9, workers should wear ear protection, protective glasses and other labor protection supplies.

10. The maintenance of the machine shall be carried out according to the "Equipment Operation, Maintenance and Maintenance System".

The purchase of CNC slotting machine can refer to the following points


1. Be clear about the difference between manufacturers and sellers. Due to the large market demand for CNC slotting machines, 80% of the machines on the market are replicas of small workshops. These machines are ordinary accessories. This kind of product cannot be used for a long time, and it can't meet the process requirements of CNC slotting machines. After the purchase, it can't talk about any after-sale protection, causing great losses to buyers. The manufacturer operates its own brand, has its own unique technology, and strives for excellence in any production link, and will provide perennial technical support for the product.

2. See if the seller is a connoisseur. Many individuals and businesses buy wall grooving machines for OEM sales, but they know very little about the product itself, and even the advertising pictures are all misappropriation. Such businesses can be identified with a little care.

3. Has the merchant exaggerated the fact that the hydropower CNC slotting machine is not perfect, and some places have their own limitations. However, in order to sell products, some businesses will promise whatever guarantees are guaranteed. Falsely exaggerating the power of the CNC slotting machine, increasing the size of the slot, and some even say that it can open steel bars. For walls, encountering rebar will only damage the cutter head.

4. How about the company's reputation, whether there are any bad records, or even scam companies, these are not difficult to see in today's developed Internet.

5. When buying CNC slotting machines, be sure to shop around. Finally, make a judgment and don't buy blindly. Not only considering the price, but only choosing the right product, rest assured that it is the basis of making money.
