How concrete cutting

Concrete cutting is the use of water-cooled diamond wire saw cutting machine tracks or opening holes for concrete, demolition, construction speed, low noise, no vibration, good quality, there is no impact on the building structure, is substituted hammer, picks, artificial brazing construction machinery and other large shock hit most advanced technology.
1. Before starting, you should check the motor, the cable is normal, protective earthing, guards, blade meets the requirements, the installation is correct.
2, after the start, the first no-load operation, check the concrete cutting discs running direction, lifting is flexible, operation is abnormal, after everything is normal before operation.
3, cutting thickness should not exceed the specified mechanical factory.
4, to prevent card concrete cutting blades, wire saw and the like.
5, concrete cutting operation, when there is abnormal sound, should immediately stop inspection, troubleshooting before continuing operation.
6, cutting the size of concrete blocks should be strictly calculated.
7, after the operation, the body should be washed, dried sheet rope saw cutting emissions than tank water to recover the cable and store in a dry, well-ventilated place.

Concrete cutting blades process often arise use

1: The concrete cutting blade mounting hole is wrong, the blade can not be installed
2: According to the cutting depth requirements, do not know how much the choice of blade
3: The new blade cut does not go
4: The concrete cutting blades life is not long, suddenly tip wear, so that can not be used
5: Blade out tooth
6: blade slipping during use

Concrete cutting technology are there?

1 manual cutting. Manual cutting chisel; the more laborious, not very convenient.
2 circular saw cutting wheel. Cut with a diamond saw blade disc; this is mainly cutting walls and the road has two kinds of saw blades, concrete cutting wheels very good. Suitable for houses or roads transformation.
3 wire saw cutting. Diamond wire saw cutting; this advantage that grow as long as there is enough rope saw, how objects can be cut, such as mining cut, diamond wire saw strong Germany is also very good

Road cutting

Road cutting film is a cutting tools that is widely used in stone cutting, concrete cutting discs, panels cutting, new and old road cutting, machining marking, grooving and other hard and brittle materials, road cutting sheet mainly consists of two parts; The base body and Segment the base is the main support of the tip portion of the adhesive, and the tip is cut from the part during use, the tip will be in use and continue to consume, while the matrix is not, the reason why head can play a role in cutting because it contains diamond, diamond as the most hard substance, it is friction in the tip cutting objects to be processed while the diamond particles in the head by a metal wrapped inside.

Concrete cutting piece of construction requirements and safety measures

Concrete cutting piece of construction requirements and safety measures
1. Before starting, you should check the motor, the cable is normal, protective earthing, protective equipment, cutting discs meets the requirements, the installation is correct.
2, after the start, the first no-load operation, check the cutting disc rotation direction, lifting is flexible, operation is abnormal, after everything is normal before operation.
3, cutting thickness should not exceed the specified mechanical factory.
4, to prevent the card saw, wire saw and the like.
5, concrete cutting discs operation, when there is abnormal sound, should immediately stop inspection, troubleshooting before continuing operation.
6, cutting the size of concrete blocks should be strictly calculated.
7, after the operation, the body should be washed, dried saw wire saw, the remaining water discharge tank, to recover the cable and store in a dry, well-ventilated place.

Wheel hardness selection principle

1. The harder the workpiece, the softer the wheel.
2. The larger wheel contact with the workpiece surface, the softer the wheel selection.
3. The grinding and profile grinding wheels should choose harder to keep the wheel shape required accuracy.
Wheel hardness relationship 4. Select the particle size: the larger the size of the wheel, cut off wheel is to avoid debris blockage, generally choose a softer wheel.
5. workpiece material: When grinding non-ferrous metals, rubber, resins and other softer material should be used in a softer wheel

How to balance the wheel

Its work process: when the wheel rotates, the generator rotor coil rotates coaxially, since fixed stator field coil cutting wheel magnetic field lines produce alternating current through the rectifier, filter, voltage into a DC power is supplied to the control circuit inside the balance head and stepper motors. At this time, the balance of the head of internal microcontroller system reset, begins to detect the presence or absence of infrared control signals. When the host sends a control signal, via an infrared remote control so that the slave is received from the serial port to the control signal, the control signal from the operation of two stepper motors running control program output control, drive screw rotation causes and weights together nut movement, enabling automatic compensation for cutting wheel unbalance.

Brief Wheel

Wheel hardness is not abrasive wheel hardness, but a combination of abrasive hardness between. Divided into soft, soft, hard, hard few. Each is divided into several levels. Hard not falling abrasive grinding wheel, grinding swarf under easy to stick on the wheel, causing the surface burns; soft abrasive grinding wheels easy to fall off, do not burn the workpiece, but the wheel consumed faster.
In addition to the hardness of the wheel, the organizational structure was divided tight, in a total of 12 loose, tight structure difficult to heat.
According to what you said, you can then check the wheel speed is not low? Rotational speed of the workpiece is not high?
Wheel hardness of its particle size should be! As can be seen the rough grinding wheel the coarser particle size, appearance can be seen! Numerical models of wheel greater the finer for finishing or polishing off, the softer brittle! Easily damaged.

What is Wheel

grinding wheels is the most important one class abrasive. grinding wheel is to add a binder in the abrasive, the porous body through compacts made of dried and calcined because of different abrasives, binding agents and the manufacturing process, the characteristics of the wheel vary widely, so the grinding process quality, productivity and economy have an important impact. characteristic wheel is mainly determined by the abrasive particle size, binder, hardness, organize, shape and size and other factors
