flat cutting disc Abrasive cutting machines

Abrasive cutting machines, also known as wheel saw, grinding wheel cutting machine is suitable for construction, metal, petrochemical, metallurgical and mechanical stainless steel cutting discs‍ installation of water and other sectors. Abrasive cutting machine can be flat metal square tube, square flat steel, I-beam, channel steel, carbon steel yuan, yuan pipe and other materials commonly used cutting equipment. 

Grinding machines, which is mainly the base wheel, electric motor or other power source, the carrier, water and the like protective cover composed of the grinding wheel is disposed on the top surface of the base, the base for accommodating therein a power source space, power source drives a reducer, reducer shaft having a top surface for piercing the base fixedly connected wheel, the wheel base has a bottom position corresponding to a depression in the catchment area, catchment area extending outward wheel cutting machine first-class road, water wheel is located on the top side, with a space containing liquid water within the water control and water supply corresponds side wheel has an outlet. stainless steel flap disc‍ Has a very streamlined to improve overall transmission mechanism, so that the grinding process smoother and easier to improve the overall performance of the grinding wheel machine effect. 

Wheel more brittle, high speed, should be used in strict compliance with safety procedures.‍

Vitrified diamond wheel with common characteristics diamond and ceramic binder:

Advantage 

① Compared with ordinary corundum, silicon flap discs carbide grinding wheels, grinding it strong, relatively low temperature grinding wheel wear is relatively small; 

② can be adapted to effect various cooling liquid; 

③ When the grinding wheel shape retention, high precision grind the workpiece; 

④ have more holes in the wheel, chip and heat favor grinding, clogging, easy to burn the workpiece; 

⑤ self-sharpening wheel better, longer intervals dressing, dressing easier. 

So vitrified diamond grinding wheel in tile granite cutting wheel‍ the increasing use of some foreign countries.

Applications Vitrified diamond wheel

With the development of science and technology, new materials is growing, machinery processing to high-quality, high-precision, high-efficiency, automation direction continues to develop, vitrified stone cutting wheel‍ bond diamond wheel increasingly wide range of applications, the amount of the increase. Vitrified diamond grinding wheel is mainly used in the wafer (semiconductor wafers and solar wafers), PDC, polycrystalline diamond, diamond tools, cubic boron nitride, tungsten steel (alloy), new engineering structural ceramics, precious stones , crystal, rare earth materials (magnetic) contour machining brittle materials, and achieved good economic benefits. 

PCD diamond tools are mainly concentrated in the composite films, chemical vapor deposition (CVD) single crystal diamond coated tools and knives and so on. Select reasonable parameters, vitrified diamond single crystal diamond grinding wheel, grinding efficiency than metal bonded grinding wheel wear ratio is very small, low cost, and therefore the use of vitrified grinding wheel single crystal diamond, can greatly improve Happening grinding efficiency. PCD grinding tool, since the binder resin is relatively soft, easily deformed grinding, grinding of PCD tools can be effectively; construction cutting blade‍ metal binder binding abrasive particles due to leaving too poor self-sharpening abrasive grinding low efficiency, and metal bonded grinding wheel edge will cause PCD tool generates the most serious damage; processing quality integrated grinding efficiency, durability and abrasive surface of vitrified diamond grinding wheel to select the most appropriate tool PCD . 

Fine-grained ceramic bonded diamond grinding tools for chrome hardened steel bearing rollers do precision machining dimensions. 

Vitrified diamond abrasive used for automobiles, tractors crankshaft, hydraulic gear neck to do precision machining. 

Has good toughness ceramic bond diamond wheel for television picture tubes blind sector do coarse and fine grinding. Vitrified diamond wheel with integrated high-performance silicon processing, high precision machining, machining roughness is low, and the grinding of silicon metal ion flap discs contamination, high pass rate of processed products.

flat cutting disc Diamond grinding wheel during use Precautions

Precautions

Side grinding problem

In everyday use grinders, we can often find some kind Tile cutting discs‍ of grinding machines, regardless of the operator, regardless of the type of wheel, optionally grinding wheel on the use of the side, which is a serious violation of safety rules in the illegal operation behavior. Made according to the rules with the circumferential surface of the side face of the grinding wheel should not be used, higher radial strength of this wheel, the axial strength is small, the grinding wheel can cause crushing injuries or excessive force when the operator, the actual the use of the process should prohibit such behavior.

Positive operating problems

In everyday use, many operators are facing the wheel always used to operate, because this direction can be put into effect, in fact, this behavior is the behavior of grinder operation should be particularly prohibited. Follow the rules, the use of grinders grind the workpiece, the operator should stand on the reinforced concrete cutting wheels‍ side of the wheel, the front wheel may not operate when the wheel to avoid a failure, or the wheel broken wheel flying flying wounding.

LEMAN metal cutting discs Force operational problems

When using the grinder, some operators, especially the concrete cutting blade‍ younger operators, for the sake of grinding speed, force too much too fast, this is a very unsafe behavior. Any wheel body has a certain level of intensity, this could cause the wheel broken, and even flying out of wounding, but also a should be prohibited.

Common operational problems

In the actual daily operations, but also this happens, someone to catch production tasks, rob working time, the two share a grinding machine while operating, which is a serious violation of operating behavior, should be strictly prohibited. A grinding machine is not enough time, can be used to add Tile cutting discs‍ grinders solution, and definitely not at the same time share a grinder.

stainless steel cutting discs Diamond saw

Diamond saw is a cutting tool that is widely used in the stainless steel cutting discs‍ processing of concrete, refractory materials, stone, ceramics and other brittle materials. Diamond saw blade is mainly composed of two parts; matrix and heads. The base portion of the main support of the bonding head, and the head is cut from the part during use, and, in use, the tip will be consumed continuously while the substrate is not, since the cutting head is able to effect because it contains diamond, diamond as the most hard material, it is the friction in the cutting head flat cutting disc‍ of the object to be processed. Wrapped by the diamond particles and the metal inside the head.

flat cutting disc Introduction A cutting tool

A cutting tool is a diamond saw blade, is concrete cutting disc‍ widely used in the processing of concrete, refractory materials, stone, ceramics and other hard and brittle material is mainly diamond blade consists of two parts: the base substrate and the head is the main support of the bonding head portion and the tip portion is cut from the cutter head in use and will be consumed continuously during use, the substrate is not, since the cutting head is able to effect because it contains diamond, diamond as the hardest substance, it is the object of friction stainless steel cutting discs‍ in the cutting head in while the diamond particles from metal powder wrapped in the head, commonly known as the head.

Process Classification

1, sintered diamond saw blades: two of cold and hot flat cutting disc‍ sintering sintering, pressing and sintering. 

2, welding diamond saw blade: laser brazing and welding of two types of high-temperature molten solder through the head and the substrate medium welded together, such as high-frequency induction brazing blades, vacuum brazing saw blades; Laser Welding a laser beam head by high temperature contact with the substrate forming a metallurgical bond edge fusion. 

3, plating (solder) diamond blades: the powder is attached to the head substrate by a plating method. In 2012, the state started to gradually abolish electroplated diamond products concrete cutting disc‍ in production, mainly because of the pollution is very serious.
