12000 rpm angle grinder wholesale from China Manufacturer

RP-AG-88507L the rotating speed is 12000 rpm angle grinder. The no-load speed of the Angle mill is between 6000r/min-12000r/min, and the rated speed is 6000 RPM. The speed of the Angle mill is related to the specifications, and different specifications have different speeds. Because different specifications of the Angle grinder installed with different grinding wheel, in order to safety, technical safety requirements of any Angle grinder grinding wheel outer diameter linear speed does not exceed 85M/S, so according to this can be calculated the speed of different specifications of the Angle grinder.

Common models of Angle grinding machines are divided into 100 mm (4 inches), 125 mm (5 inches), 150 mm (6 inches), 180 mm (7 inches) and 230 mm (9 inches) according to the specifications of the accessories used, and the small-size Angle grinding machines used in Europe and the United States are 115 mm.

Descriptions about Angle Grinder

The speed of the low-speed Angle mill is generally between 3000 and 5000 revolutions per minute.
First, the advantages of low speed Angle mill
The speed of the traditional Angle mill is generally more than 10,000 revolutions per minute, such a high speed is easy to lead to splashing and cracking, as well as causing cutting marks on the surface of the workpiece, and it is not safe enough to use. Therefore, the low-speed Angle mill has gradually become a safer and more efficient cutting tool.

The speed of the low-speed Angle mill is usually between 3000 and 5000 revolutions per minute, which is much lower than the traditional Angle mill. Such a speed makes the low-speed Angle grinder have the following advantages:

Safer: the cutting force of the low-speed Angle mill is more uniform, and it is not easy to splash and break, reducing the occurrence of accidents.
More stable: the cutting accuracy of the low-speed Angle mill is higher, and it is not easy to slip, penetrate and wear, which is conducive to protecting the quality of the workpiece surface.
More environmentally friendly: The cutting noise of the low-speed Angle mill is smaller, and the dust pollution is less, which reduces environmental pollution and occupational hazards.
More energy saving: Low speed Angle mill has lower energy consumption, longer service life, reducing maintenance costs and energy expenditure.

Second, the difference between low speed Angle mill and traditional Angle mill
In addition to the difference in speed, there are some other differences between low-speed Angle mills and traditional Angle mills:

Cutter shape: The low-speed Angle grinder usually uses a fan cutter and a corner cutter, while the traditional Angle grinder uses a disk cutter. This design is conducive to the low speed Angle mill to maintain a more stable and uniform force, improve the cutting quality and efficiency.
The difference in weight: the low-speed Angle mill is usually lighter than the traditional Angle mill, which is more flexible and comfortable for workers to use.
The range of cutting materials: Low-speed Angle mills are usually suitable for harder materials, such as metals and ceramics, while traditional Angle mills are more suitable for the cutting of soft materials such as wood, plastic and rubber.

Third, how to choose a low-speed Angle grinder

Choose brands: Choose some well-known and reputable brands, such as Bosch, Miller, etc., to ensure product quality and after-sales service.
Purchase equipment: Select the appropriate cutter shape, cutting materials, power and speed parameters according to the needs, in line with their own needs and economic affordability.
Check the safety protection: check whether the safety protection device of the low-speed Angle mill is complete and effective to avoid accidents.

In short, the low-speed Angle mill has a wide range of applications in industrial production and personal maintenance, and its low-speed advantages make it safer, environmental protection and energy saving, worth promoting and applying.

The main distinction between the two is that an angle grinder is a handheld, portable tool, whereas a disc grinder is a sturdy piece of machinery. A disc grinder is typically used for precision work on smaller workpieces, whereas an angle grinder is used for rough cutting and grinding.

A cut off tool can only be used for cutting, whereas an angle grinder provides you with cutting, shaping, sharpening, grinding, and other functions. A cut off tool can be easily operated with one hand, while the angle grinder requires both hands.

Angle grinders get their name from the disc’s placement at a right angle to the handle’s axis. A safety guard casing is placed around the grinding discs to protect the worker’s eyes and prevent grinding sparks from striking his face.

Additional safety warnings for abrasive cutting operations

a) Do not “jam” the cutting wheel or apply excessive pressure. Do not attempt to cut too deep. Applying too much stress to the wheel increases the load and the susceptibility of the wheel to twisting or binding at the cut, and increases the likelihood of recoil or wheel breakage.
b) Do not align your body with and behind the rotating wheel. When the wheel leaves the body at the operating point, the possible recoil may push the spinning wheel and power tools directly towards you.
c) When the wheel is bound or the cutting is interrupted for any reason, turn off the power tool and keep the power tool still until the wheel is completely stopped. Do not attempt to remove the cutting wheel from the cut while the grinding wheel is in motion, or a recoil may occur. Investigate and take corrective action to eliminate the cause of wheel adhesion.
d) Do not restart the cutting operation on the workpiece. Allow the grinding wheel to reach full speed, then carefully re-enter the cut. If the power tool restarts in the workpiece, the grinding wheel may bind, walk, or recoil.
e) Support plates or any over-sized workpiece to minimize the risk of wheel extrusion and recoil. Large workpieces tend to sag under their own weight. Supports must be placed near the cutting line and near the edge of the workpiece on both sides of the grinding wheel.
f) Use extreme caution when making “pocket cuts” to existing walls or other blind areas. Protruding wheels may cut gas or water pipes, electrical wires or objects that may cause recoil.
