Diamond grinding wheels are widely used in the grinding of difficult-to-process metals with low iron content and non-metallic hard and brittle materials. They are suitable for grinding materials with a hardness of more than 50 degrees, such as cemented carbide, tungsten steel tools, high-aluminum porcelain, optical glass, agate gems, silicon crystal materials, magnetic materials, etc. Diamond grinding wheels are the most widely used and widely used type of grinding tools. When used, they rotate at high speed and can perform rough grinding, semi-finishing grinding and fine grinding, as well as slotting and cutting on the outer circle, inner circle, plane and various surfaces of the workpiece.
Application of diamond grinding wheels
Diamond grinding wheels have excellent grinding performance and are widely used in the grinding of difficult-to-process materials such as industrial ceramics, cemented carbide, optical glass, diamond tools, gems, etc. Diamond grinding wheels are extremely hard and difficult to dress. They are prone to clogging and other problems during use, which seriously affects the quality of the grinding surface and the dressing efficiency, limiting the application of diamond grinding wheels.
Dressing of diamond grinding wheel
Dressing of grinding wheel refers to the process of using dressing tools to shape the grinding wheel or remove the blunt surface to restore the grinding function and correct geometric shape of the working surface. Timely and correct dressing of grinding wheel is an indispensable and important link to improve grinding efficiency and ensure grinding quality.
Compared with ordinary grinding wheels, diamond grinding wheels not only have high grinding efficiency, small grinding force, and low grinding temperature, which can avoid surface burns and cracks of workpieces; but also have good grinding quality, high processing accuracy, low tool consumption, long life, and low processing cost.
Except for electroplated metal bond diamond grinding wheels, which generally do not require dressing due to their special manufacturing process, resin bond diamond grinding wheels, vitrified bond diamond grinding wheels, and metal bond diamond grinding wheels are all multi-layer abrasives. The precision of the grinding tool is determined by the dressing process, and the dressing quality directly affects its grinding performance.
Necessity of diamond wheel dressing
Grinding wheel dressing is the process of using dressing tools to shape the grinding wheel or remove the blunt surface to restore the grinding performance and correct geometric shape of the working surface. Because the insufficient cutting force caused by passivation and blockage, and the unevenness caused by wear will be directly reflected in the grinding results, timely and correct dressing of the grinding wheel is an important link that is indispensable for improving grinding efficiency and ensuring grinding quality.
Under what circumstances does the diamond grinding wheel need to be dressed?
1.Before using a new grinding wheel
In order to make the diamond abrasive grains on the surface of the grinding wheel exposed from the binder to form a cutting edge, the grinding wheel manufacturing does not achieve the ideal geometric size and accuracy; because the grinding wheel axis and the flange axis do not coincide, the abrasive tool axis and the grinding machine spindle rotation axis do not coincide, resulting in deflection.
2.During the use of the grinding wheel
Due to uneven wear, the geometric accuracy of the grinding wheel does not meet the use requirements; the working surface is blocked by grinding chips and cannot be cut normally; the surface diamond abrasive grains are blunted.
Function of diamond wheel dresser
During the grinding process, the abrasive grains of the grinding wheel gradually become rounded and blunted under the action of friction and extrusion, or when grinding tough materials, the grinding chips are often embedded in the pores on the surface of the grinding wheel, causing the surface of the grinding wheel to be blocked, and finally causing the grinding wheel to lose its cutting ability.
Diamond wheel dresser uses its shape recovery and cutting ability to dress planes, angles, arcs and combinations.
Principle of diamond wheel dresser
The working principle is to use the speed difference between the dressed grinding wheel and the dressing grinding wheel to achieve dressing. Generally, the consumption of silicon carbide grinding wheel is used to achieve the dressing of diamond grinding wheel or CBN grinding wheel.
The dressed grinding wheel is mainly installed on a precision cross slide, which can accurately control the dressing angle. The control accuracy of the feed axis is required to be 0.001-0.01mm, and it is also equipped with a 10-100 times magnification visual system for real-time processing monitoring and measurement.
Advantages of using diamond grinding wheel machine to dress grinding wheel
