Diamond Sintered Grinding Head

China Zhongyeda's diamond sintered grinding head is widely used in the stone processing industry for cutting, grinding and polishing of stone; in glass processing, it can be used to chamfer and grind the edges of glass; in the field of jewelry processing, it can finely grind gemstones; in mechanical manufacturing, it is also often used for surface treatment of cemented carbide parts, etc., and is an indispensable high-quality tool in many processing scenarios.

Diamond sintered grinding head is a high-performance grinding tool. The following is a detailed introduction to it:

1. Product Overview

Diamond sintered grinding head is a grinding tool made of diamond micropowder and metal powder as the main raw materials through a high-pressure and high-temperature sintering process. It has the characteristics of high hardness, long service life, high grinding efficiency, and not easy to wear, so it has been widely used in high-speed processing, precision processing, superhard material processing and other fields.

2. Main raw materials and production process

Main raw materials:

Diamond powder: key raw material, uniform particles, high crystal integrity, low impurity content, ensuring the hardness of the grinding head and uniform particle distribution.

Metal powder: Cobalt, nickel, iron and other metals are usually selected as binders for diamond powder.

Lubricant: It plays a lubricating role in the production process and helps to mix the raw materials evenly.

Production process:

Demolding: Chemical demolding or mechanical demolding methods are used to ensure the accuracy and surface finish of the grinding head.

Sintering: The core link, under high temperature and high pressure conditions, diamond powder and metal powder are pressed and formed to form a uniform sintered body with diamond particles and metal. The sintering temperature is generally between 1300℃ and 1600℃, and the sintering time is generally from several hours to one day.

Polishing: Polish the sintered grinding head to ensure the polishing effect and surface finish.

3. Product Features

High hardness: The combination of diamond micropowder and metal powder makes the grinding head extremely hard, suitable for processing various hard materials.

Strong wear resistance: The diamond sintered grinding head has a long service life and excellent wear resistance, which reduces the frequency of replacing the grinding head and improves processing efficiency.

High grinding efficiency: The diamond sintered grinding head has a fast grinding speed and can complete a large number of processing tasks in a short time.

Strong adaptability: It can be used to process various metals (such as steel, aluminum alloy, copper alloy, etc.) and non-metallic materials (such as marble, jade, glass, ceramics, etc.), and the processing hardness can reach a high level.

4. Product Application

Diamond sintered grinding heads are widely used in the industrial field and can be used for grinding, trimming and engraving various materials. For example, in stone processing, diamond sintered grinding heads can be used for carving, drilling and grinding inner holes of marble, bluestone, sandstone, quartz stone and microcrystalline stone; in metal processing, they can be used for precision grinding of metals such as steel, aluminum alloy and copper alloy; in addition, they can also be used for grinding and finishing of glass, ceramics, gemstones, semiconductors, magnetic materials, rubber and resin composite materials.

5. Product specifications and shapes

Diamond sintered grinding heads are available in a variety of specifications and shapes to meet different processing needs. Common specifications include grinding heads of different diameters and lengths, and diamond abrasive grains of different particle sizes. In terms of shape, there are flat-headed cylinders, round-headed cylinders, pointed cones, nail-shaped, egg-shaped, spherical, umbrella-shaped, oblong, oblate, conical, jujube-shaped, butt-shaped, inverted trapezoidal, flame-shaped, trapezoidal, torch-shaped, peach-shaped, pointed-mouthed and other shapes, which can be customized according to processing needs.
