How they are Made & Their Application
Learn everything you wanted to know about resin bond diamond tools. How they are made, what types are available and their application
Resin Bond is an organic bond matrix that is formed by high pressure and high temperature. Phenolic resin is used as the bonding agent in majority of resin bond diamond tools. This bond is typically cured at temperatures of 150 to 200 degrees Celsius. Resin Bond is the softest of all the bonds, frequently used in applications that require a smooth surface. This type bond system that is used on majority of grinding applications on large variety of materials. Resin Bond Diamond Matrix promotes faster bond wear, allowing for diamond particles/crystals to break out of their matrix faster, so that new sharp diamond particles become exposed.

This self sharpening characteristic of resin bond matrix, based on faster bond wear is what make this blade an excellent choice for large variety of hard and brittle materials. Primary advantage of this bond type is Minimizing Chipping, and in majority cases elimination of secondary finishing operation (grinding/polishing or fire polishing).
Recommended for applications where cut quality and surface finish is very important. Compared to their sintered (metal bond) counterparts. Resin Bond Diamond & CBN offer far superior surface finish than any other bond type.
Application Range: cutting, grinding and polishing hard, brittle or delicate materials and where low heat generation or improved surface finish is desired. CBN, Resin bond Tools are recommended for cutting and grinding hard steels above Rc 60 at high speeds.
Example of Applications Resin Bond Diamond Tools are Used:
- ceramics
- glass tubing
- optical glass
- carbides
- composites
- semiconductor materials
- magnetic materials
- exotic metals
Best Cut Quality & Surface Finish
Recommended for applications where cut quality and surface finish is very important. Compared to their sintered (metal bond) counterparts. Resin Bond Diamond & CBN offer far superior surface finish than any other bond type. Recommended cutting, grinding and polishing hard, brittle or delicate materials including ceramics, glass tubing, optical glass, carbides, composites and exotic metals where low heat generation or improved surface finish is desired. Must be used at higher speeds. CBN, Resin bond Tools are recommended for cutting and grinding hard steels above Rc 60 at high speeds.
Its hardness, wear, heat resistance, diamond crystal retention and lubrication is controlled by use of various fillers organic and inorganic (usually ceramic or other metallic powders). Resin bond is low on Youn's modulus, this gives it the free cutting characteristics for which this bond family is known. These properties is what gives this bond the fast cutting speeds, superior surface finish, and minimal chipping. Resin bond diamond tools are used at higher speeds, the most other bond families. Resin bond diamond tools have shorter wheel life because the bond is much softer and brittle, and hence is not able to hold the diamond crystals in place as strong as its sintered (metal bond) counterpart.
Diamond Type Used for Resin Bond Diamond Tools
The diamond and CBN crystals used for resin bond wheels are different from those used for metal bond as well. Diamond Crystals used for resin bond are frequently polycrystalline, low strength, metal clad diamond crystal. They are irregular-shaped and easy to micro fracture. This creates new cutting edges constantly while cutting, giving the self sharpening characteristic for which resin bond is known. Often metal coated and unevenly shaped diamond crystal is preferred in manufacture of this bond type as it helps further improve crystal retention. Resin Bond Diamond Tools are typically used with coolant, but can also be used dry on many applications. By adding specializes filler and/or using specialized coated diamond crystal to reduce heat generation.
Resin Bond Diamond Tools Composition
majority of resin bond diamond tools are based on either phenolic resins or thermally table phenol aralky resins. They are used in form of very fine powder which accounts from around 30 to 40 wt % of the bond in dry and wet diamond wheels. To impart strength to the bond, the resins are mixed with alumina oxide of silicon carbide filler. Various oxide base drying agents, graphite or polytetrafuoor-ethlene lubricants, as well as aluminum, copper or silver powders are also added in small amounts in order to reduce and dissipate the frictional heat generated in cutting.
How Resin Bond Diamond Tools are Manufactured
Optionally, the mix may be hot pressed directly onto the tool hub which has undercuts on its circumstance in order to aid mechanical keying. diamond pending of the tools specification the diamond concentration may range from 50 to 125 (12.5 to 31.25 vol %). Most resin bond diamond tools utilize metal clad diamond which possess improved retention and heat dissipation characteristics as compared with unclad diamond. The metal cladding options are nickel base alloys, copper or silver, nickel clad diamonds containing 30 to 60 wt% nickel alloy, may have a rough spiky surface which aid diamond retention in the bond under severe cutting conditions.

Methods are an extension of human capabilities including a lever to promote interpersonal development and progress.
Fifty prohibited, people were struggling to figure out ways to change the difficult and inefficient labor while in the hard and brittle fabric processing industry.
As far as product positioning is worried, the diamond tool sector is roughly divided into your professional market and the overall market.
The requirements belonging to the professional market for gem tools are mainly reflected inside higher performance indicators, which is, for specific cutting tools and specific cutting products, diamond tools must satisfy certain technical indicators including cutting efficiency, cutting lifestyle, and processing accuracy.
Diamond is hard, so the tools made are particularly worthy of processing hard and brittle resources, especially non-metallic materials, including stone, wall and terrain tiles, glass, ceramics, cement, refractory materials, magnetic resources, semiconductors, gems, etc.
At found, diamond tools have been traditional in industries such seeing that construction, building materials, petroleum, geology, metallurgy, equipment, electronics, ceramics, wood, plus automobiles.
