product constract
Hans diamond Flexible grinding and polishing tool is composed of three main elements: Diamond , bonding and backing. The multiple combinations of these elements provide the highest efficiency to meet the diversified requirements of industrial grinding and polishing .
Diamond is composed of carbon with crystal structure. For grinding tools, the Diamond used is usually synthetic and produced under high temperature and pressure. Diamond particle size data based on average particle size( μ m). Coarse Diamond will increase the material removal rate and surface roughness of the workpiece. The choice of the appropriate particle size depends on various factors: application, material, drive, wet grinding (water, abrasive) or dry grinding (wet grinding is generally used).
Grain size range
All grain sizes have corresponding color codes, which can be selected: 251 µ m (60 – 80), 126 µ m 120), 91 µ m 180, 64 µ m 240 – 320, 46 µ m 400, 30 µ m 600, 20 µ m 800, 15 µ m 1200, 12 µ m 1800
Hans has flexible Diamond tools available in metal bondedelectroplated nickel and resin bond versions.
Hans has electroplated nickel and resin bond, and two kinds of Diamond flexible grinding and polishing tools.
Nickel Bond

The electroplated nickel layer with special electroplating process is used to wrap Diamond, which is mainly used for applications with coarse and medium particle sizes and requiring high material removal rate. First, metallize the fabric surface. The pattern is electroformed by nickel plating. By scattering Diamond on its surface, and then conducting electroplating treatment according to the specifications required by customers, the corresponding finished products are produced
Resin bond

Resin products are mainly used for fine grinding and polishing. Because of the continuous resin layer, the Diamond is embedded in the resin layer, so the product must be used after destroying the surface resin layer in advance to obtain the best performance.

Sintered bonded diamond is a type of composite material where Diamond particles are bonded together using a sintering process. Diamonds are incredibly hard and have exceptional wear resistance, making them valuable in various industrial applications, including cutting, grinding and polishing. Sintered bonded diamond tools and materials are used to take advantage of these properties.
Sintered bonded diamond materials are renowned for their extreme hardness and abrasive properties, making them ideal for cutting, grinding and polishingapplications in industries like construction, mining, metalworking, and stone fabrication. These tools are capable of cutting through hard materials like concrete, metal, and ceramics with precision and durability.
The specific properties of Sintered bonded diamond materials can vary depending on the Diamond particle size, the type of metal binder used, and the sintering conditions, allowing for customization to suit different applications.
The backing of diamond flexible grinding and polishing tools is a special fabric made according to special needs. Compared with our competitors, this unique process provides control and flexibility. This fabric has good dimensional stability, high wear resistance and excellent heat dissipation. This unique sheet can be combined with many different types of backing according to the application needs. Various backings (from fast grindingto flexible polishing are designed for optimal Diamond holding force, excellent workpiece edge wear, and can be combined with many different patterns and grain sizes to adapt to complex and diverse applications under harsh conditions.
Big dots: rough polishing for rapid surface removal. Particle size: 250um and 300um.
Medium dot: about 17 particles per inch, used for strong cutting, to improve surface grinding removal rate by improving coolant flow
Small dots: about 25 particles per inch, applied to special coating finish. Provides the fastest surface removal on very hard materials such as thermal spraying and ceramics.
Sturdy arrow pattern, specially developed for rapid material removal and finishing. It is very suitable for grinding when the belt is loose and for grinding surfaces with sharp edges. This structure has a working face in all directions, always in contact with the workpiece, to ensure that high level, fast and flexible grinding can be achieved without welding. The structure of the pattern also ensures good heat dissipation performance.
Nickel metal bonding agent - connecting arrow - closed type - medium fine particle - mainly used for discs.
Nickel bond - open line pattern - no connecting arrow - with higher flexibility and deburring ability - used for high-performance abrasive belt grinding and glass edging.
Flexible Diamond belt glass edging solutionSolution of glass edge grinding with flexible Diamond tape
It is specially developed in cooperation with the original equipment manufacturer and is designed to be equipped with an automatic glass abrasive beltpolishing machine.
The unique electroplating technology makes the Diamond electroplating layer firm and durable, avoiding scratches caused by the loose sand grain design of the standard traditional electroplating abrasive belt, and making the service life longer.
Selection of Diamond particle size
The most commonly used granularity is 120GGrit and 200Grit
Coarse grain size 60 or fine grain size 320 is occasionally required for special roughing or finishing.
Edge and corner treatment:
The 200 mesh shall be used for polishing the edge of 3-5 mm thick glass plate to achieve an edge angle of 0.5 mm.
120 mesh shall be used for polishing edges and corners of 6-10 mm thick or thicker glass plates to achieve 1.0 mm or larger edges and corners.
Use of wet grinding and dry grinding:
The automatic production line always uses coolant to improve the performance of Diamond tape and maximize its service life. Unless otherwise specified, use Diamond tape for grinding and polishing under wet grinding conditions.
Recommended working speed: 25 – 32m/s, maximum speed: 45m/s. The conventional belt runs at a speed of about 12-15m/s, and the Diamond abrasive belt grinds and polishes at a speed of about 25-32m/s and performs best. To provide the highest productivity, please run at a speed of about 25-32m/s
Technical Tips
The following precautions are recommended for optimum performance and service life. The parameter settings comply with the machine instructions and operating conditions:
Coolant: Use solvent free clean water and additives. Keep the flow constant at the grinding and polishing point.
Pressure condition: Apply correct pressure to the belt setting. Too low pressure will lead to varnish, and too high pressure will lead to uneven wear on the surface of Diamond abrasive belt. The tensile deformation of the sand belt is about 20mm.
Timing: Once the panel is transferred to the middle of the conveyor belt , the grinding surface of the abrasive belt should contact the glass. Align the center of the grinding surface to obtain the minimum contact point and the longest service life of the abrasive belt, and reduce unnecessary wear.
Belt guide pulley: clean belt guide pulley with flat surface shall be used to ensure smooth operation of the belt.
Configuration instructions - normal belt crown - or slightly inclined outer edge.
Equipment maintenance: regularly check the setting parameters of belt grinder to avoid unnecessary abrasion of abrasive belt caused by inaccurate parameter setting.
