4、 Product Introduction and Technical Parameters

1. 1A1Flat grinding wheel

Basic applications: cylindrical grinding, flat grinding, tool cutting

Size range: outer diameter50–500 mm, thickness4–40 mm(Typical value, can be customized according to needs)

Adhesive: resin（K）Metal（BZ）Optional

Working principle: When the grinding wheel rotates at high speed, the diamond orCBNParticles perform micro cutting on the surface of the workpiece, gradually removing the material. By selecting different particle sizes and concentrations, the material removal rate and processing surface quality can be controlled.

2. 6A2Bowl shaped grinding wheel

Basic use: End face grinding, rear corner grinding of milling cutters and drill bits

Size range: outer diameter75–350 mm, thickness3–100 mm

Bonding agent: mainly metal bonding agent, resin can also be selected

Working principle: Grinding is carried out by contacting the workpiece with the end face (bowl shaped top plane) or edge slope of the grinding wheel, commonly used for complex angle forming of tool grinders.

3. 11V9Cup shaped grinding wheel with blade edge

Basic use: profile grinding and slotting of hard alloy cutting tools

Size range: outer diameter50–150 mmThe granularity is usuallyD126orD91

Adhesive: resin adhesive

Working principle: The outer side of the grinding wheel is equipped with a narrow abrasive ring (i.eUsing only this narrow ring to contact the workpiece during grinding can reduce grinding resistance and is suitable for processing fine grooves and complex contours.

4. 12A2/45Angle grinding wheel

Basic use: Has45A grinding wheel with an inclination angle of °, suitable for forming machining of gears and threads

Size range: outer diameter75–150 mm, oblique angle45°

Bonding agent: metal or electroplating bonding agent

Working principle: The inclined surface on the circumference of the grinding wheel is in contact with the inclined teeth or threaded surface on the workpiece, and the required angle is ground in one forming process. Electroplating binders can make abrasive particles protrude higher and have stronger cutting force.

5. 14A1Cylindrical grinding wheel

Basic use: Internal grinding, inner hole machining of sleeve parts

Size range: outer diameter50–400 mmThe wall thickness is set according to the aperture

Bonding agent: Metal bonding agent

Working principle: Grinding the surface of the inner hole of the workpiece with an external grinding wheel, used in conjunction with an internal grinding machine. Metal binders help maintain the shape stability of grinding wheels.

6. 1A1WGrinding needle

Basic use: Manual or machine grinding of small holes, narrow slots, and mold cavities

Size range: Head diameter4–20 mm, stem diameter3–6 mm

Bonding agent: Electroplating bonding agent

Working principle: Diamond particles are fixed on the head of the steel needle body by electroplating, and the protruding height of the abrasive particles is large, suitable for local deburring or shaping in small spaces.

5、 Advantages and Characteristics

Three types of binders to choose from

STROHProvide three bonding methods: resin, metal, and electroplating. The grinding temperature of resin bonding agent is low, the shape retention of metal bonding agent is good, and the protrusion of electroplated bonding agent abrasive particles is high. Users can choose the most suitable bonding agent based on the workpiece material and grinding machine conditions.

The coverage range of particle size and concentration is relatively wide

Granularity fromD180(coarser) toD15(Finer) varies, with concentrations ranging from25to150There are a total of eight levels. Coarse grinding uses high concentration large particle size, while fine grinding or polishing uses low concentration fine particle size. The same grinding wheel can complete the transition from rough machining to semi precision machining.

Shape system andSERMACorresponding to the height of the grinding wheel

In the directory1A1The6A2The11V9All shapes are internationally recognized codes, andSERMAThe shape naming of the product is consistent, making it easy for users to directly select and replace without the need to modify grinding machine fixtures or adjust processing parameters.

Clear adaptability of materials

Diamond grinding wheels are suitable for hard alloys, ceramics, glass, and stone materials;CBNGrinding wheels are suitable for high-speed steel and tool steel. Clear division of labor reduces the cost of trial and error.

We can provide customized contour grinding wheels

For non-standard shaped workpieces (such as tools or molds with complex surfaces),STROHIt is possible to produce shaped grinding wheels according to the drawings, reducing the need for multiple trimming processes.

6、 Main application areas

Manufacturing of Hard Alloy Cutting Tools

For example, rough and fine grinding of milling cutters, drill bits, and reamers. useSTROH 1A1or11V9Diamond grinding wheel, matched with appropriate particle size（D126–D64）And concentration（75–100）It can achieve stable material removal.

Ceramic and glass processing

Used for cutting and grinding industrial ceramic parts, optical glass, and quartz pipes. Recommend using metal bond grinding wheels (such as6A2）, granularityD151–D91More suitable.

Mold manufacturing and repair

Grinding and polishing of the cavity of injection molds and stamping molds. available1A1WPolish the needle for local adjustment, and then use diamond grinding paste（D15–D7）Complete surface treatment.

Gear and bearing industry

Grinding of carburizing steel and bearing steel. Due to the workpiece being made of black metal, it is recommended to useCBNGrinding wheel (such as12A2/45The angle grinding wheel is used, and a metal bonding agent is selected as the bonding agent to achieve better shape retention.

Precision machining of mechanical components

Including hydraulic valve core, piston rod, sealing ring, etc. use1A1Flat grinding wheel, particle sizeD91–D64, concentration50–75It can achieve lower surface roughness values.
