Specifications

1.Depressed center
2.Aluminum oxide
3.Three reinforced net,strength,safe
4.High polishing ratio
5.Grinding all steel,metal

High hardness abrasive:ensure grinding sharp sex

High quality adhesive resin:ensure good durable performance

There are two kind of resin bond:powder phenolic resin and liquid phenolic resin.

Powder phenolic resin:Good technological efficiency,a smaller forming density,greater abrasives structure.

Liquid phenolic resin:Material is easy to agglomerate,It easy to make mixed material nonuniform and cause abrasive partially hard.

High quality reinforced net:ensure the product use security

Grinding Disc Product:

1.Size:125x6.0x22.2mm 5x1/4x7/8 inch

2.Shape:depressed center

3.Colour:black

4.Technical Specification:A30#RBF two or three reinforced fiberglass nets

1)A30#:Aluminum oxide material grit size 30#

2)R:Hardness grade,Generally,please chose reasonable hardness.These factors can affect the hardness:The amount of resin bond to join,Forming density of abrasive,Sintering temperature and sintering temperature etc.

3)BF:Bonding agent is resin and Fiberglass reinforced

5.Speed r.p.m:12200

6.Speed m/s:80m/s

Grinding Disc Feature:

1.AO for long life and high material removal,

2.Shape allow greater surface grinding coverage,

3.Three sheets of fiberglass ans two paper sheets for durability and safety,

4.Bear high shocking and bending,

5.Avoid damege caused by vibration of wheel on processing surface,

6.High strength,sharpness and low consumption make grinding efficient,economical and safe

Grinding Disc Application:

1)the industry maybe use this wheel

1.foundaries

2.Shipbuilding,

3.machine builders,

4.Metallurgy,

5.manufacturing of power vessels,

ing,construction.

2)application:

grinding wheel is used for grinding metal,like cast iron,steel pipe,alloy steel, quench steel, tool steel ,steel bar, the burr and gross edge of steel plate, steel welds, etc.

Domestic leading molding equipment:ensure the stability of the product performance

1.Check the disc's appearance:

2.Check disc"s diameter

3.Check disc"s thickness

4.Check disc"s inner aperture

Safety Recommendations:

1.Wear protective goggles
2.Wear protective gloves
3.Wear ear protectors
4.Wear dust respirators
5.Observe safety recommendations

Test quality:

1.Check disc:Before installing the disc,please check the disc carefully, to see if it is cracked and damage.Make sure the disc emit clear voice with wooden hammer or rubber hammer.

2.Check machine:Before installing the disc,also please check machine's rotate speed,using the disc in the range of specified maximum speed.

3.Please install the disc smoothly, medium tightness.After installation, please make the disc idle about 1minute before grinding workpiece.

4.Make sure workpiece is stable.Hold the tool so that the disc is at a perpendicular angle to the workpiece,

5.Keep a light touch, as the disc will break under too much pressure.

Main grinding phenomenon after attrition:

1.Self-excited vibration and workpiece surface appear regenerative ripplingin grinding process.

2.Grinding noise increase,

3.The workpiece surface appear grinding burn,

4.Grinding capacity increase or decrease rapidly,

5.Grinding accuracy go down,

6.Grinding surface roughness increases.

These phenomena are not independent, all kinds of phenomena caused by correlation. Among them particularly pay attention to the workpiece surface"s thermal damage due to grinding temperature is too high.Also pay attention to the roughness and the accuracy decline due to self-excited vibration.

Grinding Disc Packing:

1.During transport,please load and unload carufully to prevent the crack and shock.Ensure packing without damage.

2.During storage,put the wheels horizontally,donot touch the floor directly.

3.Should prevent moisture and direct sunlight,keep the warehouse shady and ventilated.The warehouse's temperature can not be less than 5 degrees
