1. The outer part of the outer ring is disassembled and dismantled; the outer ring is screwed on the outer circumference of the outer casing; the screw is evenly tightened on one side. Take it apart. These screw holes are usually covered with blind plugs; vibrating screen tapered roller bearings and other separate bearings; several cuts are placed on the outer casing shoulder; use the block; use a press to disassemble; or slam the open.
2, the opening of the inner ring of the vibrating screen cylindrical hole NTN bearing; can be pulled out by the pressure machine. At this moment; pay attention to let the inner ring accept its pulling force.
The inner ring of the large-sized vibrating screen bearing is disassembled by the oil pressure method. It is hydraulically pressed through the oil hole provided on the shaft to make it easy to pull. The NTN bearing with large width is used in combination with the hydraulic drawing method; Open the homework.
NU type, NJ type cylindrical roller vibrating screen bearing inner ring can be opened by induction heating method. Jia Yilong reminds you: heating part in a short time; making the inner ring swell and then pull it.
3. The taper hole NTN bearing is disassembled and disassembled to be smaller than the fixed sleeve NTN bearing; the inner ring is supported by the block fastened on the shaft; the nut is turned back several times; the block is hit with the hammer open.

Vitrified Grinding Wheels

Vitrified Grinding Wheels mean grinding wheels in ceramic bonded. Vitrified grinding wheels can be superabrasive grinding wheels like diamond grinding wheel or CBN Grinding Wheels. It also can be abrasive grinding wheels such as white aluminum oxide grinding wheel,pink grinding wheel,silicon carbide grinding.

Vitrified grinding wheel is only one type of bond, which is ceramic, it can be in any type of abrasive.

The main ingredient of vitrified bond are vitreous material with low melting point, such as borosilicate glass, lead glass, etc.It is widely used in various grinding methods such as outer circle, inner circle, flat surface, centerless, etc. It is the most commonly used bonding agent for abrasive tools.

Vitrified bond is characterized by high chemical stability, almost can work in a variety of cooling media, small elastic deformation, brittle, can be made into a variety of hardness levels of grinding tools to adapt to the processing of various hardness of the workpiece. Vitrified bond has good self-sharpening.

The grinding efficiency of single crystal diamond with vitrified bond grinding wheel is higher than metal bond grinding wheel. The wear ratio is very small and the processing cost is low. Therefore, the grinding efficiency of single crystal diamond with ceramic bond grinding wheel can be greatly improved.
