Centerless Grinding is also called centerless grinding, which is a kind of grinding process. There are two grinding wheels for the guide wheel and the grinding wheel. The guide wheel drives the cylindrical workpiece to rotate on the shim, and the grinding wheel plays a grinding role on the workpiece. Unintentional grinding belongs to the Zhou Mo method.
The heart grinding method is composed of three mechanisms: a grinding wheel, an adjustment wheel and a workpiece support (bracket), in which the grinding wheel actually performs the grinding work, the adjustment wheel controls the rotation of the workpiece, and causes the workpiece to enter the cutting speed As for the workpiece support, which supports the workpiece during grinding, there are several ways to match these three parts, except for stopping grinding, which is the same in principle.

Valve
Valve principle of operation: When the air inlet below the valve body into the air intake valve above the body to stop the intake, the piston chamber reciprocating motion, then pull the piston rod back at this time in the sealed plastic state (dispensing preparation Former work), on the contrary, the plastic state. When the glue is supplied by the compressed air into the glue valve body, the glue is pressed into the glue tube connected with the piston cavity. When the piston is in the up stroke, the piston cavity is filled with glue. When the piston pushes down the glue dispensing needle When the glue from the needle point out. Point out the amount of glue volume, the distance from the piston under the red, the size of the pressure, the length of time to decide, the plastic valve itself can fine-tune the size of the glue.
