At this time, there will be slippage between the grinding wheel and the workpiece, which may produce vibration and noise, reducing grinding efficiency and surface roughness. At the same time, due to the increase of grinding force and grinding heat, the workpiece will be deformed, which will affect the grinding accuracy, and even cause grinding surface burns and small cracks in serious cases.
In addition, due to the uneven hardness of the grinding wheel, different working conditions of abrasive particles, uneven wear on the working surface of the grinding wheel and abrasive particles falling off at different parts, the external viscosity of the grinding wheel is lost, which affects the shape accuracy and surface roughness of the workpiece surface.
2. Grinding wheel dresser can be used for dressing. Grinding wheel dresser is a special machine tool accessory used for manual surface grinding, universal tool grinding, various surface grinders and curve grinders to dress various grinding wheel sections composed of straight lines and circular arcs.
Dressing methods include grinding wheel dressing, turning, using diamond rollers, grinding and rolling.
Extended data:
Grinding wheel dresser includes universal grinding wheel dresser, perspective grinding wheel dresser, universal perspective grinding wheel dresser, angle grinding wheel dresser and conventional grinding wheel dresser.
Precautions for use:
1. When in use, the grinding wheel dresser should be placed on the magnetic chuck of the machine tool (or fastened on the workbench) and positioned (or corrected) by one side of the base to adjust the center height of the grinding wheel of the machine tool to be different from that of the diamond cutter or the concave-convex arc.
2. In order to ensure the normal work of the dresser, the swinging, rotating and moving parts should be flexible and reliable during use. Therefore, it should be cleaned and oiled in time to prevent bumping and corrosion.
