Cylindrical polishing machine is also called centerless polishing machine, centerless cylindrical polishing machine, round tube polishing machine, slender shaft polishing machine. It is mainly used for rust removal and polishing in hardware manufacturing, vehicle accessories, steel and wood furniture, instrument machinery, standard parts, and before and after electroplating. It is the best choice for polishing round pipes, round rods and slender shafts.

(1) Automatic feeding, centered cylindrical polishing When the polishing rotates at the speed n1, the workpiece will have a tendency to rotate at the same linear speed as the polishing . Due to the constraint of the friction force of the guide on the workpiece at the same time, the workpiece will be It rotates at a linear speed close to the guide (the linear speed of the guide is much lower than that of the polishing ), thereby forming a large speed difference between the polishing and the workpiece, thereby producing a grinding effect. Changing the angle of the guide and adjusting the frequency converter can also adjust the axial travel speed of the workpiece. During installation, the advancing direction and speed of the workpiece can be changed by adjusting the angle α between the axis of the guide and the horizontal plane.
Taking the workpiece as the research object, the force analysis is carried out. When the angle between the axis of the guide and the horizontal plane is adjusted to α, the radial direction of the guide and the radial direction of the polishing are also α. It can be seen that when the speed of the guide is constant When the angle α between the axis of the guide and the horizontal plane increases from zero, the value of sinα increases continuously, and the speed of the workpiece moving horizontally with the support frame also increases. When working, the center of the workpiece must be higher than the center line between the guide and the polishing , so that the contact point between the workpiece and the polishing and the guide is not on the same diameter of the workpiece, so that some convex surfaces on the workpiece rotate multiple times. It can be rounded successively in the middle to avoid grinding round workpieces.
Practice has proved that the higher the workpiece center is, the easier it is to obtain a higher roundness and the faster the rounding process, but the distance from the workpiece center should not be too large, otherwise the upward vertical component force of the guide on the workpiece may cause the workpiece to jump , thereby affecting the quality of the machined surface.
(2) Use high-quality corundum rubber s as guide s.
Generally, the grinding is composed of abrasives and adhesives. The abrasives generally include silicon carbide, corundum, diamond, cubic boron nitride, etc. Adhesives include resins, ceramics, brass, and the like. The advantage of using a harder corundum rubber as a guide is the wear resistance, increase the friction force, and avoid the loss of rotation.
(3) The workpiece clamping is simple and easy
When the workpiece is clamped, it is only necessary to put the shaft supports at both ends of the shaft into the bearing holes of the slider, without adjustment and alignment.
