The cylindrical grinder is a component on both ends of the headstock and tailstock to fix the center of the product, and then the grinding wheel feeds to grind the outer circle of the surface. The centerless external grinding machine does not need to locate the product center, and directly places the product on the bracket, and the wide grinding wheel performs clip-type grinding of the external circle of the product. The grinding machine refers to a machine tool for grinding the outer circle and outer surface of a workpiece.
Cylindrical grinding machines can be divided into the following types:
Cylindrical grinder: The grinding wheel frame is equipped with internal grinding accessories. The grinding wheel frame and head frame can be adjusted to an angle around the vertical axis. In addition to the dial rotation on the head frame, the spindle can also rotate. This kind of grinder can expand the processing range, grind the inner hole and the inner and outer cones with larger taper, and is suitable for small and medium batches and single-piece production. When external grinding is performed in the grinder, there are the following kinds of movements: The longitudinal reciprocating movement of the workpiece with the worktable is the longitudinal feed movement of the grinding outer circle. The high-speed rotating movement of the grinding wheel is the main movement for grinding the outer circle. The workpiece is rotated by the headstock spindle to grind the outer circle in a circular feed motion, and the grinding wheel makes periodic lateral feed motion.
plunge-cut cylindrical grinder: When the length of the workpiece is less than the width of the grinding wheel, the grinding wheel only needs to make continuous lateral feed, without relative axial movement with the workpiece. This kind of grinding machine has higher productivity.
Cylindrical end surface grinder: The wheel carriage is inclined at an angle around the vertical axis, and the surface of the grinding wheel is trimmed into two grinding surfaces parallel and perpendicular to the axis of the workpiece. It can simultaneously grind the outer circle and the shoulder end surface of the workpiece. Mass production.
