A wheel grinding device consists of a lower lifting rotary system, spoke grinding units, a center hole grinding system and an upper lifting and clamping rotary system. The wheel grinding device not only can be used for grinding the center hole of a wheel of any size via brush units of the center hole grinding system, but also can be used for grinding the back of wheel spokes of different sizes and shapes via the actions of brush belts of the spoke grinding units.

A tire pre-conditioning system includes a first mandrel, a second mandrel spaced apart from the first mandrel, and a controller in communication with the first mandrel and the second mandrel. The first mandrel is fixedly attached to a first shaft and including a first tapered sidewall. The second mandrel is fixedly attached to a second shaft and including a second tapered sidewall. The controller is operable to axially move the first mandrel and the second mandrel toward one another until the first and second tapered sidewalls are opposing respective beads of a tire, and supply pressurized fluid into an internal cavity of the tire to inflate the tire. The inflating causing the beads to move relative to mandrels while contacting the opposing respective tapered sidewalls to burnish the beads of the tire.

The disclosure discloses a double-station wheel deburring device consisting of two major systems. One is a wheel double-station exchange system responsible for feeding and discharging of two wheels, switching between a first working table and a second working table, switching between an upper station and a lower station, and rotation of the wheels. The other is a cutter feeding system responsible for feeding of a rim deburring blade, a riser deburring blade and brushes. The device can simultaneously remove burrs on outer rims, risers and valve holes of two wheels. Through the interactive double-station working tables, the feeding and discharging operation and the deburring operation are simultaneously carried out at separate stations. The device can be applied to deburring of wheels of different specifications. The disclosure also discloses a double-station wheel deburring method.

A grinding tool for machining an inside surface of a cylinder bore in a workpiece, the grinding tool having an axis of rotation, a grinding region which is cylindrical with respect to the axis of rotation and a conical grinding region axially adjoining the cylindrical grinding region. A diameter of the conical grinding region increases starting from the cylindrical grinding region in an axial direction with respect to a diameter of the cylindrical grinding region.
