  • Patent number: 6648727
    Abstract: A grinding machine has an abrasive wheel mounted on a spindle carried by a wheelhead which provides for movement in a direction perpendicular to the spindle. A pair of workheads are separately mounted on workslides and cross slides so that the workheads may be moved along an X-axis or a Y-axis as required to bring chucks of the workheads into grinding position. Sliding movement of the workslides and cross slides is produced by ball screws powered by servo motors and mounted on bearing housings, with the ball screws propelling ball nuts connected to the slides. The machine uses CNC computerized controls, with each of the workheads having a separate and independent control. This enables attainment of a high degree of precision.

  • Patent number: 4523499
    Abstract: A rotor disc brake lathe for simultaneously machining both left- and right-hand disc brake rotors of a vehicle wherein the rotors are mounted on opposite ends of a centrally supported horizontal drive shaft, and a pair of tool arm assemblies are mounted on both opposite end regions of a horizontal cross arm which is moved vertically on machine ways to effect selective engagement with and machining of the rotors. A spring biased vibration dampener is mounted on one of each pair of tool arms for engagement with one side of each rotor during the machining operation. A clutch mechanism to allow selective manual or motor driven vertical feed of the cross arm is provided.
