  • Patent number: 11684982
    Abstract: A key duplicating machine and duplicating process are disclosed. The key duplicating machine comprises a base, a main axis processing device, a detecting device, a feeding device, a clamping device and a drive device. The base comprises a vertical plate and a horizontal plate, separates the horizontal plate into a front part and a rear part. The main axis processing device and the detecting device are both flexibly connected to the vertical plate and arranged on the side facing the front part. The base separates the processing area from the drive area so that processing residues produced in the processing area will not easily invade the drive area, ensuring that the drive area will be clean and free from contamination, reducing the probability of damage to the motor, guide rail and other structures in the drive area, and increasing the stability and lifespan of the key duplicating machine.

  • Patent number: 11660684
    Abstract: An example method includes performing a machining operation by providing linear movement of a tool along a feed axis relative to a workpiece while superimposing oscillation of the tool onto the feed axis and providing rotation of the tool relative to the workpiece. During an optimization mode, the machining operation is performed on a first workpiece portion while providing the linear movement at an initial feed velocity, and sequentially superimposing the oscillating at a plurality of different frequencies. An optimal oscillation frequency is determined from the plurality of different frequencies which causes the tool to apply less force to the first workpiece portion at the initial feed velocity than others of the frequencies. During a run mode, the machining operation is performed on a second workpiece portion having a same composition as the first workpiece portion while superimposing the oscillation at the optimal oscillation frequency.

  • Patent number: 11654521
    Abstract: A tool machine magazine includes a base, a tool disc disposed on the base, tool sleeves disposed on a periphery of the tool disc through a bearing, a motor, a brake structure, a cam, a driver shaft, an angle sensor, and a control terminal. The motor drives the cam to operate. Each bearing orderly operates along the outline of the cam, driving the tool disc to continuously rotate without intermittence. The angle sensor is disposed on one end of the driver shaft or a rotation center of the tool disc. When the rotation angle of the tool disc matches the tool change command, the control terminal controls the brake structure to stop the motor, so as to stop the tool disc for facilitating the tool change operation.
