Precautions For Using Keyway Broaches

  1. Choose the right equipment:
    • The keyway broach needs to be used on a special broaching machine to ensure that the performance and accuracy of the broaching machine can meet the working requirements of the broaching tool.
    • Check whether the guide rails, transmission system and other components of the broaching machine are normal to ensure the smoothness and accuracy of the broaching process.
  2. To install the broach correctly:
    • When installing the broach, make sure that the center of the broach coincides with the center line of the broaching machine to avoid deflection during the broaching process.
    • Make sure the broach is securely clamped to prevent it from loosening or falling off during the broaching process.
  3. Choose appropriate cutting parameters:
    • Select the appropriate cutting speed, feed rate and cutting depth based on factors such as workpiece material, keyway size and accuracy requirements.
    • Avoid cutting parameters that are too large, which may cause overload damage to the broach; and do not choose cutting parameters that are too small, which may affect processing efficiency.
  4. Pay attention to the clamping and positioning of the workpiece:
    • The workpiece must be properly clamped and positioned before broaching to ensure that the workpiece does not move or deform during the broaching process.
    • The clamping force should be moderate. Excessive clamping force may cause the workpiece to deform, while too small a clamping force cannot ensure the stability of the workpiece.
  5. Observations and adjustments during broaching:
    • During the broaching process, the cutting conditions of the broach should be closely observed, such as cutting force, cutting temperature, surface quality, etc.
    • If abnormal conditions are found, such as excessive wear of the broach, excessive cutting force, decreased surface quality, etc., the cutting parameters should be adjusted in time or the status of the broach and equipment should be checked.

Application Fields Of Keyway Broaching

Keyway broaching has the characteristics of high precision and high efficiency. Its application fields mainly include the following aspects:

Automotive Industry

In the manufacturing of key components such as automobile engines and transmissions, keyway broaching is widely used to process keyways on various shaft parts.
