  • What problems may occur with the reamer?
    The twisted holes are machined to achieve precise dimensions and shapes. High-speed steel reamer is used for the reaming workpiece has been drilled (or widened hole) after the machining hole, mainly to improve the accuracy of the hole processing, reduce the roughness of its surface, is used for the
  • What are the precautions for using the reamer?
    Reamer is generally divided into hand reamer and machine reamer two kinds, hand reamer handle for the straight handle, the working part is longer, the guiding effect is better. Consisting of the working part, neck, and handle. The working part is divided into the cutting part and the calibration par
  • How to use the reamer safely?
    Reamer is used for reaming workpieces that have been drilled (or widened holes) after the machining hole, mainly to improve the accuracy of the hole, reduce the roughness of its surface, is used for the finishing of the hole and semi-finishing tools, machining margin is generally very small. Here's
