Comparison between the xueji S series and the Original Boring Tool Scheme

  • The quality of hole wall processed by reamer is much higher than that of milling cutter
  • Reamer does not need to be processed twice, and milling cutter needs to mill twice after 500 holes to ensure the quality of hole wall
  • Hole milling cutter cannot process holes above H60mm, but reamer can. For holes below H60mm, reamer has obvious efficiency advantage
  • The comparison of reamer and milling cutter life is as follows:

 

Heat exchange plate thickness

Combining relevant data and comparing under the premise of meeting precision requirements, the processing efficiency, life and finish of reamer are significantly improved, and it brings high-value hidden advantages, which meets the improvement requirements, meets the core needs of enterprises for long-term stable processing, increasing quality stability, reducing comprehensive costs, and improving comprehensive competitiveness in the industry.
