      hello all, i am new to this forum and need help for my project. i have to couple two shafts with a threaded connection i.e. there is a shaft of a dynamometer having internal threads and i have to fabricate a threaded shaft to couple these two shafts. the problem i am facing is that its giving misalignment issues. there is a misalignment of 0.2mm but for our work the misalignment should not exceed 0.05 mm. i have fabricated this shaft on simple lathe machine, i need your suggestion that how a precise shaft can be made without misalignment and which material should be used?
      moreover fabrication on CNC can solve this issue?
      looking forward for a quick response
      Regards

      hello,ehtisham,we come into have made similar shaft with hard chromed 1045 steel,you'd better make it on a CNC turning machine,which can ensure alignment and tolerance,it can reach +/-0.005mm accuracy.Our company equipped the doosan CNC turning machine,the maximum capacity for dia can be 350mm,if you have other question,please contact me by info@wharboprecision.com.
