Research of Operating Mode and Geometric Parameters of Combination Unit Cutter in Initiating Slotting

  • P. V. SazhinEmail author
New Methods and Instruments in Mining


The structure diagram and operation of a combination unit for drilling and initiating slotting are presented. The loads on the cuttier during initiating slotting are calculated, and the rational operating mode of the hybrid unit is determined.
