    Grind-hardening is a hybrid process that combines material removal and surface hardening of a steel workpiece at the same time. The heat dissipated in the cutting area is used for the heat treatment of the workpiece (Salonitis 2015a).For the grind-hardening of a workpiece, the generated heat in the interface between the grinding wheel and the workpiece material and the subsequent cooling of

    Before grinding the edge of the chisel check the chisel head has not 'mushroomed'; if necessary, grind the head to remove any burr which could fly off when the chisel is hammered. To sharpen the edge, hold the chisel, upwards in line with the wheel and, supporting your hand against the tool rest, tilt the chisel forward until it strikes the face of the wheel at the correct angle.

  • 2. GRINDING, HARDENING & ANNEALING |

    After coarse grinding, the edge is hardened by heating it to 820°C and then rapidly cooling it in cold water. The hardening makes the steel much harder, but also rather brittle. To remove the stresses in the steel caused by the forging and hardening, the steel needs to be annealed, which involves keeping the axe heads in an oven at 195°C for 60 minutes.

  • Which Grinding Wheel Should I Choose? | Norton

    A grinding wheel is a precision tool with thousands of cutting points on its surface - abrasive grains that are held in place by a bond matrix (hence these are known as bonded abrasives) and separated by pores.. These pores are hollow spaces between abrasive grains and the bond, which help with the clearance of discarded metal chips in the grinding process.
