Hydraulic Honing Machines

Electropneumatics’ range of honing machines meet the critical requirements of a wide variety of honing applications. They guarantee fast, accurate and precise honing of small to very large parts thereby offering higher productivity and efficiency to the user. They can be used to maintain diameter tolerance, correct taper, out-of-roundness, bell-mouth, waviness, misalignment in bores and for removing machining marks from bores. These honing machines are available in the following options:
  1. Light duty - for small parts such as two-wheeler engine master and brake cylinders, connecting rods, rocker arms and gears, valve and pump bodies
  2. Medium duty - for compressor blocks, multi-cylinder engine blocks and liners, extruder barrels, hydraulic and pneumatic cylinder barrels
  3. Heavy duty - for large, long parts such as heavy vehicle engine blocks, process industry tubes and liners, big hydraulic and pneumatic cylinder barrels
  4. Special - with multi-spindles and automation for high volume production
