Precision Honing  the engine machining processing of the following ways:
( A ) the surface of the cylinder bore
  Compressed gas cylinder bore is burning and swell space , and play the guiding role of the piston , the cylinder bore surface is
The most serious engine wear one of the surfaces , which determines the engine overhaul period and life.
Cylinder bore honing is the final finishing step , after honing textured surface with a cross , is conducive to Run
Oil storage and oil film retention , and has a high support rate , able to withstand greater loads , abrasion resistance,
Long service life.
 2 the crankshaft hole honing
The main crankshaft of the engine moving parts ,
The quality of the crankshaft hole processing engine performance
Will have a great impact , so the engine crankshaft hole is generally more stringent process requirements , including diameter ,
Set , roundness , the center of the file crankshaft hole straightness and surface roughness .
 Honing help reduce the residual stress in the surface of the crankshaft hole improve the surface quality . Honing is used mostly by cutting fluid filtered kerosene or kerosene plus spindle oil , may also have extreme pressure emulsion. Easy to cut erosion
Crumbs, to avoid clogging honing , while reducing the temperature of the cutting area and the surface roughness .
 ( 3 ) connecting rod bore ( large and small end ) honing
  Pistons and crankshaft connecting rod is in the middle part , the main role is to shift the piston reciprocating motion
A rotary motion of the crankshaft . Rod machining accuracy will directly influence on the engine performance ,
Which rod head size hole machining important process of connecting rod machining , precision machining on its link quality has a greater impact . After honing makes connecting rod hole tolerance level reaches IT6, surface roughness
Ra to be less than 0.4μm; small head hole tolerance grade IT8, surface roughness Ra should be less than 3.2μm. To meet the needs of the machining accuracy .
( 4 ) in the injector nozzle and piston honing the processing of a number of tiny holes , hole honing surface roughness can increase the difference between the nozzle flow coefficient of 0.8 or more; can eliminate the pressure chamber and the discharge hole glitches , expanding its line of intersection of the fillet , reducing high pressure oil pressure loss ; reducing orifice surface roughness , increasing the speed of the oil , get a good atomization ; nozzle flow coefficient can be increased , so that dynamic spray angle and flow tends to a to ,
Reduces fuel consumption and emissions targets.
