Product Description
Seamless steel tubes with ST52 /20#/25Mn/27SiMn honing hydraulic cylinder tubes for machinery
Production description
Honing is a grinding or abrading process ,In it , a very little materials is removed ;
This process is used primarily to remove the grinding or tool marks left on the surface by previous operations ;
The cutting action is abtained from abrasive sticks (aluminum oxide or silicon carbide) mounted in a mandrel or fixture ; A floating action between the work and the tool prevails so that any pressure exerted on the tool is exerted and transmitted equally on all side ;
Coolants are essential to the operation of this process to flush away small chips and keep temperature uniform ;
