Step 1: Initialization and clamping. Boot the machine and initialize, install the honing head and rough honing oilstone, fix hydraulic cylinder on the fixture, adjust appropriately height, lock work piece fastening chain. Set up stroke stop point and technological parameters.
Step 2: Rough honing. Turn on the short stroke switch. At the beginning, the stroke speed and honing pressure should be little, and increase gradually after the smooth running. Watch the pressure gauge and manually amend the cylinder taper. According to the scratch depth, several times honing are needed. First rough honing allowance should be controlled within 0.05mm, and then check the surface by using the flashlight. If scratch still exists, rough honing again, machining allowance is controlled within 0.3mm.
Step 3: Fine honing. After rough honing is finished, put on the fine honing oilstone, reset technological parameters according to requirements. The working time should be controlled within 2-3 minutes and the bore diameter should be measured again.
Step 4: Polishing. Cover special polishing cloth around fine honing oilstone, polishing time should be controlled within 3~4 minutes. When removed honing head out of bore, oilstone should be adjusted appropriately to avoid oilstone or guide frame scratching cylinder bore.
Step 5: Detection and removal of work piece. After the removal of the honing head, measure inner diameter of the cylinder bore by micrometer and then write down a record. Finally work piece are removed and placed in the specified location.
