Hau ol i save mekim wok bilong 'Honing' (Step-long-Step)
1. Wok bilong redim samting
Ensin blok i stap antap long masin bilong 'honing'.
Ol hul bilong silinda i stap stret wantaim'spindle axis'.
A tul bilong 'honing' (mandrel)i gatol ston we i save brukimnasu bilong stiaimol i makim bihainim sais bilong hul na ol samting bilong wokim (planti taim ol i save makim ain o aluminium aloi wantaim ol lain).
2. Honing Operesen
(a) Tul Engejmen

Ol i save was gut long dispela wok bilongsais bilong hul, jiometri, na pinis bilong pes.
Ol i save putim 'coolant' (planti taim em i wanpela 'honing oil' o 'emulsion') long:

Mekim wokpis i kol
Putim gris long 'abrasive action'
3. Otomatik In-Proses Mesamen
Ol masin bilong nau we CNC o servo- i save yusim:
Ol masin bilong skelim win o LVDTlong skelim 'bore diameter' long taim tru
