Mofuta le boholo ba lisebelisoa tsa ho bentša
Lisebelisoa tse sebelisoang haholo bakeng sa ho bentša fatše ka konkreite ke li-discs tsa ho sila tsa PCD, li-disk tse silang tsa tšepe le lipache tsa ho bentša bond ea resin.Li-discs tsa ho sila tsa PCD li sebelisetsoa ho tlosa liphahlo tse teteaneng fatše, li-disc tsa tšepe tsa bond li sebelisetsoa ho lokisa holim'a fatše le ho sila ka thata, li-resin bond polishing pads li sebelisetsoa ho sila le ho bentša.Nomoro ea grit ea lisebelisoa tsa ho bentša e bolela boholo ba likaroloana tsa daemane tse ka har'a lisebelisoa.Ha palo ea grit e le tlase, boholo ba karoloana ea daemane e kholoanyane.Ha ho na nomoro ea grit bakeng sa li-discs tsa ho sila tsa PCD, empa li na le tataiso, ho ea ka nako le ho pota-pota.Re hloka ho ela hloko tataiso ea eona ha re sebelisa PCD.Metal bond sila discs hangata tla le grits 30 #, 50 #, 100 #, 200 #, 400 #.Hangata re etsa qeto ea hore na ke grit efe e lokelang ho qala ho latela maemo a fatše.Ka mohlala, haeba boemo ba fatše bo se botle kapa bokaholimo bo batla bo hlephile, ho ka 'na ha hlokahala hore re qale ka li-discs tsa 30 # tsa tšepe tsa bond ho tlosa bokaholimo bo hlephileng le ho lekanya fatše.Haeba re batla ho pepesa aggregates, 50# kapa 100# tšepe bond grinding discs ho hlokahala.Lisebelisoa tsa ho bentša li-resin bond li tla le grits ho tloha ho 50 # ho isa ho 3000 #, li-grits tse fapaneng li khetholloa ka 'mala o fapaneng oa Velcro.Ho na le lipache tse teteaneng tsa ho bentša le tse tšesaane tsa ho bentša.Li-pads tse teteaneng tsa polishing li tiile li loketse boholo bo mahareng le li-grinders tse boima.Li-pads tse tšesaane tsa polishing lia tenyetseha tse loketseng lisila tsa boima bo bobebe bakeng sa ho bentša hantle.
