Operation principle of main basis profile modelling turning of design plan of this dedicated device . Include the design of the bedside case and enter to the design of the organization. The bedside case wants satisfied 4 grades to change speed, and can apply the brake rapidly while changing the work piece . Enter to the organization including getting vertical, trough of slippery organizations of crank and type. The vertical , two horizontal directions of the lathe tool move and adopt the hydraulic pressure to urge , so the design systematic in hydraulic pressure influences the working performance of the lathe directly rationally. Among hydraulic pressure system, bed saddle slip sport direction of piece control by one's own 3 electromagnetic reversing valve of Stone separately, sport its speed install in each cylinder going back to transfer speed valve and 2 electromagnetic reversing valves 2 times jointly control oil passaging. Is it flow valve adjust systematic oil pressure , adjust number value after can be measured by the manometer to overflow. A fine dedicated device should reach : 1)Boost productivity and worker labor productivity, lighten worker work strong notably. 2)It is reliable that the work is steady, have long performance life. 3)Easy to maintain, with low costs. Verify according to theory above-mentioned schemes reach demanding basically. Keyword: copying lathe ； hydraulic pressure system ；PLC II
