On lathe turning grows diameter comparing to be more than the aperture of 4, because the tigidity of arbor is poor, the vibration when cutting, affect cutting efficiency and the quality that machine the surface, brought difficulty to turning. Especially bore diameter is bigger and aperture is very deep, below the condition that contains step, as a result of the influence of tigidity of arbor, machine tool, treatment is more difficult. Machine quality and efficiency to improve work, the design made the tool that article place introduces, turning step deep aperture, the effect is very good.

Mix with chuck on lathe of preexistence of tool of aperture of car of attached drawing of square knife stage central wearing installs good work, with inside Kong Dao processes work the short aperture of two end, match to cover each with special arbor. When aperture grows among turning, load Zun Duan's splicing sleeve workpiece aperture first inside, get on workpiece installation in lathe again, jut knife head length has been adjusted on arbor, the splicing sleeve of along with left end loads the aperture inside workpiece together, the mat that use a knife adjusts good arbor on any account, secure arbor go up in stage of lathe square knife, make arbor is moved in the crafty that in covering, can freely, can make workpiece rotates, begin knife cutting, till workpiece till fore-and-aft deepness. After workpiece car is over, again retrorse shift procrastinates greatly board, the splicing sleeve of along with right end and arbor are exited from inside workpiece together, can debus workpiece. When machining the 2nd, install the splicing sleeve of good Zun Duan first, hold clip good work, extend arbor the person to arrive inside splicing sleeve of workpiece Zun Duan again, outfit is very right carry splicing sleeve, can begin the turning of the 2nd workpiece. Knife head extends the length H of arbor, press type calculates: In H=D-d (mm)2 type: D -- workpiece aperture (Mm) ; D -- arbor diameter (Mm) . The characteristic of tool: Two end use arbor of splicing sleeve bearing, increased the tigidity of arbor greatly, make cutting does not have vibration, assured to already machined exterior surface roughness; Two end use turning of arbor of splicing sleeve bearing, assured positional precision of Kong Jian; The operation is handy, efficiency raises 5 times above than traditional reaming method.
