most general arrangement for hollow spindle engine lathes is with a front and rear chuck. The rear chuck is bolted on the behind of the headstock to a special flange built into the machine specifically for this purpose commonly an A type mount. Using both chucks achieves a two point [link widoczny dla zalogowanych], extremely rigid and exact direction of holding a long part since both chucks are nailed to the spindle and are as close to die nuts as can be achieve with that lathe the part sprint out is basically the same as the spindle flee out you can not do better than that. Having two 4 jaw chucks too allows the part to be held off center in the spindle so boring alternatively machining an off-center hole can be achieved which would be very difficult with an ordinary engine lathe. 4 jaw chucks are very renowned with hollow spindle lathes for another reason they allow a flexibility in set up when a part is out of circular alternatively irregularly shaped that 3 jaw chucks can not mate.
The most constantly thought of use for a massive hollow spindle engine lathe is in the oil patch. Drill pipe is held in the spindle with two chucks so the special API (American Petroleum Institute) both interior and external tapered threads used to join rotary drill stem elements tin be machined. These very uncommon threads allow miles of drill pipe to be chained rapidly with a unattached turn and chained so well that they seldom crash in the floor. Because of the coarse management these threads receive (watch Discovery Channel shows on fuel drilling platforms) they can be marred and require repairs, which is why you forever see hollow spindle lathes contiguous anyplace where a lot of drilling is ashore. The drill pipe is upset forged on both ends where the machining needs to take place. One end of the pipe is a man tapered API thread and the other end is a petticoat API thread. Cutting this forged steel in a normal lathe using a steady recess would be a slow and complicated mission, merely with a hollow spindle lathe the work place is so close to the chuck and headstock and the part is held so well, highest cutting forces can be attained resulting it better quality and higher productivity than could ever be attained in a regular engine lathe.
Another location where hollow spindle lathes are necessitated namely the aircraft industry. There are a digit of parts in an plane that absence apt be swallowed and held with two chucks in the spindle of a big pierce lathe. The 2 parts namely come to idea are the landing gear piston gathering that doings for the shock absorber while planes touch down and the centre gist parts of spurt engines these parts are long and have a lot of ID machining that needs to be done approximate either ends ideal for a hollow spindle lathe.
In fix work, a hollow spindle lathe can retention a lot of disassembly and reassembly when a part has a lessen section then a bigger diameter partition consider of a pipe with a flange on the end. These parts can be machined on both ends using a large spindle cavity lathe without the need to clear the flange and reattach it this could save hours and hours of fatigue.
In production work [link widoczny dla zalogowanych], CNC hollow spindle lathes have largely taken over from manual lathes for the majority of this work. A lot of these lathes are designed for a particular household of parts for instance, drill pipe [link widoczny dla zalogowanych], or aircraft strut manufacturing. These lathes are built around a hollow spindle headstock with front and rear chucks then are customized for the household of parts they will be making. Often, tailstocks and long beds are distributed with in favor of a shorter, more contract design using fewer floor space for those shorter aircraft and hydraulic parts. A lot of the oil patch parts are absolute for hollow spindle holding these are parts designed to splice to the drill string and go down drill holes. There is a heavy emphasis on ID and OD threading on the ends of these parts that is an ideal applying for hollow spindle CNC lathes.
Some of the newer smooth bed big hole engine lathes are creature built with CNC controls as a higher productivity adoption to replace the older hollow spindle engin
