Choosing A Lathe
Bed Type Follows The Part
Sixty models is a lot to read through. Send the part instead: the largest diameter, the length, the material and the tolerance, and we will name the two or three that fit and say why.
-
Flat bed for weight
A wide flat bed carries heavy, long work and damps the cut. It is the right choice for shafts, rolls and anything needing a steady rest, and it is easier to load with a crane.
-
Slant bed for chips and speed
Chips fall into the conveyor instead of piling on the ways, and the turret sits closer to the spindle centreline. Best for repeat production of medium parts.
-
Vertical for diameter
Once the part is heavier than it is long, gravity works with you rather than against you. Flanges, rings, wheels and gearbox cases belong on a table, not between centres.
-
Y-axis when it saves a setup
A power turret and a C-axis pay for themselves the moment the part would otherwise move to a machining centre for a keyway, a flat or a cross hole.

CNC Pipe Threading Lathes Questions, Answered
What are CNC pipe threading lathes used for in the oilfield?
Cutting new threads and recutting damaged ones on drill pipe, couplings and casing. The large through-bores and twin power chucks hold tubulars that would never pass a normal lathe spindle, and between thread jobs the machines still work as general lathes — which is why service yards keep them busy year round.
Why do these lathes need twin chucks and oversized through-bores?
A tubular has to pass through the spindle and be gripped at both ends to run true — one chuck on a long pipe leaves the free end whipping. The twin-chuck arrangement centres the pipe through the bore, which is what lets the thread land concentric on a workpiece metres long.
Can damaged oilfield threads be recut instead of scrapping the pipe?
Yes — recutting is half the work these machines do. The damaged thread is cut away and a fresh thread run on the remaining length, which turns a scrap tubular back into a serviceable one for a fraction of replacement cost. The QK13 and QKD13 series are built around exactly this job.
Which threads and pipe sizes do the QK/QKD series cover?
The group covers the standard oilfield tubular range — drill pipe, casing and couplings — with the through-bore of each model setting its maximum pipe size. Tell us the pipe OD, the thread standard you run and whether couplings are fitted, and we will name which of the five machines covers it.
