NUMOBAMS NU6136 355*1000mm 1.5KW(2HP) with 160mm Chuck Industrial Manual Metal Lathe Machine

Product Overview

A floor-standing manual metal lathe for real workshop sizes

The NU6136 is an industrial metal lathe built for workshops that have to turn real hardware — a worn pump shaft, a replacement sleeve, a flange that needs facing and boring — without tying up a production machine. Everything is worked by hand: carriage, cross slide, compound and tailstock, each on its own handwheel or lever. Nothing has to be programmed, so the first cut on a new job happens minutes after the part reaches the chuck.

Shops that already run a cnc turning machine usually keep a manual lathe alongside it, because the jobs that cause the most delay are rarely the ones worth setting up a program for. A single replacement part, a thread that has to match an existing fitting, a weld build-up that needs re-machining: ten-minute jobs here, half a shift on a programmed machine.

It suits repair and maintenance departments, small job shops and prototype benches, and it is comfortable in steel, aluminium, brass and bronze. Parts up to roughly the size of a gearbox shaft sit between centres, and bar stock passes straight through the spindle bore for repetition turning.

Where it sits in the range matters as much as what it does. It is not a benchtop machine that has to be lifted onto a bench, and it is not a production lathe with a control. It is heavy enough to take a serious cut in steel, conventional enough that a competent machinist is productive on the first day, and simple enough that nothing critical depends on software.

Set against a cnc machine lathe of similar capacity, the difference is not accuracy; it is overhead. Feed and speed are chosen by hand, the cut is felt through the handwheel, and there is no post-processor or tool-offset screen standing between the operator and the first chip.

Build & Rigidity

• A bed casting that soaks up vibration — the bed is a single heavy casting with machined guide ways, which is what keeps a finishing pass clean when the tool is working out near the chuck.
• Apron controls where the hand expects them — feed engagement, feed direction and the half-nut lever all sit on the apron, so switching between turning and threading needs no reach across the machine.
• Camlock spindle nose — the chuck mounts on a quick-release camlock nose and comes off in seconds when the job needs different workholding.
• Tailstock built for drilling — lever clamping, a graduated barrel with 95 mm of travel and a locking clamp for centre work, drilling and reaming.
• Coolant and light at the cut — a coolant pump and hose deliver flood coolant straight to the tool, and a work lamp lights the cut for close work and for reading the dials.
• Handwheels, not a screen — on a lathe cnc machine the axis positions come from a controller and a display; here the graduated dials give direct feedback, which is how an operator feels chatter building before it reaches the surface finish.
• A frame that keeps its rigidity — the bed is wide and deep for an industrial metal lathe of this size, and buyers who step down from a cnc machine lathe usually notice how much of that stability is still here.
• Finish that survives a workshop — painted green and grey over machined surfaces, with the speed chart, threading chart and safety labels on the headstock panel where they can be read at a glance.

Key Specifications

Threading, Feeds & Speeds

• Eight spindle speeds from 84 to 1850 rpm — the low steps carry large-diameter work and heavy roughing; the top steps suit small diameters, aluminium and finishing passes where surface speed matters more than torque.
• Four thread systems on one chart — 26 metric pitches from 0.4 to 7 mm, 34 imperial from 4 to 56 TPI, 16 module from 0.35 to 5 MP and 36 diametral from 6 to 104 DP, following the same four-system convention cnc turning machine manufacturers print on their own machines, so a fitter can read the chart without a manual.
• Longitudinal and cross feeds — 0.052 to 1.392 mm per revolution along the bed and 0.014 to 0.38 mm per revolution across it: fine enough for a finishing pass, coarse enough to move metal on a roughing cut.
• Lead screw and half nuts — a 22 mm lead screw with a 3 mm or 8 TPI pitch, engaged through the apron for thread cutting.
• Travels that use the whole bed — 1000 mm of saddle travel, 160 mm of cross travel and 70 mm of compound travel, so a long shaft can be worked in one setting.
• No program needed for a thread — on a lathe cnc machine the pitch is a value keyed into a screen; here it is read from the threading chart and set on the machine, which is why a one-off thread is often quicker by hand.

Product Advantages

Setup measured in minutes, not in a program

A one-off job starts when the part is chucked. Feed, speed and depth of cut are set on the machine, the first cut is taken, and the dial is adjusted from what the cut tells you. An industrial metal lathe is meant to absorb exactly that kind of work, and for repair jobs and short runs it is usually the difference between a part that ships the same day and one that waits for a slot on a programmed machine.

Rigidity carried in the casting

A wide, deep bed and a short overhang from the spindle are what stop a finishing pass from turning into chatter. This machine is built to take a real depth of cut in steel rather than to be babied through aluminium, and that shows up in the surface finish of the parts that matter.

Torque where the work is heavy

The eight-step geared headstock keeps torque available at low spindle speed, which is where large-diameter work lives. Instead of running a small motor hard at the bottom of its range, the machine is geared for it.

A second machine that protects the first

In a shop that runs a cnc turning machine, the manual lathe quietly becomes the busiest machine on the floor. Rework, fixtures, one-offs and the odd thread all land here, and the programmed machine stays free for the batches it was bought for.

A specification you can hold someone to

Bed width, spindle taper, thread range and motor size are the numbers that decide whether a lathe suits a job, and they are listed with the machine rather than left to a phone call. Buyers comparing quotes from several cnc lathe suppliers find that this shortens the decision considerably.

Built to be repaired, not replaced

Nothing here needs a service contract to keep running. Bearings, belts, the control board and the motor are accessible, and our service team keeps parts moving for the models we supply.

Workshop Use Scenarios

1. Repair and maintenance shops — a worn shaft is built up, re-cut and returned to service; a housing is bored and sleeved; a flange is faced square again. The work arrives without warning and usually leaves the same day.
2. Production support — where the cnc turning machine is booked solid on a batch, the one-offs, the fixtures and the rework come here instead of waiting their turn in a queue.
3. Prototype and development work — a new design goes from drawing to part in an afternoon, so a fit or a thread can be proved before anything is committed to a production run.
4. Training rooms and apprenticeships — feed, speed, tool geometry and thread cutting are visible and immediate on a manual metal lathe, and a mistake shows up on the part rather than in a line of code.
5. Dealers and resellers — agents and distributors who already carry a CNC range often add a manual model for customers whose work is repair rather than production, and a full specification makes the catalogue entry straightforward.
6. Agricultural and plant repair — hydraulic rams, linkage pins, shaft ends and threaded fittings are everyday work, and most of it can be turned on a machine of this size rather than sent away. Shops that buy from cnc lathe suppliers for production still keep one of these for the field-repair side of the business.

Ordering & Delivery

Setup, Care & Spare Parts

1. Put it on a floor that will not move — a solid, level surface with clearance at the headstock end for long bar and behind the bed for the chip tray. A machine that settles unevenly will cut a taper no matter how careful the operator is.
2. Level the bed before the first cut — this is the step most buyers skip, whether they are moving up from a smaller lathe or stepping across from a cnc machine lathe. Take the time, use a precision level, and recheck after the first week.
3. Check for transit movement — chuck, tool post, tailstock and carriage should all move freely by hand before any power is connected.
4. Fill and check the fluids — lubricant where the manual specifies it, coolant in the tank, and confirm the pump delivers to the tool before a real job goes in.
5. Connect power and check rotation — run the spindle in a low step first and confirm it turns the correct way before taking a cut.
6. Take a test cut instead of taking the machine apart — every machine ships pre-adjusted and calibrated, so accuracy is verified with a cutting test on a piece of bar. Dismantling the machine to check it yourself takes you outside that assurance.
7. Set a daily routine — wipe and oil the bed ways at the end of a shift, clear chips from the tray, and check coolant flow. Ten minutes a day is what keeps a lathe accurate for years.
8. Keep the paperwork with the machine — the manual covers lubrication points and adjustments, and our service team can supply the parts list and the electrical diagram. These are the same checks cnc turning machine manufacturers publish for their own models, and having them to hand shortens any conversation about a fault.

Bed Gap & Swing Capacity

• A removable section, not a hole in the bed — the gap piece sits in the bed directly in front of the headstock and comes out by releasing its cap screws. In place, the bed behaves like one continuous casting; with it out, the bed drops away under the chuck so a wide part can be mounted without fouling the ways.
• Three swing figures answer three different questions — 355 mm over the bed is the largest diameter that clears the ways anywhere along the bed. 220 mm over the carriage is the largest diameter you can turn with the carriage underneath it, and that is the number that governs shafts and any work turned along its length. 500 mm over the gap applies only to a short part held close to the chuck.
• Where the gap earns its place — a flywheel, a brake disc, a large pulley, a wide flange or a big-diameter sleeve that needs facing, boring or a register turned. These are parts too wide to pass over the carriage but far too short to need the length between centres.
• What it will not do — with the gap open there is no bed under the carriage, so the tool cannot travel across that section. Anything that has to be turned along its length still has to fit inside 220 mm over the carriage, whatever the gap figure suggests.
• The chucking method usually decides it — a large-diameter part held in the 160 mm three-jaw rarely needs the gap opened; it is normally a four-jaw or faceplate job where the part overhangs the chuck body, and that overhang is what the extra clearance is there for.
• Refitting is a cleanliness job — wipe the mating faces and the register before the gap piece goes back, seat it fully, then tighten the cap screws evenly. A chip trapped underneath shows up later as a dip in the surface finish as the carriage crosses the joint, so check the ways line up again before the next long shaft goes in.
• Slow the spindle and check clearance — a large diameter swung over the open gap puts a lot of mass on the spindle. Take light facing cuts at a low step, and turn the chuck by hand to confirm the jaws clear the bed before power goes on.
