NUMOBAMS NU210LSE Double Chuck 1000mm Auto Left&Right Threading Making Manual Metal Lathe Machine Pool Cue Lathe Machine

Product Overview

A threading job rarely fails on the turning — it fails on the changeover. The NU210LSE is built around that problem: a 1000 mm between-centres metal lathe machine that selects metric and inch pitches electronically and cuts left- and right-hand threads without a gear swap, so the setup you prove on the first part still holds for the next ninety-nine.

Two chuck heads sit on the same headstock, with a 125 mm front chuck available as 3-jaw, 4-jaw or 6-jaw. One head can hold a bar for a thread run while the other stays set up for a second operation, or for the same thread cut in the opposite hand.

An 1100 W brushless motor turns a spindle with a 38 mm bore and an MT5 taper, which covers the studs, rods, bushings and fittings that come through a repair bench or a light production run. Carriage and cross slide work on handwheels, pitch and feed selection are electronic, and a digital readout is available if you would rather read a number than count dial graduations.

It suits a one- or two-person shop that threads parts regularly, a maintenance department making its own replacements, and a model engineer who has outgrown a small hobby lathe. Machines in this class are bought once and kept for years, so the questions worth asking are the ones few buyers put to a lathe machine manufacturer before ordering: what happens when a board fails, and where the replacement comes from.

Automatic Left & Right Threading

• Electronic change gears replace the gear train. Pitch selection happens on the control panel instead of at a stack of loose gears, so moving from one thread to the next is a selection rather than a strip-down.
• Left and right threads from one setup. Direction is switched electronically, which is what makes matched pairs practical — a left-hand and a right-hand tie rod, drawbar or linkage end run back to back without re-fixturing the part.
• A working chart in front of the operator. The headstock plate lists 20 metric and 23 inch pitches with the matching feed rates, so the settings come off the machine rather than out of a manual.
• A step up from a diy metal lathe. If your current machine needs a gear change and a fresh test cut for every new pitch, the time this gives back is the entire point.
• Fewer places to make a mistake. A correctly read chart paired with a wrongly stacked gear train is the most common cause of a bad thread; with no train to stack, that failure mode disappears.
• Value that shows up on the second part, not the first. Once a thread is proven with a light pass, each following part is the same selection and the same pass, which is exactly what a repeat run needs from a threading lathe.
• What the electronics do not do. The carriage is still moved by handwheel. Pitch and feed are electronic; the toolpath is the operator's. Prove every new thread with a light first pass.
• The real comparison point. Plenty of 1100 W lathes exist. What is harder to find from any single lathe machine manufacturer is electronic pitch selection plus bidirectional threading on a bench-sized machine. 

Dual Chuck Workholding

Two stations on one headstock

The headstock carries two chuck stations, and each can hold a workpiece at the same time. On a benchtop metal lathe that is unusual, and it changes how work is sequenced: a bar can stay gripped in one station while a second part is set up in the other, or the second head can hold the same part in a different attitude for a second operation. A changeover stops meaning a teardown of a setup you have just proven.

Choosing the front chuck: 3, 4 or 6 jaw

All three front chuck options are 125 mm, so the decision is about the work rather than the size. Three-jaw self-centring is the everyday choice for round and hex bar because it centres quickly and repeats. Four-jaw independent is what you want for square stock, off-centre boring and irregular castings, where each jaw is set separately. Six-jaw spreads clamping force over more contact points, which matters on thin-wall tube and on finished surfaces you do not want marked. If most of your work is round bar, order the three-jaw and add a four-jaw when an odd shape turns up.

Bar through the spindle

The 38 mm spindle bore lets bar pass through the headstock, so a long threaded rod is fed and re-gripped instead of cut short and joined. On repetition work that is often the difference between a two-setup job and a one-setup job on a metal turning lathe.

Safe handling at the chuck

Keep the chuck guard fitted for every operation, spin the chuck by hand before the first powered pass, and never leave a chuck key in a jaw. A 125 mm chuck at a few hundred rpm will take a sleeve with it.

Specifications

Shop Applications

• Repair and maintenance benches. Turning a replacement bushing or a shouldered shaft for a pump or gearbox that is already stripped down. The thread is usually the last operation and the reason the part is being made at all.
• Small-batch threaded components. Tie rods, clamp screws, studs and fittings run as a batch once the setup is proven — the bidirectional threading turns a paired-component job into one sequence on a single threading lathe.
• Home workshops and model engineering. A diy metal lathe user who has hit its limit on thread work will find 1000 mm of bed and a 38 mm bore a different class of job altogether.
• Prototype and product development. One-off parts where the thread profile and the fit both move between iterations, and resetting the machine has to be quicker than the cut.
• Training and shared workshops. Pitch and feed come off a chart, controls sit on a front panel with an emergency stop, and the machine teaches the same sequence a manual lathe teaches with fewer gear changes to get wrong.
• Plant, farm and hydraulic repair. Threaded rod ends, studs and adaptors made on site instead of ordered in and waited for.
• Where this machine stops. It is not built for three-shift production, for hard alloys at industrial depths of cut, or for work that needs a programmed toolpath. It also needs a solid bench and a way to lift it into place before delivery — a metal lathe machine of this size is not a one-person lift.

From Crate to First Cut

1. Check the crate against the packing list. The machine ships with a drill chuck, live centre, dead centre, a 7-piece turning tool set, spare jaws, the change gear set and a tool box. Note anything missing or damaged before you sign for the delivery.
2. Move it with help onto something solid. A benchtop metal lathe of this size needs a bench or stand that will not flex, and two people plus a lift or trolley rather than one pair of hands.
3. Level the bed before the first cut. A machine that rocks will cut a taper, and no dial adjustment later will correct a bed that is sitting twisted.
4. Confirm the supply before you switch on. Voltage, phase and plug type are matched to your location when the order is placed; check the plate on the machine against your own supply before the first start.
5. Fit the front chuck and dial it in. Spin it by hand first, then indicate a test bar so you know exactly where the machine is starting from.
6. Prove it with a test cut. Take a light pass on scrap and measure the result. That is how accuracy is verified — not by taking the machine apart.
7. Set one thread each way. Cut a right-hand thread, then a left-hand thread on the same bar and keep the chart settings with the job. The point of a metal turning lathe with electronic change gears is that the second direction costs nothing extra.
8. Keep the paperwork. The packing list and your settings sheet are what you go back to when a part needs replacing. We work with long-standing lathe machine manufacturers, so a worn jaw, centre or board can be matched to the machine that actually arrived.

Ordering & Delivery

1. Fix the configuration. Front chuck in 3-, 4- or 6-jaw, and whether you want the digital readout. Those are the two choices that change what arrives.
2. Tell us your supply and your address. Voltage, phase, plug type and the delivery address, so the machine is prepared for where it is going.
3. Confirm price and payment with our team. We quote per order and agree the payment method before the order is locked.
4. Dispatch takes place within 90 days of order confirmation.
5. Delivery is tax free and delivery to door service to the destinations we cover — confirm yours with us when you order.
6. Inspect on arrival. Check the crate against the packing list before signing, and photograph any transit damage.
7. Order parts when you need them. Jaws, centres, tooling and control boards are all available separately, so the machine stays in service.
