This is a high speed precision lathe built to a very high standard and based around a deep webbed, cast iron bed with ground, induction hardened slideways providing great rigidity and strength. It is powered by a 2.2kW(415V or 230V) motor driving a headstock gearbox providing 8 speeds from 70-2000 rpm (230V) or 16 speeds, 35-2000 rpm (415V) through hardened gears. The spindle is carried on large taper roller bearings, has a D1-4 chuck mount and has a 38mm through bore with a 5MT in the nose. A very rigid carriage has power drive on the compound axis and is fitted with a 4-way tool post that can take tooling up to 16mm in size. The leadscrew pitch is 3mm and is driven by a gear box offering a choice of 32 ratios for general turning, and is easily reversible. The change wheel set provided offers a good range of thread cutting choices, 26 metric, 0.4-7mm pitch and 34 imperial, 4-56tpi. A thread dial indicator with 3 ratios is provided to assist in re-engaging the leadscrew in the correct position. There is a 2-axis DRO system included, featuring metric and imperial displays and linear compensation to enable a totally accurate measurement. The tailstock has a quick action camlock, a taper turning transverse adjustment, a fine pitch leadscrew for the barrel and a 4MT bore. The machine has 24V switch gear, a chuck guard interlock switch and a foot operated brake for safe operation. It comes with a comprehensive range of standard accessories including work lamp, rear splash back guard, cabinet stand with lockable cupboard, change wheel set, coolant pump and equipment, 150mm 3-jaw chuck with internal and external jaws, 200mm 4-jaw independent chuck, 250mm faceplate, live and dead centres, 5-3MT reduction sleeve, travelling steady, fixed steady and a toolbox with comprehensive tool kit plus spare brake shoes and operating cable. This machine is very suitable for educational establishments, maintenance workshops and small production workshops, and will prove to be a pleasure to use. N.B. Will require a 16A supply.

Have had the 330 for about 30 years Still as good as new.Quick Change Tool post Dixon type difficult to make tool holders unlike Aloris type which are very easy to produce. I have managed to make a few Dixon type but are quite complicated to produce. My Tailstock is still MT 3 probably old school. Also have the taper turning attachment which does not interfere with normal lathe use, But I prefer it off when I don't need it. I have the 3 Phase machine so speeds from 35 to 2000 Powerful motor fingers crossed never had any trouble. Headstock D1 - 4 but made an extention headstock taking all the chucks etc of my Emco Maximat V 10 p. helping to use smaller and lighter Chucks. Have an ER 40 collet chuck direct to the D 1 - 4 and an ER 25 with the Maximat Extension. Unfortunately there is no information regarding cutting metric module pitches, Was told a long time ago that if I wanted to cut a mod pitch to ask them for that specific information what gearing etc. to use, but I do not like having to ask Runmaster every time I need to cut a module Thread. The gear box could have been studied a bit better so fewer gear changes have to be made for Imperial Threads, as you have the 120 and 127 gears the selection for Imperial threads should be easier. I used to have in the old days (at my workplace) an old Colchester Mascot headstock bore 3 1/2 inch centre height about 8 1/2 inch where you could change from imperial to Metric just moving a lever, naturally the metric threads had to be cut without undoing the half nuts, but a a lowest speed of 30 could cut to a shoulder. It was an old machine but I used to cut 3/8 deep reducing material by 3/4 and even managed a couple of thou deep cuts.
