Centre Lathe with Lead Screw and Feed Shaft DM 900 V-D / 230 V with...
Description
The M4P DM 900 V-D / 230 V lathe with SL 12 stand is a centre lathe with lead screw and feed shaft: 900 mm between centres, 320 mm swing over bed, 38 mm spindle bore, three-phase motor with inverter powered at 230 V and digital readout as standard. Distributed in Italy by Krollit, official M4P distributor.
Key features
- Three-phase motor with inverter: 230 V power supply, higher output power and high torque
- Continuously variable speed in two ranges, 75–500 and 300–2,000 rpm, with digital speed display
- 38 mm spindle bore and D1-4 spindle mount (DIN 55029), for machining large-diameter shafts
- Lead screw and feed shaft: 15 longitudinal feeds, 15 cross feeds, 18 metric and 21 inch threads
- Induction-hardened and ground prismatic bed, with a large support surface
- Spindle on two adjustable precision tapered roller bearings class P5, concentricity better than 0.015 mm
- SDS6-3V digital readout, micrometer longitudinal stop and safety clutch as standard
- Quick-change tool post QC200, LED work light and SL 12 stand included
Who uses it
The DM 900 V-D is designed for machine shops, maintenance departments, precision engineering workshops, schools and training centres, as well as demanding hobbyists. It machines steel, non-ferrous metals and plastics and, thanks to the separate lead screw and feed shaft, handles both turning with automatic feed and threading. The 230 V power supply means it can be installed even where three-phase power is not available.
Position in the range
The DM 900 V-D is the digital readout version of the DM 900 V lathe. Compared with the DM 400 V-D bench lathe, it offers twice the distance between centres (900 mm versus 400 mm), a larger swing (320 mm versus 200 mm), a 38 mm spindle bore, a feed shaft for automatic cross feeds and an included stand.
Optional accessories
- Fixed steady and travelling steady for DM 900 V
- Live centre MT 3, also with 7 interchangeable inserts
- Rotating centring cone MT 3 / 100 mm
- 4-station MT 2 turret with inserts
- 5C collet chuck with D1-4 mount and set of 24 5C collets from 3 to 26 mm
- 10-piece centre drill set
- Set of lathe tools with 12 mm carbide inserts (5 or 9 pieces)
- Universal coolant system with 10-litre tank, 230 V

Frequently asked questions
Does the DM 900 V-D work on single-phase power?
Yes. The lathe runs on 230 V: a Delta inverter controls the 1.5 kW three-phase motor, ensuring high torque and continuously variable speed.
What is the difference between the lead screw and the feed shaft?
The lead screw is used for threading, the feed shaft for automatic longitudinal and cross feeds. Keeping them separate preserves the accuracy of the lead screw over time.
What are the maximum workpiece dimensions?
The distance between centres is 900 mm and the swing over bed is 320 mm. The 38 mm spindle bore allows bars up to this diameter to pass through.
Which threads can be cut?
18 metric threads from 0.2 to 3.5 mm and 21 inch threads from 8 to 56 threads per inch, with thread dial indicator supplied.
Is the stand included?
Yes. The SL 12 stand is part of the scope of delivery; with the stand the machine measures approx. 1,650 × 700 × 1,620 mm and weighs approx. 308 kg.
How accurate is the spindle?
The spindle runs on two adjustable precision tapered roller bearings, with a spindle nose concentricity better than 0.015 mm.
Which materials can I machine?
Steel, non-ferrous metals such as aluminium and brass, and plastics: longitudinal and facing turning, boring and threading.
What is included in the scope of delivery?
Digital readout, 160 mm 3-jaw chuck, dead centres, QC200 quick-change tool post, safety clutch, micrometer stop, inverter, speed and thread indicators, LED light, guards, SL 12 stand and service tools.
How is the machine delivered?
The machine weighs approx. 308 kg and is delivered on a pallet by truck with tail lift, within 5–9 working days.
