SIM metal lathe

Feed values in material processing:

Processing Type / Lever Feed Rates
Finest finishing (red lever) 0.07 mm/rev – 0.035 mm/rev – 0.05 mm/rev
Standard turning (orange lever) 0.2 mm/rev – 0.1 mm/rev – 0.14 mm/rev
Roughing – heavy feed (green lever) 0.6 mm/rev – 0.3 mm/rev – 0.4 mm/rev

Cross feed (for grooving or facing operations) is half of the longitudinal feed with the same lever setup.

Additional data:

The lathe chuck is mounted via a flange plate directly onto the spindle.
Tool post: The machine features a quick-change tool post system, which significantly increases productivity.
Tailstock: Return center with Morse taper MT2 or MT3 – standard for this machine.
Spindle nose standard is Camlock D1-3″ or D1-4″.
Spindle nose diameter: 70.6 mm = Camlock D1-3″ or 82.6 mm = Camlock D1-4″.

Recommended cutting speed (Vc) for HSS tools:

Material Roughing (m/min) Finishing (m/min)
Aluminum 60 to 100 100 to 200
Brass (yellow) 50 to 70 80 to 120
Bronze 30 to 50 50 to 80
Mild steel (S235, Č0361) 25 to 35 40 to 60
Machinery steel (C45) 20 to 25 30 to 40
Grey cast iron (gus) 15 to 20 25 to 35
Stainless steel (Inox) 10 to 15 20 to 30

If you use carbide tipped tools (tungsten carbide), you can easily multiply these cutting speeds by 3 to 5.

Intended use: These lathes are known for being extremely robust and rigid (“monsters” in terms of stability), designed for mass production and heavy-duty machining tasks.
Key characteristic: Many models of SIM lathes (like the T-series) often lacked a built-in thread cutting mechanism, as they focused primarily on rapid and precise stock removal (high-speed turning).
Construction: The machine is made of one-piece cast steel for maximum rigidity, and the gears are lubricated through an internal hydraulic oiling system.

Today, SIM lathes are considered high-quality classic machines (“old school” engineering) which, if properly maintained, still deliver exceptional accuracy due to their heavy mass.
