This Stama MC 535-TWIN is a used machining center — sometimes referred to as a CNC machining center or machining centre — dating from 1999 and currently located in Germany. Machining centers are multi-axis machine tools designed to perform a range of metal-cutting operations including milling, drilling, and tapping in a single setup, and Stama is a German manufacturer well regarded for its twin-spindle and multi-spindle machining solutions, serving industries that demand high-throughput precision part production.
The machine is configured as a high-performance driving-column machining center with twin main spindles, each driven by a dedicated Kessler motor rated at 21 kW and capable of reaching 15,000 rpm. Spindle speed range spans 36 to 10,000 rpm across 36 steps, with a maximum torque at the spindle of 102 Nm and a tool clamping force of 12,000 N. Tooling is carried on an SK40 taper, and the automatic tool changer accommodates 42 tools.
Axis travels measure 800 mm in X, 500 mm in Y, and 510 mm in Z. Feed rates are variable from 1 to 10,000 mm/min on all three axes, and rapid traverse is a uniform 40 m/min across X, Y, and Z. Each linear axis is driven by a dedicated Siemens motor: the X and Y axes produce 14.0 Nm of torque, while the Z axis delivers 17.6 Nm, all at a rated speed of 3,000 rpm. The control system is a Siemens Sinumerik 840D.
Cutting capacities include a maximum milling capacity of 400 mm, a maximum drilling diameter of 50 mm, and a maximum thread size of M30. Total connected power requirement is 70 kW at 400 V / 50 Hz.
The machine is equipped with a coolant system featuring a paper-band conveyor, a Flender chip conveyor (MC535, X = 800), a HAWE hydraulic aggregate, and a Promo loading system.
