This Pietro Carnaghi AC 20 TM 1800 is a CNC vertical turret lathe designed for turning, drilling, and milling operations. Manufactured in 2009 and overhauled in 2023, the machine features a robust rotary table with a diameter of 1800 mm, capable of handling a maximum workpiece weight of 5000 kg. The working height of the machine is 1270 mm, with a ram stroke of 1250 mm. The lathe is equipped with a powerful 100 kW table drive motor, providing a rotation speed range up to 320 rpm. It includes a Siemens 840 D CNC control system with four NC axes (X, Z, C, and crossbar adjustment), allowing precise and flexible machining. The travels include an X-axis range from -1650 to +2165 mm and a Z-axis travel of 1250 mm, with rapid traverse rates of 15 m/min. Tool management is facilitated by an 80-space chain magazine that accommodates 60 HSK 100 and 20 Capto C6 tool holders, along with a 12-position disc magazine for rotary holders and attachment heads. The machine also includes various drilling and milling heads, two measuring probes, and several turning tool holders. A notable feature is the pallet changer with two stations, each equipped with a faceplate of 1800 mm diameter and a six-jaw lever compensating chuck with mechanical centrifugal force compensation. The machine is installed in a pit and includes a coolant system with filter and circulation unit, chip conveyor, and oil-mist extractor. Recent maintenance includes replacement of the cross roller bearing and Siemens control components in 2023. The lathe is equipped with a measuring probe for tool measurement and an external Renishaw probe for workpiece measurement. Additionally, there is a measuring probe installed on the Z-axis for enhanced accuracy and efficiency, though it is currently shut down and may require overhaul before use. The machine is observed to be clean and well-maintained, with safety fencing and light curtains installed around the perimeter for operator protection. An overhead yellow crane system is present above the machine area to assist with lifting heavy parts. The CNC control panel is in good condition, featuring a display screen, keyboard, and an emergency stop button for safe operation. Used CNC vertical lathe for turning, drilling and milling

Various drilling and milling heads
2 measuring probes
Several turning tool holders
Special feature:
Pallet changer with two stations, equipped with a face plate
Ø1800 mm and a six-jaw lever compensation chuck with mechanical
centrifugal force compensation Ø1800 mm. Note:
The machine is in a pit. Condition description:
The cross roller bearing on the Carnaghi was replaced about half a year ago. The Siemens components in the control cabinet were also completely replaced at
the end of 2023. The machine also has a measuring probe for tool measurement
and an external Renishaw measuring probe for workpiece measurement. As a special feature, the machine also has a measuring probe installed on the
Z-axis
(Z1-axis). This brings an advantage in terms of accuracy and time, as the tool
does not have to be put down for measuring. However, it is currently shut down
and should be overhauled when it is put back into operation. The machine also
has a Rotomors six-jaw lever compensating chuck with centrifugal force
compensation, which was completely overhauled in 2020/21. Frequently Asked Questions (AI-Generated)
