used Comec vertical lathe, Thor model from 1998, is a robust and versatile machine, designed for complex machining. Its visually impressive structure is characterized by a double spindle and double turret, which allows simultaneous turning operations, ensuring greater productivity. The machine, of an industrial colour, typically gray or blue, stands out for the presence of two turrets with 8 positions each, for a total of 16 tools that can be mounted simultaneously. The Comec Thor provides an accessible work area, with a robust bench that can accommodate a maximum turning diameter of 375mm and a maximum turning length of 200mm.

The dimensions of the Thor lathe are significant: the machine measures 4,300 mm in length, 2,200 mm in width and 2,250 mm in height, with a total weight of approximately 7,300 kg. It is powered by a powerful 11 ​​kW spindle motor, which reaches a maximum rotation speed of 4000 rpm. The spindle is equipped with front bearings with an internal diameter of 100 mm, ensuring high precision and durability over time. Furthermore, the machine is equipped with a Siemens 810D , which guarantees precise management of the X and Z axes, which move at rapid speeds of up to 30 m/min. The diameter of the steerer is 115 mm, while the travel on the X and Z axes is 115 mm and 220 mm respectively.

Mechanical characteristics : the double spindle of the Comec Thor lathe allows fast and precise operations, ideal for mass production and complex pieces. Thanks to its double turret, it is possible to equip the lathe with a wide range of tools for different turning operations, allowing unrivaled operational flexibility. The presence of a VDI 30 tool disc is another advantage, allowing quick tool changes and improving overall efficiency.

Procedure for use : the lathe is operated via the Siemens CNC control, where the operator programs the required processes. After fixing the piece on the chuck, the lathe starts rotation and the turrets move in sync to carry out the turning operations. To optimize the use of the Comec Thor lathe, mathematical formulas can be applied that calculate the optimal cutting speed based on the material being processed, for example using the formula Vc=πDn1000V_c = \frac{\pi D n}{1000} $V$ c = 1000 π D n ​, VcV_c $V$ c ​is DD $D$ is the workpiece diameter and nn $n$ is the spindle speed.

Workable materials : the lathe is suitable for processing a wide range of materials, including steel, light alloys, cast iron and non-metallic materials, thanks to its power and precision.

Maintenance : being a used machine, it is important to regularly check its condition. Periodic maintenance interventions must include lubrication of the axes and spindle, cleaning of the turrets and checking the integrity of electronic and mechanical components, such as bearings and guides.

Sectors of use : the Comec Thor lathe is mainly used in the precision mechanical industry, in the production of components for the automotive, aerospace and machine tool industries.

Is it worth buying used? Certainly, because a robust machine like the Comec Thor can still guarantee years of efficient production, with significant savings compared to purchasing a new machine
