The Grazioli parallel lathe is a robust and high precision machine, suitable for those looking for reliable, used but still perfectly functional equipment. This model is known for its solidity and ability to process large pieces, making it ideal for workshops that need versatility in their work.
Visually, the Grazioli presents itself as a compact but robust machine, with a cast iron structure that guarantees stability and absorbs vibrations during processing. The distance between the centers is 2000 mm , offering considerable length for machining long and complex workpieces. The height of the centers is 250 mm , a fundamental parameter that defines the ability to machine pieces with a maximum diameter of approximately 500 mm .
The 80 mm bar passage allows you to insert large diameter bars, making this lathe ideal for processes that require bulky pieces. Furthermore, the machine is equipped with a height display , an extremely useful accessory for improving machining precision. This device allows you to monitor measurements in real time, making fine adjustments easier.
The Grazioli parallel lathe stands out for its mechanical characteristics which offer great versatility. The spindle is designed to support precision machining on both soft materials such as aluminum and harder materials such as steel or cast iron. Thanks to the dimension viewer , it is possible to reach very tight tolerances, making it perfect for precision machining that requires constant control of measurements.
Using the Grazioli lathe is simple but requires technical skills. Once the piece has been fixed between the centers or on the chuck, the speed and feed parameters are selected depending on the material to be machined. Thanks to the height display , the operator can monitor the progress of the turning process in real time, adjusting the settings to ensure maximum precision.
In addition to the height display, it is possible to combine the Grazioli lathe with various accessories, such as:
The basic formula for calculating the optimal cutting speed is:
Vc=π×D×n1000V_c = \frac{ \pi \times D \times n}{1000}
Where:
A used lathe like the Grazioli requires careful maintenance to ensure correct operation and prolong its useful life. It is important to regularly lubricate the guides, check the spindle transmission and check that the readout functions correctly. From a safety point of view, it is essential that the machine complies with current regulations, in particular with CE directives, although for a used machine it may be necessary to resort to updates to comply with modern regulations, such as the installation of additional protections.
To understand if the Grazioli lathe is a good used one, it is necessary to check some key aspects:
The Grazioli parallel lathe is widely used in the precision engineering , automotive , and aerospace . Buying a used Grazioli is an excellent investment because you get access to a quality machine at a lower price than new. Thanks to its robust construction, a good used one can continue to offer high performance for many years, allowing you to pay for your investment in a short time.
In conclusion, the Grazioli parallel lathe with a center height of 250 mm , center distance of 2000 mm and bar passage of 80 mm is a versatile and robust machine, ideal for precision machining in various industrial sectors. Buying it used represents an excellent deal for those looking for high performance at a low cost.
