• Table dimensions: 150 mm x 1255 mm
• Grinding wheel dimensions: 400 mm (diameter) x 50 mm (thickness) x 127 mm (hole)
• Installed Power: Variable depending on configuration (not specified)

Main Components:

1. Grinding Spindle: Designed to guarantee high stability and vibration reduction, essential for obtaining excellent quality surfaces.
2. Workpiece Holding Table: With generous dimensions, it allows you to handle pieces of various lengths and diameters with precision.
3. Lubrication System: Critical to maintain cooling and cleanliness of the grinding wheel during processing.
4. Control System: For the time, it could be manual or semi-automatic, with precision indicators for the positioning of the grinding wheel.

Mechanical Characteristics:

• Accuracy: Lizzini grinding is renowned for its ability to achieve extremely tight tolerances, often in the micron range.
• Rigidity: Heavy and rigid design minimizes vibration and deformation during operation.
• Wheel Rotation Speed: Important for optimizing the quality of the ground surface and the life of the wheel.

Mathematical Formulas for Optimization: To optimize grinding operations, it is important to consider:

• Grinding Wheel Peripheral Speed: $V$
  • Where VV $V$ is the peripheral speed (m/s), DD $D$ is the grinding wheel diameter (m), and nn $n$ is the rotation speed (rpm).
• Table Feed: Calculated to ensure a uniform finish, it is a parameter that must be optimized based on the material and specifications of the surface to be machined.

Workable Materials: The Lizzini RUL 60 M2 is suitable for processing metallic materials such as hardened steel, cast iron and non-ferrous alloys, making it versatile for a wide range of industrial applications.

Maintenance:

• Regular Lubrication: Essential to keep the table guides and spindle bearings in perfect condition.
• Checking and Grinding the Grinding Wheel: The grinding wheel must be checked regularly to ensure that it remains sharp and free from defects.
• Verification of Alignments: Regular checks of the alignment of the grinding head and the machined piece ensure constant precision.

Evaluation of a Good Used:

• Condition of Guides: Make sure the table guides are smooth and free from excessive wear.
• Checking the Spindle: Test the spindle for any play or abnormal vibrations.
• Condition of the Grinding Wheel: Check the wear and quality of the supplied grinding wheel.

Sectors of Use: The Lizzini RUL 60 M2 is widely used in the automotive, aerospace, and in general in all industries that require high precision components. It is particularly suitable for the production of high quality shafts, rollers and cylindrical parts.

Why Buy Used:

• Lower Cost: Purchasing a used machine like the Lizzini RUL 60 M2 can be very advantageous from an economic point of view, while still maintaining high quality.
• Reliability: Machines of this type, if well maintained, offer performance comparable to more recent models but at a decidedly lower cost.

The purchase of this used grinding machine can represent a significant opportunity for those looking for an excellent combination of quality and savings, especially if intended for precision machining that requires robust and reliable machinery.
