Mechanical Features:

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

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

• Peripheral Speed ​​of the Grinding Wheel: $V$
  • Where VV $V$ is the peripheral speed (m/s), DD $D$ is the diameter of the grinding wheel (m), and nn $n$ is the rotational 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 working 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 table guides and spindle bearings in tip-top condition.
• Checking and Rectifying the Grinding Wheel: The grinding wheel should be checked regularly to ensure it remains sharp and free from defects.
• Alignment Checks: Regular checks of the alignment of the grinding head and the workpiece ensure consistent accuracy.

Valuing a Good Used Car:

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

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