Technical Data Sheet: Used Cylinder Grinding Machine - Fritz Studer RHU 750

1. Introduction The Fritz Studer RHU 750 is a precision cylindrical grinding machine used for high-precision mechanical machining of cylindrical workpieces. Produced by Fritz Studer AG , a leading company in the production of grinding machines, this machine is particularly suitable for applications where quality and precision are fundamental.

2. Technical Specifications

• Maximum grinding diameter: 250 mm
• Maximum grinding length: 750 mm
• Maximum workpiece weight: ~250 kg
• Main engine power: 3 kW
• Machine dimensions (WxDxH): 2400 x 1300 x 1500 mm
• Machine weight: 2200 kg
• Control system: Not equipped with advanced CNC control (for specific models you can find Siemens or other control).

3. Components and Structure The Studer RHU 750 is composed of a solid cast iron base, designed to minimize vibrations and ensure optimal stability during processing. The spindle is mounted on high-precision bearings, which ensure smooth and precise rotation. The machine is equipped with a longitudinal table and an adjustable grinding head, which allow internal and external grinding to be carried out on a wide range of cylindrical components.

4. Mechanical Characteristics

• Precision: Thanks to its robust construction and accurate design, the RHU 750 guarantees extremely low tolerance in machining, making it ideal for finishing operations.
• Versatility: Although it does not feature advanced CNC control, the machine is flexible enough to handle various types of materials and part shapes when used by experienced operators.

5. Formulas for Optimal Use To calculate the optimal use parameters of the grinding machine, the following formulas may be useful:

• Cutting speed (V): V=π×D×n/1000V = \pi \times D \times n / 1000 $V$ $=$ $\pi$ $\times$ $D$ $\times$ $n$ $/1000$ , where DD $D$ is the diameter of the grinding wheel and nn $n$ is the grinding wheel speed in revolutions per minute.
• Feed speed (f): depends on the material being processed and the desired finish, but in general it should be optimized to avoid overheating and premature wear of the wheel.

6. Workable Materials The RHU 750 is suitable for processing a wide range of materials, including:

• Hardened steels
• Cast iron
• Non-ferrous metals (e.g. aluminium, bronze)
• Composite and plastic materials, if appropriate grinding wheels are used.

7. Maintenance To keep the RHU 750 in optimal condition:

• Regular lubrication: Make sure all moving parts are properly lubricated.
• Checking the grinding wheels: Check the wear of the grinding wheels and replace them when necessary.
• Cleaning: Keep the machine clean of dust and chips to prevent damage to internal components.
• Alignment: Periodically check the alignment of the spindle and grinding head.

8. Evaluation of a Good Used To evaluate a used rectification such as the RHU 750:

• Condition of the machine: Check the wear of the mechanical parts and the precision of the machine.
• Maintenance history: Request documentation relating to maintenance interventions and repairs carried out.
• Functional test: If possible, carry out a test under load to evaluate the precision and effectiveness of the grinding.

9. Sectors of Use The RHU 750 is mainly used in the following sectors:

• Precision mechanics
• Automotive industry
• Production of tools and moulds
• Aerospace sector

10. Why Buy It Used Buying a used Studer RHU 750 can represent an excellent investment for workshops and industries that need high precision cylindrical grinding without facing the high costs of a new machine. The robustness and longevity of these machines, combined with appropriate maintenance, ensure reliable performance for many years.

Buying a used machine also allows you to reduce waiting times for delivery, being able to find models available immediately on the market.
