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 machining of cylindrical workpieces. Manufactured by Fritz Studer AG , a leading manufacturer of grinding machines, this machine is particularly suitable for applications where quality and precision are essential.

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 may find Siemens or other control).

3. Components and Structure The Studer RHU 750 features a solid cast iron base, designed to minimize vibration and ensure optimal stability during machining. The spindle is mounted on high-precision bearings, ensuring smooth and precise rotation. The machine is equipped with a longitudinal table and an adjustable grinding head, allowing for internal and external grinding on a wide range of cylindrical components.

4. Mechanical Characteristics

• Precision: Thanks to its robust construction and accurate design, the RHU 750 guarantees extremely close tolerances in machining, making it ideal for finishing operations.
• Versatility: Although it does not feature an 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 Usage To calculate the optimal usage parameters of the grinding machine, the following formulas can 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 speed of the grinding wheel in revolutions per minute.
• Feed rate (f): This depends on the material being machined and the desired finish, but in general it should be optimized to avoid overheating and premature wear of the grinding wheel.

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

• Hardened steels
• Cast iron
• Non-ferrous metals (e.g. aluminum, bronze)
• Composite materials and plastics, if you use appropriate wheels.

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

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

8. Evaluating a Good Used Machine To evaluate a used grinder like the RHU 750:

• Machine condition: Check the wear of mechanical parts and the accuracy of the machine.
• Maintenance History: Request documentation of maintenance and repairs performed.
• Functional Test: If possible, perform a load test to evaluate the accuracy and effectiveness of the grinding.

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

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

10. Why Buy Used? Buying a used Studer RHU 750 can be an excellent investment for workshops and industries requiring high-precision cylindrical grinding without the high cost of a new machine. The robustness and longevity of these machines, combined with proper maintenance, guarantee reliable performance for many years.

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