• Table: Dimensions 140 x 1300 mm, equipped with longitudinal and transverse movements to position and secure the workpiece.
• Grinding wheel: Dimensions 400 x 63 x 127 mm, spindle mounted, designed for precise material removal and surface finishing.
• Movement System: Allows for fine and precise adjustments to achieve the desired tolerances.
• Grinding Motor: Provides the power needed to drive the grinding wheel.

3. Technical Features

• Machine Weight: 2650 kg
• Table dimensions: 140 x 1300 mm
• Grinding Wheel Dimensions: 400 x 63 x 127 mm
• Table Movements: Longitudinal and transversal movement with micrometric adjustment.
• Grinding Wheel Speed: Typically variable, adaptable to the needs of the grinding process.
• Grinding Type: Tangential grinding, used to work flat surfaces.

4. Formulas and Parameters for Optimal Use

• Grinding Speed ​​(V): The grinding speed depends on the diameter of the grinding wheel and the spindle speed. The formula for calculating the peripheral speed of the grinding wheel is:
  V=D×π×N1000V = \frac{D \times \pi \times N}{1000}
  $V$ $=$ 1000 D × π × N ​Where

  • DD $D$ = Diameter of the grinding wheel in mm (400 mm)
  • NN $N$ = Grinding wheel speed in rpm

• Depth of Cut (d): The depth of cut must be adjusted according to the material and the required tolerance. The formula is:
  d=FAd = \frac{F}{A}
  $d$ $=$ A F ​Where

  • FF $F$ = Cutting force in N
  • AA $A$ = Contact area in mm²

• Feed (a): The machine feed should be set according to the desired finish. Typically, the feed can vary from 0.02 mm per pass to higher values ​​for faster material removal.

5. Workable Materials

The URS 751 grinder is designed to machine a wide range of metals and alloys, including:

• Steels
• Aluminum alloys
• Brass
• Durable metals and special alloys

The choice of grinding wheel type and grinding material depends on the type of material to be worked and the desired result.

6. Maintenance

• Lubrication: Check and maintain the machine's lubrication system. Use oils and greases recommended by the manufacturer.
• Inspecting the Grinding Wheel: Regularly check the condition of the grinding wheel for any signs of wear or damage.
• Cleaning: Keep the machine and table clean to avoid the accumulation of chips and dust that can compromise accuracy.
• Motion Control: Make sure all table and grinding wheel movements are smooth and vibration-free.

7. Used Vehicle Verification

• Wear Check: Check the condition of the grinding wheel and other components for wear and damage.
• Operation Tests: Test the machine to ensure that all functions are operational and that grinding is smooth.
• Component Condition: Check the drive system, movement mechanisms and lubrication system for signs of wear or malfunction.
• Documentation: Request documentation of previous maintenance and any repairs performed.

8. Sectors of Use

• Mechanical Industry: For the grinding of precision mechanical components.
• Automotive Industry: For the machining of engine parts and other components.
• Aerospace Industry: For finishing precision parts requiring close tolerances.

9. Why Buy Used?

• Lower Cost: Buying a used grinder like the Ziersch & Baltrusch URS 751 is cheaper than buying a new one.
• Reliability and Durability: Machines like this, if properly maintained, can provide years of reliable service.
• Historical Value: Well-built machines like this one have proven their reliability over time and can deliver high performance even after many years of use.
