1. General Description

The Tripet MAR 200 internal grinding machine is a used machine designed for the internal grinding of cylindrical and conical components. This semi-automatic machine is particularly suitable for precision grinding operations on parts with internal cavities or holes. Thanks to its robust construction and semi-automatic capabilities, it is ideal for applications requiring a high-quality finish and tight tolerances.

2. Main Components

• Structure: Made of high-strength cast iron to ensure stability during grinding and to minimize vibrations.
• Grinding Spindle: Mounted to perform internal grinding of workpieces, with the possibility of adjustment to adapt to different working diameters.
• Movement System: Includes automatic and adjustable movements for the spindle and grinding head, to facilitate semi-automatic operation.
• Table and Supports: The machine table is designed to support the workpiece and allow for precise adjustments during grinding.
• Lubrication System: Keeps the spindle and other components lubricated to ensure optimal operation.

3. Technical Features

• Maximum Grinding Depth: 200 mm
• Machine Weight: 1200 kg
• Grinding Type: Internal, semi-automatic
• Movements: Semi-automatic, with micrometric adjustments to achieve precise tolerances.
• Grinding Diameter: Suitable for workpieces with an internal diameter that can be adjusted according to the machining specifications.

4. Formulas and Parameters for Optimal Use

• Grinding Wheel Speed ​​(V): The optimal grinding wheel speed can be calculated with the formula:
  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
  • NN $N$ = Grinding wheel speed in rpm

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

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

• Grinding Feed and Speed: Adjust the grinding feed and speed based on the part size and material. Specifications vary depending on finish and tolerance requirements.

5. Workable Materials

The Tripet MAR 200 internal grinder is designed to work various materials, including:

• High-strength steels
• Aluminum alloys
• Brass
• Hard metals and special alloys

The choice of material and type of abrasive depends on the type of surface to be worked and the degree of finish required.

6. Maintenance

• Lubrication: Check and maintain the lubrication system in good condition. Use oils and greases recommended by the manufacturer.
• Inspecting the Grinding Wheel: Check the condition of the grinding wheel regularly and replace it if it shows signs of wear or damage.
• Cleaning: Keep the machine clean to avoid the accumulation of chips and dust that can affect accuracy and performance.
• Movement Inspection: Ensure that all spindle and grinding head movements are smooth and vibration-free. Perform periodic inspections and adjustments as necessary.

7. Used Vehicle Verification

• Wear Check: Check the condition of the grinding wheel and major components such as the spindle and supports. Look for signs of wear or damage.
• Operation Tests: Test the machine to ensure that all functions are operational and that internal grinding is occurring smoothly.
• Component Condition: Check the lubrication system and movement mechanisms for any signs of malfunction or wear.
• Documentation: Request documentation of previous maintenance and repairs performed.

8. Sectors of Use

• Mechanical Industry: For the internal grinding of precision mechanical components.
• Aerospace Industry: For machining parts with tight tolerances and high-quality finishes.
• Automotive Industry: For finishing components with internal cavities or holes.

9. Why Buy Used?

• Lower Cost: Buying a used grinder like the Tripet MAR 200 is generally cheaper than buying a new one.
• Reliability: Well-built machines like this, if properly maintained, can provide years of reliable service.
• Historical Value: Quality interior grinders such as the Tripet MAR 200 have proven their ability to deliver excellent results even after many years of use.
