Mechanical Characteristics

The GE MAC C 200-300 features a micrometric feed system with precise increments, typically in the order of 0.01 mm. This allows for precise control during grinding and lapping, ensuring an excellent surface finish.

Optimal Use Parameters

To determine the optimal parameters of use, the peripheral speed of the grinding wheel can be considered, which can be calculated using the formula: Vp=π⋅D⋅N60V_p = \frac{\pi \cdot D \cdot N}{60} $V$ p ​= 60 π ⋅ D ⋅ N ​where

• VpV_p $V$ p ​is
• DD $D$ is the diameter of the grinding wheel in meters,
• NN $N$ is the rotation speed of the grinding wheel in revolutions per minute (RPM).

Maintenance

Regular maintenance is crucial to maintain the performance of your machine:

• Lubrication: Regularly check lubricating oil levels in bearings and other moving components.
• Cleaning: Remove machining residues from the magnetic chuck and guides.
• Wear Control: Monitor the wear of the grinding wheel and replace it when necessary to maintain working accuracy.

Buying Used: What to Consider

When considering purchasing a used floor grinder like the GE MAC C 200-300 , it is important to:

• Check the condition of the magnetic chuck and the grinding wheel.
• Check the structural integrity of the machine, making sure there are no cracks or deformations.
• Make sure the electrical and refrigeration systems are working properly.

Sectors of Use
