Usage Procedure

1. Machine Preparation:

   • Make sure the lathe is properly aligned and leveled. Check the Fanuc CNC for proper operation and ensure all spindles and tool holders are in place.

2. Loading the Piece:

   • Place the workpiece on the spindles and secure it securely using the supplied clamping systems. Make sure the workpiece is properly aligned to avoid vibrations or machining errors.

3. CNC Setup:

   • Use the Fanuc CNC to program machining parameters, such as rotation speed and axis travel. Enter the necessary data and verify the settings.

4. Execution of the Process:

   • Start the turning process and monitor the operation through the CNC. Make any necessary adjustments to optimize the quality of the workpiece.

5. Final Inspection:

   • Once the machining is complete, inspect the piece to ensure it meets the required specifications. Remove the piece and proceed with cleaning the machine.

Matching Accessories and Equipment

• Turning Tools: To work different types of materials and obtain different finishes.
• Measuring Devices: To ensure precision in machining and maintain tight tolerances.
• Additional Supports: For pieces of non-standard shape or size, improving stability during machining.

Formulas for Optimal Use

• Cutting Speed ​​(Vc): Calculated to obtain an optimal result, it can be determined with the formula:
  Vc=π×D×N1000Vc = \frac{\pi \times D \times N}{1000}
  $V$ $c$ $=$ 1000 π × D × N ​where DD $D$ is the diameter of the workpiece and NN $N$ is the rotation speed in rpm.

• Feed per Revolution (f):
  f=VN×1000f = \frac{V}{N} \times 1000
  $f$ $=$ N V ​× $1000$ where VV $V$ is the feed and NN $N$ is the rotation speed.

Workable Materials

The Comec vertical lathe is suitable for working a wide range of materials:

• Metals: Steel, aluminum, copper and special alloys.
• Composite Materials: Depending on specifications and tools used.

Maintenance

• Regular Cleaning: Remove chips and dust after each use to maintain optimal operation.
• Lubrication: Be sure to keep components well lubricated according to the manufacturer's specifications.
• Periodic Inspection: Check the wear of tools and spindles to prevent problems during machining.

Evaluation of Good Used

To evaluate the quality of a used lathe:

• Check the General Condition: Visually examine the machine for any damage or wear.
• Test Operation: Run tests to ensure the lathe is operating properly and the Fanuc control is running smoothly.
• Review the Documentation: Make sure the manuals are present and that the machine has a declaration of conformity.

Sectors of Use

The Comec vertical lathe finds application in various sectors:

• Mechanical Industry: For the machining of large and heavy components.
• Aerospace Industry: For high-quality, precision parts.
