Usage Procedure

1. Machine Preparation:

   • Make sure the lathe is properly aligned and level. Check the operation of the Fanuc CNC and make sure that all spindles and tool holders are in place.

2. Loading the Piece:

   • Place the workpiece on the chucks and clamp it securely using the clamping systems provided. Check that the piece is correctly aligned to avoid vibrations or machining errors.

3. CNC setup:

   • Use the Fanuc numerical control to program the machining parameters, such as rotation speed and axis travel. Enter the necessary data and check 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 workmanship.

5. Final Check:

   • Once processing is complete, inspect the piece to verify that 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 processing precision and maintain tight tolerances.
• Additional Supports: For pieces of non-standard shape or size, improving stability during processing.

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 piece and NN $N$ is the rotation speed in rpm.

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

Workable Materials

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

• Metals: Steel, aluminium, 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 manufacturer specifications.
• Periodic Inspection: Check the wear of tools and spindles to prevent problems during processing.

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.
• Verify Operation: Perform tests to ensure that the lathe is functioning properly and that the Fanuc control is operating without problems.
• Examine the Documentation: Make sure the manuals are present and that the machine has a declaration of conformity.
