3. Configuración

Before beginning any thread cutting operation, ensure you have the correct tap or die for the desired thread size and pitch. Always wear appropriate personal protective equipment, including safety glasses and gloves.

3.1. Preparing for Tapping (Internal Threads)

1. Select the appropriate tap size (e.g., M6) and the correct sequence (pre-cutter, mid-cutter, finish-cutter).
2. Insert the tap into the tap wrench. Ensure it is centered and securely tightened.
3. Drill a pilot hole of the correct diameter for the desired thread. Refer to standard tap drill charts for accurate sizing.
4. Chamfer the edge of the drilled hole to facilitate tap entry.

3.2. Preparing for Die Cutting (External Threads)

1. Select the appropriate die size (e.g., M6).
2. Insert the die into the die stock. Ensure it is seated correctly and the retaining screws are tightened to hold it firmly.
3. Prepare the rod or shaft by chamfering its end to aid in starting the die. The diameter of the rod should be slightly less than the nominal thread diameter.

4. Instrucións de funcionamento

Thread cutting requires precision and care. Always apply cutting fluid to reduce friction and heat, and to improve thread quality and tool life.

4.1. Tapping Procedure

1. Position the pre-cutter tap squarely over the pilot hole. Apply light downward pressure.
2. Rotate the tap wrench clockwise (for right-hand threads) slowly and steadily. Ensure the tap enters straight.
3. After every half to full turn, reverse the tap wrench a quarter turn to break chips and clear the flutes.
4. Continue this process, applying cutting fluid regularly, until the desired thread depth is achieved.
5. Repeat the process with the mid-cutter and then the finish-cutter taps for a complete and accurate thread.

4.2. Die Cutting Procedure

1. Place the die stock with the die squarely onto the chamfered end of the rod. Apply firm, even pressure.
2. Rotate the die stock clockwise (for right-hand threads) slowly and steadily. Ensure the die starts straight.
3. After every half to full turn, reverse the die stock a quarter turn to break chips and clear the die.
4. Continue this process, applying cutting fluid regularly, until the desired thread length is achieved.
5. Use the thread gauge to verify the pitch and quality of the newly cut thread.

5. Mantemento

Proper maintenance ensures the longevity and performance of your thread cutting tools.

• Limpeza: After each use, thoroughly clean all taps, dies, and accessories to remove metal chips and cutting fluid residue. Use a brush and a suitable cleaning agent if necessary.
• Lubricación: Apply a thin coat of rust-preventative oil to all metal components before storage, especially to the cutting edges of taps and dies.
• Almacenamento: Always store the tools in their original metal case. The case protects the tools from damage, dust, and moisture, which can lead to corrosion and dulling of cutting edges.
• Inspección: Periodically inspect taps and dies for signs of wear, chipping, or damage. Dull or damaged tools should be replaced to prevent poor thread quality and potential tool breakage.
