Warning:

To prevent serious damage and ensure optimal tapping performance, please read the operator and safety instructions provided for this device carefully. Also, follow all other relevant safety instructions, especially those related to your machine.

1. Suitable clothing: The rotating spindle of the machine tool can entangle loose clothing, jewelry, or long hair. Do not wear anything that may get caught, such as jewelry, long sleeves, ties, or gloves. Tie up long hair or use a hair net to avoid getting it wrapped around the rotating spindle.

2. Correct eye protection: Wear safety glasses with side shields to protect your eyes from flying debris.

3. Mounting the brake rod:
   Refer to Figure 1 and mount the brake rod, which should be rigid enough to withstand the torque of a reversing tap (a steel rod is recommended, 4511, 020-30mm. HRC45). on the non rotating part of the spindle end or on the worktable.
   

   • Do not modify the length of the standard stop arm in the attachment. A longer stop arm may pose a risk of hitting the operator and causing serious injury.
   • Do not grab the stop arm with your hand. When the machine reverses. the stop arm receives the full power and may hurt the operator severely.

4. Do not exceed the maximum speed of the tapping head. Speed is an important factor in tapping. Always follow the recommended speed table. Accurize Industrial Tools torque control reversing tapping attachment uses planetary gears to increase the reversing speed. The reverse rotation speed per minute out of the hole is 1. 75 times the spindle speed of the machine. We strongly suggest that you use the average tapping speed rather than the machine speed to calculate the cycle time. For example, if the machine speed is 1500 rpm, reverse speed is 2625 rpm, then your average tapping speed is 2062 rpm. You must not go beyond the maximum allowed speed marked on the tapping attachment.

5. Always be aware of the potential hazards of machining operation. When working with your machine, you may lose your attention and become complacent. This can lead to serious harm. Always pay attention to the dangers of the machine that you are using. As the machine spindle rotates, always keep your hands, body, clothing, jewelry and hair away from the operating area. The operating area includes the direct machining point and all transmission components including tapping attachment. Remember not to approach your hands, other parts of your body, or anything attached to you until the machine spindle completely stops.

6. Follow other relevant safety instructions and requirements, especially for your machine.

Essential Steps for Operation

1. Before using this tapping attachment, read the safety instructions for the product and machine carefully.
2. For optimal performance, ensure that the tap is sharp and aligned correctly.
3. The tap must be concentric with the hole.
4. Adjust the machine speed to the appropriate level.
5. Select the right feed speed based on the screw pitch and the revolutions per minute.
6. The drill size must be accurate.
7. To prevent the tap from hitting the bottom of the blind hole, set the machine stop correctly. Refer to controlled depth.
8. When tapping a blind hole, leave enough space for clearance.
9. Secure the work piece firmly so that it does not move, rotate, or lift.
10. Ensure that there is enough distance between the start and retract positions to keep the tapping head away from the hole as it retracts. Remember that the spindle extends when the tapping device reverses out of the hole.
11. Install a sturdy torque rod on the machine table or on the non-rotating spindle frame to prevent the stop arm from rotating. The torque rod strength must be greater than t he maximum tapping force of the cone. It must also have a smooth surface so that the stop arm can slide freely up and down in and out of the hole.
12. Use the proper cutting fluid/ lubricant for your application.

Self-reversing tapping heads are versatile tools that can be used on various machines with a rotating spindle, as well as for many automated tasks.

Procedure and Steps

1. Install the Arbor: Make sure the thread or taper of the arbor and the tapping attachment are clean. Then secure the arbor firmly on the tapping attachment.
   
   If the arbor has a taper, push and twist it into the tapping head, and then hit the end of the arbor with a mallet to fix it on the taper part of the tapping head.
   To remove the taper mount arbor, strike the side of the arbor several times with a mallet.

2. Mount the Rubber Flex Collet into the tapping head nut:
   
   Screw the lock nut over the col let

3. If the tap has a convex tip, grind it flat:
   **Eliminate any bumps on the tap

The square on the tap will be more fully gripped and stable
**

4. Mounting the tap:
   a. Loosen the lock bolt with a wrench

b. Insert the square end of the tap handle into the square hole of the clamping device

c. Tighten the lock bolt with a wrench

d. Tighten the lock nut with a wrench

5. How to mount the stop arm:
   The stop arm needs to be rotated to reverse the direction of the tapping head.

How to adjust the torque

You can choose a suitable torque level from numbers 1, 2, 3, 4 on the main body circumference based on the diameter and material of the work piece. The chuck can withstand different torque levels from low to high and can be adjusted by the operator himself. For materials that are hard to tap, it is advisable to do two passes.

Tapping

The operator should align the tap on the ma chine tool with the hole on the work piece that has been drilled for screwing and follow Figures 2.

1. Lower the spindle until the tap touches the workpiece.
   

2. Start tapping by moving the machine spindle down with the chuck
   

3. Stop the vertical movement of the machine spindle when it reaches the desired depth.
   The chuck spindle Willi keep tapping until it reaches the end of its extension, then it Willi automatically stop rotating.
   

4. Lift the machine tool spindle.
   Then the chuck spindle and the tap Wii automatically rotate in reverse and quickly retract.
   

5. The raising speed of the machine spindle should mate h the retreating speed of the tap. Otherwise, the tap wi II stop and start interim intently.
   

6. The tap Willi start rotating as soon as it has fully withdrawn from the workpiece.

Lubrication

Our products are pre-lubricated in the factory and are ready for use anytime. We recommend that you partially disassemble, clean and apply new grease to the product after 600 hours of use. We suggest using a high-quality lubricating grease.

Cutting Tool Lubrication
