Applications and features
Self-Reversing Tapping Heads feature reversible rotation, overload protection, and adjustability. Their advantages include compact structures, high efficiency, safety and reliability, and simple operations.
Capacity range: Accusize Industrial Tools supplies three models of Self- Reversing Tapping Heads. The tapping capacity ranges from M2 to M20. The working range refers to the following table. Various adapters are available for the machines with different tapered spindles. Adapters with a taper of MS- JT/B or MS-M20 x2.5 are attached.

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, 45#, Ø20-30mm, HRC45), on the nonrotating 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.

Do not exceed the maximum speed of the tapping head. Speed is an important factor in tapping. Always follow the recommended speed table. Accusize 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.

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.

6.  To prevent the tap from hitting the bottom of the blind hole, set the machine stop correctly.
   Refer to controlled depth.

7. When tapping a blind hole, leave enough space for clearance.

8. ecure the work piece firmly so that it does not move, rotate, or lift.

9.  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.

10. 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 the 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.

11. 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.

To remove the taper mount arbor, strike the side of the arbor several times with a mallet.

Mount the Rubber Flex Collet into the tapping head nut
Put the rubber flex collet into the spindle hole

Screw the lock nut over the collet

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

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

Tighten the lock bolt with a wrench

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

d. Tighten the lock nut with a wrench

How to mount the stop arm:

The stop arm needs to be rotated to reverse the direction of the tapping head.

Recommended Tapping Speeds

The following table provides some general guidelines for tapping speeds. However, you should always follow the specific instructions from the tap manufacturer. Do not go beyond the maximum speed limit for the tapping attachment indicated on the sheet.

How to adjust the torque

Set the clutch so that it would prevent the tap from breaking and ensure the tap can cut as needed into the work piece. 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 TTT operator himself. For materials that are hard to tap, it is advisable to do two passes. JSN12-JT6

Tapping

The operator should align the tap on the machine 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 will keep tapping until it reaches the end of its extension, then it will automatically stop rotatin.

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

5. The raising speed of the machine spindle should match the retreating speed of the tap. Otherwise, the tap will stop and start intermittently

6.  The tap will 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

With cutting fluid, lower the tapping head to the workpiece to begin threading. The tap will automatically stop when it reaches the depth you had extended or allowed it. If more is needed, drop ever so slightly. Once the tap stops to the point where you feel the chip break is required to slightly lift (which will reverse the tap) to break thread chips and immediately lower the tap head to continue threading inward. The tapping head does not require any force to operate into or out of the part, be gentle and it will do the work for you and smoothly.
