CJWinter is excited to announce that we’ll be starting a new how-to video series in order to make the operation, rebuilding, setting, and/or recalibration of our attachments more accessible and easier to understand.

The first video in this ongoing series deals with taper setting adjustments on pneumatic attachments.

• Eliminates side pressure on spindles and other parts
• Allows for longer length and diameter rolling

Quick adjustments of pitch diameter

• Users can make adjustments within .0002 inch without stopping

Patented roll compensator

• Simplifies roll timing
• Ensures perfect roll synchronization
• Eliminates flaking
• Allows for roll timing adjustments in the machine without disassembling gears

Single cam for entire size range

• Allows for significant cost savings

Quick adjustments of penetration (roll feed) rate

• Eliminates the risk of unnecessary downtime

Chip purge line

• Keeps the gear train free of chips, which minimizes the cost and need for replacements

Quality components

• 100% complete interchangeability for replacement parts
• Zero time wasted on retrofitting

Secondary threading

• Allows an inexpensive lathe to be used as an auxiliary thread rolling machine

How-To adjust and set taper setting on pneumatic attachments

Double Dog Point Vs. Tapered Set Screw Attachments

There are two basic types of taper setting mechanisms in our pneumatic attachments: double dog point and tapered set screw. Learn more about these two options below.

Type A — Double Dog Point is found in our 125 Series, 141/151 Series, 160/170 Series

Tools needed for this type of attachment include: surface plate, Allen wrench, adjustable indicator stand, .0001-inch resolution indicator, and riser block (2 inches x 2.5 inches x 6 inches).

To make taper setting adjustments on this pneumatic attachment, users must follow these step-by-step instructions:

1. Remove thread rolls.
2. Place attachment on rise block.
3. Indicate the carbide roll pin on both sides to assess parallelism.
4. Loosen taper adjust set screw with an Allen wrench, and move accordingly.
5. Tighten the locking set screw to secure carbide roll pin
6. Re-indicate, zeroing on the immobile pin side.
7. Indicate the moving side, and document reading.
8. Repeat steps 2 - 7 required taper is achieved.
9. Do the same on the other arm.

Type B — Tapered Set Screw is found in our 134 Series, 162/172 Series

For this type of attachment, users require the following tools: surface plate, Allen wrench, flat-bladed screwdriver, adjustable indicator stand, .0001-inch resolution indicator, and riser block (2 inches x 2.5 inches x 6 inches).

Taper setting adjustment instructions are as follows:

1. Remove thread rolls.
2. Place attachment on rise block.
3. Indicate the carbide roll pin on both sides to assess parallelism.
4. Loosen locking set screw with an Allen wrench.
5. Pull out carbide roll pin.
6. Turn the taper set screw in or out one revolution.
7. Slide the carbide roll pin back in.
8. Tighten down the lock-in set screw.
9. Re-indicate, zeroing on the immobile pin side.
10. Indicate the moving side, and document reading.
11. Repeat steps 2 - 10 until required taper is achieved.
12. Do the same on the other arm
