 Complete Operator Guide for Thread Rolling Machine – From Setup to Shutdown

Are you planning to buy a thread rolling machine for your business? If yes, the following piece is for you. Knowing all about the issues beforehand and being prepared for them will definitely help your business operations run smoothly without any disruption. Read on to know more. 

Step 1: Understanding Your Machine Before Switching It ON

Before touching any button, we at HTMT, one of the most trusted Thread Rolling Machine Manufacturers in India, suggest beginners do one thing:

Spend at least 10-20 minutes understanding the machine—it saves hours of mistakes.

Look at:

  • Rolling dies (flat / cylindrical / hydraulic)
  • Control panel
  • Lubrication points
  • Safety guards
  • Emergency stop button

It will help to analyse where are the buttons and what button work for what

Step 2: Selecting the Right Raw Material (Very Important)

Often questions like this get asked – ‘Can I roll threads on any rod?’ The answer is no, not every material is suitable.

For beginners, start with:

  • Mild steel
  • Carbon steel

Make sure:

  • Rod diameter is correct
  • The surface is clean
  • It has not any rust, bends or scratches

Wrong raw material = improper threads.

Step 3: Choosing the Correct Rolling Dies

90% of the beginners use the wrong die. And then ask, “Why are my threads not matching the sample?”

So before threading, kindly check the:

  • Thread pitch
  • Thread angle
  • Thread diameter
  • Left or right hand thread

Tip: Don't use the wrong die; it damages both the die and the machine.

Step 4: Installing and Aligning the Dies Properly

This is where beginners usually rush and pay later.

When installing dies:

  • Clean die holders properly
  • Tighten bolts evenly
  • Ensure perfect alignment

If dies are not aligned:

  • Threads will be uneven
  • One side will wear faster
  • Machine vibration will increase

Note: Alignment decides thread quality.

Step 5: Setting Machine’s Parameters

Some people generally ask, “Should I run the machine fast for more production?”

The clear answer is no. 

Start with:

  • Low speed
  • Moderate pressure

Once threads look perfect, you can slowly increase speed but not go for max speed.

Too much pressure causes:

  • Cracks
  • Flat threads
  • Die damage

Step 6: Applying Proper Lubrication

This step is often ignored by beginners—and that’s a big mistake.

Lubrication helps:

  • Reduce friction
  • Reduce overheating
  • Improve surface finish
  • Increase die life

Use:

  • Recommended rolling oil
  • Continuous lubrication during operation

Dry rolling = poor finish.

Step 7: Trial Run 

Note: Don’t skip this process

Before full production:

  • Run trial for 3-4 samples
  • Check the nature of the thread. 
  • Calculate the diameter

If you encounter some issue, unplug the power source. Continuing the operation might result in the malfunctioning of the machine.

Step 8: Continuous Monitoring During Production

Even after setup:

  • Watch machine sound
  • Observe thread finish
  • Check temperature

Any unusual noise or vibration is a warning sign of the machine.

Now Let’s Talk About Some Common Threading Defects

Also known as thread rollers, thread rolling machines may sometimes show operational issues. Here are some of those issues and solutions on how to fix them. 

1. Flat or Crushed Threads

Issues you face:

  • Thread tops look flat
  • Loss of sharp profile

Why it happens:

  • Excessive pressure
  • Over-rolling
  • Wrong die selection

How to fix it:

  • Reduce pressure
  • Adjust rolling time
  • Confirm correct die profile

2. Cracks on Threads

This scares beginners the most.

Issues you face:

  • Hard material
  • Excessive pressure
  • Poor lubrication

How to fix it:

  • Reduce pressure
  • Improve lubrication
  • Check material hardness

Thread rolling needs flexible material, not brittle.

3.‍‌‍‍‌‍‌‍‍‌ Uneven or Wavy Threads

Issues you face:

  • Un-uniformity of threads
  • Inconsistent Pitch

Why it happens:

  • Misplacement of die
  • Unwanted sounds from machine
  • Loose product accessories

How to fix it:

  • Place dies properly
  • Do not leave loose bolts
  • Check machine foundation

4. Poor Surface Finish

Issues you face:

  • Uneven threads

Why it happens:

  • Uncleaned dies
  • Bad lubrication
  • Worn-out dies

How to fix it:

  • Clean dies on a regular basis
  • Use correct lubrication
  • Replace damaged dies

5. Excessive Die Wear

Issues you face:

  • Hard material
  • Dry rolling
  • Over-pressure

How to fix it:

  • Follow pressure limits
  • Use proper lubrication
  • Don’t overload the machine

Powerful Maintenance Tips for Beginners

If you want consistent quality, always remember these things:

  • Clean machine daily
  • Lubricate moving parts
  • Inspect dies weekly
  • Train Thread rolling machine operators properly

Conclusion

If you are a beginner with a thread rolling machine or a thread roller, remember you don’t master the machine in one day.

You learn by:

  • Observing
  • Adjusting
  • Making small mistakes
  • Fixing the problem properly

Once you understand the basics, thread rolling becomes one of the most reliable and profitable operations in manufacturing.
