AUTOMATIC HEAD TRIMMING
TRIMMING MACHINE
HEX & POLYGON BOLT HEADS
The trimming machine gives a forged bolt head its final shape. It cuts the heads of cold forged blanks into hexagons and polygons and removes the flash left around the head, for a clean, uniform, professional finish.






ENGINEERED TO LAST
KEY FEATURES
Fully Automatic Operation
Continuous, automatic running that is simple to operate.
Precision Die & Punch
The head is pushed through a trimming die that holds tight tolerances and a fine finish.
Adjustable Cutting
Adjusts to trim different sizes and types of hex bolt heads accurately.
Precise Feeding
A feeding system ensures accurate positioning of bolt heads for trimming.
Standardized Output
Removes excess material precisely for standardized head dimensions critical to proper fit.
Low Cost Per Part
Low cost equipment for producing hexagon bolts in volume.
THE PROCESS
HOW IT WORKS
Forged Blank
The cold forged head still carries flash and excess material.
Feed to Die
The barrel shaped head is pushed into the trimming die.
Trim the Head
A trimming punch cuts the head to its hexagon or polygon shape.
Repeat if Needed
Complex parts can run twice, for example head then flange.
Continuous Output
Finished bolts feed through continuously at production speed.
