Circle Shear for Slitting Lines Cutting 0.15 mm Strip
At 0.15 mm the strip has almost no stiffness, so blade gap and overlap have to be set finely or the edge tears instead of shearing. This circle shear is configured for that gauge, trimming edge defects away so the strip does not break later in the line.
- Cuts strip down to 0.15 mm thickness
- Double head cantilever rotary hybrid power shear
- Double edged blades with end face grinding
- Width adjustment by two oil cylinders with servo control
Key Benefits
Why thin gauge trimming is its own problem.
Clean Edge On Very Thin Strip
Setting gap and overlap precisely produces a clean fracture rather than a torn edge at 0.15 mm.
Edge Cracks Removed Early
Trimming small edge defects prevents the strip breaking in follow up processes.
Repeatable Width Control
Servo cylinder control adjusts strip width precisely between products.
Where It Is Used
Line positions.
- Slitting lines for thin gauge strip
- Continuous processing lines in metallurgical plants
- Edge preparation before coiling
- Thin strip production for precision parts
Who It Is For
- Slitting line operators running thin gauge
- Processors of foil grade material
- Plants with edge tearing problems
- Buyers replacing a trimmer unsuited to thin strip
Problems It Solves
- Edge tearing instead of clean shearing
- Edge cracks causing strip breaks
- Width variation on thin strip
- Slow width changeover
Technical Features
Cutting principle.
Gap And Overlap Control
Two displacement and vertical circular blades are set to a defined gap and overlap, so the strip deforms at contact until it fractures.
Double Head Cantilever Structure
The rotary hybrid power shear arrangement carries both heads for simultaneous edge trimming.
Blade Service Features
Double edged blades with end face grinding and hydraulic nut locking allow quick change and regrinding.

Manufacturing Process
Gauge Review
Material, minimum thickness and trimmed width range set the blade configuration.
Frame And Head Manufacture
Heads are machined for precise blade alignment at fine gap settings.
Blade Production
Blades are hardened and ground for thin gauge shearing.
Assembly And Setting
Gap and overlap are set and the servo width control tested.
Quality Control
- Head alignment inspection
- Blade grinding and hardness records
- Gap and overlap verification at thin gauge
- Servo positioning accuracy test
Customization Options
- Trimmed width range for your products
- Blade specification for the gauge
- Drive package to line speed
- Interface to scrap handling equipment
Use Guide
- Set gap and overlap for each gauge, thin strip is unforgiving
- Regrind on the end face before the edge degrades
- Check blade concentricity when edge quality drops
- Keep the scrap path clear at thin gauge, edges tangle easily
How It Compares
Against heavier trimmers.
| Trimmers set for thicker strip | Gap and overlap settings for heavier gauge tear thin strip rather than shearing it. |
|---|---|
| Manual width setting | Servo cylinder control repeats the width setting exactly between products. |
| Leaving edges untrimmed | Edge cracks in thin strip cause breaks in the follow up processes. |

Circle Shear for 0.15 mm Strip Slitting Lines FAQ
How thin can it cut?
This configuration trims strip down to 0.15 mm. We confirm the range against your material and width.
How does the shearing work?
Two displacement and vertical circular blades are set to a defined gap and overlap. The strip deforms at the contact area until the pressurised part fractures.
How precise is the width setting?
Two oil cylinders adjust shearing width with servo cylinder control for precision and repeatability.
How often do blades need regrinding?
It depends on material and gauge. Blades are double edged with end face grinding so they can be turned and reground rather than replaced.
Do you supply the scrap chopper too?
Yes, trimming and scrap chopping are normally supplied together so trimmed edges are handled continuously.
What do you need to quote?
Material, thickness and width range, trimmed width range, line speed and layout.
