Specifically built to reduce the physical burden of finishing, protecting your team from long-term strain.

TopEdge | Precision Edge Milling & Weld Preparation
The TopEdge is a robust, semi-automatic milling machine designed for manufacturers who demand perfection in beveling and edge rounding. By combining a counterbalanced arm with specialized milling technology, the TopEdge delivers industrial-grade results with a fraction of the physical effort required by handheld tools.
Superior Weld Preparation & Edge Rounding
The TopEdge provides the precision needed for high-strength manufacturing:
- Enhanced Welding Surface
Create precise bevels that increase surface area for better weld adhesion and deeper penetration, ensuring a stronger connection between plate parts. - Versatile Bevels & Radii
Easily mill a standard 45° bevel or apply a custom radius (R=2 to R=8). - Material Flexibility
Engineered for consistent performance on steel, aluminum, and stainless steel. - Universal Tooling
The convenient tool mount allows for rapid switches. The TopEdge is compatible with most premium milling tools, including industry favorites like BevelTools.
Effortless Operation & Ergonomics
We’ve engineered the TopEdge to protect your most valuable asset—your operators:
- Vibration-Free Precision
The balanced arm and milling head weight allow for high-accuracy work with minimal physical exertion. - Health & Safety
By significantly reducing vibration transfer, the TopEdge lowers the risk of occupational hazards such as HAVS (Hand-Arm Vibration Syndrome) and White Finger Disease (WVF). - Controlled Control
Standard two-hand operation ensures the machine is always used in a safe, controlled manner.
Advanced Workpiece Fixation
Stability is the key to a perfect mill. The TopEdge offers professional-grade clamping options:
- Welding Table Interface
The work surface features a standard hole pattern, allowing you to use your existing welding clamps to secure workpieces. - Optional Magnetic Table
For maximum efficiency with steel products, choose the electromagnetic table featuring a pull force of 300 kg per magnet for instant, rock-solid fixation.

SkipJoint | Precision Micro-Joint Removal
Tired of unwanted rounding and safety risks when removing micro-joints with a belt grinder? Meet the SkipJoint. This specialized solution is engineered to remove “witness joints” cleanly and square to the product, ensuring a perfect finish without compromising the part’s contour.
Why Switch to the SkipJoint?
Traditional belt grinding often results in inconsistent rounding and operator safety hazards. The SkipJoint solves this by providing:
- Perpendicular Precision
Using a vertical rotating disc and a horizontal infeed table, the machine removes joints perfectly square to the laser-cut edge. - Contour Protection
Unlike belt grinders, the SkipJoint removes only the tab, preserving the original geometry of your product. - Enhanced Safety
Equipped with a height-adjustable polycarbonate shield that matches your product’s thickness, ensuring your fingers are always protected.
What are Micro-Joints?
Micro-joints, or witness joints, are tiny uncut sections of metal that keep small parts attached to the sheet during laser or waterjet cutting. While necessary to prevent parts from falling into the cutting bed, they leave behind undesirable tabs. The SkipJoint removes these quickly, safely, and with minimal effort.
Flexible & User-Friendly Design
The SkipJoint is built to be as versatile as your production needs:
- Quick-Change Discs
The 255 mm hook-and-loop sanding discs are available in various grits and can be swapped in seconds. - Multi-Tool Capability
Beyond sanding discs, the machine can be equipped with polishing or deburring brushes for specialized finishing operations. - Ergonomic Infeed
The steel infeed table is designed for stability and can be folded down for extra convenience and space-saving.

From growing fabrication shops to large-scale manufacturers, operations that rely on clean edges and consistent surface finishes can benefit from the performance and reliability of Q-Fin systems.
