Good news for those processing flame-cut parts with high thickness tolerances and significant warping. MK float, WEBER's latest development, makes deburring and rounding such workpieces a breeze. Visitors to Euroblech 2024 can see the performance of the MK float in action in Hannover.

Large-format flame-cut parts have often been difficult or even impossible to machine deburr effectively. High thickness tolerances and especially the significant warping of workpieces overwhelm the machines available on the market. This is now a thing of the past, as WEBER offers the solution with the new MK float.

First, the machine captures the shape of the workpiece non-contact at the machine inlet. The electronic unit control then activates the processing of the workpieces only at the edges.

 

Up to 10 Millimeters of Part Warping

One of the features of the MK float is that the force exerted by the individual planetary heads and segments of the grinding beam is pneumatically controlled. This ensures uniform processing of workpieces - even with a warping of up to 10 millimeters. It also prevents overloading of the tools, which makes the whole process feasible. Additionally, this method drastically reduces energy consumption and increases tool life.

 

The machine, which WEBER will demonstrate at Euroblech in Hannover, is equipped with the following units:

• float Slag Removal Unit
• Cross Grinding Unit with float bolt grinding beam

• float Planetary Rounding Unit for removing secondary burrs and rounding workpiece edges

   

Technical Background

 A cross grinding unit is necessary because a wide belt is not suitable for compensating up to 10 millimeters. However, the unit uses only half the width of the cross belt for processing the workpiece, keeping the leading edge of the belt always above the incoming workpieces. This allows for multi-lane loading of parts with large thickness variations or warping, without risking the threading of the grinding belt edge. To ensure the cross belt wears evenly and high-performance grinding belts can be used without excessively increasing costs, the machine control prompts the operator at set intervals of several hours or shifts to turn the belt to use the other half.

 

Special Feature of the Controlled float Planetary Rounding Unit

In uncontrolled rounding units, the tools must cope with thickness tolerances, leading to highly uneven rounding results. In contrast, the controlled float version achieves uniform rounding and high tool life.
