The KMB bench metalloscope is a magnetic inspection device featuring a highly functional and compact mechanical structure.

   

An important feature of the KMB metalloscope is its fast execution of inspections, allowing it to be implemented on all types of production lines for in-line inspection of printed pieces, loose pieces and small and large mechanically processed pieces for the automotive, aeronautical, rail and tram, naval, petrochemical, metallurgical and the iron and steel sectors.

 
   

Magnetic - electric inspections can be performed to detect any surface and subsurface defects, whether lengthwise, transversal or other, without need to move the piece blocked between the machine’s heads. The piece can be blocked quickly between the polar expansions as one of the latter is pneumatically fixed.

   

There are two main series of metalloscopes that differ essentially in their application method for transversal inspections (to be better described below). The KMB GM model has a magnetic yoke system for transversal inspection, while the KMB BE model uses a passing coil for the inspection.

   

The various models differ in terms of the permitted size of pieces for inspection, the heads'maximum opening span and the machine's power capacity.

MAGNETIZATION TECHNOLOGIES - Lengthwise magnetism flow inspection
     
     
Advantages:
- Allows for flow penetration far better than average.
- No impediment during loading or unloading of the piece, favouring manual spray operations.
Disadvantages:
- Greater density of magnetic powder on the two surfaces in contact with the piece, so more care is needed to detect micro-cracks at these points.
- More magnetic residue on the piece after inspection.
- Difficult to achieve a high degree of de-magnetization directly on the machine (in fact this type of set-up generally features de-magnetization units separate from the main device).
     
MAGNETIZATION TECHNOLOGIES - Magnetization with traversing coils (lengthwise flow)
     
     
Advantages:
- Homogenous distribution of magnetic particles all over the piece for inspection.
- Minimum magnetic residue on the piece after inspection.
- Potential for complete de-magnetization of the piece for inspection directly on the machine.
Disadvantages:
- If not applied with absolute accuracy, de-magnetization with external coil will not reveal defects of a certain depth.
- In many cases the external coil can complicate loading and unloading operations, and pieces of a certain length can considerably slow down the cycle (for nearly all applications).
- The external coil can cause inconvenience during manual spraying.
