Software extensions and additions

All Krob sorting machines are equipped with a CUTS central control unit with a touch panel. The panel is designed for easy and intuitive operation so that even the staff with the lowest level of training can handle the basic function of the machine. All machine control and settings are carried out using the CUTS unit. All CUTS units also record and display inspection results in the form of numerical values compared to the calibrated value and in the form of detailed graphs, from which it is possible to visually determine, for example, the ratio of the magnitude of the real defect to total noise (Signal to Noise). For each batch checked, the CUTS unit displays statistics of the number of balls sorted and the settings for defectometric methods. Statistics can be printed using a connected printer or stored in the memory for later printing.

Possible extensions of the basic software


The WebBS system is designed for online monitoring of Ball Scanners from one or more observation points (dispatching centers) and at the same time data is collected enabling subsequent viewing of the history of individual monitoring points. Thus, the operator (shift manager, etc.) is visually in control of all Ball Scanners with the help of a web browser, and at the same time can look back at the progress of inspection of a certain batch.

  • Possibility of online monitoring of statistical data (PC, Smart TV, tablet, Smart phone)
  • quick overview of sorting from the comfort of your office / home
  • up-to-date information on all Ball Scanners in the form of a table
  • filters that allow you to filter the necessary information (eg. by batch name, ball size, time period, etc.)
  • auxiliary search interface
  • data can be exported, which is useful for creating statistics, reports, logs, annual reports, etc.
  • possibility to monitor entered batches / outputs of machines

Customer’s spherocone roller dimensions

Are you introducing an inspection of a non-standard ball size to your operation and you cannot find this dimension in the basic menu of your Ball Scanner? Contact us and we can discuss the upgrade of your software and the design of new dimensions of the spherocone rollers.

The Width Different (WD) mode

All Krob Ball Scanners are equipped with software modules for ball inspection in STanDard (STD) and AeroSpace (AS) mode, which can satisfy the vast majority of even the most demanding customers (including applications for the aerospace industry). If your inspection quality requirements are even higher than that, then the Ball Scanner can be equipped with a Width Different (WD) inspection software module, which can use the smallest possible ECT core diameter and maximize the number of defectometric passes of the ball under the cores.

Cross Probe

Thanks to the new technology, the classic arrangement of two ferrite cores of the ECT differential probe has now been replaced by a cross arrangement of four ferrite cores. The cross arrangement allows the overall diameter of the ECT probe core to be reduced while maintaining the effective width of the probe. This makes it possible to achieve greater sensitivity of the ECT probes while maintaining the same length of time ball inspection.

Sorting statistics

The sorting statistics graphically show the quality distribution of the sorted balls in the batch and also retrospectively, which allows the comparison of production batches with each other. All important data, such as set ECT / EVT / EOT sorting parameters, counter status and more, are stored in the history in the CU-TS. Statistics can either be displayed directly on the CU-TS, printed on a connected printer, or saved to the SD card in the “history” and then downloaded to a PC in PDF format via the web interface.

Statistics are therefore a suitable tool for long-term monitoring of ball quality.

The printer

Each Ball Scanner allows you to print using a connected external printer. The statistics of the inspected batch can be printed from the display of the CUTS unit or from a file stored in memory. Contact us for the correct type of printer.


Pre-assembled tables for Ball Scanners with their specific constructional design make the work easier for operators and allow attaching of additional devices that interact with Ball Scanners (Hardness Tester, Diameter Sorter, Packers).

The tables are assembled from duralumin construction profiles, they can also be delivered disassembled, which is advantageous especially for air transport. The tables are available in three height variants:

Table height (H) Table for Ball Scanner Table for Ball Scanners with Safety Flap (SF)
40´´ (1016 mm) K 102 000 K 102 010
45´´ (1143 mm) K 102 001 K 102 011
50´´ (1270 mm) K 102 002 K 102 012

The SF tables are designed for Ball Scanners fitted with Safety Flap (SF). It differs by the reduced height of the storage plates of the boxes for inspected balls. The Safety Flap (SP) is used with Ball Scanners for small diameter balls. This device prevents the ball from falling into the OK outlet in the event of a sudden power failure or similar event.
An additional desk can be ordered for each table for placing boxes with sorted balls, etc. This additional platform is available in two versions – one without overlapping the ground plan dimensions of the table and with a one-sided overlap, which can be used for locating other accessories. The board is grounded (earthed) and provided with a conductive surface. In combination with boxes made of ESD material (boxes for balls – set) the board dissipates any electrostatic charge.

Input and output container stands

Different types of input and output stands, according to the customer’s needs, are made of duralumin  construction profiles and are used to place input and output containers at the required height, thus ensuring smooth entry of the balls to the Ball Scanner for inspection and a smooth output of inspected balls into the prepared container.
The stands can be adapted to the dimensions of the container at customer’s request.
We also supply stands equipped with roller tracks for easy handling and transport of heavy packaging.
Example of the usage of the stands and configuration options can be found here.

Boxes for inspected balls - set

Practical special accessories for the so-called dry machines for sorted balls of small diameters. Boxes made of antistatic material are placed on a stainless-steel sheet, which is grounded (earthed) and thus dissipates any possible electrostatic charge.

Each box has a transparent cover made of Perspex. This eliminates the risk that any BAD ball might fall among the OK balls. It also prevents dirt from getting onto the inspected balls.

A shock absorber (of different sizes depending on the diameter of the balls being sorted) is attached to each housing, which not only reduces the drop height of the ball, but also distributes the balls equally to all sides. This way the box is filled evenly, and the operator does not have to adjust as often. These special accessories include sensors that monitor the filling of individual boxes. When the box is filled, the machine stops automatically.

  • Boxes made of ESD material
  • stainless steel grounded sheet that dissipates electrostatic charge
  • sensors that monitor the filling of the boxes
  • transparent perspex covers to prevent bad balls from falling among good ones and prevents dirt getting in
