X line production cell as a turnkey system
09. January 2023
KADIA recently made a name for itself with a very innovative development.
A leading manufacturer of mobile hydraulic components for forklifts, construction equipment and similar vehicles was looking for a new solution for honing the spool bores in valve bodies.
The accuracy of the honed bore determines the match clearance to the spool, which in turn controls the flow of hydraulic oil. Consequently, the diameter, straightness, roundness, and surface finish of the bores are key factors in determining the internal leakage of the fluid. The tolerances to be achieved are in the range of 1-2 µm.
KADIA has developed a truly unique solution for the manufacturer: three standard X line honing machines, combined into a single production cell. Each X line handles the machining of one bore diameter with pre-honing, finish honing, measuring and brush deburring. The workpiece is transported from machine to machine automatically via a robot. An infeed conveyor with part recognition and buffer function as well as a main control station featuring a central controller and process monitoring complete the turnkey system.
All quality requirements are clearly outperformed, and the capability parameters are achieved without any problems. Above all, the diameter deviations are within a very tight tolerance range. This reduces the number of spool class sizes significantly. The clearance becomes more consistent, and the pairing of spool and bore is more reliable. Compared with the previous system, there has been an enormous leap in productivity: cycle times have been more than halved and output has therefore more than doubled.
In addition, an intelligent fixture design eliminates set-up times during variant changes. Thanks to all these advantages, the X line production cell gives its user a clear competitive edge.
A recent video on YouTube shows the X line production cell in action.

This is how kinematics and machining work during honing
Whenever there is a need to improve the functional sliding, guiding or sealing properties of contact surfaces in bores, all roads lead to honing.
In the case of high-precision parts, the achieved dimensional, geometrical and surface tolerances are less than 1 µm. But how exactly does this demanding process work? What are its characteristics?
What is typical to honing is, above all, the simultaneous overlaying of...MORE
V line – new flexible honing machine
02. May 2021
If the range of workpieces is large and quantities vary, a variable machining unit is needed. KADIA developed the V line for this constellation. The Vario honing machine is a flexible configurable honing solution with 2 or 3 honing stations.
The machine fits in line between the 2-spindle U line universal machine and the R line, which is equipped with up to 6 spindles, and it takes on their strengths: The structure is similar to the U line, very compact, with an integrated...MORE
EC Brush - new crankshaft deburring machine
13. October 2018
Before crankshafts are finished, careful deburring is a must. In most cases, this is done with the help of a robot that guides the workpieces to a tool console. The programming is extensive, the robot must be taught anew for each workpiece variant.
The EC Brush deburring machine from KADIA is an easy-to-use, cost-effective standard solution. It impresses with high productivity and low support and maintenance costs. The machine has five programmable axes and is flexibly...MORE

In keeping with the motto "Digitization increases process reliability", KADIA presented a field-proven Industry 4.0 application at the AMB exhibition in Stuttgart: A 2-spindle U line honing machine communicated with XM honing tools via a RFID tag. Important benefits are plausibility checks and the storage of information for later data analysis.
XM honing tools are equipped with read and writeable RFID data memories in which tool-specific identification and geometry data is...MORE
XC Honing Tools – Two-piece precision tools
02. May 2021
The XC honing tools from KADIA are based on a two-piece construction consisting of tool holder and tool body - C therefore stands for "Combined". A clamping unit allows both tool parts to be connected and disconnected in seconds. The XC tool system convinces with its high flexibility and high accuracy. The available diameters range from 4 mm to 40 mm.
The XC tools have been specially designed for the ultra-precise LH2 honing spindles with 17 mm clamping diameter. Like their...MORE
New Hybrid Deburr-Robot-Cell - high-pressure jet deburring included
02. May 2021
The mechanical processing of engine blocks leaves many burrs on surfaces, shoulders, bores or threads. Thorough deburring of all edges is therefore required for finishing and assembly. KADIA uses brush deburring for this task whenever possible.
However, with bores < 6 mm in diameter, the limit for brushing has been reached, so that another technology becomes necessary: high-pressure jet deburring. In a new Hybrid Deburr-Robot-Cell, KADIA now integrates both technologies...MORE

Stand-alone Plunge Measuring Station for Match Honing
20. October 2021
Match honing, the ultimate challenge in honing, is used whenever an exact match between piston and bore is required. First, the plunger is measured pneumatically, then the target diameter of the bore-to-be-honed is calculated individually. The basis for this is a defined match clearance of usually only a few µm. Normally, measurements and plunger handling are carried out fully automatically in a robot loading cell. If complex automation does not pay off, for example in the...MORE
Honing of BEV pinion gears with sophisticated design
09. April 2022
Honing of transmission gears has been one of KADIA's core competencies for many years. A honed bore with high dimensional accuracy and optimum surface finish reduces friction and promotes powertrain efficiency. This is particularly true for battery electric vehicles (BEV). System-related high standards of smooth operation are also required here.
Many of the BEV transmissions, some of which are very compact, contain stepped pinion gears with a sophisticated design. For...MORE
