Coronavirus: KADIA processes high-precision parts for ventilators
30. April 2020
Medical technology has always been a central field of application for high-precision honing - this is becoming particularly evident these days.
At the Homburg location, KADIA processes linear ball bushings for voice coil motors on a subcontract basis. These electro-mechanical precision actuators control the flow and pressure of breathing gases (air and oxygen) in intensive care ventilators. A failure of these components would be life threatening for the patient.
The quality requirements of the bearings with a diameter of 5 mm are extremely high; diameter tolerance -0,003 mm, cylindricity < 1 µm and a surface finish of Ra < 0.05 µm ensure almost friction-free movement and outstanding control characteristics – for at least 100 million cycles without replacement. KADIA uses a fully automated multi-operation process with the latest honing technology and custom-made honing tool abrasives.
Due to the sharp increase in demand for ventilators in recent weeks, KADIA has continuously expanded its job honing capacities. Currently the team in Homburg produces up to 2,000 linear ball bushings in three shifts every day.

XC Honing Tools – Two-piece precision tools
26. August 2019
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
RFID tool identification
11. March 2019
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
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
V line – new flexible honing machine
12. June 2018
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

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
