Coronavirus: KADIA processes high-precision parts for ventilators


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.

New Hybrid Deburr-Robot-Cell - high-pressure jet deburring included

01. September 2020

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...



22. October 2020

For the machining of very long bores with diameters < 20 mm, for a long time 3-spindle honing machines were the unsurpassed state of the art. Many KADIA customers all over the world have proven these machines. However, the common process sequence with rough, intermediate and finish honing requires a relatively complex machine concept with high space requirements at corresponding costs.

For KADIA this was one reason to develop a new compact high-performance machine for...


EMO 2019: KADIA with largest exhibition booth so far

20. November 2019

This year's EMO, from 16th to 21st September, attracted around 117,000 trade visitors to Hannover. Despite the negative economic forecasts, the general mood at the world's leading trade fair for metal processing was good - also at KADIA.

With 169m², the booth was bigger than ever before. The KADIA sales team conducted more than 100 technical discussions, which dealt with concrete project inquiries. KADIA presented a wide range of products, including the new X line honing...


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...


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...


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...


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...

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...
