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 case of smaller quantities, the plunger measuring station developed by KADIA can be used as a stand-alone system. This is designed as a compact auxiliary solution and is suitable, for example, for operation with the 2-spindle universal honing machine U line, one of the most successful machines in the KADIA program. This is designed as a compact auxiliary solution and is ideally suited for operation with 2-spindle or 3-spindle honing machines, in particular the U line, V line and T line series.
The honing machine in combination with the plunger measuring station is a cost-effective and easy-to-operate solution for the highest quality requirements. The operator inserts the plunger manually, and at the push of a button starts the measuring process and the transfer of the values to the HMC100 control system. The honing machine then machines the bore of the workpiece, which is also inserted manually, exactly to the calculated target diameter. The typical match clearance between bore and piston that can be realized in this process is in the range of 1 to 10 µm with tolerances of 1 to 3 µm.

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

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

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
