Ultra-fine filtration for maximum quality at minimum operating cost
24. July 2023
The honing process requires thorough cooling, flushing and lubrication of the machining area. Only then can the high quality requirements for honed bores be achieved in a reliable process. Prerequisite is that honing oil arrives at the point of machining at the correct temperature and optimally cleaned.
KADIA meets these requirements with the HFF coolant lubricant filter system designed specifically for this purpose. HFF stands for Honing Fine Filtration system. The unit operates with several filter towers based on the principle known as gap filtration. The honing oil is pressed through a large number of filter discs and the dirt particles are filtered out at the edges. The nominal filter rating is 5 to 7 µm, well below the usual values of >20 µm in band filter systems with filter fleece.
The filter towers are cleaned by backflushing fully automatically without any interruption to the honing process. The service life of the filters is up to three years, depending on the material and dirt load. The dirt particles are discharged into a 60-liter sludge drum via an integrated scraper conveyor with a low residual moisture content and virtually unmixed. This guarantees favorable disposal costs.
Thanks to its continuously high filtration quality, the HFF not only optimally supports the honing process, but also extends the service life of the honing oil many times over, thus saving money. In addition, clean honing oil ensures a long service life for honing tools, fixtures and machine components, thereby reducing maintenance costs over the entire life cycle of the honing machine.
The HFF systems have been specially developed and tested for our KADIOL 50 and KADIOL 90 honing oils and are suitable for all KADIA honing machines with up to three honing spindles.

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

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...MORE

Stand-alone Plunge Measuring Station for Match Honing
15. 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
