HORN: DAH High Feed Milling System


High Chip Volume with High-Feed Milling

Paul Horn GmbH is pleased to present a new development for high-feed milling. The DAH82 and DAH84 systems from Horn represent a new generation of products for this milling process. The precision-sintered insert has eight usable cutting edges, resulting in a low cost per edge and a high level of cost-effectiveness. Despite the negative mounting position, the positive cutting geometry ensures a smooth and soft cut combined with good chip removal. Horn offers the inserts in the substrate SA4B, which is suitable for universal use in various materials. The large radius on the main cutting edge of the indexable insert results in a soft cut, ensures even distribution of the cutting forces and, in turn, extends the tool life. The maximum cutting depths supported are ap = 1.0 mm (0.039″) (DAH82) and ap = 1.5 mm (0.059″) (DAH84).

The DAH82 variant is available as an end mill and screw-in milling cutter in the following diameters: 20 mm (0.787″) (z = 2), 25 mm (0.984″) (z = 3), 32 mm (1.260″) (z = 4), 35 mm (1.378″) (z = 4) and 40 mm (1.575″) (z = 5). As an arbour milling cutter, it is available in diameters of 40 mm (1.575″) (z = 5), 42 mm (1.654″) (z = 5) and 50 mm (1.969″) (z = 6). For diameters in excess of 50 mm (1.969″), the larger DAH84 indexable insert is used. This can be supplied as an arbour milling cutter in the following standard diameters: 50 mm (1.969″) (z = 4), 52 mm (2.047″) (z = 4), 63 mm (2.480″) (z = 5), 66 mm (2.598″) (z = 5), 80 mm (3.150″) (z = 6), 85 mm (3.346″) (z = 6), 100 mm (3.937″) (z = 7) and 125 mm (4.921″) (z = 8). All tool bodies receive a special surface treatment, which results in high strength and hardness, thereby providing long-term protection against abrasive wear from chips.

MAPAL: Hydraulic Chucks with Axial and Radial Adjustment

Hydraulic Clamping Technology with Compensation Technology

The “compensation” chuck is perfectly suited to light clamping tasks with multi-bladed reamers. It builds on hydraulic clamping technology and the radial run-out can be set exactly using three adjustment elements. The radial run-out is corrected using a hex wrench depending on the direction of the error. The setting range is up to 10 μm. Wedges in the chuck align the tool, jamming of the tool is prevented. The system is self-locking, unintentional movement during fine machining is impossible. A fixed ring seals the alignment system. It is therefore low maintenance and not susceptible to dirt.

Radial Tool Length Adjustment

In the area of clamping tools with HSK connection, MAPAL offers hydraulic chucks with radial tool length adjustment.  With this setting method, radial run-out accuracy ≤ 3 μm can be ensured.

HORN: Gear Teeth Deburring | AMB 2020 Technologieforum

Defined Chamfering Deburrs Gear Teeth in Seconds

Paul Horn GmbH has developed a process for precision deburring of gear teeth that represents a further advance in the world of gear production. Although gear teeth can be deburred relatively easily with brushes and discs, higher levels of precision and quality are being demanded, with the result that there is often no longer any scope for undefined chamfers at the tooth edges. So Horn has developed a technology – together with the associated production process – to enable the production of defined chamfers. It can be used, for example, to create a 45-degree chamfer on both sides of a module 1 gear wheel with 25 teeth in less than five seconds. A turn-mill centre with synchronised axes is required for this production process. However, users do not need any special workholding equipment. The solid carbide tools can be clamped in a standard collet, or in shrink-fit or hydraulic chucks.

The process is particularly suitable for machining gears in high volumes. The milling cutters are special tools and have to be individually designed for each gear tooth. Based on the application, Horn engineers will design the appropriate cutting edge geometry for the module, tip diameter and desired chamfer. Horn supplies the process data required for machining together with the cutter. Tool costs are low and quickly pay for themselves thanks to short machining times. The carbide substrate, tool coating and cutting edge geometry are all specially designed for each gear tooth material. As far as the actual machining process is concerned, the material is irrelevant. Chamfers can be milled into various steels, aluminium and plastics within seconds.

MecWash: Aqua-Save System

Wash Water Recycling

The Aqua-Save system from MecWash Systems Limited, UK continuously recovers and re-uses the wash water in parts cleaning systems so the need for disposal is significantly reduced. Water quality is maintained throughout production ensuring that parts exit the system in a clean condition, without contamination with oily residues. The only effluent resulting from the Aqua-Save system is a concentrated waste, consisting of the oils, emulsions and soluble waste washed from dirty components, which represents typically less than 5% of the total water volume.

The Aqua-Save system can be added to any aqueous wash system to maintain solution cleanliness and washing performance, to reduce machine downtime, to minimise effluent disposal and to save money.


  • Removal of free and emulsified oils from the wash and rinse solutions
  • Continuous recovery and re-use of wash and rinse water
  • Significant water, energy, labour and chemical cost savings
  • Environmentally friendly, substantial reduction in waste disposal
  • Maintains continuous production and eliminates system downtime
  • Maintains solution quality and wash performance
  • Compact system, requiring minimal floor space
  • Fully automatic operation with PLC control
  • Can be fitted to all aqueous parts washing systems
  • Media- and chemical-free treatment system – no chemical additives or filter membranes required
  • Enclosed system
