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.

FEATURES & BENEFITS

  • 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

HORN: Bevel Gear Cutting Solutions | AMB 2020 Technologieforum

Cost-effective even for Small Batch Production

Paul Horn GmbH is expanding its range of gear cutting products. Horn’s new tool system for milling bevel gear teeth allows the complete machining of bevel gears on universal turn-mill centres. The system was created in cooperation with machine manufacturer INDEX and means that users no longer need any special machines to manufacture gears of this kind. It also allows all functional surfaces to be produced together with the gear teeth in one clamping. This enables high component precision, short lead-times, a very cost-efficient process and short machining times as a result of controlled machining cycles. With a universal turn-mill centre from INDEX, components with bevel gear teeth can be efficiently and flexibly manufactured, including in small quantities. This also makes the process attractive to small and medium-sized companies that would previously have bought in gears or had them manufactured externally.

For the process, Horn relies on its S276 and S279 double-edged indexable inserts, which are screwed on tangentially. This makes it possible to achieve a stable insert seat, which is particularly important during form milling. The tool does not have to be remeasured after the inserts have been turned around or changed because the inserts are precision-ground on the circumference. The milling body can be equipped to allow for different numbers of teeth and outer diameters when cutting gears. The process of developing the complete system (cycle, tool and clamping) called for a great deal of expertise on the part of both the machine manufacturer and the tool manufacturer. To implement the process, various types of INDEX machine with a “bevel gear hobbing” cycle are required. Horn offers the milling cutter bodies with the HSK-T40 and HSK-T63 interfaces. The profiles of the inserts are module-dependent and precision-ground.

HORN: DS System for Titanium & Titanium Alloys

Efficient machining of Titanium

Horn has optimized its DS milling system to enable productive, cost-effective machining of titanium and titanium alloys. The optimizations are made possible by the newly developed substrate IG3I.  By combining the novel carbide grade with a new coating, Horn has been able to increase tool life significantly.

The new substrate demonstrates homogeneous wear.  A sharp micro-geometry on the cutting edges, positive rake angles, large clearance angles and polished flutes prevent strain hardening of the workpiece and built-up edges on the rake faces when machining titanium. Variable helix angles and different tooth pitches ensure a quiet, low-vibration milling process. Despite the sharp cutting edges, the new coating demonstrates very high layer adhesion, thus ensuring good cutting edge stability.  Thanks to its high temperature resistance, the coating serves as a heat shield and reduces the amount of heat transferred to the carbide.

In future, the IG3I substrate will replace the previous substrate TSTK, which is already known on the market for its high performance. The end mills are available in diameters from 2 mm to 20 mm as standard, with four or five flutes. The effective length is two or three times the diameter. DS titanium milling cutters were developed based on the tried-and-tested solid carbide milling cutters in the DS system, which for years have been used to machine soft and hardened steels, chromium-nickel steels and super alloys as well as copper, aluminium, plastics and fiber-reinforced plastics.
