HORN: Supermini System with HSK Interface

Horn is expanding the Supermini tool system with new holder variants. The holder range is specifically aimed at use in modern mill-turn centers. The tool manufacturer is thus reducing the number of interfaces between the insert and spindle compared to conventional chucks. This enables greater precision and higher process reliability. Horn offers the holder system with various machine interfaces, including: HSK-T63, HSK-E40 for Willemin-Macodel, HSK-A40 for Bumotec and HSK-T40 for all other multitasking machines. In all versions, the Supermini insert is located and removed using a face clamping and lifting system. Clamping is achieved not via the lateral surface of the tool, but via a wedge on the end face. This raises the force with which the insert is held, resulting in high rigidity of the overall system.

Boring, profile turning, internal grooving, threading, chamfering, axial grooving, drilling and slotting. The Supermini tool system can be adapted and used for numerous machining operations. The solid carbide insert is for machining bores from 0.2 mm to approximately 10 mm in diameter. Horn developed the tool blank as a teardrop shape, enabling precise contact surfaces in the tool holder. Furthermore, the shape prevents the insert from twisting, leading to a consistently precise tool center height. With long tool overhangs, it reduces deflection and minimizes vibration during the turning process. Depending on the application and the diameter to be machined, Horn offers the insert in three different sizes (types 105, 109 and 110). All variants allow for internal coolant supply directly to the cutting zone. The Horn tool portfolio contains approximately 2,500 different standard variants of the Supermini. In addition, Horn has solved users’ problems with countless customized solutions.

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.

New MAPAL Tool Holders Programme

At a Glance
  • New design concept for chucks with added value
  • Brilliant surface finish and clear handling information
  • Expansion to the entire chuck programme planned
Advantages
  • Corrosion-resistant chucks
  • Self-explanatory, straightforward handling – foolproof
  • Greatest possible stability with optimal usage of resources

Carefully considered Design taps Potential

Not only the appearance of the chucks was revised, above all added value for the customer was to be generated by means of carefully considered industrial design. Why? An ingenious design is not only a visual highlight, it also taps economic and ecological potential. Starting from this point, the product designers prepared, together with those responsible for the products at MAPAL, a new concept that is also based on function and FEM analyses.

The chucks designed according to this concept shine proverbially with a new brilliance. One of the elements in the new concept is the brilliant surface finish. This surface finish, produced by a specially developed polishing method, ensures that the chucks are more resistant to corrosion than in the past.

Easy, Self-explanatory “foolproof” Handling

A further requirement on the new design was so-called “foolproof handling”; that is the easy, self-explanatory handling of the chucks. Controls were to be identifiable as such more quickly with directly understandable handling information. These requirements were addressed, on the one hand, by the blue colour for the controls, such as the actuating screw on a hydraulic chuck and, on the other hand, by internally developed symbols that contain corresponding information, independent of the related language.

Last but not least the shape of the chucks, their weight and use of material were studied and optimised. The new shape addresses the requirements for the greatest possible stability with optimal usage of resources. Even the smallest weight savings on chucks have major effects that become apparent in use over the long term. Among other aspects, the lighter the chuck, the less energy is required during the acceleration and braking of the spindle.

Corporate design creates Recognition

Due to the new corporate design, the complete clamping technology range can be immediately identified as a MAPAL product – with a promise of quality and function.
