Boehlerit Expands 3D Milling System

Boehlerit Expands 3D Milling System

Paul Horn GmbH presents the Boehlerit 3D milling system expansion for the tool and mould making industry. The ISO 00P, RHOMBItec, BALLtec and TORROtec systems cover all relevant machining operations for the 3D milling market segment.

The ISO 00P is a universal tool system for general mechanical engineering and mould making. As the inserts are mounted in a neutral position in the tool holder, they ensure a high level of contour accuracy. Despite the neutral position, the edge geometry enables a soft cut to be achieved. With the RHOMBItec system, Boehlerit is presenting a universal finishing tool for all standard materials and applications. The indexable inserts demonstrate high manufacturing precision and long tool life. The axial and radial wiper geometry ensures high productivity, outstanding surface quality and vibration-free finishing, even at high depths of cut.

The BALLtec and TORROtec milling systems are multi-functional tools for achieving high productivity. They allow users to save on tool holders, as the ball nose copying tools are suitable for semi-finishing and finishing. In addition, Boehlerit offers a wide variety of indexable inserts and tool holders. The carbide shank with brazed insert seat ensures excellent vibration damping, resulting in outstanding surface qualities on the workpiece. The use of ultrafine carbides for the inserts ensures high wear resistance combined with high fracture resistance, which increases process reliability. All variants are fitted with an internal coolant supply.

New Solid Carbide Milling Cutters For Tool And Mould Making

New Solid Carbide Milling Cutters For Tool And Mould Making

Under the product name OptiMill-3D, MAPAL is announcing a new high-performance programme of solid carbide milling cutters specially developed for tool and mould making. Along with extremely heat-resistant coatings and special carbide substrates, these tools are characterised in particular by the dimensions and geometries specifically adapted to mould making.

High-feed machining with high material removal rate

Suitable for milling hardened parts with a hardness of 45-66 HRC, with the OptiMill-­3D-HF-Hardened with four or six cutting edges MAPAL is announcing two new high-feed milling cutters for hard machining. So that the tools also work reliably even in difficult application conditions such as an interrupted cut, MAPAL has developed a special face geometry.

The milling cutter with four cutting edges is used above all for roughing as well as for pre-finishing. Due to the fewer number of cutting edges and the related more generous dimensioning of the chip flutes, reliable removal of the chips is ensured. This milling cutter is also the tool of choice for machining with long projection lengths and in deep cavities.

The milling cutter with six cutting edges can be used optimally for roughing and pre-finishing, as well as for finishing flat surfaces with a high feed rate. It produces the best surface finishes and flatness. The equivalent, the OptiMill-3D-HF, with three and four cutting edges is available for soft machining. The dimensions here are matched to the OptiMill-3D-HF-Hardened.

Highly accurate corner radii for maximum precision

The corner radius milling cutter OptiMill-3D-CR-Hardened is used for finishing 3D moulds up to a hardness of 66 HRC. It produces very good, smooth, high-gloss surface finishes with maximum feed rate. Crucial here are the highly accurately manufactured corner radii. The OptiMill-3D-CR-Hardened is available in the diameter range 4-12 mm with different lengths and corner radii.

Efficiency in pre-finishing and finishing on 5-axis machines

The new circular radius milling cutters OptiMill-3D-CS are predominantly used in mould making in deep cavities, for complex free-form shapes as well as for the manufacture of turbine blades and impellers. The special feature of the tools is the optimal geometric combination of radius and form cutter that makes a larger path spacing during pre-finishing and finishing possible. The machining time can be significantly reduced and the quality of the surface finish on the parts significantly improved. For machining deep, difficult-to-access cavities, the OptiMill-3D-CS in droplet shape is the first choice. Large surfaces and surfaces with tool restrictions are machined highly efficiently using the milling cutter in the tapered shape.

Agathon Showcases Its Innovations For Tool And Mould In EMO 2019

Agathon Showcases Its Innovations For Tool And Mould In EMO 2019

At the EMO 2019 Agathon will highlight new developments in the field of machinery and services, as well as solutions and innovations for guiding, centering and quick-change, especially for tool and mould making.

Agathon will be presenting its broad portfolio for tool and machine construction to visitors at the EMO 2019. The company highlights their top products such as the roller guide systems, in particular, for tool and mould making, but also for mechanical engineering and automation.

This porfolio also includes the Mini Fine Centering, which has gained an excellent reputation since its market introduction in the spring of 2018. With the static application of the Mini Fine Centering tool and mould inserts can be backlash-free, easy rolling and thus highly precise centered and they can also be changed extremely fast, without expert knowledge and without tilting.

Mechanical engineers are increasingly enjoying the opportunities for quick change, which is offered by the mini-fine centering. A popular field of application is the quick exchange of clamping tools. Other areas of application for the Mini Fine Centering include precision automation, for example, when gripper tools are positioned. There, the Mini Fine Centering ensures maximum process reliability, it eliminates vibrations and guarantees gentle and precise part removal.

The Mini Fine Centering can now also be used for dynamic applications. In particular, the centering of floating cavities in multi-cavity tools and moulds should offer a broad field of application for the Mini Fine Centering. Thanks to its small footprint, the number of cavities can be increased by up to 30 percent. Since the Mini Fine Centering is not paired, additional bushings of the standard 7989 can be used – in particular for turning tools or automation solutions, this offers new application possibilities.

Furthermore, the new maintenance-free sliding bushing is Agathon’s third spring innovation. It distinguishes itself especially for dry running, whereby the small backlash enables a very precise guidance. The sliding surface of the bushing is designed and structured to achieve a very high performance together with the surface of the pillars, the counter partner from the Agathon range.
