Milling Cutters

The H330 Series is engineered exclusively for high-speed milling of Aluminum applications.

Electric mobility is becoming increasingly important in the automotive industry. The number of electrically powered vehicles produced is increasing. MAPAL already offers a wide range of innovative machining solutions for the manufacture of individual parts and components that are machined.

Imagine burying a roughing tool in a block of Ti-6Al-4V titanium and ripping away more than 1,000 cm3 (61 cubic inches) of material in just one minute. If you’d been at a recent test of Kennametal’s new HARVITM Ultra 8X helical milling cutter, you’d have seen exactly that. Using a 95 mm (3.74 in.) axial depth of cut, 20 mm (0.78 in.) radially, and a feed rate of 423 mm/min. (16.65 ipm), the 80 mm (3.15 in.) diameter HARVI Ultra 8X plowed through this difficult aerospace superalloy for nearly 3 minutes straight without flinching.

The M4258 modular helical milling cutter from Walter, the most recent addition to its M4000 family of high-performance helical milling cutters, brings cost efficiency and excellent process reliability to slot milling, and can be used for ramping, pocket milling, shoulder milling and circular interpolation as well. Versatility also extends to materials, handling ISO material groups P, M, K and S.

Connecting rods are highly stressed engine parts. To take account of downsizing and the reduction of CO2 emissions, connecting rods are also becoming increasingly lighter. This is achieved on the one hand through the use of high-strength and innovative materials, and on the other hand through modern production processes. This also changes the shape of the connecting rods and the variety of shapes increases. MAPAL offers the complete process for machining different types of connecting rods – whether on the transfer line or the machining center, as well as for wet or MQL machining.

In November 2004, when LACH was awarded the German Innovation Prize for a newly developed technology for the cost and time efficient machining of aluminum components with a monoblock diamond cutter »dia-compact«, it was already said, “Nothing is more efficient than this … .” However, there was still something more efficient – as proven by the development of »Cool Injection-Plus», cooling directly via the PCD cutting insert.

The new CSC (Curve Segment Cutting) CurveMax milling cutters from tool manufacturer Inovatools not only reduce processing times for finishing complex free-form surfaces in tool and mold construction, turbine blade production, and complex component geometries in general machine engineering, but also enhance surface quality compared with the full-radius mills previously used for these tasks.

MAPAL has introduced a milling program with pressed, radial ISO indexable inserts, thus completing the portfolio of standard milling tools. Up to now, the company has mainly focused on a milling program with ground, tangential ISO indexable inserts. These are used in particular for special applications, very large stock removal, unstable conditions or disc milling cutters.

As a leader in compression spiral tooling, LMT Onsrud has expanded its product offering on two of its most popular compression tooling lines: the Polaris and Marathon Compressions.

LMT Onsrud is offering its innovative compression tooling technology within its new line of high-speed steel dor-bits.
