Machining

Advanced programming strategies and simulation can lead to the production of better composite parts, according to CGTech.

The nine-edged milling systems M911, M913 and M928 are stocked in cutting widths from 1.5 mm (0.059") to 3 mm (0.118") as standard. The maximum milling depth is 3.5 mm (0.138") (M911), 4.5 mm (0.177") (M913) and 6.5 mm (0.256") (M928). The inserts are available with different coatings to suit the material to be machined. Due to its mass, the solid carbide tool shank ensures vibration damping during milling. All variants of the tool shanks are equipped with an internal coolant supply.

The modular system has a selection of tool holders for turrets and other tool carrier interfaces based on common machine types. The matching grooving tool holders with integral coolant supply allow height adjustment of the cassettes and their mounting in the normal or overhead position, on the left or right of the holder.

As with other tool systems, high-performance reaming systems are also subject to demanding requirements. In addition to high process reliability, long tool life and low tool costs, modern reaming tools must fulfil further criteria. These include, among other things, the modularity of the tools. While machining with an HSS reamer is partially limited in this respect, modern reaming systems can be improved by replaceable heads with carbide inserts, modular tool lengths and various adjustment options. These include, for example, µ-accurate adjustment of concentricity and runout. Precise concentricity of the reaming inserts is the path to success. In practice, this should be within 5 µm.

Star Cutter has added a Lasertec precision laser cutting machine to its portfolio of machining equipment at its Tool Reconditioning Center.

The new grade is Walter's response to the upwards trend towards milling steel with difficult machining properties and wear-resistant stainless steel, such as found in applications in the energy and aviation industries. WSM35G meets the most stringent requirement for process reliability, which is highly valued in the automotive sector, and is also suitable for general mechanical engineering applications.

Global engineering technologies company Renishaw brings its latest end-to-end solutions for additive manufacturing to RAPID + TCT 2023 in Chicago.

TCB now offers AH6225 grade inserts. This latest physical vapor deposition (PVD) coated grade features a high-hardness titanium-rich PVD coating, combined with a tough dedicated carbide substrate. Extremely reliable and versatile insert grade, AH6225 allows TCB to efficiently cut bores in all material groups, including steel, stainless steel, and exotic materials.

Providing exceptional reliability and increased tool life in steel, the new AH3225 insert grade consists of a unique nano-multilayer coating featuring three distinctive characteristics for improved resistance to built-up edge, wear, and delamination, combined with a dedicated tough carbide substrate. AH8015 is another PVD grade, consisting of extremely hard PVD coating combined with a tough carbide substrate. The grade demonstrates excellent tool life stability in cast iron and heat-resistant superalloys.
