Cutting Tools & Tooling

Manufacturer seeks cost-effective thread shafts with shorter lead times

When using indexable inserts, employ fine adjustment cartridges made for the 21st century.

The latest Pramet range includes three variants of a 16-edged ONMX insert for depths of cut up to 0.157" (4mm). The standard geometries include the F for light operations, M for versatile use, and R for rough cuts in a variety of materials. Additionally, the 8-edged ONMX-W is a specific wiper insert for high-quality surface finish with large cutters and high feed rate.

Horn has revised the clamping of the S224 type indexable insert for use in Swiss-type lathes. In order not to have to remove the holder for indexing or changing the insert, the Horn engineers relocated the clamping screw to the side. Clamping now takes place via a camshaft. This allows the insert to be clamped quickly at either side of the holder without having to remove it.

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.

With the new versions of the T2711 and T2712 thread milling cutters, Walter offers an indexable insert solution for small blind-hole and through-hole threads (≤ 2.5 × DN) in dimensions of M16, M18 and UNC3/4. It can be used in almost any material.

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.

Die flipping hoist rings are available in both inch and metric dimensions as a standard or Lift-Check™ style that features a proprietary hex head bolt with Go / No-Go identification. The rings are CE Certified and constructed of alloy steel with a black oxide body and zinc plated (gold) shackle. All the rings are made in the USA, magnetic particle inspected, conform to ASME B30.26 and MIL-STD-209, and feature a 5:1 strength factor.

The H-Carb Series 77 end mills specialize in deep axial trochoidal and high-speed machining applications and are offered in various lengths of cut. The specially designed core and flute design improve rigidity and chip flow while reducing deflection. The seven-flute design allows for superior finishes at higher speed and feed rates versus 5 and 6 flute tools.

The product expansion includes best-in-class features and advanced technology for metal cutting applications. The launch includes eight products that expand on and support existing platforms in delivering superior performance across multiple applications as well as address common machining challenges
