High-feed mill range extended

The TungForce-Feed line of indexable, small diameter, high-feed milling cutters has been expanded by Tungaloy to include R2 inserts that feature a corner radius of 2 mm.

Available in diameters of 8, 10, 12 and 16 mm, the TungForce-Feed line is pitched as an economic profiling solution for the mould and die industry when compared with conventional solid end mills and indexable tools of similar size.
During the creation of a CAM program for the high-feed machining of complex 3D profiles in typical mould-making applications, it is common to use a theoretical corner radius for programming the insert radius. However, this method leaves excessive stock on the workpiece after machining, adding processes.
Looking to generate the ideal platform for subsequent finishing processes, many job shops are using solid-carbide square-end mills with large radii during roughing. The latest R2 insert requires no programming for the theoretical corner radius, as its 2 mm corner radius leaves no uncut material on the machined surface. This concept ensures that the TungForce-Feed series makes a good replacement for costly solid-carbide end mills.
Featuring an insert design that is 10% thicker than competitor products, the TungForce-Feed line is built to perform at higher machining parameters by withstanding fracture forces. The insert design incorporates a positive inclination angle for smooth chip evacuation which further reduces cutting forces by controlling chip formation, especially when shoulder and slot machining.
Designed for face and shoulder milling, as well as helical interpolation and ramping, the close insert pitch makes the TungForce-Feed line a good option for all milling applications. The series has been designed with a small entry angle for chatter stability that improves efficiency and tool life, even when machining in long-reach areas, says Tungaloy.

Multi-function tools from Horn

Horn’s Supermini precision tooling system has been enhanced by the introduction of a variant with newly developed HP geometry, allowing higher infeed rates and other cutting parameters. The geometry also enables multi-functional use on a lathe across a range of operations, including drilling, boring, face turning and skimming.

In terms of capability, holes from 3 to 7 mm in diameter may be drilled into solid material using Supermini HP tools without a chip breaker. While the performance data cannot compete with normal drills, the system is a practical solution if the number of cutter locations in a machine is limited. With the single-edged version, various hole diameters can be produced using a single tool.
Horn’s Supermini HP offers the option of immediately boring an inner contour after drilling without having to change the tool. An accurate 90° shoulder can be achieved at the base of the hole, while the wiper geometry produces excellent surface quality, even at high feed rates, says Horn.
Tools can also be provided with a chip breaker, which are recommended for turning applications. Here, the slightly twisted flute helps to remove chips efficiently from the machining zone, while the EG35 coating allows machining of both standard and stainless steels.
As well as HP geometry, Horn has developed a tool holder for the Supermini type 105, whereby clamping is achieved using a tensioning wedge on the face rather than on the circumference, as was previously the case. The tool is held in place with more force, which in turn makes the entire system more rigid. Furthermore, the design results in a higher level of repeatability when changing the tool and permits more compact construction.

£300k investment at Corbetts

Corbetts the Galvanizers, one of the UK’s oldest hot-dip galvanising specialists is celebrating a major birthday in 2020 by pressing the button on a £300,000 investment drive.

Employing 105 people at its Telford facility, the company will turn 160 this year, and has a range of events scheduled to help it mark the major anniversary, including the installation of new flux and acid tanks that will release capacity and speed up the galvanising process. The management team is now setting its sights on a 7% increase in volumes which, if achieved, will generate an additional £1m of revenue.

Orbis cutters from Quickgrind

The ‘Infinite Possibilities’ portfolio has been expanded by Quickgrind with the arrival of the Orbis lollipop cutter range.

Across its business, Quickgrind is focused on the supply of products tailored to the demands of end users, hence the Infinite Possibilities branding. An example is the newly developed Orbis series of lollipop end-milling cutters. Non-standard sizes and geometries are available to manufacturers on very short delivery times and at “near-standard” prices, says the company.
Developed for the five-axis machining of intricate components, the solid-carbide Orbis range enables access to difficult-to-reach features and surfaces. Furthermore, the Orbis series allows manufacturers to use a single tool to follow challenging tool paths and component forms.
Orbis cutters are available with two, three, four, six or eight flutes, with a complete variety of lollipop and shank diameters, overall lengths and a wide range of reduced neck diameters. In addition, the spherical ball profile and unconventional geometry enable the cutters to excel in terms of tool life, machining speeds and feeds, and surface finish quality, says the company.
The tools are suitable for the fine finishing of irregular or uneven surfaces, as well as the daunting prospect of tube machining. This capability is credit to the carbide composition of the end mills and the UK-designed tool geometries that minimise vibration, even when reaching difficult-to-access surfaces.
Contributing further to the reduction in vibration and cutting forces, as well as improvements in tool life and productivity, are three geometry styles for alternate material types.
