Economical Reaming In Cast Iron And Steel In High Quantities

Economical reaming In Cast Iron And Steel In High Quantities

MAPAL is launching a new, particularly economical system of replaceable head reamers – the Press-to-Size-Reamer (PSR) – for customers who manufacture in large series. Thanks to the new development, the costs per bore are reduced massively.

The solid carbide replaceable heads are specifically adapted to individual diameters and geometries. The replaceable head system for the diameter range 10 to 25 mm consists of a robust holder, the solid carbide replaceable head and a coolant distribution element. The connection is highly accurate. This means that the heads can be changed by the customer’s employee on site without any adjustment or logistics effort, a big plus in terms of cost-effectiveness. The replaceable head is merely exchanged and disposed of. There is no provision for reconditioning the replaceable heads.

By eliminating the logistics cycle, the new replaceable head system significantly improves the economic efficiency of reaming operations in large-scale production. This effect is even reinforced by the fact that, in contrast to carbide-tipped reaming tools, the solid carbide replaceable heads can be designed with a CVD coating – with correspondingly positive effects on tool life.

A Drill For All Materials

A Drill for All Materials

It’s said that life is a marathon, not a sprint. For automotive manufacturers, longer lasting tooling solutions are integral to more profitable production—but, often, manufacturers see little reason to change their existing tool set-up. In this article, James Thorpe, global product manager at Sandvik Coromant, explains why the benefits of longer-lasting tools shouldn’t be underestimated, particularly for reducing costs-per-part or increasing overall output.

A Drill for All Materials

Unpredictable tool life is one of the biggest threats in mass automotive production, particularly as its operations are so highly-automated and use some of the world’s most advanced robotics and automation systems. Downtime is time-consuming, disrupts production and is also expensive, so it goes without saying that tool failures should be avoided at all costs. 

In some instances, manufacturers set the tool change interval to less than the maximum tool life. This approach is normally preferred because material variations in automotive components are minimal. It follows that the tool changes should be predictable, and safer, than trying to extend the tool life to manufacture a few more components. 

Multi-material Drilling

For Sandvik Coromant’s specialists, the key to longer tool life is not limited to the amount of time a tool spends in use, but also the drill design itself. This approach led to the development of the CoroDrill 860 with enhanced -GM geometry, a new design solid carbide drill that’s optimized for a wide range of materials and applications, across all industry sectors. 

For the CoroDrill 860-GM, Sandvik Coromant applied its machine tooling and metal cutting expertise to develop a new grade, a unique fine-grained carbide substrate known as X1BM. The fine-grained carbide is imbued with increased hardness while maintaining toughness.

Furthermore, the drill is tip-coated with a multi-layer physical vapor deposition (PVD) thin film coating. This is key to improving the drill’s productivity and delivering a consistent tool life across a variety of materials. The result is a tool with excellent stability, machining security and improved tool life when machining cast iron, steel, stainless steel, hardened steels and non-ferrous metals.

Assessing Tool Life

A better way to assess tool life is by measuring the amount of material removed. To aid productivity, the CoroDrill 860-GM has an innovative, polished flute design that improves the evacuation of chips and yields greater hole quality. This also helps to reduce heat build-up in the tool, and further benefits are high core strength and reduced cutting forces while drilling.

The 860-GM forms part of Sandvik Coromant’s CoroDrill range of solid carbide drills. They are designed not only for optimized performance but also versatility, which means they can be deployed in a variety of applications and materials across multiple industries.

This includes use with the following material groups: ISO-P, the largest material group in metal cutting that ranges from unalloyed to high-alloyed material; ISO-M that includes difficult-to-cut stainless steels, austenitic steels and duplex steels; ISO-K grey, nodular and compacted graphite cast iron; ISO-H steels with a Rockwell hardness of between 45-65 HRc; and ISO-N for softer, non-ferrous materials such as aluminium, copper and brass. 

Advanced Geometry

As mentioned, the CoroDrill 860-GM has an enhanced design, but what exactly does this entail? Much of this relates to the design of the drill itself that includes an advanced optimized point and flute geometry, reinforced core and corner chamfers, edge preparation to remove cutting edge micro defects, and a double margin to enhance drilling stability. The drill’s point is also designed with refined clearance angles and improved surface quality. 

Overall, these design features stabilise the drill, reduce entry and exit burr and improve the hole tolerance, finish and straightness. The drill also gives stable wear progression and delivers excellent hole accuracy.

Iscar Expands Range Of Solid Carbide Milling Heads For The Aerospace Industry

Iscar Expands Range Of Solid Carbide Milling Heads For The Aerospace Industry

Iscar Expands Range Of Solid Carbide Milling Heads For The Aerospace Industry with new interchangeable models featuring a 100° point angle. The solid carbide milling heads are suitable for chamfering, countersinking, and spot drilling applications.

The Iscar new interchangeable heads are available in four diametre sizes: 9.525mm, 12.7mm, 15.875mm, and 19.05mm. They are designed mainly for countersink holes for head cap screws according to ISO 5856, DIN EN 4072, IS 15437 standards; and for rivets according to MIL-STD-40007. The Iscar heads can also be applied for machining countersink holes for general-use 100 deg flat countersunk head machine screws, in accordance with ANSI B18.6.3-1972 standard. Most aircraft countersunk screws require a 100° angle countersink.

Hoffmann: Garant MasterSteel PickPocket

Hoffmann: Garant MasterSteel PickPocket

Hoffmann’s Garant MasterSteel PickPocket is suitable for milling slots and pockets, as well as for side milling, ramping and helical milling. It has three cutting edges and a drill tip recessed towards the milling shaft.

The three cutting edges enable very large flutes in comparison with a four-cutter design, allowing for more swarf removal.

The positive rake of the solid carbide mill makes it very free-cutting and suited for machining fragile and thin-walled components. The tool is available for a diameter of 5.7 to 20 mm in the standard length and also with a longer neck.
