Forging billets and re-rolling billets in a wide range of stainless steels, duplex stainless steels and nickel alloys. The billets are 100% ultrasonically and eddy current tested in a fully automated inspection line to ensure the highest quality standards.
Forging billetsSandvik's billets for forging are suitable for producing all types of forged products, such as flanges, discs, rings, valves, forged parts, and axles. Our program of forging billets includes a wide range of stainless steels and high-alloy materials.
Re-rolling billetsBillets for re-rolling of strip, wire, bar, hexagons and profiles, available in square and rectangular sizes. The production route for re-rolling billets is often more simplified than that for forging billets, since in most cases products do not require a dense center. For many of these products, continuous cast material can be used, which contributes to lower raw material costs.

| Precision reamers are designed to slightly enlarge the size of a previously formed hole with a high degree of accuracy that leaves the sides smooth. Youll find the reamer tool you need here for a variety of applications and materials. |
CoroReamer 435 is a multi-application, versatile and high speed reamer, suitable for a wide range of materials. It gives you really close hole tolerances and high-quality surface finish thanks to internal coolant, the cutting edge geometry and extremely unequal spacing of the cutting edges.
Benefits| Spiral flute
| Straight flute
|
Comparison of unequal and extremely unequal flute spacing
Extremely unequal flute spacing means that the divide is not the same for each tooth. As there are no teeth diametrically opposite each other, the reamer produces a hole with improved hole roundness variance.

Advantages
Seal ring grooves are critical features on many oil and gas components, and require close tolerances and a high-quality surface finish. The high component value and complexity make process security essential. Adding to the challenges is the common use of difficult-to-machine materials solid Inconel 718 and cladded Inconel 625.
Machining challenges
Many conventional methods for machining seal ring grooves have poor process security and slow down production. Existing conventional plunging and radial turning tools need to perform roughing and finishing in multiple operations, and they involve high cutting forces with limited tool life. When secure, these processes are slow and costly with no flexibility regarding groove-diameter size.
SpiroGrooving
SpiroGrooving is a new, groundbreaking innovation a simple yet sophisticated manufacturing process of grooves for sealing rings. The method is used with theCoroBore XL systemand utilizes a spirograph tool path to create close-tolerance seal ring grooves in a very secure and productive way.
The tool path consists of tapered, circular ramping where the tool engagement is according to a set ramping-pitch for each revolution. An NC-code generator calculates the SpiroGrooving tool path based on a few input-parameters, such as groove diameter, process pitch and chosen maximum chip thickness. Tool presetting is done in a few simple steps.
This solution is ideal for making seal ring grooves in pre-clad machining of steel and stainless steel. The unique internal coolant solution of CoroBore XL facilitates machining in advanced materials. Roughing and finishing are carried out in the same operation, which significantly reduces machining time and improves productivity.
SpiroGrooving fulfils all the crucial objectives for machining seal ring grooves in the most efficient and reliable way:
SpiroGrooving uses a circular spirograph tool movement in a taper. This reduces chip thickness, enabling light cutting action and increased feed. Parts of the insert cutting edge have an interrupted cutting behaviour, eliminating long chips tangling to the tool and spindle.
Tooling componentsThe tooling is based on state-of-the-art, proven standard concepts, where modularity provides broad groove-application flexibility. Where conventional methods require a new set of tools for every groove type or -size, one SpiroGrooving tool covers a range of diameters, providing flexibility in production and a minimized tool inventory.
The tool for SpiroGrooving is an uncomplicated, clever twin-edge tool with twoV-style inserts based on the well-established CoroBoreXL boring system. This combined with the Coromant Captomodular tooling concept offer a dedicated solution for seal ring groove machining
With the previous conventional radial, multi-edge turning concept for rough and finish operations, the total machining time was two minutes. No diameter flexibility was available and setting was a relatively lengthy procedure.
Switching to SpiroGrooving, the machining time was reduced to 50 seconds. The tool can be used and easily re-set for several other groove applications. The component was moved on in less than half the time with the new method.
