Heavy machining

Innovative solutions for machining large componen

Seco offers a wide range of tools and expert solutions for secure and productive machining of large forgings and heavy castings.

These tools are optimised and engineered with the latest technology to provide large working depths, long overhangs, reliable and durable insert life, dedicated chip breaking and high material removal rates. They are highly stable and excel in handling extreme surface conditions. Our range of Duratomic® grades, which incorporates special coatings manipulated at the atomic level, provide tough and strong performance across all common workpiece materials. These proprietary grades also offer high insert life, making them an ideal solution for applications requiring long times in a cut. We also offer dedicated grades to maximise performance with low cutting speeds in demanding applications, as well as range expansions developed in response to the increased demand for large components made of superalloys, such as Inconel. 
Our standard programme includes, 
Wide range of ISO inserts for super heavy roughing and finishing.
Large shank toolholders in both metric and inch dimensions 
Railway wheel, axle  & related component solutions
Railway wheel re-turning solutions (RWRT) 
Modern and traditional heavy milling cutters.
A complete range of threading solutions, etc.

Shank sizes: 32x32, 40x40, 50x50 mm, (1.25“x1.25“, 1.5“x1.5“, 2“x2“)

Apart from the standard solutions mentioned above, Seco offers custom designed products to meet the needs of various industry segments 

• Pipe and plate scarfing solutions
• Bar peeling inserts and cassettes for peeling heads
• Chamfer milling (strip edge milling) of pipes (I profile, X profile)
• Parting off tubes and shafts (large slitting cutters)
• Pipe beveling and chamfering.
• Crank shaft milling for marine and locomotive engines
• Rail milling (sliding rail, slip rail bearing plate) and track milling
• Gear milling, hobbing, gashing and rotary screw milling.
• Chamfer mills, counter sunk mills and form mills.

Pipe Scarfing Solutions

Seco offers both internal and external scarfing solutions for different materials,
including carbon steels, alloyed steels, stainless steels, hardened steels and
super alloys.

EXTERNAL SCARFING

Negative inserts: SNMX15/19/25, SNMA25
Toolholders and inserts in 3 geometries, Unique “Vulcano” geometry
Tube diameter range: 8-300 mm
Positive inserts: SDUX19/25, For precision, high-speed scarfing for soft materials

INTERNAL SCARFING 

Ring scarfing inserts: Tube diameter range: 12-400 m
Eg: SR8-R46 (Scarfing ring with insert size 8 and working radius 45.6mm)
Tangential scarfing inserts: Single- & double-sided inserts; diameter range: 6-60 mm
Eg: ST1-X2-R40 (Tangential scarfing insert, double sided with working radius 40mm)

BAR PEELING INSERTS (ON REQUEST)

Bar peeling is a method used to remove surface oxide scale, mill scale,
surface cracks, and other imperfections from hot-rolled and forged bar and
tubes. The size of a blank can vary from 4 mm to over 400 mm in diameter. Bar
peeling is also applied to thick-walled tubes. Many bar peeling inserts are also
used for finish turning by virtue of its small approach angle (peel turning).
Seco offers different types of inserts and tools for bar peeling applications,
including LNMX38/40/47, RNGM38, RNMX38/50, TNGX15/33,
TNMX15/49 and TNGX15/33.
