Our assortment of cutting tools for heavy machining applications includes both milling and turning products. Here, we focus on removing the first layer of material from large-scale forgings, castings and rollings.
Typical customers are major, high-volume manufacturers, material suppliers and sub-contractors providing pre-machined blanks. These operations require highly reliable tools capable of working in very tough conditions.
Our significant experience means we have a broad customer base, with Dormer Pramet tools machining crank shafts on cruise liners to components for the largest wind power generators!
We offer dedicated geometries for chip control, grades that provide reliable tool life and longevity, with a rapid response for tailor-made tooling.
milling range includes face milling cutters, 90° shoulder milling cutters,
helical milling cutters, chamfer milling cutters and special milling cutters.
Our main priorities in this application are high metal removal rates and
reliability of the cutting edge.
For heavy turning we offer a selection of positive and negative insert geometries and corresponding tool holders designed for removing the first uneven layer of material. Eccentricity of the workpiece is very common, and our tools are manufactured to provide mechanical stability. Indexable inserts need to cope with very abrasive workpiece surfaces and be both wear resistant and tough to withstand the interrupted cut. These products can achieve high metal removal rates up to 1500kg/hour.
We offer a specific assortment for bar
diameter reduction and removal of metallurgical defects from forged
and rolled blanks.
This includes inserts in different shapes, geometries and grades for steels, stainless steels, and other
difficult-to-machine materials. In addition, we provide clamping systems and
cassettes to meet a variety of customer needs, such as process reliability,
surface quality and durability of the cutting edge. Important elements within
this application are high productivity, dimensional accuracy, and
excellent surface quality.
Tube machining applications
addition, we supply a comprehensive set of solutions for various operations performed in the tube manufacturing
our long-term focus in this field, we are one of only a handful of global
companies to offer a complete program of inserts for scarfing - the process of removing the weld deposit created
during tube production. Our assortment covers external scarfing
inserts and tool holders,
as well as rings for internal operations in all common tube
Tools for processing tubes and pipes
with large diameters:
produce a wide assortment of special
products for producers of large diameter
This includes tools used for strip chamfer milling operations in preparation for the
longitudinal welding process, as well as products for the final bevelling operation
of the tube face surface, with angles according to customer needs.
within this portfolio are custom-made products for special thread profiles, according to API and GOST
specification, for both internal and external tube and coupling threads.
holders and indexable inserts are optimized to meet the high accuracy
expectation desired for these types of products and applications.
