GC3225 and GC3210 – two new grades covering all cast iron turning operations

Sandvik Coromant has introduced two new grades for machining cast iron. GC3225 and GC3210 form a new insert grade chain covering all cast iron turning operations for both grey and nodular cast iron materials.

GC3225 is a first choice grade for the cast iron turning application area. It is designed to provide secure and trouble-free machining even in the most difficult conditions.

GC3210 is a grade with high flank wear resistance suitable for turning in all cast iron materials, in good to average machining conditions. It enhances reliability and productivity in intermittent cuts, high cutting speeds, wet or dry machining, machined surface or light cast skin.

To provide the edge-line security and wear resistance necessary to optimize performance, GC3225 and GC3210 feature a CVD coating combined with a fine-grained hard substrate. Additionally, their innovative design utilizes optimized micro-geometries to facilitate light cutting action, hence reducing cutting forces and improving tool life.

The results of tests conducted at customers have shown remarkable results. GC3225 has more to give when other inserts reach the end of their life. By using the insert in machining of nodular cast iron it was possible to increase tool life by 70% compared to a competitor grade. GC3210 has been tested in the machining of differential case covers with some outstanding results. After changing to GC3210 instead of a competitor grade, it was possible to increase tool life by 38%.

Sandvik Coromant support for automotive sector embraces extensive machining solutions for transmission shafts

Range of tools and high-performance grades address challenges to deliver improved productivity, security and tool life in transmission shaft machining

Transmission shaft machining solutions include soft stage turning with GC4325 and GC4315 high-performance turning grades

The Sandvik Coromant portfolio of automotive component manufacturing solutions offers a selection of tools and insert grades designed to optimize the machining of transmission shafts.

Beginning with soft stage steel turning, high-performance GC4325 and GC4315 insert grades for internal and external operations offer superior levels of wear resistance, the ability to withstand high cutting temperatures and cutting edges that stay in shape for long times in cut.

Moving to hard part turning, CBN inserts are the first choice for turning high quality steel surfaces in the hardness range 58-65 HRc. CBN inserts from Sandvik Coromant have wiper options optimized for specific applications: WH (wiper HPT) generates low cutting forces for best surface integrity, while WG (wiper general) permits higher feed capacity.

The CoroCut® 1-2 grooving programme offers a number of benefits to those machining transmission shafts. For instance, patented spring clamping delivers high rigidity and clamping force accuracy, while both over- and under high precision coolant is available and easily connected via plug and play adaptors. What’s more, CoroCut 1-2 is now available in GC4325 high performance grade for steel.

Clearly, as a transmission shaft, these complex components demand numerous gear and spline milling operations. Among the tools ideal for addressing this challenge is CoroMill 176, an innovative indexable insert cutter for productive gear wheel machining that is designed for gears in the module range 4 to 10. Also, deployed widely for transmission shaft applications are the CoroMill 172 disc cutter for milling high-quality gear profiles and, similarly, CoroMill 171 for small gear modules. The latter features inserts with two cutting edges, while the same cutter body can hold inserts for different gear profiles.

Other gear and spline profiles on transmission shafts can be tackled using InvoMilling™, the unique Sandvik Coromant approach to milling spur and helical gears using indexable insert cutters, along with CoroMill 161 and 162. Using this single tool set on multi-task machines or five-axis machining centres it is possible to create many different profiles by simply changing the CNC program instead of changing the tool.

Applitec – New 2015-2017 catalogue

The new Applitec catalogue has been completely revised, both in the design and presentation of the items. The many new features offered by Applitec, a company at the cutting edge of technology, to its dealership network and customers are now given a perfect showcase.


In total, 9 product ranges are presented in the new 2015-2017 catalogue. It offers 3 more ranges than the old catalogue.

TOP-Watch – Chapter 1
This complements the TOP-Line range. The TOP-Watch programme is constantly evolving, and developing in collaboration with customers, watchmaking manufactures and watchmaking subcontractors. The specific geometries and coatings of the TOP-Watch range enabling machining of very small parts (D < 0.05 mm) made from the new materials used in watchmaking. TOP-Watch is a major range on the Swiss market.

TRIO-Line – Chapter 2
The TRIO-Line range is a set of tool holders and 3-cut inserts, based on a Y teeth seat concept, which guarantees rigidity and positioning with one-screw clamping.
The TX geometry of TRIO-Line is a set of groove inserts for circlips, as per standards DIN6799 and DIN471.

MICRO-Line – Chapter 8
The dynamic range of hard metal tools with Applitec cylindrical tails. A mirror polish finish, more precise straightness and concentricity than the standard mean that micro-mills, micro-drills, centring devices and milling cutters mounted on MICRO-Line are particularly appreciated in very high-precision micro-milling. MICRO-Line has opened up the way for Applitec into the micro-mechanics sector.

There are several new items supplementing the company’s other product ranges:

ECO-Line – Chapter 3
The high-quality economic range from Applitec.

ISO-Line – Chapter 4
Complementing the Applitec tool holders and inserts, offering a host of cutting geometries and grades. All the items have had their references redesignated based on the standard.

CUT-Line – Chapter 5
Excellence in precision sectioning. Tool holders with perfect seating, for optimum clamping of the insert, with solutions that can cut to diameters of 65 mm.

MODU-Line – Chapter 6
Nine pages of the new catalogue are devoted to base supports and insert holders for Tornos machines. Four of which for SwissNano, and one for Swiss ST26

TOOLING-Line – Chapter 7
A complementary set for MICRO-Line, including knurl holders and left and right-handed MD knurls, D 8.00 to 20.00 mm.

CIRCO-Line – Chapter 9
Extra-fine, fine, coarse and special teeth, for the Applitec hard metal circular milling cutters programme. From Ø 8 mm to Ø 160 mm, with front or rear-clamped mill holding chucks.
