“The latest generation of CoroMill 316 adds a longer cutting length to its list of attributes, delivering even greater flexibility for machine shops,” said Tiziana Pro, product manager solid end mills at Sandvik Coromant. “Specific operations to benefit includes those that demand higher axial depth, up to 1.2 x Dc, as well as where high stability and vibration suppression are required. In particular, the combination of the modular Coromant EH system and CoroMill 316 provides a number of solutions for all types of machines and user challenges.”

Manufacturers should choose Coromant EH as the preferred rotating modular interface for applications up to 32mm (1.256in) in diameter. Integrated machine adaptors with EH coupling are recommended for small interfaces where gauge line and swing diameter are critical (BT30, SK40, HSK40/50/63, ER, DTH), as well as different shank types in long overhang applications up to 35mm (1.38in) diameter.

Sumitomo Electric Industries, Ltd. (head office: Chuo-ku, Osaka, President: Osamu Inoue, hereafter "our company") has developed and launched the tool grade AC4125K, for interrupted machining of cast iron, for sale as of December 28, 2023. Cast iron is used in the automotive industry among many other fields, where gray cast iron*1 is used for parts such as engine blocks and brake discs where sliding is required, while ductile cast iron*2 is used for parts such as differential cases and carrier cases where strength is required. In recent years, the ratio of high-strength ductile cast iron (FCD600 and above), with high strength and poor machinability, has been increasing, in order to reduce thickness and weight in consideration of the global environment. In addition, parts machining is increasingly subjected to harsh cutting environments such as interrupted machining of complex shapes and rough machining where cast surface is machined as it is, leading to tool life fluctuation due to cutting edge chipping becoming an issue. In response to these issues, our company has developed the coated grade for cast iron turning AC4125K. Although priced the same as our company's conventional tools, it helps reduce machining costs by lowering tool usage and tool change frequency through stable and longer tool life. 1. Features Our 1st recommended grade for interrupted machining of cast iron. Through the use of AbsotechTM, our proprietary CVD*3 coating technology, to provide excellent chipping resistance by maximizing compressive stress to realize stable and longer tool life for roughing of components such as differential cases and carrier cases. In addition, the use of a gold exterior makes it easy to identify used corners, contributing to easier tool management. 2. Lineup Insert: Total of 244 Cat. Nos. (December 28, 2023: 128 Cat. Nos. for sale; February 2024: 116 Cat. Nos. for sale) 3. Sales Plan 90 million JPY in the first year, 340 million JPY/year after 3 years 4. Price Priced the same as our company's conventional tools (Standard Product) CNMG120408N-GZ: 980 JPY (excluding tax) *1Gray cast iron: Cast iron is an alloy primarily composed of carbon (C) and silicon (Si), with C content of 2.1% or more. Gray cast iron is a type of cast iron that appears gray on the fracture surface because carbon is more present in the form of graphite than in the form of cementite. *2Ductile cast iron: A type of cast iron containing somewhat more carbon and silicon than gray iron, with the graphite becoming spherical due to the addition of magnesium and/or cerium. *3CVD (chemical vapour deposition): One of the coating deposition methods, which uses gas reaction to form a thin coating film. Raw material gas containing the ingredients of the target coating is supplied to a heated substrate material in a reaction chamber, forming the coating through chemical reaction in the gas phase or on the substrate surface.

Solid Round Tools are purpose-designed to support workflow, efficiency and productivity, with each cutter positioned within three product categories: versatile, optimised and customised. Versatile solutions are performance-oriented tools based on maximising flexibility and cost efficiency for the customer, while optimised solutions comprise a unique line of refined tools for specific needs where extreme efficiency, reliability and durability are paramount. Customised solutions are designed individually to meet the highest performance demands.

CoroMill 316 is part of the extensive Solid Rounds Tools offer from Sandvik Coromant, which today includes more than 10,000 standard products to cover all applications within the areas of solid carbide drilling, milling, tapping, reaming and threading.

CoroMill 316 is suitable for all general milling operations, including high-feed face milling, slot milling, helical interpolation, shoulder milling, profile milling and chamfer milling. The exchangeable heads allow users to easily and accurately switch between various operations, creating end mills with optimised radius variation, teeth frequency, geometry and grade. Beyond steel and stainless steel, the tools can also be used successfully on ISO K (cast iron) and ISO S (heat resistant super alloys) materials.

The new CoroMill 316 generation of exchangeable-head milling cutters from Sandvik Coromant enhances the company’s established Solid Round Tools portfolio by bringing higher levels of versatility and productivity to machining operations in ISO P (steel) and ISO M (stainless steel) materials. Further benefits include high reliability in almost all applications, along with enhanced tool life and a silent machining process.
