Revised classification system from Seco
Seco has released a new version of its workpiece material classification system (SMG) that makes it easier to understand the complicated interactions between cutting tools and workpiece materials during milling, turning and holemaking operations.
With the improved SMG v2, Seco provides new data as well as simplifies the way in which it organises the content, so that more customers use the classification system as a basis for maximised metalcutting operations and productivity gains.
Seco expanded the SMG to present the latest information on today’s advanced tool materials such as PCN, PCD and ceramics. The company also widened its range of workpiece material classifications for steels, cast irons, non-ferrous materials, super alloys, titanium, plastics, composites and more.
The colour-coordinated groups within the classification system indicate the ISO category for each material type, while a comprehensive cross-reference list indicates where a material may appear in different SMG groups based on how it is processed, e.g., annealed, quenched and tempered for through hardening.
Furthermore, each SMG category includes details on a reference material that the user can refer to in order to determine if the cutting data should be adapted for their specific application.
In terms of how of Seco organises the comprehensive data in SMG v2, the company makes identifying the most appropriate cutting tools and cutting parameters for a particular workpiece material quick and simple by presenting all relevant data in a concise, logical manner.
The company categorises workpiece materials by type, capabilities and characteristics, rather than relative levels of machinability. A simplified cutting-data chart format now runs common across all Seco product catalogues.
Plus, a new data display format makes charts applicable to all tool types.
