S SKT4. LM24 Many different systems are used in industry for measuring material hardness. The table below compares three of the most common systems. Please see material cross reference list on page 6.
Cutting data is given on the ordering pages for If the material being machined differs in hardness the recommended first choice grade in combina- from those values, the recommended cutting tion with the hardness HB in the table. Reduced hardness Increased hardness. Example: You are using an 80 mm diameter cutter. Find the cutter size in the left column, and cutting speed in the top row and read the spindle RPM at the intersection: revolutions per minute.
Use the largest bar size and smallest possible bar overhang to provide maxi- mum stability. Tolerances Insert thickness. Insert shape 5.

Moderate cutting speeds. Forged and cast First choice! Low cutting speeds. Weak compo- nent clamping. Continuous cuts. Tool life Mins. Feed Note! Cutting data on insert dispensers are based on a tool life of 15 minutes and will remain the same with the values taken from this diagram.
Result: Decrease the feed with 0. Medium and roughing machining ap x fn cutting depth x feed. Productivity improvements with Wiper inserts Wiper inserts are innovative high-productivity inserts for semi-finish and finish turning. Thanks to a sub- tle change to the insert nose radius the feed rates can be doubled without changing the surface finish.

Sandvik Coromant has released the version of its CoroKey guide, which helps manufacturers quickly and easily identify the first choice tool combination and appropriate cutting data for specific applications. The page guide details applications and cutting tool solutions in a variety of areas, including turning, milling and drilling. It also offers practical tips and information on modular tooling and insert grades. The guide now includes information on calculating important figures, such as metal removal rates for common machining operations. It also features frequently used cutting data formulas with illustrations and definitions of terms used. Each section of the CoroKey guide begins with an overview on selection of inserts, grades and tooling for a specific type of application. This is followed by guidance on modular tooling, tool safety, maintenance and wear and troubleshooting.
