IN-FEED

RADIAL IN-FEED

TECHNICAL INFORMATION Thread

Metal removed on both sides of the insert simultaneously. The most commonly used method for thread production.

MODIFIED FLANK IN-FEED

Less wear of the trailing edge and better surface finish on corresponding flank.

ALTERNATING FLANK IN-FEED

Both edges are being fully utilised which means longer insert life.

FLANK IN-FEED

More easily formed chip and better heat dissipation.

TECHNICAL INFORMATION

THREADING All threads up to 4,5 ° helix angle can be manufactured with HORN standard threading inserts. No special anvils will be necessary.

SEATINGSThe seating design of tooling type MINI as well as Supermini® guarantee the accurate center height of these tools. In spite of this, always check center height because a difference may cause problems, especially when machining small diameters.

TORQUE OF SCREWS The following torque specifications are required for screws of MINI inserts. e do not recommend the use of anti-seize pastes.

REMOVAL OF CHIPSPlease choose inserts with smaller cutting widths, which helps aid chip evacuation and flow out ofthe bore.To avoid chip packing, use proper machining techniques, such as grooving by steps.

COOLANTUse a filtered coolant for transporting the chips out and for cooling the insert itself. A coolant pressure of 5 bar min. is recommended.

CARBIDE GRADES

UNCOATED GRADES

MG12 - a universal grade with good wear resistance. Used at low or medium cutting speeds for machining steel, cast iron and non ferrous materials

COATED GRADES

a very popular grade TiN coated used to low or medium cutting speeds. Also recommanded for machining stainless steel or exotic alloyed materials

TN35 -

TI25 - a TiCN coated grade with high abrasion resistance. Recommended for machining steel and non ferrous materials at medium cutting speeds

TF45 - a TiAlN coated grade. This coating has a very high temperature stability and high hardness and is only used for special applications.

TH35 - new standard grade - extreme temperature stability with high hardness and very good coefficient of friction
