Introduction

This document presents technical information about new inserts "SE... .L.." designed for milling cutters S438...13. It includes specifications, material grades, recommended applications, machining parameters, and availability.

Insert Specifications

The inserts are identified by codes such as SEKT 13T3AZFN .L44, SEKT 13T3AZEN .L44, SEKT 13T3AZEN .L54, SEKT 13T3AZTN .L55, SEKW 13T3AZTN .L51, and SEKX 1305 AGSR .Z52. Key dimensions include length (l), diameter (d), thickness (s), corner radius (r), and angles (a°). For example, SEKT 13T3AZFN .L44 has l=10.20 mm, d=13.4 mm, s=3.97 mm, r=4.1 mm.

Material Grades and Coatings

The inserts are available in both uncoated cemented carbide (CERMET) and coated carbide grades. The document lists various grades with codes such as N3105, F1040, T518M, T533, F7010, F8115, and others. These grades correspond to different toughness and hardness levels suitable for various materials.

Recommended Applications

The inserts are recommended for machining a wide range of materials classified by ISO and DIN standards:

• P (Steel): Non-alloy, low alloy, and high alloy steels
• M (Stainless Steel): Martensitic, austenitic, and duplex stainless steels
• K (Cast Iron): Grey, spheroidal graphite, and malleable cast irons
• N (Non-ferrous): Aluminium alloys, copper and its alloys
• S (Heat Resistant Alloys): High temperature alloys including titanium and its alloys
• H (Hardened Materials): Hardened steels

Machining Parameters

Parameters are provided for cutting speed (Vc in m/min), feed per tooth (fz in mm), and depth of cut (ap in mm) for different materials and machining conditions (finishing, medium, roughing). For example:

• Cutting speeds range from 20 to 500 m/min depending on material and insert grade.
• Feed per tooth varies from 0.08 mm to 0.19 mm depending on material hardness and machining type.
• Depth of cut recommendations vary with insert type and feed rate, e.g., for SEKX 1305 .Z52 inserts, max depth is 2 mm for high feed and 6 mm for standard feed.

Formulas for calculating spindle speed (n), feed per revolution (fn), and feed speed (Vf) are included:

• n = (Vc * 1000) / (π * Diameter)
• fn = fz * number of teeth
• Vf = fz * number of teeth * n

Insert Availability and Ordering

Insert availability is indicated as "In Stock" or "On Request". The document provides article codes and price list references for ordering.

Additional Notes

• Lubrication: Parameters are given for both with and without coolant supply.
• High feed machining requires specific insert grades and limits on depth of cut.
• The document includes contact information for SAU S.p.A. and its Modena subsidiary for technical support and orders.
