Inserts

Ask The Experts: Indexable Inserts

Cutting Tool Engineering's April 2022 issue includes a feature article about double-sided inserts and high-feed indexable insert milling tools that can help reduce production costs. To supplement this report online, CTE will host a webinar at 10 a.m.

CTCP115-P (ISO P15), CTCP125-P (ISO P25), CTC135-P (ISO P35) Insert Grades

Three Insert Grades Optimize Steel Turning

To prevent insert waste and easily detect wear, the gold-colored TiN outer layer of the Dragonskin multilayer CVD Ti(C,N)/Al2O3/TiN coating acts as an indicator. It not only enables users to clearly identify insert wear and index before a breakage, but also prevents sharp cutting edges from going unused and the insert being inadvertently discarded. Plus, a mechanical post-coating treatment produces beneficial residual stress in the coating that results in increased process security, especially important in the large-volume production situations typically associated with turning ISO-P steels.

PCD Turning Inserts

NS chipbreaker features a three-dimensional chipbreaker that is directly engraved on the PCD tip using the latest technology. This allows the generation of short chips during the machining of gummy metals such as aluminum and copper alloys, significantly reducing machine downtime due to chip associated troubles.

TungCut CBN-Tipped Inserts

TungCut CBN-tipped STH inserts provide the solution to these challenges with a completely new turning concept. In the shape of TungCut grooving insert, the new STH inserts perform finish-turning by feeding the insert sideways on the worked surface. Its CBN cutting edge features a unique wiper geometry: the frontal edge features an arc wiper of large radius. This generates superior surface finish in straight-line turning applications, while also allowing increased feed rates of up to 1.5 mm (.060″) per revolution with up to 0.1 mm (.004″) d.o.c.

Tiger·tec Gold Inserts

The primary application of the Tiger·tec Gold inserts is steels with various tensile strengths that can be machined. These indexable inserts are ideal for use in the automotive, energy, and general metalworking industries, where the inserts can significantly help reduce the cost per component. Walter is offering Tiger·tec Gold indexable insert grades with its signature geometries starting with finishing (FP5), medium machining (MP3, MP5, MU5) all the way to roughing (RP7, HU5), etc. along with some other niche geometries for specialist troubleshooting purposes.

Tungaloy small insert lines

Tungaloy going small. Small inserts, outstanding productivity. Featuring the AddDoFeed for maximum speed and efficiency at minimum size, Tung-Tri for small shoulder milling operations with cost-efficient inserts and outstanding chatter stability, TungForce-Rec versatile shoulder milling cutter with unique V-shaped bottom for maximum productivity, AddInternalCut four-edged insert for small internal grooving operations with a minimum diameter of 0.438”, and AddMeisterDrill — the world’s smallest exchangeable head drill series with 0.004” increments.

CBN Grade WBH30

Additional improvement in surface quality and stability can be realized with advanced wiper geometry option. Walter offers the new WBH30 CBN grade in inserts with and without MW wiper geometry, and with a negative T-land chamfer for excellent strength in interrupted cuts.

Guhring's System 222 for grooving and parting-off

Guhring Inc. highlights the features of its System 222 (two cutting edges, 22 mm length) for grooving and parting-off in this brief video. Carbide inserts have chipbreaker and cutting geometries pressed into them during sintering for maximum consistency. Left-hand, right-hand and neutral insert designs provide optimal productivity. Square shank and parting blade toolholders are available with or without coolant through.

The next generation grades in steel turning

With the WPP10G, WPP20G and WPP30G grades, Walter presents the new Tiger·tec® Gold indexable inserts, specially designed for turning operations. The multi-layered, highly textured MT-TiCN Tiger·tec® Gold coating increases tool life by an average of 50%.

DoFeed LNMU0303UER Inserts

The new LNMU0303UER inserts are designed to provide a smaller approach angle than existing LNMU0303ZER inserts when set on the cutter body so that the insert generates thin chips. This chip thinning effect reduces cutting loads, minimizing damage on the cutting edges during machining of exotic materials for longer insert tool life. Also, a small approach angle directs the cutting forces in the axial direction towards the spindle.
