Hard part turning with CB7105 and CB7115

Hard part turning is usually a finishing or semi-finishing process with high dimensional accuracy and surface quality requirements.

Sandvik Coromant's new grades CB7105 and CB7115 break new ground in hard part turning. The new grades are based on the newest generation Cubic Boron Nitride (CBN) material. This material enhances crater wear resistance and fracture resistance at high cutting speeds in case hardened and induction hardened material.

Dormer Pramet product tour traverses planes, trains and more

Brian Norris, president of The Americas for Dormer Pramet, spent a few minutes during IMTS 2018 to guide Cutting Tool Engineering Publisher Dennis Spaeth through a number of product highlights from Precision Twist Drill, Union Butterfield, Dormer and Pramet.

Among the highlights:

BIDEMICS all the buzz at NTK Cutting Tools

During a brief interview at IMTS 2018, Steve Howard, marketing and engineering manager for NTK Cutting Tools, discussed the significance of the company's patented BIDEMICS material, calling it "the first real improvement in ceramics in 20 or 30 years."

Chatting with Cutting Tool Engineering Publisher Dennis Spaeth, Howard said BIDEMICS makes it possible to increase cutting speeds in heat-resistant alloys by 17 times over carbide. The new composite material reportedly is capable of running at 1,600 sfm to 1,700 sfm.

Walter Cut MX Grooving Inserts

The Walter Cut MX grooving inserts deliver high levels of flatness and surface quality with their tangentially-mounted arrangement in the G3011/G3021 holders. Four cutting edges per insert multiply user productivity and, if one cutting edge breaks, the other cutting edges remain usable.

M4303 and M4310 Milling Grades

Dormer Pramet's latest milling grades - M4303 and M4310 - provide durability and reliability in semifinishing and finishing applications.

Pramet T8010 Grade

The Pramet T8010 is suitable for continuous precision threading of steels, stainless steel, cast iron and superalloys. It further extends our assortment in this application area and supports the universal grade T8030.

GC4330 and GC4340 Insert Grades

Cutting tool and tooling systems specialist Sandvik Coromant is launching GC4330 and GC4340, two new insert grades for steel milling. With the development of advanced production technologies, such as a new substrate, Inveio coating and an improved post-treatment technology, the new grades provide great opportunities to substantially increase tool life and process security compared to the previous generation of grades, GC4230 and GC4240, which will now be superseded.

CB7105 and CB7115 Grades

Sandvik Coromant is set to release two new grades for interrupted hard-part turning operations: CB7125 and CB7135. Available in October 2018, the grades will complete the company’s offer for hard-part turning, complementing the existing CB7105 and CB7115 grades.

A60 and AG60 Inserts

Walter has introduced the new A60 and AG60 inserts for small to medium pitch threads. Just like the existing MX geometries (CF5 and GD8 for grooving and parting, RF5 for grooving and copy turning), the new MX geometries A60/AG60 provide long tool life, fine surface quality and process reliability. The inserts have four cutting edges.

Cermet WEP10 Indexable Turning Inserts

The new Cermet WEP10 indexable turning inserts from Walter deliver long tool life and high productivity. Their fine-grain titanium carbide substrate with Ni/Co binder produces a stable cutting edge. Combined with an extremely hard TiCN outer layer, this grade provides multiple advantages during finishing operations when compared to carbide inserts.
