Machining

Using a Tormach 1100 CNC mill, ProvenCut demonstrates Recipe 502, a Fusion 360 adaptive roughing strategy run at 12.2 m/min. (40 sfm) and 0.033 mm/tooth (0.0013 ipt) with a 15.875 mm (0.625") axial DOC (ap) and 0.508 mm (0.02") radial DOC (ae). The demonstration shows a standard four-flute carbide endmill machining 8620 alloy steel hardened to 55 HRC.

The new Walter Helitronic Raptor from United Grinding Group is a flexible, cost-effective tool grinding machine. Created for the grinding and re-sharpening of rotationally symmetrical tools for the metal and wood industries, the new Helitronic Raptor offers both automation-ready flexibility and an economical, universal design.

The DC160 carbide drill features exceptional positioning accuracy.

Glebar Co. delivered a solution for grinding deodorant balls while reducing cycle times and improving throughput. Glebar developed ball grinding for the golf ball industry in the 1960s using centerless grinding fundamentals. The process was adapted to grind deodorant balls and other spherical or cylindrically shaped components. Glebar machines can grind most hard-to-turn materials such as carbon fiber, fiberglass and polypropylene.

A promotion from Blaser Swisslube, Goshen, New York, challenged U.S. manufacturers to test a Blaser metalworking fluid or to share a user experience to raise funds for the National Robotics League (NRL). The 2019 year-end offer raised $2,000 for the workforce development program.

New linear motors and well proven hydrostatic guides in the 6S and 6L grinding machine series open up new potential. Higher speeds, various detailed improvements and optimized ease of maintenance result in shorter cycle times, maximized quality and cost savings. The expanded modular concept for the table assemblies makes the platform 6 grinding machines more flexible and adaptable.

Guards on grinding machines are particularly important for ensuring operator safety. Grinding wheels seldom burst, but when they do, there is a great risk of serious injury to the machine operator. Recent studies suggest, however, that the enclosures commonly used in gear grinding machines, for example, could be overdesigned at present. Investigations conducted by the VDW (Verein Deutscher Werkzeugmaschinenfabriken – German Machine Tool Builders' Association) and the Institute of Machine Tools and Factory Management (IWF) at TU Berlin reveal that it is possible to use safety guards which are up to 70% thinner, depending on the width of the grinding wheel. These findings are leading to changes in ISO standardization.

Walter has launched the new Xtra·tec XT M5008, an indexable high-feed milling cutter in the diameter range of 5/8–2½ in. (16–66 mm) that permits high feed per tooth at low axial depths of cut. Application areas range from pocketing, grooving and surface machining.

Talking ultrafine filtration of water-soluble, fully synthetic coolants, emulsions or oils contaminated by sludge or chips - the use of a suitable filter system in industrial metalworking, such as tool grinding, turning and milling, is an important parameter for success. This is because ultrafine filtration plays a key role in ensuring that the machining process produces high quality, is sustainable and economical, and keeps the wear on the installed coolant system components low. With the new UBF vacuum belt filter, filter manufacturer Vomat is presenting a high-performance system that filters grinding residues, of metals and nonferrous alloys, from a wide variety of lubricants and coolants

Tungaloy is expanding its DoFeed line of high-feed milling cutters to include AH3225 grade inserts. DoFeed is a high-feed milling cutter series with a close-pitched insert alignment, addressing various application needs where an efficient removal of large stock is required.
