42 MoldMaking Technology —— JANUARY 2016 Products Runout Adjustment System Boosts Collet Holder Accuracy NT Tool's HDZ collet holders feature the company's R Zero runout adjustment system, which uses a four-point mechanism to reduce runout at the tooltip to as low as 0-2 microns. This reduced runout is said to provide better surface roughness and invariant hole diameters than standard collet holders, making it well-suited for smooth finishing with ball end mills or reamers. Setup of the adjustment system is designed to be fast and simple, requir- ing only a spanner to tighten the collet and a wrench to adjust runout of the screws. The adjustment ring can be rotated, allowing runout to be adjusted from virtually any angle. HDZ holders use the company's 12-degree-taper FDC collets, which can grip the cutting tool more evenly than 16-degree ER collets, increasing gripping force and reducing slippage. Metal-sealed, coolant-compatible FDC collets also work without sealing rings, further decreasing downtime for routine setup and maintenance. HDZ holders are available in HSK, CAT (standard and two-face contact), BT (standard and two-face contact), and UTS shank styles. Standard collets cover a chucking range of 0.020"-0.866" (0.5-22.0 mm) in diameter, and custom sizes are readily available. The R Zero system is also available for the company's CTZ holders for large diameters ranging to 1.25" (42 mm) and PHZ-S slim hydraulic chucks for machining in tight spaces.

The oven features 52 kW installed in nickel- chrome wire coils supported by a stainless steel frame. A heat-resisting alloy recirculating blower is powered by a 7-hp motor with a V-belt drive and pro- vides upward airflow to the oven. Workspace dimensions are 30" x 48" x 30". Featuring 7"-thick insulated walls with stainless steel covers, the oven was specially built with inert atmosphere construction consisting of a continu- ously welded outer shell, high-temperature door gasket, sealed heater terminal boxes, inert atmosphere inlet and inert atmosphere outlet. Onboard controls include a motor-operated vertical lift door and a four-point strip chart recorder. The Grieve Corp. / 847-546-8225 / grievecorp.com Coating Suited for Roughing Steel, Hardened Alloys Ti-Coating's Alox SN2 PVD coating for indexable and solid carbide tooling is formulated to provide excellent machining characteristics and to extend tool life for a variety of applications, including turning, threading and milling. The aluminum-titanium-nitride-based coating is well-suited for roughing steel and hardened alloys, including castings. It also provides high oxidation resistance. Ti-Coating / 800-262-5166 / ticoating.com Metal 3D Printing Systems Available for Range of Part Sizes Sciaky's lineup of electron beam additive manufacturing (EBAM) systems include options for medium, large and extra-large part applications, covering parts ranging in size from 203 mm (8") to 5.79 m (19 ft.) in length. Gross deposi- tion rates range from 3.18 to 9.07 kg (7 to 20 lbs) of metal per hour. The technology utilizes wire feedstock, which is available in materials such as titanium, tantalum, niobium, tungsten, molybdenum, Inconel, aluminum, stainless steels, nickel alloys and more. Plus, with a dual wirefeed option, users can combine two different metal alloys into a single melt pool to create "custom alloy" parts or ingots. The mixture ratio of the two materials also can be changed to create "graded" parts or structures. Sciaky Inc. / 708-594-3800 / sciaky.com
