New Software Version Cutting Grades for Drill Increase Tool Life The GC4344, GC3334 and GC2334 grades for the CoroDrill 870 are produced with Zertivo, a PVD produc- tion technology developed by Sandvik Coromant. This technology maintains the the properties of the previous technology and is said to improve edge line security, chipping resistance and overall wear resistance properties. Available in various geometries, the latest grades are said to be versatile and cover applications in varied ISO materials, although they are designed for steel, stainless steel and cast iron. According to the company, all grades are designed to deliver specific enhance- ments related to common wear issues in drilling. Designed for the intermediate hole-tolerance range of H9 to H10, the exchangeable-tip drill saves time and reduces cost per hole, the company says. The drills can be tailored to applications through a selection of diameter, length, step or chamfer possibili- ties. The drill is available in a diameter range from 10 to 33 mm (0.394" to 1.299") and a depth capacity from 3 × D to 12 × D. :: Sandvik Coromant Inc. 201-794-5000, Chuck Jaws Fit Master Jaws with Hard-to-Find Pitches A manufacturing upgrade enables Dillon Manufacturing chuck jaws to add serrations of 2 mm × 60 degrees and 2.5 mm × 60 degrees for hard-to-find top jaws, hard jaws and full-grip jaws that fit the corresponding chuck master jaws of the same hard-to-locate pitch. The company says it can now manufacture virtually any serration. Dillon offers a range of jaws including soft jaws, hard jaws, full-grip jaws, collet pad jaws, vise jaws and custom jaws. The standard and cus- tom chuck jaws and collet pads are said to be ideal for high-speed machining, in addition to precision boring, tapping, drilling and finish- ing across many industrial markets. :: Dillon Manufacturing Inc. 800-428-1133 :: 41 PRODUCTS To submit your company's product, contact Lori Beckman at Rotary Transfer Machine Expands Capacity :: Hydromat Inc. 314-432-4644, Hydromat Inc. presents the Eclipse 12-100, a 12-station rotary transfer machine. This platform features multiple tool spindles with one chip management and coolant system. This ductile iron casting is designed for the use of three-axis and four-axis electric servo, quill-type tool spindles. The bar-fed collet version has a workpiece diameter of 65 mm (2.5") and features a maximum length of 180 mm (7") with 127 mm (5") of material outside the collet. An indexing chuck version features a table with vertical chucks capable of rotating workpiec- es 360 degrees. This system is said to be ideal for mid- to high- volume, precision production of irregular-shaped castings and is designed to accommodate families of parts. The machine uses hydraulically actuated, self-centering two- or three-jaw chucks to provide accuracy and part clamping rigidity. The three-axis tool spindles are 55/250 units, referring to the 55-mm front bearing size and a 250-mm stroke at the Z axis. The X-axis stroke is 80 mm and the Y axis is 100 mm. The four-axis module features a flange spindle for mounting a turning head with 30-mm X-axis stroke, or a 160-mm diameter head for 5,000-rpm cutting. The units use HSK 50 toolholders, powered by a FANUC ail T6/12000HV motor. A 20,000 rpm tool spindle is also avail- able. A CNC head features an outside diameter of 160 mm with a radial stroke of 25 mm. The machine features quick-change, preset tool heads for easy change-overs.
