manufacturers. Speedcenter machines have the power, torque, speed, and acceleration characteristics to machine the most diversified materials from steel and cast iron and from aluminum alloys to titanium alloys.
Speedcenter machines maintain the “T” structure with the table moving on the X axis and the column on the Z axis. Three models are available starting from the 1250 × 1250 mm pallet with X-Y-Z travels of 3000, 2000, and 2300 mm up to 2000 × 25000-mm pallet with 4600, 3000, and 3200 X-Y-Z travels. The rotating table features hydrostatic support and the rotating Z axis is driven by a preloaded double rack-and- pinion system to ensure backlash-free positioning. Choice of CNC control includes Siemens 840D sl, Fanuc 30i-A, or Heidenhain iTNC 530 NC.
Titanium Challenges Machine Stiffness
Difficult-to-machine workpieces, typically the newest titani- ums, Inconels, high-strength stainless alloys, and other alloys
have forced an even greater design discipline on machine builders and suppliers of cutting tools, toolholders, coolant systems, and CNCs. All of them taken together are necessary for successful machining results. “The crux of the matter for optimum heavy-metal machining lies in the ability of the ma- chining system to perform low-frequency machining without chatter, hold tools tightly with heavy-duty tool tapers, increase machine stiffness construction, and deliver the power neces- sary,” says Scott Walker, president, Mitsui Seiki (USA) Inc. (Franklin Lakes, NJ). According to Walker, the volume of titanium to be used in aircraft in 2012 is projected to be 100 million lb (45,359 t). Remarkably, this represents only 35% of total titanium consumption, and demand is growing, says Walker. Mitsui Seiki’s HS6A-5X five-axis HMC with 1300 × 1200 × 1200 X- Y-Z and two 1000-mm square pallet tables has demonstrated its effectiveness in machining moderately complex titanium workpieces up to 1000-mm long.
I HAVE PROBES ON MY MACHINE; I DON’T NEED A PRESETTER
Misconception #8
The Truth Is: A probe may be an effective way to verify tool lengths between cuts, but it is not the most efficient way to set your tools. A “guess-and-check” process for making adjustments wastes valuable cutting time. A Speroni MAGIS Tool Presetter can verify runout, measure length, diameter, radius, and other geometries using measuring icons, and it can also inspect tools for wear. Spend less time adjusting and more time cutting.
The notch-free nut design of our Mega Micro Chuck prevents vibration at high speeds for superior balance and concentricity. It not only eliminates whistling noise and coolant splattering, but also assures increased strength of the nut itself. The super slim taper design of the body offers added strength for micro end milling, and reduces interference in long reach applications.
