kg] or more,” said Pete Beyer, director of product strategy and development. “Both the Kennametal and Sandvik Coromant ISO standard connections are taper face contact systems with higher retention force than the 50 taper tools. The result is that the modular connections produce a joint that is twice as stiff and a more rigid connection. The difference in cost is signifi cant, thousands of dollars for proprietary tools and hundreds of dollars for modular tools. In addition both modular tool connections were designed for turning ap- plications, whereas CAT 50 was originally a mill- ing connection that was modifi ed for turning,” said Beyer.

For oil and gas industry parts, the V Series is able to take larger cuts because of its stiffness and rigidity. “Higher metal removal rates that are possible with the V Series are especially valuable for machining some of the more diffi cult-to-ma- chine oil industry parts,” said Nelson. Some oil
and gas industry parts involve Inconel inlays inside steel parts which are much more diffi cult to machine and fi nish,” said Nelson. Developed for the job-shop market, the V Series machines also feature the hydrostatic ram found on its bigger brother VTC Series machines. The VTC Series is a 75–267-hp (55.9–149.3 kW) vertical turning machine line with table size from 1 to 8 m and load capacity for the largest oil fi eld parts, Blowout Preventers (BOP) for example. The V Series is a 50–100-hp (37–74.6-kW) machine line that meets the needs of job shops.
Diversifi cation Leads Shops To Develop Own Products
In the last couple of years, the key to business survival has been diversifi ca- tion, according to Milton Ramirez, product technical specialist turning, Haas Automation Inc. (Oxnard, CA): “It’s no mystery that the oil fi eld market has been slow, to say the least, and therefore isn’t generating enough work to keep shops busy. Some of our customers have become job shops and some of them have invented their own products and put them in the market. The great part of being a CNC supplier such as Haas is the versatility that our machines offer. As long as the work envelope allows room enough to fi t a part or fi xture there are no limits to what our customers can do with the machines.”
