The Super-Precision Quest CHNC turning center is offered with a 27-mm, 5C collet-ready spindle or a 42-mm, 16C collet-ready spindle. The machine is designed for quick job change-over to meet the increasing demands of the medical, aerospace, defense and computer/electronics industries. This design configuration allows the use of top plates and tooling used on thousands of previous-generation CHNC machine installations.

The RS 51 MSY turning center with live tooling, C axis, Y axis and subspindle offers exceptional vibration control, thermal stability and accuracy, the company says. The turning center has a collet-ready spindle that uses a range of the company’s precision workholding devices and is designed to be hard-turning and hard-milling machine that economically produces complex hardened parts in a single setup. All RS Series models (RS 42, RS 51 and RS 65) feature the Eppinger Self Alignment (ESA) top-plate tooling system, allowing highly accurate tool positioning and directing cutting forces to the machine base, the company says.

 With the number of turning centers on the market, matching a machine with the right capabilities for a shop's needs can affect price and performance. Thsi article looks at three levels of turning center capabilities and how each plays out various application specifications.  

In the early 1990s, Mr. Langlois decided to set up a shop specializing in close-tolerance aerospace parts. A friend of his recommended that he consider a colleted-spindle turning machine and suggested that he look into Hardinge lathes. Mr. Langlois purchased a used Hardinge HNC lathe and began making aircraft landing gear bushings.

The SR 200 BB (big bore) multitasking turning center from Hardinge offers a Sure-Grip lever type 250-mm (10") three-jaw chuck as standard equipment. The machine can be configured with many multitasking functions including, live tooling. Y-axis, C-axis and subspindle, needed to machine complex small- to medium-sized

The GS 200 MSY and GS 250 MSY multitasking turning centers offer expanded levels of functionality to address complex parts resulting in increased throughput and reduced cycle time in one setup, according to the company. As standard equipment, these machines include dual wound spindle motors with 30 hp on the main spindle and 20 hp on the subspindle; 10-hp live tooling with C axis; Y axis; and spindle orient.

One way to succeed in today's competitive environment is to seek out partnerships with other industry leaders to mutually leverage each other's technology advances.

The Elite 27 MS turning center is unlike all machine tools with a 27-mm bar capacity spindle. It comes standard with a jaw chuck/collet-ready spindle, a 16-station turret top plate with live tooling, C-axis contouring and a subspindle. The machine weight of 7,820 lbs, along with the Harcrete-reinforced cast iron base, provides optimum rigidity, stiffness and high damping for exacting part tolerances and finishes, according to the company.

This Midwest manufacturer has found its niche in machining parts for the medical industry. Much of its success is attributable to its efficient use of single-spindle CNC turning centers. However, the company prefers to talk about what happens when the tool touches the metal, and let the results speak for themselves.

The SR-Series is a heavy-duty chuck and bar turning center that can be configured with many multitasking capabilities to machine complex small to medium-sized parts complete in one setup. With as much as 25 percent more torque and horsepower and 24 percent more speed than previous Hardinge turning centers, the SR 150 and 200 feature heavy-duty linear roller guides mounted to a Harcrete-reinforced cast iron base. Key attributes of the Hardinge SR-Series machines include spindle horsepower of as much as 30 hp and torque of as much as 270 foot pounds; hard turning and hard milling capability; and a control unit with high-speed milling capability and multi-axis functionality.

The Elite Series II turning centers feature enhanced flexibility and work envelope, the company says. Suited for either small-parts machining (1. 625" or 2.

The Hardinge SV 150 and SV 200 two-axis machines are made especially for high-volume production and job shop work. Features include a 20-hp spindle drive; pendent-mounted Hardinge/Fanuc-SV color LCD control packed with standard features; user-friendly operator panel; 45" one-piece cast iron base for high rigidity; large work envelope, which enables a larger cutting area; fast rapid traverse rate for increased productivity and decreased cycle time; large coolant capacity with 40 psi coolant pressure and more. Optional features include a fully programmable MT # 4 tailstock; part catcher; chip auger; chip conveyor; tool probe; high pressure coolant; and more.

Hard turning isn’t hard to do. However, it does require an understanding of the process dynamics and a systematic approach to the tooling involved. This article looks at how proper preparation will deliver consistent, predictable hard-turning results.

Increasingly, builders are responding to customer demands for part-processing flexibility and reduced part handling by designing machine tools capable of performing numerous operations within a single platform.

The Quest LMC42 from Hardinge Inc. is a self-contained manufacturing cell with four cutting zones that perform several machining operations. Selecting the desired configurations will allow the user to run one-piece lots, high-volume production and transference of bars or slugs for completing parts in one setup.

The company offers workholding products for Swiss turning applications, including round guide bushings that are carbide lined to keep the stock clean and unmarked. Hardened steel or Meehanite-lined bushings are available for stock that is not compatible with carbide. Custom guide bushings can be made for D-shaped or other extruded stock shapes and extended-nose headstock and emergency collets feature added nose length for doing pickoff work or to compensate for tooling interference.

The Talent 10/78 lathe features an ANSI A2-8 spindle with a 3" (78-mm) bar capacity and a 10" (254-mm) three-jaw power chuck as standard equipment. The 3,500-rpm spindle drive system offers a power rating of 25 hp (18. 5 kW).

HCAC collet adaptation chucks offer collet capability to jaw-chuck lathes. Benefits include faster job changeover, higher spindle speeds for reduced cycle times, more work envelope to machine longer workpieces, increased capability with interchangeable style S master pads, exact part length control and improved concentricity. Additionally, centrifugal force is not an issue with these adaptation chucks.

According to the company, its new Quest GT27SP super-precision gang tool lathe provides fast cycle times, fast setups and precise machining for profitable, lean manufacturing. This lathe is manufactured with a 5C collet 1 1/16" bar capacity spindle or a 16C 1 5/8" capacity option. An 8,000-rpm high speed spindle is featured on machines equipped with a 5C spindle.

The company will be displaying its Series II VMC machine with the new Siemens Sinumerik 810D control.
