Hobbing on a Turning Center
This manufacturer’s use of live-tool lathes overcomes labor cost in various ways. One of the latest sources of savings involves bringing another operation—hobbing—into these machines. INCLUDES VIDEO.
WatchSubspindle Turning System Designed For Large Diameters
Bardons & Oliver’s Big Bore subspindle machine is designed for challenging through-hole applications. The heavy-duty, column-style machine can process complex bar and tube components with virtually no limitations on diameter, weight or length, the company says.

The Quest CHNC turning center is available with either a 27-mm, 5C or a 42-mm, 16C collet-ready spindle. The machine is designed for high accuracy and quick job changeover to meet the 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 worldwide.
Read MoreMid-Sized Combination Lathe
According to the company, the M20 × 60 mid-sized combination lathe is flexible enough to handle a variety of work ranging from single-piece prototypes to high-volume production. The machine features a 15-hp spindle motor, a 20. 4" swing over the bed and a 10.
Read MoreTaking CNC To The Next Level On A Multi-Spindle
A new generation of multi-spindle automatic lathes from the Czech Republic may change the thinking about the best way to produce complex parts in small to medium volumes. An innovative drive system on these machines enables users to optimize spindle speeds for specific machining operations.
Read MoreHigh Performance Turning
The TMX series of slant-bed lathes from Hurco includes three turning centers: TMX8, TMX8MY and TMX8MYS, all of which include construction and high-performance specifications for efficiency. Specifications include rapids of 950 ipm (X axis) and 1,200 ipm (Z axis), a spindle speed of 14,500 rpm and a 36-hp spindle motor. The all-digital control, drives and motors along with absolute encoders on all linear axes provide superior surface finish capability, the company says.

The Hardinge Group has replaced the mechanical gearbox in the HLV toolroom lathe with an electronic servomotor and threading computer. This is said to both eliminate the need to purchase gears for different inch or metric threads and to ease left-hand threading. Thread range is 0.
Read MoreFour-Axis Turning Machine For Oil Pipes
EMAG’s USC 11/USC 21 series offers users a machine platform for the flexible machining of tubular components. The machine concept is characterized by the design of its “rotating tube,” which allows for complete machining of the external and internal connective sections of the oil pipes and minimizes the effort required for setup, the company says. The USC four-axis turning machine is said to offer shorter cycle times and provide higher-quality components compared with a two-axis machine.
Read MoreMulti-Spindle Production Center
The eight-spindle Mori-Say TMZ 867 CNC multi-spindle multifunction production center can accommodate barstock as large as 72 mm in diameter and can operate as an open-front chucker. The multi-spindle offers high precision CNC production capability to a range of part sizes that, until now, required other types of machines, such as rotary transfer machines, the company says. Provided with a double Siemens 840 D CNC, the machine offers as many as 72 CNC axes and can perform almost any metalcutting operation on precision parts including drilling, tapping, milling and hobbing.
