Taking 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.

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.

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.

The MultiSigma 8 × 24 produces complex parts in one setup. Eight independent spindles allow for high flexibility, while an integrated robot allows for the automatic unloading of parts into a pallet. The machine is supplied with the latest motorspindles, featuring synchronous motors.
Read MoreTurning Center with Collet-Ready Spindle
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.
Read MoreMultitasking Turning Center Offers Twin Spindles
The Johnford HT-30-2SD high precision, CNC turning center is built for industries that require the productivity of a two-spindle turning center. This 45-degree slant-bed machine features a 30-hp, double-wound main spindle that delivers high torque at low rpms. There is also a 15-hp, double-wound subspindle.

In-Machine Robot Provides Gantry System Alternative
Fortune International offers its VT series lathes with an integrated robot in place of a tailstock, a configuration that is said to significantly reduce part-changeover time compared with an external gantry robot.
Read MoreAutomated Turning For Small And Large Batches
The VL-Y from Emag is fully equipped with a Y axis (50-mm travel); a chip conveyor; a machining area extraction unit; a fluid-cooling system for spindle motor and turret; and automation equipment for loading and unloading workpieces. The machine features a recirculating workpiece storage conveyor on which “carrier prisms” deliver raw parts and collect the finish-machined components from the pick-up spindle. The pick-up station is located behind the machining area, so the operator can continue removing finish-machined components and inserting new raw parts into the carrier prisms at the front.
