EMAG Unveils Technology School
The Emag Technology School USA hosted its first class January 9 at machine tool builder Emag’s U.S. headquarters facility in Farmington Hills, Michigan.

Vertical Turning Machine Offers Pendulum, Tailstock Options
The VT 2 vertical pickup turning machine can be equipped with pendulum technology for machining chucked components with 100-mm maximum workpiece diameters or with a tailstock for machining shaft-type components with 400-mm maximum lengths.

Road Report: Wish You Were Here, Day 3
Where in the world is Chris Koepfer, editor-in-chief of Production Machining? Today, he's learning about the latest manufacturing technology in southern Germany.

How Electro-Chemical Machining Works
Machine tool builder EMAG has produced a very nice video that explains and illustrates how the electro-chemical machining (ECM) process is able to perform simple deburring operations as well as produce precision surfaces and shapes.

Automotive Machining in Motion
A number of videos showing innovative ways to manufacture automotive components has recently been added to MMS Online. Read about the technologies here and then click to see them in action.

Vertical Turning and Grinding Centers
Emag’s vertical turning and grinding centers—VSC 250 DS, VSC 400 DS and VSC 400 DDS—are said to combine the advantages of vertical hard turning and grinding in a single machine.

Crankshaft Grinding Process Reduces Cycle Times
Emag’s VTC 315DS vertical grinder is designed for synchronous support grinding of crankshafts, which is said to combine high flexibility and high productivity. In this process, two opposing CBN wheels machine the same point on the workpiece to cancel out axial forces generated in the feeding direction.

Four-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.

Automated 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.

A New Spin On Vertical Grinding
Simultaneous, dual-wheel vertical grinding offers advantages for finishing bearing surfaces and other critical features on shafts. Having two opposing grinding wheels in contact with the workpiece at the same time neutralizes axial forces and shortens cycle times.

Vertical Turning Centers Suitable For Small And Large Part Batches

Redefining Multi-Spindle Machining
The premise of this mega-multi-spindle machine design is to provide a dedicated spindle for every tool required to machine a part. It proves most effective for applications in which tool change takes longer than the cutting operations.

• Video: Dual-Wheel, Vertical Grinding of a Camshaft

  In this video, one of EMAG's VTC machines grinds a camshaft using two opposing grinding wheels. Opposing the wheels in such a way cancels axial forces on the camshaft.
