Chucks

The Hyperturn 200 Powermill high-performance milling-turning center from Emco is for machining large workpieces up to 1,000 mm in turning diameter and for lengths up to 6,000 mm, workpiece weight of 1,500 kg in the chuck and up to 6,000 kg between chuck and tailstock. The powerful main spindle is designed for heavy cutting with a maximum torque of 6,410 Nm and 84 kW.

Lexair’s full-bore, fixed-length, self-contained collet chuck allows full-capacity spindle operation, due to elimination of the drawtube. When using the full bore chuck, spindle capacity is boosted as much as 30 percent, and clamping pressure is unaffected by centrifugal force, regardless of rpm, according to the company.

Northfield Precision Instrument Corp. reported that when a customer requiring a highly specialized diaphragm chuck was not finding success with other chuck manufacturers, they turned to Northfield Precision Instrument. The chuck needed to be submersible for use in a wire EDM. To achieve this, the engineers at Northfield designed a specialized chuck with all non-stainless steel wetted parts.

Rockford Systems offers a line of electrically interlocked safety shields for cutting and turning machines that protect operators against flying chips, sparks, debris, and coolant. The electrical interlock prevents machines from starting until the shield is positioned safely in front of the hazardous area, also called the point-of-operation.
