The ZG and ZS (pictured) manual lathe chucks from Röhm Products of America feature enhanced designs that include control edges for adjustability, safety adapters to regulate force and spray water rims that protect machine tool spindles.
The control edges on the chuck bodies allow for fast and simple on-machine scroll adjustments. The new safety adapters on the chucks let users easily set and control clamping force via a torque wrench, a capability especially beneficial when machining deformation-sensitive workpieces. Located at the upper edges of the chucks, the spray water rims redirect cutting fluids away from machine spindles to help prevent contamination and increase their working lives.
The ZG and ZS manual chucks are available in diameters from 2.9" to 49.2", as well as with a full range of clamping jaw options for all machining requirements. Users can also> choose between the basic (steel body drop forged) and economy (vibration-damping special cast iron body) chuck versions.

- chuck
chuck
Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.
- lathe
lathe
Turning machine capable of sawing, milling, grinding, gear-cutting, drilling, reaming, boring, threading, facing, chamfering, grooving, knurling, spinning, parting, necking, taper-cutting, and cam- and eccentric-cutting, as well as step- and straight-turning. Comes in a variety of forms, ranging from manual to semiautomatic to fully automatic, with major types being engine lathes, turning and contouring lathes, turret lathes and numerical-control lathes. The engine lathe consists of a headstock and spindle, tailstock, bed, carriage (complete with apron) and cross slides. Features include gear- (speed) and feed-selector levers, toolpost, compound rest, lead screw and reversing lead screw, threading dial and rapid-traverse lever. Special lathe types include through-the-spindle, camshaft and crankshaft, brake drum and rotor, spinning and gun-barrel machines. Toolroom and bench lathes are used for precision work; the former for tool-and-die work and similar tasks, the latter for small workpieces (instruments, watches), normally without a power feed. Models are typically designated according to their “swing,” or the largest-diameter workpiece that can be rotated; bed length, or the distance between centers; and horsepower generated. See turning machine.
