The EXSYS/EPPINGER PRECI-FLEX Adapter System is continuously expanding to meet the toolholding needs of today's manufacturers. Joining the PRECI-FLEX line of high-precision modular tooling systems are the new Type 02 extended adapters and new Shrink-Fit adapters.
Type 02 extended adaptors within the PRECI-FLEX system feature extended collet chucks that allow tooling to be positioned closer into a machine spindle or chuck; because of their extended lengths, the adaptors eliminate any tool interference issues.
As part of the many different types of PRECI-FLEX adapters that adhere to the front face of the collet pocket, the Type 02 adaptors permit the use of smaller size collet diameters closer to those of the cutting tool to be used. This option provides more secure tool holding and the ability to clamp tooling at greater distances from the chuck, yet with the same rigidity as if using a standard toolholder.
EXSYS/EPPINGER adds all the benefits of shrink-fit tool holding technology to its PRECIFLEX system with the development of the company's new Shrink-Fit adapters. The adapters deliver 100 percent clamping and connectivity around a tool's entire shank diameter, while providing the holding power, rigidity and accuracy associated with shrink-fit tool holding.
The EXSYS/EPPINGER PRECI-FLEX modular tooling system was the first of its kind on the market to offer a single base holder and multiple tooling adapters that utilize the ER collet pocket, making lathe tooling changeovers quick, accurate and costeffective.
The product's compact design ensures maximum torque transmission and rigidity, resulting in increased machining accuracy and improved productivity. Available in a range of sizes and styles, PRECI-FLEX provides unsurpassed repeatability, with every toolholder offering repeatability within 3µm. The system also virtually eliminates machine downtime, and allows tooling adapters to be interchanged between fixed and rotary base holders for fast, economical machining.
Related Glossary Terms
- 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.
- collet
collet
Flexible-sided device that secures a tool or workpiece. Similar in function to a chuck, but can accommodate only a narrow size range. Typically provides greater gripping force and precision than a chuck. See chuck.
- 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.
- modular tooling
modular tooling
1. Tooling system comprised of standardized tools and toolholders. 2. Devices that allow rapid mounting and replacement of tools. Commonly used with carousel toolchangers and other computerized machining operations. See toolchanger; toolholder.
- shank
shank
Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.
- toolholder
toolholder
Secures a cutting tool during a machining operation. Basic types include block, cartridge, chuck, collet, fixed, modular, quick-change and rotating.
