Featured Product Information

CL5® Quick-Change 5-Axis Workholding
The CL5® 5-axis workholding system is a quick-change tooling system specifically designed for 5-axis workholding. CL5® 5-axis workholding fixtures include a wide range of solutions for all sizes of rotary tables. CL5® 5-axis workholding solutions can be classified into three general areas, making use of either a fixture plate mounted on a rotary table, a Quintus quick-change riser mounted on a rotary table or subplate mounted on a rotary table. CL5® 5-axis workholding accessories, including locating keys and bolt sets are also available. 
Carr Lock® System
The Carr Lock® System allows accurately locating and clamping at the same time, with just the turn of a hex wrench and is Ideal for mounting quick-change tooling on a subplate. With the Carr Lock® System, Each mounting point consists of three components: (1) a Carr Lock® Clamp, with a precisely ground shank; (2) a Carr Lock® Liner Bushing in the top plate; (3) and a Carr Lock® Receiver Bushing in the subplate. This compact assembly of the Carr Lock® System provides considerable hold down force, together with an incredible +/-.0005" repeatability.

Floating Clamps
Floating Clamps are position-flexible clamping devices. The top jaw and bottom jaw together provide a floating clamping point that adjusts to the workpiece before locking, to prevent deformation. These combination clamp/supports are often used in conjunction with primary locators and clamps, providing additional support points to reduce machining vibration. Floating Clamps are especially useful for clamping forgings, ribbed or flanged castings, and other larger parts.

To initiate clamping, push the Floating Clamp downward, then immediately swing the jaws into clamping position. The clamping jaws will automatically rise so that the bottom jaw contacts the workpiece with a light spring force. Next, tighten the top hex nut 11 ft-lbs minimum to 22 ft-lbs maximum, depending on the support load capacity desired. During the tightening process, the workpiece is clamped and simultaneously supported.

For custom applications, the standard upper clamping jaw supplied can be replaced by a special clamping jaw.
DropZero™ Modular Zero-Point System
Our new DropZero Modular Zero-Point System enables you to completely machine a workpiece in one setup, significantly reducing setup time and fixturing costs. With a few quick turns of a wrench, DropZero clamping modules locate, support, and securely clamp the workpiece from underneath, providing full machining access to 5 sides.

Clamping modules can be mounted exactly where required, anywhere on the fixture plate. These modules fit perfectly on all of Carr Lane’s 1/2” and 5/8” modular tooling plates and blocks, but can also be used with non-modular tooling. Clamping modules elevate the workpiece for machine-spindle clearance, and are stackable for extra height.

Pull-down studs must be fastened to the underside of the workpiece. Most setups require one zero-point stud (for primary two-axis location), one diamond stud (for single-axis location), and one or more floating studs (for additional support and clamping without location).
Captive Jig Pins
Similar to a standard Jig Pin, except that the pin body is positively retained in a locking bushing. In fully retracted position, the bushing's spring clip snaps into the pin's groove. This holds the pin fully retracted by spring force and positively prevents removal. Spring pressure also holds the pin in intermediate extended positions, an advantage especially if the fixture is turned upside down. Like standard jig pins, Captive Jig Pins have an integral shoulder to keep the handle raised. Available in pin diameters from 3/16 to 1/2". Made in USA.

The complete assemblies listed below include a Captive Jig Pin, Locking-Pin Bushing, and Lockscrew. Choice of standard or long bushing in most sizes, for installation in thinner or thicker plates. Locking-Pin Bushings are designed to press fit in a standard reamed hole, and can be further secured with the included Lockscrew to positively hold the bushing in place.
Captive Locating Screws with Hand Knob
These Captive Locating Screws have an integral hand knob for tightening by hand. Captive Locating Screws can be used for locating and clamping, or for clamping only, by selecting the appropriate screw length. The locating screw's precision-ground body is positively retained in a locking bushing. In fully retracted position, the bushing's spring clip snaps into the body's radial groove. This holds the screw fully retracted by spring force and positively prevents removal. Spring pressure also holds the screw in intermediate extended positions, an advantage especially if the fixture is turned upside down. Available in thread sizes from 1/4-20 to 1/2-13 (M6 to M12 in metric). Made in USA.

The complete assemblies listed below include a Captive Locating Screw, Locking-Pin Bushing, and Lockscrew. Choice of standard or long bushing in most sizes, for installation in thinner or thicker plates. Locking-Pin Bushings are designed to press fit in a standard reamed hole, and can be further secured with the included Lockscrew to positively hold the bushing in place.
Headed Slotted Locator Bushings (Press Fit)
Now also available in stainless steel!

Slotted Locator Bushings can be used with many types of alignment pins and locating pins to align two holes without binding. Precision bushing with a tight tolerance in one direction and full relief in the perpendicular direction. This headed version provides more resistance to axial loads. The head can be left exposed, or recessed by counterboring the installation hole. Available for pin diameters from 3/16 to 1/2" diameter. Optionally available in hardened 440C stainless steel. Made in USA.
ON-SIZE® Bushings for Bullet-Nose Dowels – Head Type
ON-SIZE® Bushings are made from Invar 36, a 36% nickel-iron alloy that has an extremely low Coefficient of Thermal Expansion. Invar material is particularly useful in applications where minimum thermal expansion and high dimensional stability is required. Useful in high temperature applications up to 750°F (400°C), these products will maintain their size and accuracy even under heat-cool multiple cycles.

The precision bushings shown here are used with Bullet-Nose Dowels to align two pieces of a fixture. The bushing's ID and OD are concentric to within .0003" TIR. Available for pin diameters 1/4, 5/16, 3/8, and 1/2" (6, 8, 10, and 12mm in metric). Available in head and headless types. Made in USA.
LIFE-EX® Round & Diamond Pins
Now available with LIFE-EX® coating!

Popular sizes of Round & Diamond Pins are now available with our proprietary LIFE-EX coating. This PVD coating is very hard, abrasion resistant, and slippery, resulting in a component that has a longer lifecycle for high-production applications. This extended lifecycle allows these items to remain in production longer with less need for replacement than standard uncoated items.

Round & Diamond Pins are precision locating pins with a chamfered tip for easy part loading, and a shoulder to resist downward forces – important advantages over standard dowel pins. One Round Pin and one Diamond Pin are often used together to locate from two machined holes in a workpiece, or to align two pieces of a fixture, without binding. Diamond pins are relieved, to locate only in 1 axis. Head and shank diameters are concentric to within .0005" TIR. Made in USA.
Captive Clamping Pins with Knurled Knob
These Captive Clamping Pins have a knurled knob for tightening by hand and a pin body that is positively retained in a locking bushing. In fully retracted position, the bushing’s spring clip snaps into the pin’s radial groove. This holds the pin fully retracted by spring force. These pins also incorporate a positive thread stop (the .10”-long unthreaded portion with a square shoulder, above the threads) to positively prevent screwing the pin past the spring clip. Spring pressure also holds the pin in intermediate extended positions, an advantage especially if the fixture is turned upside down. Available in fine-thread sizes from #10-32 to 3/8-24. Made in USA.
