UNILOCK MODULAR WORKHOLDING SYSTEM VOL. 2

ZERO-POINT CLAMPING SYSTEM Meeting the challenge to set up every process as efficiently as possible with a simple clamping concept. In a competitive environment, all production cells need efficient workpiece handling solutions. Production diversity should not be a barrier. Let Unilock’s zero-point clamping system lead the way with efficient part loading solutions for low and high volume production runs. Unilock virtually eliminates all setup time and replaces it with production time. If your company needs to increase its agility, Unilock will allow you to run any job on any available...

SERVICE & OPERATING INSTRUCTIONS

OVERVIEW How it Works Unilock utilizes spring pressure to drive multiple clamping pins against a tapered clamping knob. Air pressure is used to compress the springs to back the clamping pins off of the clamping knob. This clamping process is achieved by bleeding the air pressure out of the chuck. To facilitate palletization, the clamping knob is attached to a base plate, fixture or directly to a workpiece. The result is quick and repeatable clamping. A hand locking version (no air required) is also available. Features: • Clamping Mechanism: Heavy-duty die springs • Chuck Opening: Air...

OVERVIEW SBC Knob Diametral Clearances Multiple Chuck Applications Unilock is not restricted to one clamping knob. When the fixture or workpiece exceeds the work range of a single Unilock chuck, additional clamping knobs and chucks can be used to provide the necessary support and stability required for the process. There are only a few limiting factors as to the size of an array of chucks or in the weight of a workpiece. Undersized knobs provide clearances for large parts or out of position locations. • SBA = Establishes centerline • SBB = Orients about centerline • SBC = Clamp only, no...

OVERVIEW Process Your Way to Savings Fixtures and workpieces are easily adapted to Unilock clamping knobs. Tremendous savings are available if the fixture or workpiece can be reoriented or transferred to machine additional features while remaining attached to the Unilock clamping components. On horizontal machines with columns, fixtures can be rotated 90 degrees or moved to the top. Transferring fixtured parts through as many operations as possible eliminates additional fixtures and clamping/unclamping time. Less clamping and unclamping of parts also reduces scrap and improves...

OVERVIEW It’s Easy to Get Started Starter Kits help save time between part changes. Chucks are pre-mounted to a base plate which functions as a reference edge. With a single part number you get all the required components to be up and running immediately. Working Solutions in Minutes Table chucks are mounted to base plates and are ready to be clamped to your workstation. These chucks are supported by pre-assembled pallets. Shown below are the Mono, Duo and Quad table chucks, along with their pallets. Pneumatic kits are also available so you can install a working solution in minutes. Build...

APPLICATION EXAMPLES A Clamping System Flexible Enough to Change the Entire Table or Workpieces and Fixtures Unilock establishes predefined datums on all of your machines. When you load, lock and hit cycle start, there is no wasted time. A setup should always take the same amount of time. Unilock delivers scheduling flexibility and setup versatility. By using more than one chuck on a machine, you will be able to switch between multiple small parts or fewer large parts. Our predefined datums allow you to quickly and accurately convert your machining center from a headstock and tailstock...

APPLICATION EXAMPLES LARGE & SMALL PARTS Large Parts Even Your Largest Machines Can Save Money Starting With Your Next Job Unilock provides undersized clamping knobs so you do not have to hold .0004" on fixture locations when your production tolerance is .005". These undersized knobs are a necessity if you want to mount knobs directly to warped or loosely toleranced workpieces. If you do not need to, or cannot hold a tight tolerance, simply select the appropriate undersized clamping knobs to accommodate your workpiece or fixture. Unilock’s heavy-duty clamping knobs are a necessity when you...

ROUND CHUCKS The round Unilock chucks come in diameters from ø90mm to ø196mm (ø3.543" to ø7.716") and body styles to fit a wide variety of applications.
