Technical Information KM™ Clamping Units Manual Clamping System Characteristics • KM Manual Quick Change tooling is the most economical way to reduce downtime for setup and tool change and is an important first step toward further automation. The machine tool builder or the customer can easily install KM Manual Quick Change tooling. • All KM manual clamping units require approximately three turns of the activation screw and a specified amount of torque to lock the cutting tool. • The KM Manual Quick Change clamping mechanism is rigid and compact, with an easily accessible activation screw. The high mechanical advantage of the ball track makes it simple to apply the required locking force. • All KM Manual Quick Change clamping units accept external and internal cutting • The KM Manual Quick Change clamping mechanism can adapt to a wide variety tools. Right- or left-hand tooling can be used interchangeably, and cutting tools of machine tool mounting configurations including flange mounts, square, round, can be inverted if required. KM Manual Quick Change clamping units support and VDI shanks. through-the-tool coolant. KM-LOC II™ Clamping System The KM-LOC II clamping device is the latest addition to the WIDIA™ KM modular quick-change tooling family. An evolutionary step from the conventional KM manual clamping system, the KM-LOC II employs a cam and a preloaded disc spring pack to provide positive, stop-to-stop locking and unlocking in only 145° of movement. The spring pack supplies the correct clamping force without using a torque wrench, while the cam permits quick and easy clamping/unclamping in less than one half of a turn. The KM-LOC II clamping device is compact to adapt to a wide variety of machine tool mounting configurations including flange mounts, square, round, and VDI shanks. The KM-LOC II is capable of handling through-the-tool coolant pressure of The latest KM-LOC II clamping device offers all of the features and benefits of our 100 bar (1500 psi), and the design permits lubrication of internal components industry-proven KM Modular Quick Change Tooling System and reduces the time without disassembly. The design also enables the external installation of an required for manual tool changes. orientation screw that restricts the cutting tool to a single orientation. Automatic Clamping System • Spring-Pack Activated Characteristics Automatic KM clamping systems enable tools to be locked or unlocked with the push of a button by the machine operator or changed automatically by the machine tool. These units also allow tools to be changed quickly and provide a high level of automation at a moderate cost. Operation The pull on the lock rod for the automatic KM clamping unit is provided by disc springs that are an integral part of the clamping unit. Release is accomplished by pushing on the back of the clamping unit with a hydraulic cylinder mounted on the turret assembly. Many machine tool builders design and build the turrets for their machines to be equipped with the KM Automatic Clamping Units. K12 WWW.WIDIA.COM Technical Information
