Big Kaiser introduces hydraulic chucks for Swiss-type lathes, said to be the first Swiss-type tooling improvement offered by the company for in more than 30 years. These toolholders use a single wrench, enabling quick change of the cutting tools on a gang slide.

Often used for mass production of small items such as automobile parts, watch parts, medical parts, communication and digital equipment parts, Swiss-type lathes have many fixed and rotating tools operating in a narrow space, making it difficult to replace a cutting tool inside the machine. To minimize machine downtime and increase operator safety, the hydraulic chucks use a hex wrench that requires only 2 or 3 turns for both clamping and unclamping. 

To maintain good repeatability, once a hydraulic chuck is centered, the runout does not vary, even if a cutting tool is changed repeatedly, according to the company. Runout of less than 3 microns at 4×D can be achieved. With clamping ranging between 4 and 8 mm, the chuck promotes high-precision cutting. The company says that the chucks are long-lasting and that rigidity is improved by the short projection length and dual pressure points. The chucks have a standard pipe thread for coolant-through connection and are available for Citizen and Star machines with ¾" or 22 mm straight shank.

  • The Knob Problem

    The retention knob is an unmistakably critical component of the machining process. However, the tightening of the knob itself can lead to the toolholder not seating securely in the machine. You may be losing tool life to knob tightness without even knowing it.

  • Measuring Taper For Toolholders And Spindle Applications

    Companies concerned about strict quality requirements regularly check toolholder tapers for wear or inaccuracy because these conditions can jeopardize the results of a critical operation. However, a shop can check tapers quickly and reliably with air gages. These devices can be used effectively without special operator training. For measuring taper in a production environment, few other methods can match the speed and performance of air, as multiple-circuit air jets can be placed in very small taper gages.

    Hummingbird takes on machining work that is too small for most shops to handle. In fact, Hummingbird tries not to handle it either. To accurately machine the tiniest parts, this shop relies on processes that are as hands-off as possible.
