TOOLING AND WORKHOLDING Modern Machine Shop 97 IN PARTNERSHIP WITH: Search Machines Smarter. Machining Center Drill/Tap Boring Mill Milling Machine Machine Type: The Machine Tool Search Engine Swiss-Type Hydraulic Chucks Clamp in Three Turns Big Kaiser says its hydraulic chucks for Swiss-type lathes are the first Swiss-type tooling improvement offered by the company 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, and parts for communication and digital equipment, 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 two or three turns for both clamping and unclamping. To maintain 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√óD 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 cool- ant-through connection and are available for Citizen and Star machines with 3 / 4 " or 22 mm straight shanks. | Big Kaiser | 888-866-5776 |
