Swiss-Type Hydraulic Chucks Clamp in Three Turns
Big Kaiser introduces hydraulic chucks for Swiss-type lathes, which is said to be the first improvement to this technology in more than 30 years.

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
I’ve said that the toolholder is the least appreciated element in many milling processes, but the pull stud (or retention knob) is perhaps the least appreciated component of the toolholder.
Horn USA has developed quick-change tooling systems to drastically reduce set-up and toolchange times for Swiss-type lathes, including those with through coolant.
A reader recently asked about speed, feed rate and depth of cut when using small tools in steel.
