HYDRAULIC CHUCK OVERVIEW
HYDRAULIC CHUCKS FOR SWISS-TYPE AUTOMATIC LATHES Hydraulic chuck system provides high accuracy and easy tool changes.
Improved Accuracy and Rigidity The lathe type hydraulic chuck was developed from decades of knowledge accumulated on milling machines. In addition to high accuracy and rigidity, the slim design helps avoid interference with adjacent tools.
Safe and Quick Operation The ability to change cutting tools with a single T-wrench drastically reduces the time required for tool changes. It also reduces the need to work in extremely limited spaces and improves operator safety.
±1μm Repeatability Even changing the tool, the repeatability at 4D is stable at ±1μm or less. In addition, the tightening is completed when the clamping screw hits the bottom, controlling tightening torque is not needed.
No Change in Tool Length Since the tool projection length does not change after the clamping, it is easy to control the tool projection length in the machine.

THREE TYPES FOR DIFFERENT TOOL POSTS Standard Type F Type
R Type ype
• Unique design for use with both upper and lower sections without interference • Tightening at an offset position in the tool side • Coolant delivery with M6 is possible when mounted on the upper section hboth
• Tighten from the opposite side of the tool • Coolant delivery is possible with Rc(PT)1/8 screw • Optimum overall length for easy use • Ideal for use on a front tool post
• Tighten from the tool side • Coolant delivery is possible with Rc(PT)1/8 screw • An adjusting screw can also be fitted (some models) • Length can be adjusted by cutting the shank • Easy to install in various tool posts
