HYDRAULIC CHUCKS FOR SWISS-TYPE AUTOMATIC LATHES

HYDRAULIC CHUCKS

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.

Repeatability Less than 1µm

THREE TYPES FOR DIFFERENT TOOL POSTS Standard Type F Type

R Type

•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.

•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.

•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.

Use only cutting tools that have a shank tolerance of h6. Do not use with cutting tools made with a flat on the shank (ie: Weldon type shank). Do not tighten the clamping screw without first inserting a cutting tool into the tool holder. Always insert the cutting tool into the hydraulic tool holder beyond min. clamping length “E.” ! CAUTION

*Some coolant comes out from the inner slots in the coolant-through application • Adjusting screws cannot be used with models marked v • Adjusting screw is adjustable both from the head and shank ends • “E” is the min. clamping length • “G” is the adjusting screw (optional) • “H” indicates the adjustment length with an adjusting screw • “H” at HDC8/10/12 is the max. tool shank length can be inserted for these models • L 1 is the minimum length, in case of shortening the shank
