Tool Holders TRIZ Cases

Recessing the piston-operated section into the tool mount frees adjacent tool space, simplifies chuck changes, and preserves coolant supply.

An external motor drives axial tools directly, removing internal shafts and gears to cut turret size, maintenance, noise, and vibration.

A spring-loaded locking mechanism secures the adapter during tool disc rotation, preventing holder dropout in automated tool changes.

An open side-and-bottom groove routes sensor wiring in a rod-shaped holder, avoiding long through holes and lowering machining cost.

Cam quick-release elements replace threaded bolts to secure cutting units faster and let worn units be replaced without discarding the holder.

A locking lever and pressing member redistribute detachment force during tool exchange, reducing turret bending load and stress.

A movable sealing member keeps coolant directed through the tool passage while tool projection changes, preserving cooling and lubrication.

A collar with an annular groove creates positive locking in polygonal hollow-shaft spindles while saving space and improving axial positioning.

A recessed clamping jaw shifts contact away from the shank transition, preventing material buildup that can lock tools in the spindle.

A recessed clamping contact shifts load away from the flat-to-shank transition, preventing buildup that can jam tool removal in the spindle.

A retained movable locking pin blocks tool pullout while preserving concentricity and preventing pin loss during tool changes.

Independent spindle control lets standby tools accelerate, decelerate, and swap during machining to cut non-productive tool change time.

A self-locking clamping element and elastic drawbar raise clamping force and positioning accuracy while speeding automatic tool changes.

Raised contact faces on a machine tool probe mount reduce rocking on shank surfaces, improving alignment and measurement repeatability.

A slider-crank cam linkage moves a lock rod to quickly clamp or release a toolholder, cutting insert change downtime in metalworking.

A self-locking tie-rod clamp boosts tool holder retention and positioning accuracy while keeping automatic tool changes simple.

A two-piston clamp positions the locking piston away from the lever, allowing rotating tools to stay clamped without contact interference.

An axially sliding control bush with electronic phase shifting selects up to four tools in a rotary head while preserving rigidity for small-part machining.

A single actuator switches the valve only at the tool change position, simplifying hydraulic clamping without losing tool handling capability.

An elastic sleeve receptacle lets positioning pins absorb tool holder tolerances, enabling precise, lower-cost tool changes on machine tool turrets.

A detachable tool mounting member exposes the tool post drive mechanism for easier repair while preserving compact size and machining precision.

Two movable clamping elements and an ejection mechanism secure conical tool holding while pushing stuck tools out for easier removal.

A conical tension bolt lets hollow shaft clamping segments hold force without continuous actuation, reducing space and release effort.

A movable indexing-axis turret head switches tool positions without rotating the full turret, cutting lathe size, motors, and cost.

A turret surface placed closer to the turning axis reduces spindle interference and expands the B-axis tool turning range.

Two independent grippers automate tool swapping within a turret, removing manual intervention and streamlining tool arrangement.

Mounted tag readers let a tool stand register new tool data and delete removed tool data automatically, easing machine-tool changeovers.

Two movable clamping elements and an ejecting mechanism enable centric clamping while preventing jamming and easing tool removal.

Inclined upper and overhanging lower tool carrier supports enable simultaneous multi-tool machining with better access and flexible spindle-side layout.

Adjacent turret tool units are axially offset and shaped to clear the spindle, keeping tools near the chuck for heavy cutting.

A radially actuated drawbar uses inclined, self-locking surfaces to automate tool clamping where turret axial space is limited.

A self-locking tie rod clamp gives turret tool holders high clamping force and precise positioning while keeping automatic tool changes simple.

A crank wheel and linkage drive a lock rod to release and reclamp the toolholder quickly, cutting insert replacement downtime in metalworking.

Hydraulic actuators replace a gas spring to keep a tool holder securely locked in limited turret spindle space for automatic tool changing.

Slots and flanges in a toolholder canister replace bulky spring packs, cutting stiffness and saving space while preserving clamping compliance.

Offsetting the tool cutting edge from the X-Z plane reduces turret interference and allows larger workpiece diameters on a lathe.

A wedge clamping device integrates a coolant channel to deliver fluid directly to the tool cutting edge.

Replacing hydraulic circuits with a pneumatic cylinder and cam coupling eliminates bulky fluid systems while maintaining precise clamping force.

Segmenting the cam shaft into two formations allows reinforcing ridges on the drawbar, reducing its cross-sectional dimension for forward insertion.

A hydraulic expander assembly uses pressurized rams to securely hold lathe tool shanks within the turret channel.

An inclined surface deflects lateral machine element motion into axial holding forces, enabling larger tools within constrained turret space.

Relocating the filter downstream eliminates complex inlet clamping elements and prevents chip accumulation that hinders coupling operations.

A tool holder uses a slanted draw bolt and conical spindle pin to pull a clamping bolt, securing the tool with high precision.

Compression voids in the lock rod reduce stiffness, allowing adjustable clamping force without complex activation tools or large spring packs.

Inverting turret orientation to the rear eliminates manual rotation delays and protects operators from flying workpiece scraps.

An eccentric clamping device integrates a segment collet and actuating assembly within a spindle housing to secure tools with high precision.

A roller grooving tool positions a cassette via gap and protrusion features to maintain angular accuracy without manual operator adjustment.

Segmented clamping jaws with conical surfaces adapt to various tool holder geometries without modifying the turret body, resolving complexity trade-offs.
