Soft ungual chuck is applied to already machined the surface to regard fixed position as essence of life fiducial, the half fine vehicle of workpiece and car of essence of life have when large quantities of quantities are produced. It is when the work with turning greater batch, the fixed position precision when be being machined to improve work and the auxiliary time when managing workpiece is installed, bite use soft ungual chuck. For the basis real need changes diameter of ungual face circular arc and form at any time, the card that quenchs 3 ungual chuck is ungual, change block claw for mild steel, copper or aluminium alloy. If chuck claw is of two body, can change ungual ministry into soft metal; If block claw is an organic whole, a soft metal can be secured on card claw piece. After the treatment blocking claw of soft ungual chuck, can raise the fixed position precision of workpiece, so new 3 ungual chuck, the fixed position precision after workpiece is installed is less than 0.

01mm. Like 3 claw the planar whorl of chuck wears away more serious, precision is poorer, after changing soft ungual light treatment, the fixed position precision after workpiece is installed still can maintain in 0.

05mm less than. Soft ungual chuck installs clip to already machined the surface or soft metal, not easy clip hurts the surface. To thin wall workpiece, usable sector is ungual, increase to accumulate and reduce workpiece to be out of shape with workpiece interface. Soft ungual chuck is applied to already machined the surface to regard fixed position as essence of life fiducial, the half fine vehicle of workpiece and car of essence of life have when large quantities of quantities are produced. The adjustment with soft ungual correct chuck and turning, it is the first requirement that assures precision of soft ungual chuck. The underside of soft claw and fixed position stage, answer to slip to match and locate correctly with base blocking claw. Soft claw compares hard ungual lengthen with the share that places workpiece at installing 10 ～ 15mm, in order to have for many times turning, want check the number to assemble; The diameter of turning soft claw is best with be agreed by diameter of outfit clip workpiece, or big or small, unwarrantable outfit places precision. Diameter of general turning blocking claw is bigger than workpiece diameter 0.

2mm left and right sides, also be the workpiece diameter that is blocked namely, want to accuse solution to be inside limits of certain public errand; When turning soft claw, to eliminate gap, must be inside card claw or the picture column of one proper diameter or cirque are installed outside card claw, the position that they install in soft claw, answer to agree with the direction of workpiece clamp, otherwise precision of unwarrantable work location. When workpiece is clamp, columnar should clamp has a car inside chuck claw soft claw is ungual and, when workpiece is tightened to go up, cirque should be installed outside chuck claw, outside turning soft claw.
