Small, Screw-Down Clamp for Various Tables, Fixtures
The Kurt MiniLock is a small, low-profile screw-down clamp designed as a cost-effective, easy-to-use option for rigidly clamping components on machine tables, fixture plates, tombstones and trunnion fixtures.
The Kurt MiniLock is a small, low-profile screw-down clamp designed as a cost-effective, easy-to-use option for rigidly clamping components on machine tables, fixture plates, tombstones and trunnion fixtures. The versatility of the clamp is said to enable machinists to plan the parts to be machined, the quantity of production runs and the specific machining center to be used, maximizing resources and eliminating dysfunctional workholding setups that deter productivity.
The clamp is operated with a quarter turn to the screw. The clamp jaw of the MiniLock expands to engage the part and is forced both laterally and down, clamping the part and preventing it from lifting. It has a small circumference and can be positioned around or between workpieces. It also accommodates with workstops.
The clamping jaw is machined of aluminum bronze with a steel alloy actuating screw. It is available in four sizes: 0.688", 0.875", 0.938" and 1.125" (17.476, 22.250, 23.826 and 28.575 mm). Hex thickness ranges from 0.188" to 0.375" (4.776 to 9.525 mm). One package contains six MiniLocks.
Modular fixturing makes sense for this manufacturer, whether it's machining one- or two-of-a-kind parts for its custom machine tools or larger quantities for its contract machining business.
These vise jaws use protruding, mechanical pins to repeatedly support workpieces either horizontally or at angles. They are said to allow quicker setups than conventional parallels.
Finding a way to fixture contoured marine propellors proved to be this shop’s biggest challenge in developing an effective automated machining cell.
