Kurt Workholding offers a complete line of high-density CarvLock workholding towers for precision machining with eight or 12 clamping stations in both manual and hydraulic models. Equipped with easily changeable jaws, these Kurt towers enhance setup flexibility and provide fast changeover between jobs.
Kurt’s complete line of CarvLock tower system options allows manufactures to configure one that fits their exact needs. They are suitable for use on mid-size and larger horizontal machining centers. Each tower station has either a 3 or 4 inch jaw opening and provides repeatable clamping to 0.0002 inch with a maximum clamping force of 5,870 to 7,460 lbs., depending on model.
Kurt’s CarvLock Tower feature self-adjusting holding blocks for clamping the same or dissimilar sized parts. Fast manual operation is enhanced with the adjustable preload feature that reduces handle turns for opening and closing clamping stations. The hydraulic CarvLock Towers achieve the fastest part clamping by eliminating the need to manually clamp the piece part.
Kurt’s CarvLock Towers are manufactured of ductile iron, reportedly insuring maximum strength, rigidity and long-term accuracy. The elevated-column design makes clearing chips and coolant from the clamping area fast and easy. Additional features include jaw options for specific applications including: hard jaws, machinable aluminum and machinable ductile iron jaws plus aluminum fixture plates. For enhanced flexibility, jaws are indexable 180 degrees.
Related Glossary Terms
- centers
centers
Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- fixture
fixture
Device, often made in-house, that holds a specific workpiece. See jig; modular fixturing.
- precision machining ( precision measurement)
precision machining ( precision measurement)
Machining and measuring to exacting standards. Four basic considerations are: dimensions, or geometrical characteristics such as lengths, angles and diameters of which the sizes are numerically specified; limits, or the maximum and minimum sizes permissible for a specified dimension; tolerances, or the total permissible variations in size; and allowances, or the prescribed differences in dimensions between mating parts.
