OK-VISE® is a well-recognized international trademark, best known as an original inventor and manufacturer of the wedge-operated Low-profile Clamps. Today OK-VISE® Fixturing Concept includes several systems, which enable customers to build fixturing with ease never previously experienced.
OK-VISE® products are used in workholding, especially in fixtures used in machining centers and milling machines. With OK-VISE components a variety of workpiece types, sizes and materials can be securely held on all possible workholding platforms.
The OK-VISE® Story
In the early 1980s Finnish entrepreneur and inventor Olli Kytölä (“OK”) bought his first NC machining centers. Soon he became frustrated with the large size and small clamping force of machine vises and other workholding systems then available on the market for his brand new machines.
Once, when hanging laundry at home, he started thinking whether some sort of device similar to the screw anchor he used for attaching the clothes line to the brick wall could also be used in fixturing. His main goal was to achieve a high and accurate clamping force with a small device. The rest, as they say, is history – OK-VISE low-profile clamps had been born.
Today their products are available through a global distribution network. As a result of constant product development and dedicated customer service, their name stands for quality in every respect and OK-VISE® has become a recognized registered trademark around the globe.
OK-VISE® Workholding Clamps and Accessories
OK-VISE® Low-Profile clamps
Small in Size – Giant in Performance
Olli Kytölä’s original invention is still the core of our product range. This unique workholding solution is designed to meet the demands of the modern metalworking, plastics, aerospace and electronics industries.
OK-VISE® Generic Purpose System
OK-VISE’s GENERIC PURPOSE workholding system adapts easily to various workpiece sizes, and the components of these systems can be reused and reconfigured easily for a variety of applications and workpieces.
OK-VISE® Dedicated Fixturing
OK-VISE’s Blank system is a system for building DEDICATED FIXTURING. Normally only one setup of one workpiece can be clamped with these fixtures. This is typical in high-volume production or when special optimization of the fixture is needed.
OK-VISE® Method of Automated Clamping
As the original inventor of the wedge-operated low-profile clamp, OK-VISE has introduced hydraulic actuators that are optimized to utilize the well-known properties of the OK-VISE clamp: extreme clamping force in a small space combined with the accuracy of the clamping force. As an integral part of the OK-VISE Fixturing Concept, hydraulic actuators can be used to build truly modular fixtures.Hydraulic clamping can used in combination with
- Automated or manual workpiece loading
- Vertical or horizontal machining centers and 5-axis machines
- Live systems (continuous pressure supply) or decoupled system
OK-VISE is continuously developing new automated modules for robotic loading, and also for manually operated systems where automation saves operator’s loading time and improves ergonomics.
OK-VISE® Low-Profile clamps
Clamps with Smooth Jaws
When no marks on the workpieces are permitted, smooth jaws are employed.
Clamps with Serrated Jaws
A general-purpose clamp for your workshop. Serration creates high friction, which ensures reliable clamping in any circumstances.
Thanks to their small size, these lightweight clamps are easy to lift and install. Moving them from one application platform or machine to another is hassle-free. High accuracy is achieved by grinding all the moving surfaces of the clamping unit to a precise angle. Strict quality control is performed on each stage of the production cycle.
A key feature of the OK-VISE low-profile clamp is its cross-wedge construction in both the horizontal and vertical plane, which means that the clamp is locked firmly in every direction as it is tightened down. This eliminates the possibility of measurement error due to sliding. DK2-VT comes with serrated jaws. The inch model code is DK2-VTI.
Clamps with Machinable Jaws
Single-wedge clamps are also available with extended jaws and can be machined to suit the geometry of the workpiece. The smallest model can be machined up to 3 mm and the larger ones up to 5 mm.
OK-VISE® Generic Purpose Systems
Multi-Rail RM System
OK-VISE MULTI-RAIL RM System is the best-selling generic purpose system of OK-VISE. Compared to a traditional machine vise, the Multi-Rail system offers the following benefits:
- Using the components of the system, even the most challenging workpiece types can be machined
- All sides of a workpiece can be machined with two setups
- Multiple workpieces can be clamped simultaneously
- Workpiece will be safely fixtured in all conditions
- It is also possible to clamp very large workpieces
- Multi-Rail RM system modules are the most accurate multiple clamping modules on the market, most of them giving 10 micron accuracy
- Maximum clamping force that can be applied to the base rail is 6 metric tons ( 60 kN)
All modules of the OK-VISE Fixturing Concept are reusable
