OK-VISE product catalog

Product catalog summary

Company Profile
OK-VISE Oy, founded in 1984 and based in Finland, specializes in low-profile clamps for industries such as metalworking, plastic, aerospace, and electronics. Known for innovative clamping solutions, the company provides products that enable three-directional machining with high clamping force and efficiency. Their products are globally distributed and recognized for quality.

Operating Principle
OK-VISE clamps expand when tightened, securing workpieces against guides to prevent movement. They offer a clamping force up to 150 kN and are suitable for both single machines and large manufacturing systems. The clamps are available in various models, including single and double-wedge constructions.

Product Specifications
Standard models have a hardness of 48-52 HRC with serrated jaws, though smooth jaws are also available. Made of tool steel and through-hardened, the clamps come in models like BK2-VT-SO and BK2-VT-O, each with specific dimensions and clamping forces.

Cost Efficiency and Stability
Designed for cost efficiency and stability, OK-VISE clamps rely on fixed stoppers and guideframes for precision. They are effective in clamping force and available with Viton o-rings or regular springs.

Ultimate Efficiency and Three-Directional Machining
The low-profile design allows for flexible three-directional machining, enhancing accuracy and reducing quality control needs. The clamps are small, lightweight, and suitable for both manual and CNC machines.

Special Models
Special models include those with machined female threadings for quick use, machinable jaws for custom shapes, and self-adjustable models with ball pressure screws for irregular parts.

Rotary Pallet System
OK-VISE offers rotary columns made of aluminum with steel corner clamps, improving machinable area efficiency and reducing tool changes and operator intervention.

Specifications and Features
OK-VISE clamps offer flexibility with stepless movement in t-slots, allowing adjustments for changing part sizes. The RPS system includes models like RPS-T30, RPS-T40, RPS-T50, and their double variants, each with specific dimensions and nut types.

Subplates, Corner Clamps, and Fixed Stoppers
Adapter plates locate and lock trunion units for the RPS system. Subplates allow quick part changes by mounting workpieces and clamps to columns. Aluminum subplates are 22 mm thick, and steel corner clamps are designed for M10 socket head screws. Six types of standard fixed stoppers are available for rotary columns.

Company Background
Part of the Kytola Group, OK-VISE Oy is known for expertise in lubrication and seal water monitoring, with a history dating back to 1906.

Warranty Information
OK-VISE offers a 10-year warranty on the quality of raw materials and craftsmanship of wedge and jaw parts, excluding components like blackening, springs, and sideplates. The warranty covers defects but not damages from machine malfunction or misuse.

SUBPLATES, CORNER CLAMPS AND FIXED STOPPERS TO COMPLETE THE RPS > Columns especially in machining centres are not normally thought of as quick-change devices. However, when column is combined with flexible subplates, users can gain the advantage of quick part changes. Rather than mounting workholding to a column the workpieces and clamps canbe mounted to subplates that in turn are mounted to the columns faceswith corner clamps. Specially fitted aluminium subplates are available for each trunion unit.Thickness of the plate is 22 mm. Steel made Corner clamps are designed for M10 socket head screws...
