GENERIC FIXTURING CONCEPTS Multi-Rail RM System Multi-Rail RH System Grid Fixturing System Combo-Rail 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). More info can be found in Multi-Rail RM System.

OK-VISE® Multi-Rail RM System

OK'VISE Fixturing Concept This is the shortest rail, with two 12 mm H7 positioning holes. A rail 200 mm in length provides better adjustability than the shortest RM-100 rail. ! 012 H7 x 2 x 012,5_ OK-VISE® Multi-Rail RM System C07092021 16.9.2021 3

OK'VISE Fixturing Concept This length rail is most commonly used to replace old-fashioned machine vises. On Multi-Rail base rails L=400...700 mm, positioning hole is the second one from the end of each rail. Please note that the end of the rail is different from the start. The numbering of the scale starts from the left. OK-VISE® Multi-Rail RM System C07092021 16.9.2021 4

Base rail RM-500 A good universal rail for VMC and HMC machining. Base rail RM-600 This rail length is very popular on tooling blocks. OK-VISE® Multi-Rail RM System

OK'VISE Fixturing Concept This is the longest standard rail produced by OK-VISE. Special length rails (also longer than RM-700) are also available. RMC-DR This clamp module features a D-series clamp with two serrated jaws. OK-VISE® Multi-Rail RM System C07092021 16.9.2021 6

RMC-DS This clamp module features a D-series clamp with two smooth jaws (S). In the clamp modules RMC-DSx, one jaw is smooth and another jaw is of another type. For example, in RMC-DSR one jaw is serrated. RMC-BR This clamp module features a B-series clamp with two serrated jaws. RMC-BS This clamp module features a B-series clamp with two smooth jaws. OK-VISE® Multi-Rail RM System

RMC-DTx The clamp module RMC-TTx features a D-series clamp with two jaws for an additional piece (T). In the clamp modules RMC-DTx, one jaw is for additional piece jaw and another one is of another type. For example, in the RMC-DTS one jaw is smooth. Quick adjustable stopper plate PBQ-S1 This “speed plate” option for B-size. It replaces the one stopper module, and works with all B-size clamps Please note this module holds a clamping force in one direction only. OK-VISE® Multi-Rail RM System

Quick adjustable stopper plate PDQ-S1 This “speed plate” option enables users of Multi-Rail RM to move clamp modules on the rail into a different position in just a few seconds. It also replaces one stopper module, and works with RMC-DS and RMC-DR. Please notice this module holds clamping force in one direction only. RMRC-28 This riser block lifts up RM clamp 28 mm. This is designed to be used with D-series clamps, and a longer M12 bolt and T-nut are included. Can also be used as a rotation stop module. OK-VISE® Multi-Rail RM System

RMS-S The most common stopper is RMS-S, which has two smooth and nitrided jaws. It is optimal for the second setup, when OK-VISE clamps are used with full force. Friction level is adequate even for roughing and other types of machining where high forces occur. The accuracy from every serration to the jaw surface is ± 0.01 mm. RMS-S2 RMS-S2 is more narrow than RMS-S, about the size of a B-series clamp. OK-VISE® Multi-Rail RM System

OK'VISE Fixturing Concept RMS-S3 is used often with D-series double-wedge clamps. Also, when used in tooling blocks higher stopper can make workpiece loading easier. This stopper type has a serrated contact area on both sides of the stop module. The contact area is nitrided. One popular variation is a stopper RMS-SR2 which has one serrated (R2) and one smooth (S) jaw. OK-VISE® Multi-Rail RM System C07092021 16.9.2021 11

OK'VISE Fixturing Concept RMS-G is a grip model with two HSS pins that penetrate into the workpiece, leaving tiny marks on it. The friction is much higher than that of using the standard serrated jaw, against soft steel the friction co-efficient factor is up to 0,8. Model RMS-GS has one grip jaw and one smooth jaw.

OK'VISE Fixturing Concept In this stopper module the same additional pieces can be used as in D-series low-profile clamps. In this stopper module the same additional pieces can be used as in D-series low-profile clamps. RMS-T has two additional pieces jaws. For example RMS-TS is a stop module which has one smooth jaw and one additional piece jaw. This serrated riser block lifts up RM stopper 28 mm, RM serration is both at the bottom and the top of the block. Additional RM T-nut and longer bolt are included, so stoppers like RMS-S, RMS-R etc. will work directly on this riser block. You can use...

RMS-V, RMS-Vx This model has a vertical V-shape jaw to hold round-shaped workpieces of various sizes. The optimal workpiece sizes are given in the Dimension drawings (see Dim. in the table above). Please note that when machining a workpiece with a diameter larger than maximum given in the Dimensions drawings, there is a line contact between the jaw and the workpiece, and the jaw is likely to leave marks on the workpiece surface. RMS-V has two such jaws, RMS-VS has one smooth jaw (photo). RMP-1 RMP-1 is the most common parallel model. OK-VISE® Multi-Rail RM System
