RM stop modules

Code	Dimensions	STEP
RMS-S

The most common stopper is RMS-S, which has two smooth and nitrided jaws. It is optimal for the second setup to avoid marking even 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 serrration 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.

RMS-S3

RMS-S3 is used often with D-series double-wedge clamps. Also, when used in tooling blocks higher stopper can make workpiece loading easier.

RMS-SR2

This stopper has one jaw that is serrated ( like in RMS-R2) and the other is smooth.

RMS-R2

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.

RMS-G4S

RMS-G4S is a grip model, one jaw possessing a knife-edge grip pattern while the other jaw is smooth. The jaws are nitrided.

RMS-G
RMS-GS

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.

RMS-G4 is a grip model, where both jaws posses a knife-edge grip pattern. The jaws are nitrided.

RMS-M
RMS-MS

RMS-MSThese are machinable stopper models which are especially suitable for machining of complex workpieces, or when extreme accuracy is needed and product-specific jaws are used for machining.

RMS-M has two extended jaws that are machinable. Furthermore, all combinations can be machined because these models are made of the relatively soft material (HRC 30, not hardened or nitrided). In the RMS-MS model, one jaw is of  the "normal" length, and normally it is smooth. For machining purposes this model is slightly bigger in size.

Also many other variants of combinations can be made, so "x" can be =R (serrated), V (vertical slot) etc.

RMS-T
RMS-TS

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.

STEP (3D)

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 the bolt and T-nut form the original stopper in the "front" hole of the riser block.

Additionally, quick setup plate PBQ-S1 and any B-series clamp can be used with the base riser unit.

This stopper type has two round, serrated contact areas which hold both big and small workpieces firmly in the correct position.

 The accuracy from every serrration to the jaw surface is ± 0.25 mm.

RMS-D
RMS-DS

These stopper modules have at least one jaw which is diamond coated (D). In the RMS-D model both jaws have a diamond coating, while RMS-DS has one jaw that is smooth. 

The accuracy from every serrration to the jaw surface is ± 0.25 mm.

RMS-V
RMS-VS

RMS-VSThis 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).

RMS-R64

This stopper type has a serrated contact area on both sides of the stop module. The contact area is nitrided.

The width of the stopper is 64 mm, so this is optimal for first operation of workpieces 66...88 mm wide.

RMS-H
RMS-HS

RMS-H

This model has a horizontal V-shape jaw to hold small round-shaped workpieces or bars. 

RMS-H has two such jaws. In the RMS-HS module one jaw is smooth and another one - V-shape.
