Drill bushes from SCHOLZ MECHANIK are used in all manufacturing companies as a cost-effective and wear-resistant component. No longer just for precise drill guidance, but also in combination with new production processes - e.g. 3D printing - the drill bush can be used to quickly produce clamping fixtures, measuring gauges, clamping supports, etc.Drill positioning bushes are important and useful elements for placement and grid plates for turning and milling centres. Their high hardness and tight tolerances ensure very high repeat accuracy and a long service life.Assembly:the drill diameter should correspond to the bushing diameter,press in the bushing angular with a flat mandrel or drive in with Soft-face mallet SM 3366A.

The positioning bushings SM 1273-54 and SM 1273-55 with conical bore are used forthe detent bore of indexing plungers SM 1273-51 and allow precise positioning.The length l7 of the indexing pin is determined by the depth of penetration of the indexingpin into the cone of the bushing. The length l8 must ensure complete disengagement of the indexing pin. When engaged, the pin must have at least 0.5 mm residual stroke so that the conical part of the pin is seated in the cone of the positioning bush without play.To accommodate the positioning bushings (outer Ø with tolerance n6), the locating holes hould have tolerance H7.

Indexing plunger for screwing on, plunger pin conicalfor precision locating
Material:steel, blackenedplunger: hardened and groundknob: black plastic (Polyamide PA), matt finish, not removable
Form B: without rest positionForm C: with rest position, knob is turned 90°
Indexing plungers SM 1273-51, together with guide bushings SM 1002 and SM 1273-55 /sim. to DIN 172 and SM 1002 or SM 1273-54 / sim. to DIN 179 enable precise positioning.The bushings are used to guide the plunger pin as well as for the indexing bore. Larger guide lengths further increase the precision.Two different plunger pin lengths l1 are available for each indexing plunger diameter d1.The length l7 is determined by the penetration depth of the plunger pin into the cone of the bushing. The length l8 must ensure that the plunger pin fully disengages, bushing length and plate thickness plus any gap can then be selected within certain margins.If engaged, the pin must have a minimum remaining stroke of 0,5 mm to make sure that the conical section of the pin is located without clearance in the cone of the guide bushing. For a safe remaining stroke length: l9 = l1 - 0,5 mm.To accommodate the positioning bushings (outer Ø with tolerance n6), a locating holewith tolerance H7 is usually provided.
Type C is used for such applications where the plunger has to stay in its retracted position.To achieve this, the knob is rotated by 90° degrees after being retracted.A notch keeps the plunger in this position.
RoHS-compliant: yes
