Compensating holderDAH TM 50 HS

Dihart ® DAH 50 HS compensating holders –for maximum precision and concentricityThe new Dihart DAH 50 HS compensating holders ensure that the tool runs concentrically.They allow precision adjustment of the tool in the µm range at the cutter eliminating anymachine spindle error. Maximum concentricity guarantees reliable production within extremelyclose tolerances. The quality of the bore, including surface quality, circularity, roundnessand parallelism and above all the dimensional accuracy are improved considerably.This significantly increases the process reliability with Dihart multiple blade reamers.Proven hydro-expansion clampingwith new highlightMaximum concentricity and repetition accuracy< 1 µm for uniform blade contactExtremely simple concentricity adjustmentCompact designOptimum vibration damping for excellent surfacequalityFlexible clamping range with reduction sleevesSpeeds up to 25,000 rpmFor minimal lubrication (MLC)Flexible clampingrange withadapter sleevesSimple handling –reduced machine idle timesAdapter sleeves allowone Dihart hydro-expansioncompensating holder to beused for different shankdiameters.In comparison to previous solutions the hydro-expansionchuck is integrated into thenew Dihart compensating holders. This meansone less interface. Four adjustable screws allowrapid and precise adjustment of the concentricityof the multiple blade reamer, reducingconcentricity errors to virtually zero. Theextremely slim design of these new compensatingholders ensures that they fit easily intopractically all tool magazines.Alignment module:1 Adjustment ring4 Adjustment screwsSimple, time-saving control using adjustmentring with adjustment screw.Tightening screwfor clamping toolAdjustment of concentricityon cutter tovirtually „zero“ µmConnection on tool-sidewith expansion chuckConnection on machine side:SK 40; HSK 3

High speed machining –with maximum qualityWith the new Dihart DAH 50 HS compensating holders you can easily perform high speedmachining at speeds up to 25,000 RPM. Extremely high speeds are possible even with smallPCD tools.Applications for Dihart toolsREAMAXMONOMAXPCD standard lineVHM lineDihart special toolsBore dia.
