4INTERESTING HINTS FOR TAPPING

HINWEISE ZUM GEWINDESCHNEIDEN

Optimum tapping conditions reduce effective machining times and increase tap life.

Optimale Bedingungen beim Gewindeschneiden reduzieren die Maschinenhauptzeiten und erhöhen die Standzeit.

Which types of tap or whether or not a thread former can be used, depends on the type of material to be machined.

As a general guide, materials with an extension of at least 10% can be cold-formed.

To determine the most suitable tap, refer to the tap recommendation table on pages 356 to 363.

Welcher Typ Gewindebohrer oder ob ein Gewindeformer eingesetzt werden kann, hängt von dem zu bearbeitenden

Werkstoff ab.

Als allgemeiner Leitwert gilt, daß Werkstoffe mit mindestens 10% Dehnung kaltgeformt werden können.

Zur Bestimmung des optimalen Gewindebohrers nutzen Sie die Empfehlungstabelle auf den Seiten 356 bis 363.

Selection of the most suitable tap

Auswahl des geeigneten Gewindebohrers

- Core holes should be clean and swarf-free.

- Core holes should be of the prescribed size, see chart extract on page 583-584 of this catalogue, and dependent on

the actual application, selected towards the upper diameter limit.

- Kernlöcher sollten sauber und spanfrei sein.

- Kernlöcher sollten die angegebenen Durchmesser haben, siehe Seiten 583 und 584, und abhängig vom aktuellen

Einsatzfall, zur größtmöglichen Durchmesserangabe tendieren.

Core holes

Kernlöcher

Frequently the coolants used on machining centers are unsatisfactory for tapping because their percentage lubricant

content is too low. If it is not possible to increase the percentage of lubricant in the emulsion, the lubrification problem

can be solved in other ways, i.e.:

Meistens sind die gebräuchlichen Kühlmittel in Bearbeitungszentren zum Gewindeschneiden nicht geeignet, weil ihr

Anteil an Schmierstoffen zu gering ist. Wenn es nicht möglich ist, den Anteil an Schmierstoffen in der Emulsion zu

erhöhen, kann das Schmierproblem in anderer Weise gelöst werden, z. B.:

Lubricating with concentrated emulsion Schmierung mit konzentrierter Emulsion

A. A Iubricating unit, connected to the machine control, delivers at the required instant a specific quantity of

concentrated emulsion into the core hole or onto the tap.

B. A pump in a separate tank, controlled by the machine, delivers a specific amount of concentrate into the core hole.

A. Eine Schmiervorrichtung, die mit der Maschinensteuerung verbunden ist, gibt zum gewünschten Zeitpunkt eine

bestimmte Menge konzentrierter Emulsion in das Kernloch oder auf den Gewindebohrer ab.

B. Eine Pumpe mit separatem Tank, mit der Maschinensteuerung verbunden, gibt eine bestimmte Menge des

Konzentrats in das Kernloch

Tapping in separate operations Gewindeschneiden als separater Bearbeitungsgang

This procedure allows the use of the ideal tapping lubricant.

Dies erlaubt den Einsatz des idealen Gewindeschneid Schmiermittels.

Lubricant in relation to machining centers

Schmiermitteleinsatz auf Bearbeitungszentren

The cutting speed has a great influence on chip flow and the life of the tap.

It is worthwhile to establish the ideal cutting speed by tapping trials.

Guide values see on the recommendation table page 364. The cutting speed should be in relation to the characteristics

of the material, the machine and its equipment.

Die Schnittgeschwindigkeit hat großen Einfluss auf den Spanabgang und die Lebensdauer des Gewindebohrers.

Bei Großserien ist es lohnend, die ideale Schnittgeschwindigkeit durch Versuche zu ermitteln.

Leitwerte finden Sie in der Empfehlungstabelle Seite 364. Die Schnittgeschwindigkeit sollte auf den Werkstoff, die

Maschine und das Umfeld abgestimmt sein.

Effects of unsuitable cutting speed Die Folgen falscher Schnittgeschwindigkeiten

- forced tapping Zu hoher Kraftaufwand

- tap lead chipping caused by overloaded cutting tooth Beschädigte Steigung durch überlastete Schneide

- torn threads Verschnittenes Gewinde

- unsatisfactory tap-life Ungenügende Standzeit

- rejected threads Ausschuss

What are the causes of cold welding? Was sind die Gründe für eine Kaltaufschweißung?

- unsuitable tap selection Ungeeignete Gewindebohrer Auswahl

- tap with incorrect cutting geometry Gewindebohrer mit falscher Schneidengeometrie

- coolant unsuitable for material Kühlmittel ungeeignet für den Werkstoff

- insufficient coolant Unzureichende Kühlung

- axial pressure (pull or push) on the tap Axialer Druck (Zug oder Druck) auf den Gewindebohrer

- core hole too small Kernloch zu klein

- breaks in walls of core hole Risse in der Wand des Kernlochs

- speed too high or too low Schnittgeschwindigkeit zu hoch oder zu klein

- swarf trapped in the hole Verklemmter Span im Kernloch

- incorrect alignment of tap and core hole Achsversatz zwischen Gewindebohrer und Kernloch

- tap eccentricity Gewindebohrer läuft unrun

Effects of cold welding: Die Folgen von Kaltaufschweißungen

- torn threads verschnittene Gewinde

- short tap life kurze Standzeit

- rejected threads Ausschuss

- tap breakage Werkzeugbruch

- scrap workpieces schrottreife Werkstücke

Cold welding

Kaltaufschweißung

- The tap must be mounted on the axis of the core hole.

- On non-synchronized machines (feed / speed) we recommend the use of a tapping spindle.

- Die Achsen von Gewindebohrer und Kernloch müssen genau fluchten.

- Auf nicht synchronisierten Maschinen (Vorschub / Schnittgeschwindigkeit) empfehlen wir den Einsatz einer

Gewindeschneidspindel.

Tap mounting

Gewindebohrer einspannen

With non-synchronized machine spindles (feed / speed) the feed rate should as a rule be programmed approx. 5-

10% lower than the thread pitch. In these cases a tapping chuck must be used which will compensate the

difference between the feed rate and the thread pitch.

It is important that the tension spring in the axial compensation is set to a light rate to avoid axially loading the tap.

The compression spring should be tensioned so that the tap starts to cut by compressing the spring at the most up

to one half pitch.

Bei nicht synchronisierten Maschinenspindeln (Vorschub / Schnittgeschwindigkeit) sollte der Vorschub in der Regel

5 – 10% kleiner sein als die Gewindesteigung. In diesen Fällen muss ein

Gewindeschneidfutter verwendet werden, das die Differenz zwischen dem Vorschub und der Gewindesteigung

ausgleicht.

Es ist wichtig, daß die Spannfeder im axialen Ausgleich locker eingestellt wird, um eine zu große axiale Belastung

des Gewindebohrers zu vermeiden.

Die Druckfeder sollte so gespannt sein, daß der Gewindebohrer zu schneiden beginnt, wenn die Feder bei

höchstens einer halben Steigung gespannt ist.

Important hints: Wichtige Hinweise :

Ensure that the correct speed is selected.

Ensure that ample lubricating coolant is used when tapping.

Good machine and equipment stability is essential for optimum quality and performance.

Sorgen Sie für die richtige Schnittgeschwindigkeit.

Sorgen Sie dafür, daß reichlich Kühlschmiermittel beim Gewindeschneiden verwendet wird.

Gute Stabilität von Maschine und Vorrichtungen ist die Grundlage für optimale Qualität und Leistung.

6RESHARPENING

NACHSCHARFEN

The resharpening on taps is done for regenerating the active

hedges weared by the destructive action of cutting and of friction, it

has high importance for an economical exploitation of the tool and so far has

to be made rationally, keeping away from wrong operations

which can heavily compromise the accuracy and the life.

In order to execute the tap resharpening quickly and accurately

we recommend the use of proper resharpening machines having

all necessary equipments for this operation.

The tap resharpening take place in two steps:

a) resharpening of (relieved) chamfer;

b) resharpening of flutes. (See picture 1)

Das Nachscharfen der Gewindebohrer dient der Erneuerung der verschlissenen

Schneidkanten.

Es ist wichtig, um das Leistungsvermogen des Werkzeugs voll auszuschopfen

und muss daher prazise durchgefuhrt werden, um Fehler zu vermeiden,

die die Prazision des Gewindes und die Standzeit beeintrachtigen.

Um das Nachscharfen schnell und prazise durchzufuhren,

empfehlen wir den Einsatz von geeigneten Schleifmaschinen

mit dem notwendigen Zubehor.

Das Nachscharfen der Gewindebohrer erfolgt in zwei Stufen :

a) scharfen der Freiflachen im Anschnitt;

b) scharfen der Nuten (Spanflache) (siehe Abb. 1)

RESHARPENING OF (RELIEVED) CHAMFER

RESHARPENING OF (RELIEVED) CHAMFER

The chamfer resharpening must be executed both on specific for taps

machines or on conventional resharpening machines equipped with

an auxiliary system proper to generate the circular relief on back.

The picture 2 shows the resharpening made with

the cylindrical surface of a grinding wheel.

Before resharpening, verify that the tap, fixed between points or on pincer,

runs concentrical; verify also the angle βwhich has to be correct in

order to keep the same number of threads on chamfer.

Das Scharfen des Anschnitts muss entweder auf besonderen

Gewindeschleifmaschinen erfolgen, oder auf konventionellen Schleifmaschinen

mit entsprechenden Vorrichtungen fur einen genauen Hinterschliff.

Abb. 2 zeigt das Nachscharfen mit einer zylindrischen Schleifscheibe.

Vor dem Schleifen uberprufen, ob der Gewindebohrer,

zwischen Spitzen oder in einer Spannzange gehalten, rund lauft;

prufen Sie auch den Winkel b, der korrekt sein muss,

um die gleiche Anzahl Gange im Anschnitt zu haben

RESHARPENING OF FLUTES

NACHSCHARFEN DER NUTEN

This operation must be done on a specific

resharpening machine for taps, equipped with:

deviding head, lead screw of “barrasinus”for executing the helix

and cooling equipment.

The rake angle γis obtained moving the tap axis,

in relation to the resharpening surface,

of an amount X to be calculated with the

formula: X = ½ d1sin γ(see picture 3).

(d1=tap major diameter)

Dieser Arbeitsgang muss auf einer speziellen Gewindebohrer ?

Schleifmaschine erfolgen, die ausgerustet ist mit :

Teilkopf, Leitspindel zum Schleifen entlang gedrallter Nuten und

Kuhlmittelversorgung. Den Spanwinkel g bei Gewindebohrern

mit geraden Nuten erhalt man durch Verstellen der Bohrerachse im

Verhaltnis zu der zu schleifenden Oberflache um den

Einstellwert X, der nach folgender Formel errechnet wird :

X = ? d1 sin g (siehe Abb. 3).

(d1 = Gewindebohrerdurchmesser)

Example:

Tap 10 × 1,5 to cut on steel strength = 600 N/mm2

CARBIDE

On all taps having spiral-flutes, in addition to

the trade mark and identification of the

dimension and type, it is possible to find also

the pitch of the spiral refered to the lead screw

necessary for the resharpening.

In case of employment of taps equipped with

deburring tool Burr-Bit it is necessary to

extend the flutes following what suggested by

the supplier.

Because the wear on a tap is mainly on the

chamfer area, on taps having “gun nose”the

resharpening of the flutes can be made on the

front area only (see picture 4).

Bei allen Gewindebohrern mit gedrallten

Nuten werden allgemein spezielle Schleifmaschinen

eingesetzt, die die Drallsteigung messen

und selbstandig einstellen konnen.

Beim Einsatz von Gewindebohrern mit dem

Entgratwerkzeug Burr-Bit ist es notwenig, die

Nuten entsprechend den Vorgaben des

Herstellers zu verlangern.

Da der Verschleiß eines Gewindebohrers hauptsachlich im

Anschnitt und dem erstenvollen Gewindezahn liegt,

konnen Gewindebohrer mit Schalanschnitt und gerader

Nute auch nur im vorderen

Gewindeteil nachgeschliffen werden (siehe Abb. 4).

It is very important to pay attention that, when

also the thread flanks are worn(in addition to

the active heges) the resharpening as above

described is practically useless.

In this case the “regeneration”is made, by

means of cutting completely the chamfer

away(this means a shorter tap) and reproducing

then the chamfer with same angle and relief.

(see picture 5)

The regeneration is also advisable on taps with

spiral flutes, because that way the flutes

grinding is not necessary, in absence of special

resharpening machines with lead screw with

proper angle.

Es ist wichtig zu wissen, daß beim Verschleiß

der Gewindezahnflanken (zusatzlich zur

Hauptschneidenkante) das oben beschriebene

Nachschleifen praktisch nutzlos ist !

In diesem Fall wird die ?Erneuerung“ dadurch erreicht,

daß der Anschnitt komplett abgetrennt wird

( das bedeutet eine Kurzung des Gewindebohrers

und Verlust der entrierung ) und neu angeschliffen wird,

mit gleichen Winkeln und Hinterschliff (siehe Abb. 5).

Diese ?Erneuerung“ ist auch fur drallgenutete

Gewindebohrer zu empfehlen, weil dann das

Nutenschleifen entfallt, wenn keine geeignete

Schleifmaschine mit Leitspindel vorhanden ist

RESHARPEN TIMELY

RECHTZEITIGES NACHSCHARFEN

It is important to resharpen timely the weared tap. In these conditions in fact

defective threads can be produced, risking to brake the tool;in addition the

wear is increasing quickly, damaging a wide area of the cutter and rapidly.

Es ist wichtig, den Gewindebohrer rechtzeitig nachzuscharfen.

Stumpfe Gewindebohrer konnen defekte Gewinde schneiden,

die Bruchgefahr ist erhoht; zudem nimmt der Verschleiß

schnell zu und zerstort weite Bereiche der Schneiden

PROPER GRINDING WHEELS

RICHTIGE SCHLEIFSCHEIBEN

The structure and grain of grinding wheels must be the right one for

the tap to be resharpened. Our technicians are at complete disposal

to give the proper recommendations.

Bindung und Korn der Schleifscheiben mussen auf die

Gewindebohrer abgestimmt sein.

Unsere Techniker sind bereit, Ihnen die geeignete Empfehlung zu geben

TAPS FOR CAST IRONS

GEWINDEBOHRER FUR GUSS

On these taps the resharpening is rarely possible because,

due to cast iron is abrasive, the tap is wearing on flank of the thread

and so far out of tolerance.

Bei diesen Gewindebohrern ist Nachscharfen kaum moglich. Der verschleißfordernde

Guss greift die Schneidenflanken an, wodurch die Toleranz verloren geht.

TAPS FOR ALUMINIUM

GEWINDEBOHRER FUR ALUMINIUM

It is advisable, after resharpening as above described,

to remove steel burrs from the grinding wheel action.

This operation, easy with iron brushes, avoid the danger of boring or over

tolerance tapping instead of accurate tapping.

Es ist empfehlenswert nach dem oben beschriebenen Nachscharfen

Schleifgrate vom Gewindebohrer mit Stahlbursten zu entfernen.

Dadurch wird die Gefahr vermieden, Gewinde zu groß zu schneiden.

CONTROLS (TESTS)

KONTROLLEN (TESTS)

Once resharpened the tap, it is always better to make some tests to obtain

correct threads same as when the tap was new.

- The chamfer must be perfectly on axis to avoid the

effects of picture 6.

- The cutters must have correct divisions. The results

of a resharpening with a wrong division is shown

on picture 7.

- The length and number of threads on chamfer must

be rigorously identical to those of the new tap.

Nach dem Nachscharfen sollte der Gewindebohrer genau

kontrolliert werden um sicher zu stellen, daß er genauso gut schneidet,

wie ein neuer Bohrer.

- Der Anschnitt muss genau axial sein, um den Effekt wie in Abb.

7 zu vermeiden.

- Die Schneiden mussen eine genaue Teilung haben. Das Ergebnis des

Nachschleifens mit falscher Teilung ist in Abb. 7 zu sehen.

- Die Lange und Anzahl der Gewindegange im Anschnitt muss absolut

genau so sein, wie bei einem neuen Gewindebohrer.
