Ce face, mai exact, șurubul de oprire al arcului?

Controlează preîncărcarea arcului intern al mașinii. Prin ajustarea lui modifici forța cu care needle bar-ul revine în poziția retrasă după fiecare penetrare: mai strâns înseamnă forță de retur mai mare (potrivit pentru lining agresiv), mai slăbit înseamnă forță de retur mai mică (potrivit pentru shading delicat). Este un instrument de fine-tuning care nu necesită schimbarea came-ului.

Cum se ajustează corect?

Cu mașina oprită, localizează șurubul și folosește cheia Allen corespunzătoare (piesa nr. 51 din kitul InkMachines). Înșurubează în sens orar pentru mai multă preîncărcare/forță și deșurubează în sens antiorar pentru mai puțină. Fă ajustări mici, de câte un sfert de tur, și testează pe piele artificială. La final verifică dacă setarea se menține după câteva minute de funcționare.

Se uzează piesa și cum îmi dau seama?

Da. Fiind reglată frecvent, filetul se uzează progresiv. Semnele sunt: setarea nu se mai menține în timpul sesiunii (se modifică singură sub vibrații), filetul se rotește fără rezistență sau șurubul oscilează în locaș. La primele semne de pierdere a poziției, înlocuiește-l.

Pot folosi un șurub generic în loc de piesa originală?

Nu este recomandat. Piesa originală (nr. 77) are filetul calibrat specific pentru mașinile InkMachines. Un șurub generic poate avea diferențe subtile care afectează precizia reglajului sau pot deteriora filetul mașinii.

Funcționează cu orice came?

Da. Șurubul ajustează preîncărcarea arcului intern independent de came-ul montat, așa că poți combina orice came cu orice setare a șurubului pentru a obține comportamentul dorit al mașinii.

Câte piese de rezervă îmi recomandați?

1-2 sunt suficiente. Piesa se uzează mai lent decât arcurile, dar mai repede decât componentele structurale, iar o rezervă la îndemână te scapă de situația în care nu mai poți regla mașina din cauza unui filet uzat.

Guide & full description

Complete guide: Inkmachines nr. 77 - Spring stop screw - 1pcs

The spring stop screw (part no. 77) is a precision adjustment component for InkMachines rotary machines. Its role is to limit the extension of the internal spring (inner piston spring) and thus control its preload — that is, the force with which the needle bar returns to the retracted position after each penetration. It is an original spare and fine-tuning part, useful for the tattoo artist who wants to adapt their machine to their own style without changing the cam or other components.

How to use

With the machine turned off and disconnected, locate the spring stop screw on the machine body.
Prepare the appropriate size Allen key (from the InkMachines kit, part no. 51).
For more return force (lining, more aggressive stroke), screw clockwise — you compress the internal spring more and increase the preload.
For a gentler return (shading), unscrew counterclockwise — you reduce the spring preload.
Make small adjustments, quarter turns at a time, and test each time on artificial skin before proceeding further.
After a few minutes of operation, check if the setting has held. If it changes by itself under vibrations, the thread may be worn and the part must be replaced.

Tips from us

Work in small steps (quarter turns) and test between them — fine adjustment is easily lost if you change too much at once.
Note down your preferred setting for each style (lining vs. shading) so you can reproduce it quickly.
Keep 1-2 spare parts in your kit: the screw wears slower than springs but faster than structural components.
You can combine any cam (different strokes) with different settings of this screw to achieve exactly the desired machine behavior.
If you change the internal spring — for example when switching from standard needles to cartridges — redo the screw adjustment, because the reference preload changes.

Warning: Make any adjustments only with the machine turned off and disconnected. It is an internal mechanical part, which does not come into contact with the client's skin, but it is part of a machine that you use in an environment that must be kept clean: keep the machine body sanitized and use protective barriers (film) during work, according to your usual protocol. If the thread no longer holds the set position (turns without resistance or the setting changes by itself under vibrations), replace the part — an unstable adjustment leads to unwanted variations in stroke during the session.

Frequently asked questions

What exactly does the spring stop screw do?▾

It controls the preload of the machine's internal spring. By adjusting it you change the force with which the needle bar returns to the retracted position after each penetration: tighter means higher return force (suitable for aggressive lining), looser means lower return force (suitable for delicate shading). It is a fine-tuning tool that does not require changing the cam.

How to adjust it correctly?▾

With the machine turned off, locate the screw and use the appropriate Allen key (part no. 51 from the InkMachines kit). Screw clockwise for more preload/force and unscrew counterclockwise for less. Make small adjustments, quarter turns, and test on artificial skin. Finally, check if the setting holds after a few minutes of operation.

Does the part wear out and how do I know?▾

Yes. Being adjusted frequently, the thread wears progressively. Signs are: the setting no longer holds during the session (changes by itself under vibrations), the thread turns without resistance, or the screw wobbles in its seat. At the first signs of losing position, replace it.

Can I use a generic screw instead of the original part?▾

It is not recommended. The original part (no. 77) has a thread calibrated specifically for InkMachines machines. A generic screw may have subtle differences that affect adjustment precision or could damage the machine's thread.

Does it work with any cam?▾

Yes. The screw adjusts the internal spring preload independently of the cam installed, so you can combine any cam with any screw setting to achieve the desired machine behavior.

How many spare parts do you recommend?▾

1-2 is enough. The part wears slower than springs but faster than structural components, and having a spare on hand saves you from the situation where you can no longer adjust the machine due to a worn thread.

Product description

Inkmachines nr. 77 - Spring stop screw The InkMachines Spring Stop Screw (part no. 77) is the original spring stop screw for InkMachines rotary machines, a precision adjustment component controlling the extension limit of the internal spring (inner piston spring), indirectly determining the sensitivity and return force of the needle bar. This screw functions as an adjustable mechanical limiter — by screwing in or out, the tattoo artist controls the internal spring preload, thus modifying the force with which the needle bar returns to the retracted position after each penetration. Deeper screwing compresses the spring more, increasing return force (more aggressive, more suitable for lining), while unscrewing reduces preload (more delicate, more suitable for shading). Manufactured from quality steel with precision thread, the spring stop screw allows fine and repeatable adjustments of machine behavior without changing the cam or other components. The precision thread ensures the set position is maintained even under operating vibrations. As an adjustment part subjected to frequent adjustments, the spring stop screw can develop thread wear over the long term, resulting in loss of position-holding ability and unwanted setting changes during sessions. The original InkMachines part (no. 77) guarantees thread compatibility and correct adjustment system behavior. The fine-tuning capability provided by the spring stop screw is one of the distinctive advantages of InkMachines machines over competitors. It allows artists to customize machine behavior for their unique working style, without being limited to fixed configurations. The precision thread of the original InkMachines part (no. 77) ensures fine adjustments and maintenance of the set position even under the intense vibrations of high-RPM operation, an aspect impossible to achieve with a generic screw.
