A sharp decrease in the efficiency of the nail machine when in contact with the nail plate often signals that the cutting edge of the tool has dulled or damaged. At this point, the wizard must immediately stop the device, disconnect it from the network and carry out the procedure of changing the working element so as not to injure the client and not spoil the coverage. The process of replacing the cutter on a nail machine requires an understanding of the type of clamp installed, since inept actions can lead to the breakdown of the tsanga or cartridge.
The safety of the procedure depends on whether the device is completely de-energized before the manipulation. Even if the device is battery-operated and appears to be off, residual charge or accidental pedal pressing can activate the motor, resulting in a finger injury. Therefore, the first step is always to physically disconnect the power cord or remove the battery, if the design of the model provides for it, and only then you can start dismantling consumables.
Incorrect choice of direction of rotation or ignoring the type of tail nozzle are the most common reasons why the tool flies out during operation or gets stuck in the cartridge. Understanding the principle of operation of the tsang mechanism or threaded connection allows you to avoid situations when the master spends time untwistling the jammed nut or repairing the broken hole. In this instruction, we will analyze the technical nuances of replacing nozzles for different types of equipment.
Determination of the type of clamping mechanism of the apparatus
Before you start working, you need to visually and tactilely determine what type of fixation is used in your home. nail-driller. Most modern devices, such as Strong, Marathon or PromaxThey are equipped with a tsang clamp, which does not require the use of additional keys. In such models, fixation occurs due to compression of the tsangi petals when turning the external sleeve.
Older or specialized models may have a screw type of attachment, where the nozzle is fixed by a small screw on the side or front of the cartridge. To work with such devices, you will necessarily need a special hexagon key, which usually comes complete with the device. Attempting to replace the milling cutter in a screw clip without a key can lead to slicing of the screw faces and subsequent inability to remove the tool.
⚠️ Warning: Never try to replace a milling cutter while the machine is plugged in or the power indicator is on, even if the pedal is not pressed. A random surge in voltage can start the motor.
There are also devices with an automatic change system, where it is enough to simply insert a tailing before clicking to fix, but such models are less common and require specific attachments. It is important to carefully examine the nose of the handpiece to find the locking screw or to understand whether the outer part is a rotating bushing. The next algorithm of actions depends on this.
Preparation of the workplace and tools
The organization of space plays a key role in the speed and safety of the procedure. You will need a clean, well-lit surface, free of unnecessary items, so as not to lose small details such as lock screws or tsang caps. It is recommended to use a special manicure mat with sideways, which will prevent falling and loss. cutter In case it slips out of your fingers.
If your machine is equipped with a screw clip, find the complete key and make sure it fits in size. For tsang mechanisms, no additional tools are needed, but hands must be dry and clean to ensure a reliable grip. Fatty from cream or oil can cause the fingers to slip off the smooth surface of the bushing, which is especially critical if the tsanga is tightly clamped.
Prepare a new nozzle and container for used tools in advance, so as not to confuse clean and dirty consumables. Storing sharp and cutting objects in a common pile can lead to damage to new milling cutters or injuries when finding the right size. It is logical to decompose everything necessary in order of use: first, the tool for opening, then a new milling cutter, then the container for the old one.
☑️ Ready to replace cutters
The algorithm of the milling cutter replacement in the tsang clamping
The tango mechanism is the most common in the nail service industry due to its reliability and ease of operation. To replace the milling cutter, with one hand firmly grasp the handle of the apparatus (hand-piece), fixing it in a stationary position. With the second hand, grab the grooved bushing (the cylinder in the nose) and start turning it counterclockwise.
At the time of turning, you will hear a characteristic click, and the inner tsang will unwind, freeing the tail of the cutter. If the cutter does not fall out on its own, carefully remove it with your fingers, trying not to touch the cutting part, which may be hot after work. Insert the new nozzle into the hole to the point, but without excessive pressure, and twist the bushing clockwise until reliable fixation.
It is important not to drag the sleeve, as this can lead to deformation of the tsanga and difficulties with the next replacement. It is enough to feel the confident resistance of the mechanism. After installation, be sure to check the reliability of the mounting, slightly pulling the milling cutter down - it should not stagger or fall out with a light shake of the device.
What to do if the tsanga is scrolling?
If when turning the sleeve it scrolls, but the cutter does not come out, it is possible that the tsanga is contaminated with dust or jammed. Drop a drop of oil for the equipment and try several times to open and close the clip without a cutter. If this does not help, you may need to disassemble the hand-piece specialist.
Replacement of the nozzle in the machine with a screw clip
Models with screw fixation require a more delicate approach and the presence of a special key. Find on the case of the handle a small hole with a screw, which rests on the tail of the cutter. Insert the key into the screw head and turn it counterclockwise, loosening the clamp. Do not twist the screw completely, so as not to lose it, it is enough to free up space for the outlet of the cutter.
After weakening the screw, the cutter should be easily removed. If it is stuck, do not use force and do not try to knock it out, as it can damage the inner surface of the cartridge. Carefully swing the nozzle from side to side, helping it to go out. Insert a new milling cutter, making sure it has entered to the end, and tighten the locking screw clockwise with moderate effort.
Control the tightening force: too weak a screw will lead to the loss of a cutter during operation at high speeds, and too tight can tear the thread or damage the tailing of the nozzle. Optimal is considered to be the force at which the milling is securely fixed, but the screw does not require the use of excessive force for twisting.
Table of compatibility and parameters of tailings
When choosing new consumables, it is critically important to pay attention to the diameter of the tailing, since incompatibility can lead to breakage of the device or poor-quality work. Standards may vary depending on the manufacturer and type of equipment, so checking the parameters before buying is mandatory.
| Type of apparatus | Tailor diameter | Type of clamping. | Note |
|---|---|---|---|
| Professional (Strong, Marathon) | 2.35 mm | tango | Standard of industry |
| Household/Compact | 3.0 mm | Tsang/Spinning | Frequently found in sets |
| Pedicure powerful | 6.0 mm | Screw/Tsang | For rough handling |
| Micro-drills (for details) | 1.0 - 1.5 mm | tango | Specific application |
The use of cutters with a smaller diameter of the tail in a larger cartridge is impossible without special adapters that reduce the accuracy of the beating. Attempt to insert a nozzle with a large diameter force will lead to irreversible expansion of the tsang and failure of the handle. Always check the marking on the packaging of the nozzle with your technical passport. nail-driller.
The main rule: The diameter of the cutter tail should exactly correspond to the diameter of the tsang of your device. The use of adapters is allowed only in extreme cases and reduces the quality of work.
Typical errors and troubleshooting
One of the most common mistakes is to install the cutter not to the point. If there is a gap between the end of the tail and the bottom of the tsanga, when working at high revs, a strong vibration and beat occurs. This not only reduces the quality of nail processing, but also creates a load on the bearings of the engine, reducing the service life of the device.
Another common problem is contamination of tsanga with nail dust. Fine dust penetrates into the mechanism and, mixing with oil, forms an abrasive paste, which prevents the normal compression of the petals. Regular purge of the cartridge with compressed air or the use of special cleaning products helps to avoid jamming.
⚠️ Warning: If after replacing the cutter, the machine makes an extraneous noise or whistle, turn it off immediately. This may indicate skewed nozzles or damage to bearings.
Also, the masters often forget to check the direction of rotation before starting work. Different types of milling cutters (ceramics, solid alloy) may require different rotation direction (Forward/Reverse). Installation of a milling cutter designed for rotation clockwise, when the reverse is turned on, will make the work inefficient and dangerous.
Useful advice: wipe the tail of the new cutter with an alcohol napkin before installation. This will remove the factory lubricant and provide a more reliable grip on the tsanga, eliminating slippage.
Caring for the cartridge and prevention
Regular maintenance of the clamping mechanism prolongs the life of expensive equipment. After each working day, it is recommended to conduct a visual inspection of tsanga for the presence of chips or dust. For cleaning, you can use a special brush that is included in the kit, or gently blow the hole.
Once a month, depending on the intensity of the load, it is useful to conduct a deeper cleaning. To do this, in a fully compressed tsanga (without a cutter), you can drop one drop of special oil for equipment and turn the bushing several times. This will wash away the contamination and lubricate the rubbing surfaces, preventing corrosion and jamming.
Keep the device in a dry place, preferably in a case or on a stand, so that the dust does not settle in an open cartridge. Careful attitude to the mechanism of replacing the cutter ensures that at a critical moment the client does not have to wait until the master copes with the stung nozzle.
What to do if the cutter is stuck and not removed?
If the cutter is jammed, try to slightly tap the handle of the apparatus (carefully!) on the palm of the other hand to loosen the mechanism. You can also try to heat the nose with a hairdryer (without overheating!) to expand the metal, but this method is risky. The best solution is to contact the service center so as not to break the tsanga completely.
Can I use conventional medical borons in a manicure machine?
Yes, if the diameter of the boron tailing is the same as the diameter of the tsang of your device (usually 2.35 mm). However, medical borons often have a lower alloy hardness and are more quickly dulled when working with artificial materials (acrylic, gel).
How often do you need to change the cutters?
The frequency of replacement depends on the material of the cutter and the amount of work. Hard alloy cutters serve longer than ceramic cutters. Signs of dullness: the device begins to “chew” the material, there is a strong heating, the speed of sawing decreases, the client feels vibration and discomfort.
