Šiame straipsnyje apžvelgiama, kaip tinkamai naudoti Dremel įrankį su medienos disko laikikliu, įskaitant saugumo aspektus, įrankio parinkimą, greičio nustatymus, šlifavimą, pjovimą ir poliravimą. Pateikiami praktiniai patarimai, siekiant užtikrinti kokybišką darbą ir išvengti žalos įrankiui bei medžiagai.
Saugumas ir parengiamieji veiksmai
Safety glasses, found in the PPE drawer, must be worn during operation. The Dremel is intended to be used only as a grinder, sander, wire brush, polishing tool, carving tool, or cut-off tool. Use only the attachments included in this kit. Do not use any damaged accessory. With the shaft lock engaged, twist and use the collet wrench to loosen the collet nut if necessary. The collet nut must be loosely threaded on when inserting an accessory. Change accessories by inserting the new one into the collet as far as possible to minimize runout and unbalance.
With the shaft lock engaged, finger tighten the collet nut until the accessory shank is gripped by the collet. For precision work, it is important that all accessories be in good balance. Practice first on a piece of scrap material to get a feel for the weight and speed of the Dremel before beginning your project. The Dremel may jump back when it makes contact with an object; this is normal and can be controlled by holding it firmly.
Įrankio parinkimas ir tvirtinimas
Collets are used to hold Dremel attachments in place. The collet's size can be identified by the number of rings at the base and should match the size of the corresponding attachment. The attachment should fit all the way into the collet; if it doesn’t fit all the way, it’s too small. Different size collets (see illustration), to accommodate different shank sizes, are available for the Dremel. To install a different collet, remove the collet nut and remove the old collet. Insert the unslotted end of the collet in the hole in the end of the tool shaft. Always use the collet which matches the shank size of the accessory you plan to use. For precision work, it is important that all accessories be in good balance.

To true up or balance an accessory, slightly loosen collet nut and give the accessory or collet a ¼ turn. Retighten collet nut and run the Rotary Tool. You should be able to tell by the sound and feel if your accessory is running in balance. Always hold the tool away from your face. Accessories can be damaged during handling and can fly apart as they come up to speed. Concentrate on guiding the tool over the work using very little pressure from your hand. The object you are working on must be either firmly held in hand or clamped to a surface. Usually, it is best to make a series of passes with the tool rather than attempt to do all the work in one pass.
- To make a cut, for example, pass the tool back and forth over the work, much as you would a small paint brush. Cut a little material on each pass until you reach the desired depth.
- For most work, the gentle touch is best.
Greitis, lengvumas ir įrankių derinimas
The Dremel may be used at varying speeds. The variable speed dial allows adjustments according to material. Certain materials, however, (some plastics and metals, for example) require a relatively slow speed because at high speed the friction of the accessory generates heat and may cause damage to the material. Slow speeds (15,000 RPM or less) usually are best for polishing operations employing the felt polishing accessories. They may also be best for working on delicate projects such as delicate wood carving and fragile model parts.
The best way to determine the correct speed for work on any material is to practice for a few minutes on a piece of scrap, even after referring to the chart. You can quickly learn that a slower or faster speed is more effective just by observing what happens as you make a pass or two at different speeds. When working with plastic, for example, start at a slow rate of speed and increase the speed until you observe that the plastic is melting at the point of contact. Iron or steel should be cut at high speed.

To install a different collet, remove the collet nut and remove the old collet. Insert the unslotted end of the collet in the hole in the end of the tool shaft. The Dremel is equipped with a variable speed dial. Change accessories by inserting the new one into the collet as far as possible to minimize runout and unbalance. Bristle brushes are good for general purpose cleaning. They should be used at speeds no greater 15,000 RPM. Avoid using pressure, as it can cause the wires to break and fly out. A mandrel is a shank with a threaded or screw head, which are required when you use polishing accessories, cutting wheels, sanding discs, and polishing points. The Small Screw Mandrel is used by unscrewing the top screw, placing the screw through the desired attachment, and returning the screw into the mandrel hole.

Attachment heads can be added to the EZ Lock by lining up the notches, pushing the gray plastic down, and twisting until securely locked. For cutting circles in material, use appropriate circle-cutting techniques and ensure material is securely clamped. When cutting, pass the tool back and forth over the work, gradually increasing depth while keeping kontaktas švelnus.
Praktiniai patarimai darbui su mediena
Praktikuokite ant sknapo medžiagos arba lenta, kad įsisavintumėte svorį ir greitį. The work is done by the speed of the tool and by the accessory in the collet. Instead, lower the spinning accessory lightly to the work and allow it to touch the point at which you want cutting to begin. The object you are working on must be firmly held or clamped. For intricate wood carving and fine sanding, use the appropriate accessories and keep a light touch.
