OBRADA BLOKA MOTORA

Najsavremenije mašine izdvajaju nas od konkurencije. Naš mašinski park sastoji se od mašina koje prate najnaprednije tehnologije obrade, a u velikom broju to su mašine američkog proizvođača Rottler.

Šta je blok motora i koja je njegova uloga?

Blok motora je osnova svakog motora. To je najveći i uglavnom najteži deo motora. U njemu su smešteni radilica (kolenasto vratilo), klipovi sa klipnim prstenovima (karikama), klipnjače i ostali neophodni delovi. Na njemu se nalaze nosači motora preko kojih se motor pričvršćuje za vozilo. Može se reći da je blok motora temelj, za koji se montiraju ostali delova motora.

Prema rasporedu cilindara u bloku, motori se dele na linijske motore, V-motore i boxer motore.

Prema načinu hlađenja, motori se dele na motore za vazdušnim, vodenim hlađenjem, motore koji se hlade uljem…

Blokovi motora se izrađuju od aluminijuma (njegovih legura), livenog gvožđa, (sivi liv) ili legura gvožđa i drugih metala (nikl, hrom).

Kako dolazi do havarije i kako se ona rešava?

Do havarije u bloku motora dolazi usled lošeg podmazivanja motora, pregrevanja motora, prodiranja rashladne tečnosti u cilindre ili ugrizgavanja veće količine goriva u cilindre. Loše podmazivanje motora uglavnom dovodi do ribanja radilice u svojim ležištima i klipova u cilindrima. Kod prodiranja rashladne tečnosti u cilindre ili ubrizgavanja veće količine goriva. Može doći do topljenja klipova, lomljenja klipnjača.

U zavisnosti od stepena kao i specifičnosti oštećenja, sledeće operacije su Vam na raspolaganju:

Dostupne operacije su:

  • Razbušivanje cilindara
  • Ugradnja košuljica (hilznovanje)
  • Razbušivanje kućišta radilice (trnovanje)
  • Ravnanje nalegajuće površine
  • Nivelacija hilzni (nadvišenje)
  • Ispitivanje bloka

Kako sve to izgleda u praksi?

WORK ORDER CREATION In order to speed up the process of finding adequate spare parts, we advise you to prepare the engine number of your car. It can be found in your vehicle's license card. (Only for Serbian clients). FIRST WASH To give an accurate review as possible, the process of cleaning the engine block is the starting point. The block is washed in special machines that use a special powder to remove grease and crusty oil deposits. REVIEW After the block is thoroughly washed, it is ready for precise measurement. During the review of the cylinder block, the degree of damage to the cylinder is determined, and whether there are visual cracks on the block. Also, the block axis is controlled. The block is now ready for further machining. CYLINDER BLOCK MACHINING Once the degree of damage is established, the block can be bored to a specific measurement, or new cylinder liners may be installed. The first option is to expand the cylinder to a bigger size (oversize), while the resleeving represents the insertion of new liners and boring to the factory size. SURFACE GRINDING (RESURFACING) It is of crucial importance that the cylinder head and cylinder block fit ideally one on top of the other. Sealing these two parts to have factory application is a must, thus the block surface must be ideally flat. CYLINDER HONING The process of cylinder honing represents fine machining after boring or resleeving of the block to obtain an ideal bearing surface of the cylinder. Our latest-generation machines make that process possible with the use of special diamonds for immaculate surface finishing. WASHING & PAINTING At this point, all machining processes are complete. Now is the time to focus on the details to make the cylinder block look like it just came out of the factory. FINAL CONTROL After the completion of all previous processes, our quality control department performs the last measurement checks of all cylinders, as well as a detailed visual inspection of the engine block. PACKAGING FInally, each repaired part of the engine is packed in a protective bag to prevent foreign bodies from entering the treated part. Inside the package you can also find our warranty card / measuring sheet with the exact machining measures.
