high pressure deburring: cleaning of crankcase and cylinderhead - MTM - #1

MTM develops and produces part cleaning systems for the automotive industry. Numerous systems have been installed in fast-paced produc­tion lines for l irge corporations, such as Daimler Chrysler, Volkswagen, BMW, DAF, etc.

Most recently, Dongfeng Cummins has chosen modern MTM technology. Omega model clean­ing machines will be used for highend cleaning of crank casings and cylinder heads in the new motor manufacturin | for diesel trucks.

The MTM cleaning machine guarantees that extreme requi ements for residual dirt are specifi­cally met with complex components such as crank casings and c ylinder heads.

Procedural st ips:

- loading and inloading

- high pressure deburring with targeted lance technology cleaning; robot-guided if required

- high pressure washing; flood injection principle

- rinsing

- pressure pulse blowing

- vacuum dryi !g.

All applications take place in closed chambers, while the part is rotating. The high pressure clean­ing and debur ing is adapted to the component for the following ireas:

- bed plate side

- cylinder head side

- control sid !

- oil canals, leep bore holes

- water mantles

- crank shaft bearings

- camshaft bearings

Several manufacturing steps are required in production. A ter casting, rough work consisting of milling, drilling and turning follows; then there is fine processing with final honing. Frequent positioning and clamping of the components characterize Ihis fully automated manufacturing process, with testing and checking being impor­tant intermediate steps. Reliable intermediate and final removal of lubricating coolant, shavings and burrs from components is critical for achieving a demanding product quality with certainty (dimen­sional accuracy, tolerances, surface quality, etc.) and in the end contributes to the motor's opera­tional safety a nd durability.

The patented world's first is designed as a space-saving round cycle system with an efficient cleaning chamber technology. MTM's Omega was specifically developed for the extremely high cleaning requirements of the automotive industry for integration into fast-paced manufacturing lines with the shortest cycle times.

Up to twelve rocedural steps of aqueous cleaning with the item beeing rotated, swung or at rest can be integrated, including high pressure deburring (150, 400, 800, 1500 bar) and brush cleaning.

The one-time ^:ixing of the work piece allows pre­cise positioni ig - lances can be precisely targeted and inserted i n deep bore holes.
