Process of our brake disc production

Process of our brake disc production Casting The system of forming cold-box consists of a mixture of sand with two resins, this mixture is added to a tool (negative part), where she is forced to pass through a gas called a catalyst to accelerate the solidification of this mixture, resulting Mold the mixture solidified. After making the molds, they are referred to the melting and casting industry.

Fusion

In the induction furnace is added to steel, pig iron (Material noble), scrap iron (used disc brakes, engine housings …), return (chip and channel) and some alloying elements (carbon, silicon .. .) for the ideal composition of the alloy to the established line of brake rotors and drums. When temperature reaches 1200 ° C, it begins the process of fusion of materials, where they then pass into a liquid. When the metal reaches a temperature of approximately 1450 ° C, is taken to analyze a sample in a device called spectrometer, 14 chemical elements and verify that all these are “within” the range of tolerance. Leak It is the process where the liquid metal is removed from the oven and added within the sand molds, and after this process is cooled down (goes to the solid state).

Deburing

After solidification of the parts, there is the separation of these returns to the sand molding process to start the cycle. The parts then go to step Blasting, receiving a discharge of steel shot with high pressure (the goal of this operation is the removal of burrs and surface impurities), then the parts are separated by code and counted.

Definition

Technical Machining Machining is a mechanical process where the whole piece is the result of a process of removing material. It is a relationship between rotation and advancement, thus causing a removal of material. In practice this means submitting a raw material to the action of a machine and / or tool to be worked out .

CNC Machining

In the machining process, parts go through CNC lathes (Computerized Numerical Control) machines, high precision and production. This process is the removal of material and machining, where the piece reaches a speed of 1500 rpm (revolutions per minute) and an insert carbide “cutting” measures specified in the piece. Hurricane In the drilling process is carried out drilling of parts where these holes will be useful to set the piece in the vehicle. Grinding After completion of the holes, the pieces go through a process of finishing the track brake, called grinding, following the same method of work of the CNC. This finish is to ensure that the ski brake disks are parallel to each other. Balancing The balancing process is to leave the piece with its mass distributed as uniformly as possible. The parts are trapped in a machine that spins at 1100rpm, where sensors measure when the play is unbalanced. If the result is found above the tolerance, the play suffers from a small cut, thereby removing some material, either by making the balancing.

Packaging and Shipping

After completion of the entire process of manufacturing the parts, they are taken to the washing process. In this process the parts are hung on hooks that take parts of a product to spray degreaser used to remove possible traces of grease or oil the part. At the end of this line, the pieces are still immersed in a solution of protective oil, in order to protect the piece of oxidation. After this immersion, the parts are removed from the hooks, put into individual plastic bags and placed inside the packaging, which are then carried to the inventory of finished product.
