Industrial Metal Cutting and Finishing Tools

Mechanical Cutting Tools

Sierra Alternative and Band Saws

Sierra Alternative: This tool is intended for cutting large pieces or for series production with a minimum contribution of heat.

Band Saw: This features a circular saw supported by two rollers that move in circles by the action of a motor. The rotation speed is adjustable, and it is cooled using taladrina (coolant).

Jigsaws and Manual Cutting Tools

Jigsaw: Used in the repair of bodywork (carrocería), it allows you to work on almost any surface, moving between 200 and 250 beats per minute.

Grounds and Stocks: This manual mechanical cutting tool converts rotary movement into a back-and-forth motion.

Thermal and Abrasive Cutting

Oxy-fuel and Plasma Cutting

Oxy-fuel Cutting (Oxitall): Used for steels, this process consists of subjecting the material exclusively to a temperature sufficient for a high-pressure oxygen jet to perform the cut.

Plasma Cutting: This is a thermal process for melting metal using electricity and gas. It generates temperatures between 15,000 and 20,000°C.

Cutting by Abrasion

Cutting by Abrasion: This method allows the rotation of a disk at high revolutions to cut the material. A disadvantage of this process is the heat generated.

Surface Finishing and Refinement

Filing and Scraping Techniques

Files (Limas): Key characteristics include size, body length (commercial length), and shape. The filing rate is typically between 50 and 60 beats per minute.

Scraping (Raspatge): This process aims to complete or refine surfaces by removing a portion of the material. A scraper consists of:

• Support: The base where abrasive grains are fixed.
• Minerals: Grains of different sizes and high hardness, such as emery (esmerill), flint (silex), or granite.
• Sticker: The compound used to adhere the abrasive grains.

Abrasives and Suspensions

Abrasives in Suspension: These do not have a fixed support; instead, the abrasive is suspended in adhesive-based pastes or water.

Drilling and Assembly Components

Morse Cones and Milling

Morse Cone: These are cones where the diameters fit together. The transmission of motion from the drill machine is made by the adjustment of one to another. They are used in lock bits and conical drill chucks (portabroques), listed from L1 to L6.

Milling: This process is performed in drills so they can house the heads of bolts, ensuring they do not protrude from the piece.
