German felco tools, felco models, felco prices

felco tools utilize electromagnetic technologies such as permanent magnets to assist in mechanical manufacturing processes. They can be categorized into magnetic fixtures, magnetic tools, magnetic molds, and magnetic auxiliary devices. The use of magnetic tools can significantly improve production efficiency and reduce the labor intensity of employees. For some workpieces, clamping is inconvenient during machining and assembly due to their structural characteristics. Simply position the U-shaped iron core vertically on the worktable for processing. By embedding a magnet in the positioning block of the fixture, the workpiece can be firmly adsorbed onto the worktable equipped with the positioning block and accurately positioned. This greatly simplifies the fixture structure and improves work efficiency. Some products require welding small parts onto the workpiece; if accurate positioning is not achieved, it not only makes the work inconvenient but also fails to meet requirements.

1) Squeeze-exhaust suction cups expel all air from the cup by downward squeezing force, creating a negative pressure state inside to hold the workpiece. Advantages include simple structure, light weight, and low cost. However, the suction force is not large, so they are mostly used for workpieces that are not too large in size, thin, and light. 2) Airflow negative pressure suction cups: An airflow control valve injects compressed air from an air pump through a nozzle, forming a high-speed jet that removes air from the suction cup cavity, creating negative pressure to hold the object. If compressed air is available at the job site, using this type of suction cup is convenient and low-cost. 3) Vacuum pump exhaust suction cups: These connect a vacuum pump to the suction cup via an electromagnetic control valve. When the control valve evacuates air, negative pressure forms in the cup cavity to hold the object. Conversely, when the control valve connects the suction cup to the atmosphere, the suction cup loses suction and releases the workpiece. The suction force of vacuum pump suction cups mainly depends on the size of the adsorption area and the degree of vacuum in the inner wall of the suction cup (referring to the thinness of the air in the inner q cavity). This type of suction cup is reliable and has strong suction, but requires a vacuum pump and airflow control system, resulting in higher costs. 4) Mechanical clamping type: The structure of a straight-bar dual-cylinder translational gripper involves gripper fingers installed on a straight bar with finger mounting seats. When pressurized gas enters the rod-side chambers of the single-acting dual cylinders, the two pistons move toward the center to clamp the workpiece; when no pressurized gas enters, springs push the two pistons outward to release the workpiece. A flow divider valve is installed in the cylinder intake line to ensure synchronous movement of the two pistons. This type of end effector is used in loading and unassembly workstations.

felco Tool Classification

Explosion-proof tools are internationally known as "safety tools" and "non-sparking tools," and domestically as "explosion-proof tools." In China, explosion-proof tools produced, sold, and circulated are divided into two main categories by material: 1. Aluminum-copper alloy (commonly known as aluminum bronze) explosion-proof tools, specifically made of high-purity electrolytic copper as the base with added aluminum, nickel, manganese, iron, and other metals to form a copper-based alloy. 2. Beryllium-copper alloy (commonly known as beryllium bronze) explosion-proof tools, specifically made of high-purity electrolytic copper as the base with added beryllium, nickel, and other metals to form a copper-based alloy. Both materials have excellent thermal and electrical conductivity. After heat treatment, the hardness and wear resistance of aluminum bronze are nearly identical to those of beryllium bronze, both reaching above HRC30o. Beryllium bronze is non-magnetic and can be used in strong magnetic field environments. Explosion-proof tools can also be divided into two main categories by manufacturing process: 1. Casting process: A traditional manufacturing process that was the international standard for explosion-proof tool production in the 80s and is still widely used by most domestic manufacturers. Advantages of casting: simple process, low manufacturing cost. Disadvantages: lower product density, hardness, tensile strength, and torque; more pores and sand holes, leading to shorter product service life. 2. Forging process: The latest international manufacturing process, using large presses or punch presses with high heat-resistant forming molds for one-time forging. Advantages of forging: significantly increases product density, hardness, tensile strength, and torque; basically eliminates pores and sand holes, extending the mechanical performance and service life of products by about 1 times compared to traditional casting. Disadvantages: high investment in equipment and molds, resulting in higher costs.

felco Tool Usage

1) When placing the diamond dressing tool head into the holder, be careful not to impact the grinding wheel surface. 2) Do not align the single-point diamond dressing tool head vertically with the center of the grinding wheel; generally, it should be tilted 10-15°. 3) Do not "quench" (suddenly cool) heated dressing tools. During dry dressing, maintain sufficient interval time between dressings to allow the heated dressing tool to cool. 4) Do not assume the grinding wheel surface is ideally flat. At the start of dressing, locate the high points on the grinding wheel and perform dressing. 5) If possible, the amount of material removed from the grinding wheel per dressing should not exceed 0.001 inches on the radius. Excessive removal can cause premature wear and frequent breakage of the diamond dressing tool head. 6) However, do not remove too little material each time. Grinding wheels used on old or less rigid machine tools may not require dressing. 7) Note that the dressing tool should not remain in one position for too long. This will polish the grinding wheel surface, generate high temperatures, and damage the diamond dressing tool. Rotate the dressing tool at least once a day. 8) Do not continue to use worn or damaged dressing tools. Adjust or replace them promptly. 9) Do not select excessive removal amounts and fast lateral feed rates during rough dressing, followed by small removal amounts and slow lateral feed rates during fine dressing. This will quickly damage the diamond dressing tool. If possible, it is recommended to use the same lateral feed rate for both rough and fine dressing.
