German AMF tools AMF models AMF prices

AMF tools are any functional tools connected to the edge (joint) of a robot. This may include robot grippers, robot tool changers, robot collision sensors, robot rotary connectors, robot pressure tools, compliance devices, robot spray guns, robot deburring tools, robot arc welding torches, robot electric welding torches, etc. Robot end-effectors are generally considered peripheral equipment, accessories, robot tools, or arm-end tools (EOA). Mechanical clamping end-effectors used in industrial loading and unloading robots are mostly two-finger claw types. Classified by finger motion, they can be divided into translational and rotational types. Classified by mechanical clamping method, they can be divided into external clamping and internal expansion types. Classified by mechanical structural characteristics, they can be divided into electric (electromagnetic), hydraulic, and pneumatic types, as well as their combinations.

AMF tool types

1) Frame saw. Also known as a rack saw, it consists of an I-shaped wooden frame, twisted rope, twist pieces, and a saw blade. Both ends of the saw blade are fixed to the frame with knobs, which can also be used to adjust the angle of the blade. After tightening the twisted rope, the saw blade is taut and ready for use. Frame saws are classified into coarse, medium, and fine types based on blade length and tooth pitch. Coarse saw blades are 650—750mm long, with a tooth pitch of 4—5mm; coarse saws are mainly used for cutting thicker wood. Medium saw blades are 550—650mm long, with a tooth pitch of 3—4mm; medium saws are mainly used for cutting thin wood or cutting tenons. Fine saw blades are 450—500mm long, with a tooth pitch of 2—3mm; fine saws are mainly used for cutting finer wood and cutting tenon shoulders. 2) Knife saw. A knife saw mainly consists of a saw edge and a saw handle, and can be divided into single-sided, double-sided, and back-backed knife saws. Single-sided knife saws are 350mm long, with teeth on one side; depending on the function of the teeth, they can be divided into rip cuts and cross cuts. Double-sided knife saws are 300mm long, with teeth on both sides; typically, one side is for rip cuts and the other for cross cuts. Back-backed knife saw plates are 250—300mm long; the back of the back-backed knife saw is straightened with a steel strip, and the teeth are finer, available in rip and cross cut versions. 3) Groove saw. A groove saw consists of a handle and a saw blade, with the blade being approximately 200mm long. Groove saws are mainly used for cutting grooves in wood. 4) Panel saw. Also known as a hand saw. It consists of a handle and a saw blade, with the blade being approximately 250—750mm long and a tooth pitch of 3—4mm; panel saws are mainly used for cutting wider boards. 5) Narrow hand saw. The saw blade is narrow and long, with a pointed front end, approximately 300—400mm in length. Narrow hand saws are mainly used for cutting narrow holes and slots. 6) Coping saw. Also known as a bow saw, its construction is similar to that of a frame saw, but the blade is narrower (approximately 10mm), mainly used for cutting arcs, curves, and other shapes. 7) Wire saw. Also known as a bow saw, it is made by bending a bamboo strip into a bow shape, with steel wire stretched between the two ends. Saw-toothed flying edges are chiseled onto the steel wire, using the sharp edges for cutting. The steel wire is approximately 200—600mm long, and the saw bow is 800—900mm long. Wire saws are mainly used for cutting complex curves and opening holes.

AMF tool structure and composition

The cross-sectional shape and distribution of the magnetic core vary depending on the workpiece. Common structures of electromagnetic chucks include rectangular and circular types. Rectangular magnetic poles are further divided into longitudinal and horizontal arrangements. Longitudinal arrangement of rectangular magnetic poles is suitable for fixing larger workpieces; horizontal arrangement is suitable for fixing smaller workpieces. Circular chucks are suitable for fixing ring-shaped workpieces or workpieces with complex shapes. The main characteristics of ordinary electromagnetic chucks are: magnetic flux lines are evenly distributed on the surface of the magnetic disk, electromagnetic attraction cannot be concentrated, and the magnetic force per unit area is relatively small; the direction of the magnetic force is perpendicular to the chuck surface and difficult to change, producing only one type of magnetic force for workpieces of the same contact area; the point of application of the magnetic force on the workpiece is limited to the contact surface between the workpiece and the chuck and cannot be changed arbitrarily. Therefore, disadvantages during machining include low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency.

AMF tool usage

1) Before use, carefully inspect the tool. Ensure there is no external damage, switches operate flexibly without jamming, and power cords and tool housings are intact. Use a 500V megohmmeter to measure the insulation resistance between the winding and the housing; the value must not be less than O.5 megohms. See the attached table for insulation resistance values. 2) Handheld power tools with metal housings must have a reliable protective grounding wire. The power cord should be a multi-core soft rubber-sheathed cable, and the grounding protection wire at both ends must be securely connected. 3) Handheld power tools should be operated by dedicated personnel with appropriate professional knowledge. Strictly adhere to relevant safety operating procedures during use. 4) Before use, check whether related electrical and mechanical protection devices are intact and functioning normally. Also ensure that rotating parts move flexibly without jamming. 5) When using Class I handheld power tools, operators must wear prescribed protective equipment and use qualified protective gear. Take corresponding anti-electric shock safety measures as required, such as installing residual current devices (RCDs) in the power circuit, or having the operator wear insulating gloves, insulating shoes, or stand on an insulating mat. When using Class II handheld power tools in damp and confined spaces, install a residual current switch with an operating current of less than 1.5mA and an operating time of less than or equal to 0.1 seconds. The residual current switch should be placed inside the container and monitored by dedicated personnel. 6) Occupational hazards of using handheld power tools. Arm vibration disease caused by long-term exposure to hand-transmitted vibration was listed as one of China's statutory occupational diseases in 1957, also known as local vibration disease, typically manifested as episodic white finger.
