German SIMAT ABRASIVI tools SIMAT ABRASIVI models SIMAT ABRASIVI prices

SIMAT ABRASIVI tools refer to the general term for various metal devices manufactured through physical processing such as forging, rolling, and cutting of metals like iron, steel, and aluminum. Hardware tools, classified by product application, can be divided into: tool hardware, construction hardware, daily-use hardware, locks and abrasives, kitchen and bathroom hardware, home hardware, and hardware components. These include various manual, electric, pneumatic, and cutting tools, automotive maintenance tools, agricultural tools, lifting tools, measuring tools, tool machinery, cutting tools, jigs and fixtures, cutters, molds, cutting edges, grinding wheels, drill bits, polishing machines, tool accessories, measuring tools and cutters, painting tools, abrasives and abrasive materials, manual socket wrench sockets, striking open-end wrenches, and striking box-end wrenches.

SIMAT ABRASIVI tool types

1) Frame saw. Also known as a buck saw, it consists of an H-shaped wooden frame, twisted rope with toggle, and saw blade. The 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 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 sawing thicker lumber. Medium saw blades are 550—650mm long, with a tooth pitch of 3—4mm; medium saws are mainly used for sawing thin lumber or cutting tenons. Fine saw blades are 450—500mm long, with a tooth pitch of 2—3mm; fine saws are mainly used for sawing finer wood and cutting tenon shoulders. 2) Knife saw. A knife saw mainly consists of a saw edge and a handle, and can be divided into single-sided, double-sided, and back-backed knife saws. Single-sided knife saws have a blade length of 350mm, with teeth on one side; depending on the function of the teeth, they can be divided into rip-cut and cross-cut types. Double-sided knife saws have a blade length of 300mm, with teeth on both sides; typically, one side is for rip-cutting and the other for cross-cutting. Back-backed knife saws have a blade plate length of 250—300mm; the back of the blade is reinforced with a steel strip, and the teeth are finer, available in rip-cut 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 sawing wider boards. 5) Keyhole saw. The blade is narrow and long, with a pointed tip, and a length of approximately 300—400mm. Keyhole saws are mainly used for sawing narrow holes and slots. 6) Coping saw. Also known as a fret saw, its structure is similar to that of a frame saw, but the blade is narrower (approximately 10mm), mainly used for sawing arcs and curves. 7) Wire saw. Also known as a bow saw, it is made by bending a bamboo strip into a bow shape and stretching a wire between the two ends. Serrations are cut into the wire to create sharp edges for sawing. The wire is approximately 200—600mm long, and the saw bow is 800—900mm long. Wire saws are mainly used for sawing complex curves and cutting holes.

SIMAT ABRASIVI 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 arranged either longitudinally or transversely. Longitudinal arrangement of rectangular magnetic poles is suitable for securing larger workpieces; transverse arrangement is suitable for securing smaller workpieces. Circular chucks are suitable for securing ring-shaped workpieces or workpieces with complex shapes. The main characteristics of standard electromagnetic chucks are: magnetic flux lines are evenly distributed on the surface of the chuck, magnetic 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 with the same contact area; the point of application of the magnetic force is limited to the contact surface between the workpiece and the chuck and cannot be arbitrarily changed. Therefore, disadvantages during machining include low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency.

SIMAT ABRASIVI tool usage

1) Before use, carefully inspect the tool to ensure there is no external damage, the switch operates flexibly without sticking, and the power cord and housing of the electric tool 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 MΩ. Refer to the attached table for insulation resistance values. 2) Handheld electric 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 electric 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 the related electrical and mechanical protection devices are intact and functioning normally. Also ensure that rotating parts move flexibly without sticking. 5) When using Class I handheld electric 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 electric tools in damp and confined spaces, install a residual current circuit breaker (RCCB) with an operating current of less than 1.5mA and an operating time of less than or equal to 0.1 seconds. The RCCB should be placed inside the container and monitored by dedicated personnel. 6) Occupational hazards associated with the use of handheld electric tools. Arm vibration syndrome caused by long-term exposure to hand-transmitted vibration was listed as one of China's statutory occupational diseases as early as 1957, also known as local vibration disease, typically manifesting as episodic white finger.
