German FISCHER tools FISCHER models FISCHER prices

FISCHER tools powered by electric motors or electromagnets, driving the working head through a transmission mechanism, are referred to as power tools. They are hand-held operating tools that use low-power electric motors or electromagnets as power sources to drive the working head via a transmission mechanism. Power tools are divided into handheld and portable types; handheld power tools are more flexible, convenient, and widely used. Many varieties have become essential tools for production and daily life. There are numerous power tool brands. Based on function and application, they are mainly classified into metal cutting power tools, grinding power tools, assembly power tools, and railway power tools. Common power tools include electric drills, electric grinders, electric wrenches and electric screwdrivers, electric hammers and impact drills, concrete vibrators, and electric planers.

FISCHER tool classification

1) Electric planer: One of the main machines used in woodworking and decoration. It is mainly used for planing smooth surfaces of various woods. Products are categorized into short planers and rough planers. Rough planers are mainly used for planing smooth surfaces of straight lumber and can process larger board surfaces; short planers, in addition to planing board surfaces, can be used with various guides to perform rabbeting, edging, and grooving. The main features of using a handheld electric planer are small size, light weight, portability, and ease of use. Compared with manual tools, it significantly reduces labor intensity and improves processing efficiency and quality. When using a handheld electric planer, hold the handle at the rear of the planer body with your right hand and slightly raise the center of gravity of the rear. After starting the power with your left hand, hold the guide handle at the front of the planer, keeping the front center of gravity lower. Follow the sequence where the front of the planer contacts the wood first; once the rear center of gravity steadily contacts the planing surface, push the planer body forward smoothly in the direction of planing with both hands. After completing the planing stroke, lift the front of the planer with your left hand, then pick it up with both hands and return to the starting point for the next pass. Repeat until all planing is completed. 2) Jigsaw: Also known as electric coping saws or electric fine saws. It is a multifunctional cutting tool capable of straight or curved cutting on wooden boards, as well as plastic and metal sheets, especially suitable for cutting complex shapes and geometric figures with small radii of curvature. It is an indispensable multifunctional sawing tool for home renovation and various public interior decoration projects, featuring light weight, compact size, portability, simple operation, and wide application range. Its cutting principle involves a narrow saw blade with upward-facing teeth performing vertical reciprocating motion to cut according to dimensional requirements. When used with a guide plate, it can also perform angled bevel processing. When using an electric jigsaw, fix smaller and thinner wooden boards to the workbench and support the workpiece with your left hand, then gently push the saw forward with your right hand holding the handle. Apply steady and uniform force; do not exert excessive force to avoid injury or damaging the blade. For larger boards, ensure the board is securely fixed, then hold the handle with both hands and push forward for sawing. Follow the marked line during sawing and always keep the blade perpendicular to the board surface to prevent binding or jamming. 3) Circular saw: Also known as a small handheld circular saw. It is a new type of small handheld electric saw equipped with a spring-loaded automatic safety guard and an electronically controlled constant-speed motor. It features simple operation, flexibility, quick adjustment, and high safety and reliability, making it very suitable for home renovation tasks such as cutting various wooden boards and fiberboards. The thickness of wood or boards being cut should generally be 60mm or less. 4) Sanding tools: Also known as small handheld polishers. Mainly used for sanding bare wood before painting various wood finishes, and also for sanding putty coatings. However, sanding putty generates significant dust, severely polluting the environment, so enhanced labor protection is required during operation. Handheld polishers include belt sanders and orbital sanders. Belt sanders are mainly used for rapid sanding of wooden components and products, while orbital sanders are commonly used for sanding larger areas such as wooden floors in home renovations. 5) Small engraving machine: Also known as a groove planner or trimmer. It can be used for grooving, tenoning, drilling, edging, milling, and trimming on various wooden products and components. It can also perform simple edging, milling, grooving, and trimming on lightweight metals such as aluminum alloys and plastic steel, such as aluminum alloy (or plastic steel) doors and windows, balcony frames, and furniture frames. Therefore, it is also one of the commonly used power tools in modern home renovation projects.

FISCHER tool structure and composition

The cross-sectional shape and distribution of the pole 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 fixing larger workpieces; transverse 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 disk surface, magnetic attraction cannot be concentrated, and the magnetic force per unit area is relatively small; the direction of 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 action 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 application range, and low production efficiency.

FISCHER tool features

The electronically controlled powerful chuck has extremely strong holding force, up to 16kg/cm², with uniform and adjustable magnetic distribution, suitable for various heavy machining, rough machining, and precision machining operations; ordinary powerful chucks have weaker and uneven holding force, unable to meet the requirements of heavy machining operations. The holding force of the electronically controlled powerful chuck does not require continuous power supply to maintain, generating no heat during continuous operation, avoiding thermal deformation of the workpiece. Meanwhile, the strong and uniform surface suction ensures the highest machining precision even if the workpiece extends beyond the table surface; whereas ordinary electromagnetic chucks require continuous current supply, generating heat after a period of operation, which not only causes thermal deformation of the workpiece but also reduces the chuck's magnetic force, failing to guarantee machining precision. The electronically controlled powerful chuck can be used continuously; even if operated continuously for more than 20 hours per day, no faults will occur, and no maintenance is required; ordinary permanent magnet chucks experience a decline in suction force after about half a year of use, while electromagnetic chucks can only operate for a few hours per day, and the equipment is prone to failures, requiring frequent replacement and repair of internal components. Using ordinary powerful chucks requires significant workpiece adjustment time, accounting for 40%-50% of the entire machining process, and clamping and positioning are prone to obvious errors, resulting in high scrap rates and very low efficiency; the electronically controlled powerful chuck has an automatic auxiliary positioning function. Simply pressing a button completes workpiece clamping or release in 0.3 seconds, significantly improving production efficiency.
