German dim tools dim models dim prices

dim tools refer to implements used in woodworking. They generally have sharp cutting edges, so safety must be prioritized during use. Frequent sharpening is required, especially for plane blades and chisels, which must be kept sharp to ensure ease of use and quality workmanship, as implied by the saying "sharpening the axe does not delay the woodcutting." Woodworking tools are categorized into power tools, pneumatic tools, and hand tools. Power tools can be divided by function into multi-function tools (such as multi-purpose oscillating tools) and single-function tools (such as electric planers, jigsaws, circular saws, sanders, and engravers); pneumatic tools include polishers and nail guns; hand tools include measuring tools, hand saws, woodworking planes, wood files, hand chisels, and sandpaper.

dim tool types

1) Frame saw. Also known as a buck saw, it consists of an H-shaped wooden frame, twisted rope with a toggle, and a saw blade. The ends of the saw blade are fixed to the frame with knobs, which can also be used to adjust the blade angle. After tightening the twisted rope, the blade is tensioned 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; they are mainly used for sawing thicker lumber. Medium saw blades are 550—650mm long, with a tooth pitch of 3—4mm; they are mainly used for sawing thin lumber or cutting tenons. Fine saw blades are 450—500mm long, with a tooth pitch of 2—3mm; they are mainly used for sawing finer wood and cutting tenon shoulders. 2) Back saw. A back saw mainly consists of a cutting edge and a handle, and can be classified into single-sided, double-sided, and backed saws. Single-sided back 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 saws and crosscut saws. Double-sided back saws have a blade length of 300mm, with teeth on both sides; typically, one side is for rip cutting and the other for crosscutting. Backed 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 as rip or crosscut saws. 3) Groove saw. A groove saw consists of a handle and a saw blade, with the blade being approximately 200mm long. It is 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. The blade is approximately 250—750mm long, with 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) Compass saw. Also known as a bow saw, its construction is similar to that of a frame saw, but the blade is narrower (approximately 10mm), and it is 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 ends. The wire has serrated edges formed by filing, which use their sharp edges for cutting. The wire is approximately 200—600mm long, and the saw bow is 800—900mm long. Wire saws are mainly used for cutting complex curves and openings.

dim tool structure and composition

The cross-sectional shape and distribution of the magnetic poles 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 clamping larger workpieces, while transverse arrangement is suitable for clamping smaller workpieces. Circular chucks are suitable for clamping 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.

dim tool usage

1) Non-sparking tools provide safety assurance for personnel working in flammable, explosive, and corrosive environments, enhancing social safety and allowing workers to operate with greater peace of mind. After daily use, non-sparking tools require proper maintenance, which is critical for their service life. Improper maintenance may prevent the tools from serving effectively over the long term. First, store the tools in a dry place to prevent damage to working components. In daily operations, after 20 consecutive strikes, remove any adhered material from the tool surface, wipe it clean, and then resume use. Do not use continuously, as prolonged friction may cause overheating and potential damage to the tool. 2) After use, wipe off surface dirt and debris, and store in a dry, safe location. 3) For striking tools, do not strike consecutively; allow appropriate intervals after more than ten strikes, and promptly remove any adhered debris before continuing use. 4) Do not exceed the rated torque when using wrenches. Do not extend the lever arm by using sleeves or binding other metal rods, and do not use a hammer to tighten fasteners (except for strike-face wrenches). 5) Cutting-edge tools should be gently touched against a grinding wheel in a water trough for sharpening. Avoid excessive force or prolonged contact with the grinding wheel. 6) During actual operation with striking and chiseling tools, clear site debris and corrosive oxides from the working surface to prevent third-party impacts. Based on the above performance and usage, aluminum-bronze alloy non-sparking tools are more suitable for atmospheric pressure equipment and environments with less stringent explosion-proof requirements (such as gas stations and small oil depots). Beryllium-copper alloy non-sparking tools are suitable for more demanding environments (such as refineries, gas transfer stations, gas production plants, and drilling teams). 7) Remove surface oil stains before using various products, and refer to the instructions for steel tools for usage guidelines.
