German hitec messtechnik tools, hitec messtechnik models, hitec messtechnik prices

hitec messtechnik tools, also known as hand tools, are distinguished from power tools. They primarily rely on manual force to turn or apply pressure. Hand tools are categorized by use into wrenches, pliers, screwdrivers, tape measures, hammers, sockets, cutting tools, scissors, tool sets, and accessories such as tool carts, with each category having different models. Wrenches include open-end wrenches (fixed wrenches), double box-end wrenches, ratchet wrenches (quick wrenches), combination wrenches, pipe wrenches, T type socket wrenches, cross socket wrenches, adjustable wrenches, etc.; pliers include wire cutters, needle-nose pliers, diagonal cutters, snap-ring pliers, slip-joint pliers, water pump pliers, pipe wrenches, locking pliers, etc.; screwdrivers include slotted, Phillips, Pozidriv, hex, and Torx types; sockets are divided into standard sockets, Torx sockets (E type sockets), bit sockets (BIT sockets), spark plug sockets, impact sockets, etc. Common specifications include 1/4", 3/8", and 1/2", where " denotes inches; additionally, each specification is available in 6-point sockets and 12-point sockets; hammers are divided into claw hammers, machinist hammers, ball-peen hammers, rubber mallets, and installation hammers; cutting tools include files, diamond files, tin snips, aviation snips, utility knives, square tube saws, pipe cutters, bolt cutters, etc. Materials include chrome vanadium steel, carbon steel, and alloy steel.

hitec messtechnik tool types

1) Frame saw. Also known as a sash saw, it consists of an H-shaped wooden frame, twisted rope, twist sticks, and a saw blade. The ends of the saw blade are fixed to the frame with knobs, which can 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; 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) Back saw. A back saw mainly consists of a saw blade and a handle, and can be single-sided, double-sided, or backed. 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 rip-cut or cross-cut. 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 cross-cutting. Backed saws have a blade 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 cutting 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 cutting small holes and slots. 6) Coping saw. Also known as a fret saw, it has a similar structure to a frame saw, but the blade is narrower (approximately 10mm), and is mainly used for cutting 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 mounting a wire at both ends. The wire has serrated edges formed by filing, which are used 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.

hitec messtechnik 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 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.

hitec messtechnik tool usage

1) When placing the diamond dressing tool holder into the collet, be careful not to impact the grinding wheel surface. 2) Do not align the single-point diamond dressing tool vertically with the center of the grinding wheel; generally, it should be tilted 10-15°. 3) Do not "quench" (suddenly cool) a heated dressing tool. During dry dressing, maintain sufficient interval time between dressings to allow the heated 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 wheel and perform dressing. 5) If possible, the amount removed from the grinding wheel radius during each dressing should not exceed 0.001 inches. Excessive removal can cause premature wear and frequent breakage of the diamond dressing tool. 6) However, do not remove too little material each time. Grinding wheels used on old or less rigid machines may not require dressing. 7) Note that the dressing tool should not remain in one position for too long. This will polish the wheel surface, generate high temperatures, and damage the diamond dressing tool. Rotate the dressing tool at least once daily. 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 traverse speeds during rough dressing, followed by small removal amounts and slow traverse speeds during finish dressing. This will quickly damage the diamond dressing tool. If possible, it is recommended to use the same traverse speed for both rough and finish dressing.
