German PEDDINGHAUS tools PEDDINGHAUS models PEDDINGHAUS prices

PEDDINGHAUS tools integrate hydraulic systems with conventional tools into a unified assembly. They convert powerful hydraulic power into mechanical motions such as reciprocating linear motion, rotary motion, and trochoidal motion. A complete hydraulic tool system consists of five components: power elements, actuating elements, control elements, auxiliary elements, and hydraulic oil. Hydraulic tools include: hydraulic wrenches, electric pumps dedicated to hydraulic wrenches, hydraulic jacks, hydraulic bolt tensioners, hydraulic flange spreaders, hydraulic nut splitters, hydraulic pullers, etc. Hydraulic tools offer the advantages of high efficiency and convenience. A complete hydraulic tool system consists of five components: power elements, actuating elements, control elements, auxiliary elements, and hydraulic oil.

PEDDINGHAUS tool types

1) Frame saw. Also known as a sash saw, it consists of an I-shaped wooden frame, twisted rope and twist sticks, 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 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 lumber. Medium saw blades are 550—650mm long, with a tooth pitch of 3—4mm; medium saws are mainly used for cutting 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 cutting finer wood and cutting tenon shoulders. 2) Handled saw. The handled saw mainly consists of two parts: the cutting edge and the handle. It can be classified into single-sided, double-sided, and backed handled saws. Single-sided handled 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 handled 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 handled 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. The 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. The blade is approximately 250—750mm long, with 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 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), 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, with wire stretched between the ends. The wire features serrated edges, using the sharp edges for cutting. The wire is approximately 200—600mm long, and the bow frame is 800—900mm long. Wire saws are mainly used for cutting complex curves and openings.

PEDDINGHAUS tool maintenance

1) Proper air supply system: The intake pressure at the tool inlet (not the compressor outlet pressure) is generally 90PSIG (6.2Kg/cm^2). Pressure that is too high or too low will impair tool performance and service life. The intake air must contain sufficient lubricating oil to ensure adequate lubrication of the pneumatic motor inside the tool (place a white paper at the tool exhaust to check for oil stains; the presence of oil stains is normal). The intake air must be free of moisture; using compressed air without an air dryer is inappropriate. 2) Do not arbitrarily disassemble tool parts before operation, as this affects operator safety and may cause tool damage. 3) If the tool has minor faults or fails to achieve its original function after use, do not continue using it; inspect it immediately. 4) Regularly (approximately once a week) inspect and maintain the tool. Add grease (Grease) to rotating parts such as bearings, and add oil (Oil) to the pneumatic motor. 5) When using various tools, strictly adhere to all safety regulations and operating instructions. 6) Select appropriate tools for the job. Tools that are too large can easily cause work-related injuries, while tools that are too small can easily lead to tool damage.

PEDDINGHAUS tool usage

1) When placing the diamond dressing tool holder into the chuck, avoid impacting the grinding wheel surface. 2) Do not align the single-point diamond dressing tool holder vertically with the center of the grinding wheel; it generally needs to 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 dressing 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 grinding wheel and proceed with dressing. 5) If possible, the amount removed from the grinding wheel during each dressing should not exceed 0.001 inches on the radius. Excessive removal can cause premature wear and frequent fracture of the diamond dressing tool holder. 6) However, do not remove too little material each time. Grinding wheels used on old or less rigid machine tools may not require dressing. 7) Note that the dressing tool should not remain in one position for too long. This will polish the grinding 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 lateral feed rates during rough dressing, followed by small removal amounts and slow lateral feed rates during finish dressing. This will quickly damage the diamond dressing tool. If possible, it is recommended to use the same lateral feed rate for both rough and finish dressing.
