German HERCAT tools HERCAT models HERCAT prices

HERCAT tools utilize electromagnetic technologies such as permanent magnets to assist in mechanical manufacturing processes. They can be categorized into magnetic fixtures, magnetic tools, magnetic molds, and magnetic auxiliary devices. The use of magnetic tools can significantly improve production efficiency and reduce the physical workload of employees. For some workpieces, clamping is inconvenient during machining and assembly due to their structural characteristics. By vertically positioning the U-shaped iron core on the worktable for processing, one only needs to embed a magnet in the locating block of the fixture to firmly hold the workpiece on the worktable equipped with the locating block, ensuring accurate positioning. This greatly simplifies the fixture structure and improves work efficiency. Some products require welding small parts onto the workpiece; if accurate positioning is not achieved, it not only makes the work difficult but also fails to meet requirements.

HERCAT tool types

1) Frame saw. Also known as a rack saw, it consists of an I-shaped wooden frame, twisted rope and twist pieces, and a saw blade. Both ends of the saw blade are fixed to the frame with knobs, which can also be used to adjust the angle of the saw blade. After the twisted rope is tightened, the saw blade is taut and ready for use. Frame saws can be divided into coarse, medium, and fine types based on saw 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 wood. Medium saw blades are 550—650mm long, with a tooth pitch of 3—4mm; medium saws are mainly used for sawing 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 sawing thinner wood and cutting tenon shoulders. 2) Handled saw. The handled saw mainly consists of two parts: the saw edge and the saw handle. It can be divided into single-sided, double-sided, and back-backed handled saws. Single-sided handled saws are 350mm long, with teeth on one side. Depending on the function of the teeth, they can be divided into rip cuts and cross cuts. Double-sided handled saws are 300mm long, with teeth on both sides. Generally, one side is for rip cutting and the other for cross cutting. Back-backed handled saw plates are 250—300mm long. The back of the back-backed handled saw is straightened with a steel strip, and the teeth are finer, available in rip 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, with the blade being approximately 250—750mm long and a tooth pitch of 3—4mm. Panel saws are mainly used for sawing wider wooden boards. 5) Narrow hand saw. The saw blade is narrow and long, with a pointed front end, approximately 300—400mm in length. Narrow hand saws are mainly used for sawing narrow holes and slots. 6) Coping saw. Also known as a fret saw, its construction is similar to that of a frame saw, but the saw blade is narrower (approximately 10mm), mainly used for sawing arcs, curves, and other sections. 7) Wire saw. Also known as a bow saw, it is made by bending a bamboo strip into a bow shape, with steel wire stretched between the two ends. Saw-toothed flying edges are chiseled onto the steel wire, using the sharp edges of these flying edges for sawing. The steel 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.

HERCAT tool structure composition

The function of power components is to convert the mechanical energy of the prime mover into the pressure energy of the liquid. This refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The structural forms of hydraulic pumps generally include gear pumps, vane pumps, and piston pumps. The function of actuating components (such as hydraulic cylinders and hydraulic motors) is to convert the pressure energy of the liquid into mechanical energy, driving the load to perform linear reciprocating motion or rotary motion. Control components (i.e., various hydraulic valves) control and regulate the pressure, flow, and direction of the liquid in the hydraulic system. Depending on the control function, hydraulic valves can be divided into pressure control valves, flow control valves, and directional control valves. Pressure control valves are further divided into relief valves (safety valves), reducing valves, sequence valves, pressure relays, etc.; flow control valves include throttle valves, adjustment valves, flow divider-combiner valves, etc.; directional control valves include check valves, pilot-operated check valves, shuttle valves, directional valves, etc. Depending on the control method, hydraulic valves can be divided into on-off control valves, fixed-value control valves, and proportional control valves. Auxiliary components include oil tanks, oil filters, oil pipes and pipe joints, sealing rings, pressure gauges, oil level and oil temperature gauges, etc. Hydraulic oil is the working medium that transfers energy in the hydraulic system, including various mineral oils, emulsions, and synthetic hydraulic oils.

HERCAT tool features

The electrically controlled powerful chuck has extremely strong holding force, reaching up to 16kg/cm², with uniform and adjustable magnetic force distribution, suitable for various heavy-duty machining, rough machining, and precision machining. Ordinary powerful chucks have weaker and unevenly distributed suction force, unable to withstand the requirements of heavy-duty machining operations. The holding force of the electrically controlled powerful chuck does not require a continuous power supply to maintain, generating no heat during continuous operation, avoiding thermal deformation of the workpiece. Meanwhile, the strong and uniform surface suction force ensures the highest machining precision even if the workpiece extends beyond the table surface. In contrast, ordinary electromagnetic chucks require a continuous supply of current, generating heat after a period of operation, which not only causes thermal deformation of the workpiece but also reduces the magnetic force of the chuck, failing to guarantee machining precision. The electrically 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 will experience a decline in suction force after about half a year of use, while electromagnetic chucks can only operate for a few hours each day, and the equipment is prone to failure, requiring frequent replacement and repair of internal components. Using ordinary powerful chucks requires a significant amount of time for workpiece adjustment, accounting for 40%-50% of the entire machining process, and clamping positioning is prone to obvious errors, resulting in a high scrap rate and very low efficiency. The electrically controlled powerful chuck has an automatic auxiliary positioning function; simply pressing a button completes the clamping or release of the workpiece in 0.3 seconds, greatly improving production efficiency.
