German ruko tools ruko models ruko prices

ruko tools: A mechanized tool powered by an electric motor or electromagnet, driving the working head through a transmission mechanism, is called a power tool. It is a hand-held tool that uses a low-power electric motor or electromagnet as the power source 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. According to 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.

ruko tool types

1) Frame saw. Also known as a buck saw, it consists of an I-shaped wooden frame, twisted rope and toggle, saw blade, etc. The two 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 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 sawing thicker lumber. Medium saw blades are 550—650mm long, with a tooth pitch of 3—4mm; medium saws are mainly used for sawing 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 sawing finer wood and cutting tenon shoulders. 2) Knife saw. The knife saw mainly consists of a saw edge and a handle, and can be classified into single-sided, double-sided, and backed knife saws. Single-sided knife saws have a blade length of 350mm, with teeth on one side; depending on the function of the teeth, they are divided into rip saws and crosscut saws. Double-sided knife 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 knife saws have a blade plate length of 250—300mm; the back of the blade is reinforced with a steel strip, the teeth are finer, and they are available as rip or crosscut saws. 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 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) Coping saw. Also known as a fret saw, its construction is similar to that of a frame saw, but the blade is narrower (approximately 10mm), mainly used for sawing arcs, curves, and other shapes. 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 two ends. Saw-tooth-like edges are cut into the wire, using the 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.

ruko tool structure and composition

The function of the power component is to convert the mechanical energy of the prime mover into hydraulic pressure energy. 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 fittings, sealing rings, pressure gauges, oil level and oil temperature gauges, etc. Hydraulic oil is the working medium for transmitting energy in hydraulic systems, and includes several major categories such as mineral oils, emulsions, and synthetic hydraulic oils.

ruko tool features

The electronically controlled powerful magnetic 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 magnetic chucks have weaker and uneven holding force, unable to meet the requirements of heavy machining operations. The holding force of the electronically controlled powerful magnetic chuck does not require a continuous power supply to maintain; it generates no heat during continuous operation, avoiding thermal deformation of the workpiece. Meanwhile, the strong and uniform surface holding force ensures the highest machining precision even if the workpiece overhangs the table. In contrast, ordinary electromagnetic chucks require a continuous current supply, 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 electronically controlled powerful magnetic 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 may experience a decline in holding 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 failure, requiring frequent replacement and repair of internal components. Using ordinary powerful magnetic chucks requires significant workpiece adjustment time, accounting for 40%-50% of the entire machining process, and clamping positioning is prone to obvious errors, resulting in high scrap rates and very low efficiency. The electronically controlled powerful magnetic chuck features automatic auxiliary positioning; simply pressing a button completes workpiece clamping or release in 0.3 seconds, greatly improving production efficiency.
