German nilfisk tools nilfisk models nilfisk prices

nilfisk 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 cycloidal 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.

nilfisk tool types

1) Frame saw. Also known as a sash 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 blade. After the twisted rope is tightened, 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 are 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 backed handled saw is reinforced straight with a steel strip, and the teeth are finer, available in rip-cut and cross-cut versions. 3) Grooving saw. The grooving saw consists of a handle and a saw blade, with the blade being approximately 200mm long. Grooving saws are mainly used for cutting grooves in lumber. 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 in 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 cutting arcs, curves, and similar shapes. 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 two ends; serrated edges are cut into the wire, using the sharp edges of these serrations 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 opening holes.

nilfisk tool structure and composition

The cross-sectional shape and distribution of the pole cores vary depending on the workpiece. Common structural types of electromagnetic chucks include rectangular and circular configurations. Rectangular magnetic poles are arranged either longitudinally or transversely. Longitudinal arrangement of rectangular magnetic poles is suitable for securing larger workpieces, while transverse arrangement is suitable for securing smaller workpieces. Circular chucks are suitable for securing ring-shaped workpieces or workpieces with complex geometries. The main characteristics of standard electromagnetic chucks are: magnetic flux lines are evenly distributed across the chuck surface, magnetic attraction cannot be concentrated, and the magnetic force per unit area is relatively low; the direction of the magnetic force is perpendicular to the chuck surface and difficult to alter, generating 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 freely adjusted. Therefore, machining operations suffer from disadvantages such as low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency.

nilfisk tool maintenance

1) Set: The set is adjusted using a saw set. When setting, engage the slot of the saw set with the saw teeth and apply force to bend them left or right; the degree of set must meet the requirements for the amount of set. 2) Filing: When filing saw teeth, clamp the saw blade in a vise so that the teeth protrude. Depending on the size of the teeth, use a triangular steel file 100～200 mm long, filing each tooth from right to left. Apply uniform pressure with both hands; keep one face of the file vertically tight against the lower edge of the tooth, and the other face against the upper edge of the adjacent tooth. If the set of the teeth is found to be disordered, place the saw blade flat on a steel plate and use a wooden mallet to flatten all the teeth, then reset and refil. In addition, maintain the saw frame; if damage is found to the rope, nuts, knobs, or wooden joints, adjust or repair them promptly.
