A flat-sided annular blade for a blade ring saw for cutting hard material such as tile along straight paths and curved paths in which the workpiece is moved through the central portion of the blade. In addition to the usual sintered abrasive diamond coating on the outer peripheral portion of the blade, the inner peripheral portion preferably is tapered to a curved inner edge and also is coated with an abrasive, preferably an electroplated diamond coating providing smoother sawing operation and a finishing action on the workpiece.

A sickle drive incorporated into a generally flat package or enclosure or floor. The drive includes an epicyclic mechanism, including a rotatable input element in an upper region of a cavity of the enclosure, and an eccentric element below the input element rotatable eccentrically thereby. A drive arm is connected to the eccentric element for rotation about, and eccentric rotation with, the eccentric element, and extends to a pivot element which can be the only component extending upwardly from the enclosure or floor, such that the shaft will be pivoted by the eccentric movement of the drive arm. A knife arm connects to the pivot element and a sickle knife assembly which will be reciprocated by the pivoting action. A second epicyclic arrangement can be employed such that opposite forces generated by operation of the drive will be largely canceled.

An indexable, helical cutting insert has multiple cutting edges. In tone configuration, the cutting insert includes four helical cutting edges. In another configuration, the cutting insert includes eight helical cutting edges. In any configuration, the cutting insert may include at least one axial clearance slash extending from a bottom surface to one of the side walls forming a wiper on an edge of the axial clearance slash. In any configuration, the cutting insert may include at least one inside cutting edge that extends outwardly a distance from the side wall. The helical cutting insert may also include at least one progressive cutting edge and / or at least one helical cutting edge that is curved inwardly to enable the cutting insert to perform machining operations on cutters having different diameters.

The invention relates to a making device and method for large-section and large-thickness brain tissue slices, and belongs to the related technical field of biological histology and pathology experiments. The device mainly comprises a base with a groove, and the groove is used for preventing interference between a knife and the base when the knife is used for cutting brain tissue; the top of the base is detachably connected with a locating plate and a stop block separately, and the height of the stop block is higher than that of the locating plate; the stop block is a cuboid, and the left side face serves as the datum plane of brain tissue to be cut, wherein the locating plate is provided with guide grooves used for guiding the knife. According to the making device, the locating plate and the stop block are detachably connected, and therefore replacing is convenient; the guide grooves comprise one chopping guide groove and four slicing guide grooves, the distances between the slicing guide grooves and the side wall of the locating plate are different, and therefore the brain tissue slices with different thicknesses can be cut. According to the making device and method for the large-section and large-thickness brain tissue slices, the problem that large-section and large-thickness brain tissue slices of pig brains, cattle brains and the like are difficult to manufacture at high quality is effectively solved.

The invention discloses a metal sheath stripping device for a rail transit cable. The device comprises a base, a fixed base plate, a stand column fixed between the base and the fixed base plate, a left motor support, a right motor support and two motors, wherein one of the two motors is mounted on the left motor support, the other motor is mounted on the right motor support, two sliding blocks are fixed on the lower surface of the left motor support in parallel, two sliding blocks are fixed on the lower surface of the right motor support in parallel, two linear guide rails are arranged on the fixed base plate in parallel and are embedded into grooves of the sliding blocks of the left motor support and grooves of the sliding blocks of the right motor support in sequence, a left baffle provided with an adjusting threaded hole is fixed on the outer side of the left motor support, a right baffle provided with an adjusting threaded hole is fixed on the outer side of the right motor support, a left connecting plate provided with a driving threaded hole is fixed on the outer side of the left baffle, a right connecting plate provided with a driving threaded hole is fixed on the outer side of the right baffle, the left connecting plate and the right connecting plate are located between the two linear guide rails, and the driving threaded holes are located below the left motor support and the right motor support. The metal sheath stripping device for the rail transit cable overcomes the difficulty in cutting and stripping of a metal sheath during detection, connection and installation of metal sheath cables, stripping efficiency is improved, and stripping of long metal sheaths is achieved.

The invention provides a complete set of electric high and low voltage sheet metal shell automatic finishing equipment and processing method, including an actuator, a spacing guide mechanism and a delivery mechanism, the delivery mechanism is installed on the spacing guide mechanism, and the delivery mechanism An executive mechanism is installed on it, and the executive mechanism and delivery mechanism are located directly above the spacing guide mechanism; the present invention can solve the problem that the back of the electrical cabinet sheet metal will be damaged after punching the cooling holes by a stamping machine. There are punched metal burrs. Nowadays, the punched metal burrs are mostly polished by manual hand-held grinding machines. This operation process is cumbersome, and this method is inefficient and cannot meet the needs of modern industrial production.
