The invention discloses a double-edge adjustable cutting tool for cutting and grooving. The cutting tool comprises a tool bar, wherein the tool bar is provided with an axial adjusting tool holder capable of adjusting along the axial direction of a processed workpiece and a radial adjusting tool holder capable of adjusting along the radial direction of the processed workpiece; the axial adjusting tool holder and the radial adjusting tool holder are respectively provided with a cutting blade for cutting and grooving. The double-edge adjustable cutting tool for cutting and grooving can simultaneously groove or cut at two positions of a workpiece, and can shorten the time of cutting feed, increase the machining efficiency and reduce the production cost.

Double-edge adjustable cutting tool for cutting and grooving

The invention discloses a strong roll pass turning tool and a production process thereof, and belongs to the technical field of cutting turning tools. The strong roll pass turning tool comprises a tool bar, wherein the front end of the tool bar is provided with an upper butt joint groove; the upper end of the tool bar is provided with a pressing fastener through the upper butt joint groove; a positioning groove is arranged under the tool bar; and a tool bit installing groove is milled at the front end of the tool bar above the positioning groove. The strong roll pass turning tool and the production process thereof provided by the invention have the advantages that the displacement trend of the tool bar is eliminated; meanwhile, when the upper surface is inclined, a tool blade is also inclined, so that the cutting edge of the tool blade is a right-angled cutting edge, and the strength of the cutting edge of the tool blade can be improved to the maximum extent; a press plate adopting a reinforced design can resist vibration generated in the turning process, and the rear tail part of the press plate is provided with anti-skid teeth; the press plate can be effectively prevented from moving; meanwhile, the position of the tool blade can be adjusted, or the tool blade is pushed forwards after being shortened through being trimmed and ground, so that the cutting effect is guaranteed;the strength of the tool bar is greatly improved; the usable distance of the tool blade is adjusted; the service life of the tool blade is prolonged; and the use time rate is increased.

Strong roll pass turning tool and production process thereof

The utility model discloses relates to the machining cutter, in particular to an adjustable bit-regrinding strong cut-off lathe tool, comprising a cutter body, a blade, a pressboard, a cutter support board, a countersunk head screw, a countersunkgasket and an inner hexagon screw. A swallow tail slide mechanism is arranged between the cutter body and the cutter support board, and the pressboard is composed of an upper pressing block and an upper pressboard. And a tooth-typed adjusting mechanism is arranged between the upper pressing block and the upper pressboard. So the utility model has the advantages of reasonable structure, firmness, regrinding blade and large adjusting range, and the extending length of the cutter support board can be adjusted according to the diameter size of the work piece.
