Slotting machine for accurate cutting of tools and fine finish

A vertical slotter machine has a vertical movement of ram. It is usually a robust machine with a possibility of tilting the ram by 15 degree from its vertical position to allow the machining of dies easily. This feature is commonly used while cutting clearances in metal stamping dies. It is commonly used for internal machining of blind holes or vertical machining of complicated shapes which are tough to be produced on horizontal shaper. It is very useful for making key ways, machining in square holes, cutting of internal and external teeth on big gears, machining of dies, punches and more. The operation is usually supported on round table which has a rotary feed in addition to the common table movement in cross-directions. The stroke of slotting machine ranges from 300 to 1800 mm. The ram can be crank driven or hydraulically driven. Ram speeds commonly range from 2 to 40m/ min and longitudinal and transverse power feeds range from 0.05 to 2.5 mm/stroke. Cutting action occurs in downward stroke. The pinion which is in mesh with main gear gets its drive from pulley run through the belt by motor. The gear is coupled to the slotted disc. The circular motion of the disc is converted into the reciprocated one by using a connecting rod. The crank pin can be durably set in a slot in the slotted disc at different distances from the center of the slotted disc for different length of arm stroke.

The position of the stroke is adjusted by using the hand lever available for the stroke adjustment. Slotting machine is commonly provided with the horizontal circular work table, however coordinate tables are also offered sometimes. The table is mounted directly over a bed casting and usually heavy work may be placed.

There is a tower nut slotting machine with a feeding mechanism that is arranged on the machine table, a steering mechanism for holding particles, a positioning mechanism which is connected with one side of the steering mechanism for holding articles and a cutting mechanism which is offered with cutting tool, steering mechanism for holding articles consists of a dividing disc and a plurality of frames for holding articles which hold screw caps, the frames for holding articles are discretely arranged on the periphery of the dividing disc.

When screw closure is on the object that does not have screw, simply use nut to be screwed together in the end of screw, make screw closure on object, and when this object be when being in the vibration mode, this nut may be separated from screw due to the project vibration to prevent the nut from getting loose, the producer of screw closure supplies this type of castle nut.

Generally castlenut is used to manually operate cutter that nut is carried out cutting operation on making of the nut of cutting tool. It is slow to cut ditch operation speed and economical but time consuming due to clamping, the cutting operation of tool and rotational positioning of nut.
