One of the most common types of reciprocating machines is the slotting machine. They are primarily being utilized for the making of vertical, horizontal, or flat surfaces. This equipment has similarities with a shaping machine in more ways than one. The only difference is that within this machine, the ram movement is bobbing in the vertical direction. Therefore it is also commonly referred to as the vertical shaper. 

Performance of tasks
This equipment is useful in preparing square-shaped tools and cutting additional materials. All the cutting operations are being conducted in a vertical fashion. This machine is used for the performance of the below-mentioned operations on various work items. Some of the operations carried out are punching holes, cutting a keyway, cutting external and internal gears, making slots, and cutting out the materials in grooves.

Delving into the various types 
The various kinds of machines in this category are highlighted below. They are the puncher slotter and precision slotter. Individuals on the lookout for equipment for punching substantial quantities of metal and wood rely on the puncher slotter. The stroke strength is such that they have the ability to tackle two kilograms within a minute. This equipment is useful for conducting operations that need multiple punching within a short time. After the puncher slotter completes its role, it is the precision slotter that emerges into the picture. They are the ones who provide a finishing touch to the work item. They are used for the incorporation of details. In the procedure, short and lighter cuts are made on the work items.

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.

Working Principle of Lathe Machine Parts-Components

This Lesson will help you to recognize the lathe machines parts and uses of its accessories. Also will explain the different operations of the machine and the factors related to machine operations.

Before using the lathe machine please read all the steps of the operations. Learn the various controls.
Standard Components of Lathe Machine
To operate the lathe machine you have to know about the all part and their function. In the entire lathe machine these part are similar or we can say that these parts are standard. If you learn about functions of the parts. Then you can operate any type of lathe machine.

Bed: Made up of cast iron. Provide a heavy rigid frame. Bed is the ways, which are formed on the bed’s upper surface and run the full length of the bed.

Ways: This is the inner and outer rails that make machine condition parallel to assure accuracy of movement. The ways keep the tailstock and the carriage, which slide on them, in alignment with the headstock.

Head stock: Head stock contains the head stock handle and mechanism that help us to driving the machine, usually in the left side.

Tail stock: Tail stock is to hold the dead centre to support one end of the work being machined. Tail stock is also used to hold the tapered shank drilled reamers and drill chunks.

Gear Box: This is situated inside the head stock. It is proving the no. of speed with geometric ratio, when the levers are moving.

Spindle: Hole through  the head stock through which the bar stock fed, which allow shafts that are up to 2 times the length between  length centers, which is work single time at a time.

Carriage:  Basically carriage is a movable and moves on the outer ways. It is movable support for the cross feed slide and the compound rest. It’s used for mounting and most of the cutting tool, boring and milling operations. You can stop or lock the carriage machine by tightening the carriage clamp screw.

Apron: Attached to the front of the carriage, it has the mechanism and controls for moving the carriage and cross slide.

Cross slide: Mounted on the top of the carriage in a Dovetail. It is move towards the right angle to the axis.

Tool Post: The purpose of tool post is to provide the rigid support for the tools. Tool holder is inserted in slot in the tool post.

Feed rod: Fed Rod is operating by the spindle through the train of gear. It transmits the power to the apron to driven the longitudinal feed and mechanism. Some Lathe don’t have Fed rod.

 Lead Screw: Lead screw is using for the cutting thread. The Lead Screw is operated by the spindle through Train Gear.

Split nut: When closed around the lead screw, the carriage is driven along by direct drive without using a clutch.
Chuck: Lathe chuck is a machine part for holding lathe work. It is mounted on the nose of the spindle. The work is done by jaws which can be moved in radial slots towards the center of the chuck to clamp down .

The four-jaw independent lathe chuck is the most practical chuck for general work The four jaws are adjusted one at a time, making it possible to hold work of various shapes .

The three-jaw universal or scroll chuck can be used only for holding round or hexagonal work.
