CONVENTIONAL MACHINE SHOP

The conventional lathe machine has four jaw chucks mounted on a spindle driven with 3 phase induction motor of 2 HP. It is used to perform various operations like facing, turning, grooving, drilling, threading etc., with changeable tools. The machine is equipped with a gearbox to vary the gear ratio to work with different feed rates.

With this machine, students should be able to:

• Develop the skill to use the conventional machine.
• Learn the usage of automatic feed.
• Learn the machining of a variety of materials at optimum speed and feeds.
• Perform a variety of tasks during their project work.
• Perform different machining operations like facing, turning, drilling, boring, reaming, threading, eccentric turning, knurling, taper turning, etc.

It can be used in the machining of horizontal surfaces with changeable tools. It can also be used in V-groove cutting, groove cutting and spur gear cutting. It is of semi-automatic type of shaping machine with the angular adjustment of a clapper box.

With this machine, students should be able to:

• Develop the ability to machine safely and accurately a given billet according to the dimensions provided in the given drawing and by using many of the set-up and various machining operations associated with the shaper.
• Understand the working of various components during the quick return mechanism.
• Learn the usage of automatic cross-feed system of shaping machines.
• Learn the machining of various materials with different machinability at optimum stroke length and number of strokes per minute.
• Perform a variety of tasks during their project work.

The plain vertical machines are characterized by a vertical spindle parallel to the column face and mounted in a sliding head that can be fed up and down by hand or power.

With this machine, students should be able to:

• Develop a basic understanding of the working principle of vertical milling machines.
• Identify the various milling tools which can be used for different milling operations.
• Analyse various geometries which can be made in this machine.
• Use this machine to make components for various assigned project work.

In a horizontal milling machine, as the name implies, the spindle is situated horizontally. The spindle rotates horizontally. An arbor is attached to the machine, which holds the cylindrical disk shape cutter, which cuts the metal workpiece.

With this machine, students should be able to:

• Identify the various milling tools which can be used for different milling operations.
• Develop a basic understanding of the working principle of a vertical milling machine.
• Analyse various geometries which can be made in this machine.
• Use this machine for gear cutting.

This power hacksaw is a hydraulic control hacksaw machine. It has been designed to cut quickly and accurately all materials from nickel and chrome steel to plastic. An automatic cut-out operates at the completion of the operation and the bow slide returns to the top position. The drive is given to the machine through V-pulleys with provision to adjust the tension of the V-belts fully. The shafts are fitted with taper and ball bearings which eliminate friction.

With this machine, students should be able to:

• Cut out pieces for various purposes, such as sample preparation for the welding shop or fitting shop.
• Cut samples for various projects.

The tool and cutter grinder is used for sharpening and producing milling cutters such as drills, end mills, and step tools. It is also widely used for producing the tools needed in the woodworking and metal-cutting industries.

With this machine, students should be able to:

• Understand the working principle of tool and cutter grinder.
• Make a single-point cutting tool.
• Re-sharpen the tool for reuse.

It is a type of drilling machine which is used to drill holes at the given radial distance when the component size is larger in terms of height with respect to the work table.

With this machine, students should be able to:

• Learn the working of drilling.
• Make a drill hole of the required diameter on a workpiece.

It is a reciprocating machine in which the ram which holds the tool reciprocates in the vertical direction, and the cutting process is done only in the downward stroke and not in the upward stroke. This machine is similar to a shaper or planer machine.

With this machine, students should be able to:

• Cut grooves, keyways and slots of various shapes.
• Make regular and irregular surfaces, both internal and external.
