In this article we will discuss about:- 1. Introduction to Transfer Lines 2. Objectives of Transfer Lines 3. Methods 4. Control 5. Performance. Introduction to Transfer Lines: The first step in factory automation was to automate the transportation of parts between various machines/ stations. An automated flow line or transfer line consists of several machines/work-stations linked by work handling devices [...]
Machining centres are the most versatile machinery, NC controlled, multifunction, tool changer equipped horizontal or vertical spindle machines. NC Machining centres being faster and more accurate are replacing many-single-purpose machines. Structural elements of machining centres are of cast iron so as to provide excellent vibration dampening and rigidity. Axis slide ways are of rectangular cross-section, hardened and finish ground in [...]
In this article we will discuss about:- 1. Meaning of Automatic Machines 2. Methods of Automatic Machines 3. Classification. Meaning of Automatic Machines: Automatic machines are those machines in which both the work piece handling and the metal cutting operations are performed automatically. These machines have played an important role in increasing the production rate and have been in use [...]
The principle of working of the sliding head type single spindle automatic machine is explained by the sectional view of old type of machine as shown in Fig. 34.2. However some refinements have been carried out in it, but the working principle remains the same. This machine has been developed for manufacturing quantities of small precision components, and is often [...]
