Text b Grinding machine
I. Read the text about grinding machines and find answers to the following questions.
1. What is a grinding machine?
2. What are the main parts of a grinding machine?
3. How is material removed from the workpiece in the grinding machine?
4. What is the coolant used for?
Grinding machine is a machine tool used for grinding, which is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel’s surface cuts a small chip from the workpiece via shear deformation.
The grinding machine consists of a power driven grinding wheel spinning at the required speed which is determined by the wheel’s diameter and a bed with a fixture to guide and hold the work-piece. The grinding head can be controlled to travel across a fixed workpiece or the workpiece can be moved whilst the grind head stays in a fixed position. Very fine control of the grinding head or tables position is possible or using the features of NC or CNC controls.
Grinding machines remove material from the workpiece by abrasion, which can generate substantial amounts of heat; they therefore incorporate a coolant to cool the workpiece so that it does not overheat and go outside its tolerance. The coolant also benefits the machinist as the heat generated may cause burns in some cases. In very high-precision grinding machines (most cylindrical and surface grinders) the final grinding stages are usually set up so that they remove about 2/10000mm (less than 1/100000 in) per pass, this generates so little heat that even with no coolant, the temperature rise is small.
Text c Milling Machine
I. Read the text about milling machine and find answers to the following questions.
1. What is a milling machine?
2. How does the rotating cutter move in the milling machine?
3. What operations can milling machines perform?
4. How can milling machines be operated?
A milling machine is a machine tool used for the shaping of metal and other solid materials. Its basic form is that of a rotating cutter which rotates about the spindle axis (similar to a drill), and a table to which the workpiece is attached. In contrast to drilling, where the drill is moved exclusively along its axis, the milling operation involves movement of the rotating cutter sideways as well as 'in and out'. The cutter and workpiece move relative to each other, generating a toolpath along which material is removed. The movement is precisely controlled, usually with slides and leadscrews or analogous technology. Often the movement is achieved by moving the table while the cutter rotates in one place, but regardless of how the parts of the machine slide, the result that matters is the relative motion between cutter and workpiece. Milling machines may be manually operated, mechanically automated, or digitally automated via CNC (computer numerical control).
Milling machines can perform a vast number of operations, some of them with quite complex toolpaths, such as slot cutting, planing, drilling, diesinking, rebating, routing, etc. Cutting fluid is often pumped to the cutting site to cool and lubricate the cut.
