Other Lathes and Turning Machines: * Toolroom Lathe and Speed Lathe * Turret Lathe-A turret replaces the tailstock * Chucking Machines-No tailstock * Automatic Bar Machine-Similar to a chuck machine but with a collet Boring on an NC Lathe 7Horizontal Bore Machining
Tailstocks are used with horizontal boring mills and some other tools that hold the workpiece while it is being turned. The tool's shank fits into the tailstock, which then turns the tool as it spins the spindle. Tailstocks can be divided into three general types: fixed, folding, and sliding.
Fixed tailstocks have two positions: one for turning clockwise and another for counterclockwise. They are used when only one direction of rotation is needed for the job at hand. For example, if part of the job requires rotating the workpiece counterclockwise, but not clockwise, then a fixed tailstock would be used. If both directions of rotation were needed, then a folding or sliding tailstock would be required.
Folding tailstocks fold against the body of the lathe when not in use. This saves space when not needed and reduces the overall weight of the machine. Folding tailstocks can be opened by hand or with an automatic opener. These devices pull the stock toward the operator, who then releases it, allowing the tailstock to snap back into place.
The seven distinct types of lathe machines are as follows: Machine for turning engines. Lathe Machine on a Bench Lathe Machine in the Toolroom Machine with a capstan and a turret. Self-feeding Lathe Machine. Semi-Automatic Lathe Machine. Automatic Spindle Lathe Machine.
A machine tool is an industrial device which turns raw materials such as wood, metal, or plastic, into parts or products. The term "machine tool" is often used interchangeably with "lathe", but this is incorrect. A lathe is a type of machine tool, but a machine tool can be any number of things that turn raw material into finished products. For example, a milling machine is a machine tool that uses a rotating cutting bit to remove material from solid objects. The term "machine tool" is also used broadly to describe any mechanical device that performs a repetitive task. For example, a rock drill is a machine tool that uses heat and pressure to create holes in mining equipment.
There are several different types of lathes, each designed to perform specific tasks. In general, though, all lathes work on the same basic principle: rotary motion is converted into linear motion by way of a threaded rod or similar drive mechanism. There are two main types of lathes: hand-operated and motorized.
|Name of Machine||Special Description||Application|
|Crankshaft Lathe||It carries all the attachments, like taper turning and threading, etc. In addition, a number of rests (supports) for the shafts.||It is used for turning very long parts such as turbine and engine shafts and crankshafts.|
Let's take a look at the five different types of lathe tooling: external turning tools, boring bars, parting tools, threading tools, and drills. These aren't the only tools utilized, but they are some of the most fundamental.
External Turning Tools - These tools have a cutting element that is attached to or part of a handle. They are used for finishing turns on small diameter workpieces. The name "external" refers to the fact that these tools are used outside of the lathe bed. They can be hand or power driven. External turning tools can be divided up into two categories: fixed-point and adjustable-point. Fixed-point tools have a single sharpened cutting point that cannot be moved once mounted on the tool holder. This is usually sufficient for finishing small parts, but it can be difficult to mount them securely if tight clearances are required around moving parts. Adjustable-point tools have a spindle that can be tightened down after mounting in a hole in the tool holder body to hold their cutting points firmly in place while still allowing them to be adjusted accurately toward and away from the lathe head. When using either type of external tool, it is important to remember that the more times the tool is used, the more dull it will become. Therefore, it is necessary to sharpen them regularly.
