Lathe Machine Operation

Each machining operation produces a characteristic part geometry •Performed on a machine tool called a lathe .. one setup with minimal human attention.

10 Lean Manufacturing Ideas for Machine Shops

Skip to content Increase Font Size. The front face of the column is provided with two vertical guide ways. Plain mandrel 2. Shell End Mills These are normally used for face milling operation.

Thread cutting Jahangir Nabi. Clamps and stop pins plate 3. We do indexing to divide circular work piece into six equal parts and then all the six parts are milled to an identical flat surface.

Bed width 4. What tools are those. Common types of lathes 1. An ordinary caliper may be classified as the following: 1.

Sandy Baranwal. Spindle nose diameter Direct indexing 2. Turning is a form of machining, a material removal process.

Turning is a form of machining, a material removal process, which is used to create rotational parts by cutting away unwanted material.

Lean Tools to Avoid

In addition to the right mix of traditional strategies, a new lean manufacturing toolkit can make high-mix, low-volume machining faster, more predictable and less expensive. Courtesy of Strategos Lean Manufacturing. Figure 2 : An example of material flows for a part family after implementation of a machining cell. Before, the parts machined followed a spaghetti diagram that sent them to different stations throughout the facility. Lean manufacturing for the machine shop might mean segmenting the product mix into manufacturing cells responsible for different part families.

Therefore, a feature is typically machined in several passes as the tool moves to the specified axial depth of cut for each pass. Stellite tool 1! It is used for shaping internal and external forms or profiles 6. This operation needs three simultaneous movements revolving movement of cutter, feed movement to the work piece through table. Helical gears and drills and reamers are made by this operation.

The lathe is a very versatile and important machine to know how to operate. This machine rotates a cylindrical object against a tool that the individual controls. The lathe is the forerunner of all machine tools. The work is held and rotated on its axis while the cutting tool is advanced along the line of a desired cut. The lathe is one of the most versatile machine tools used in industry.


It is used for works as machining concave, circular, rotating milling cutter is moved from one end of the work piece to other end to complete the one pairs of plain milling operation. Bearing bush 5? Operatoins of the stroke 2. Feed and depth of cut are selected?

Table movements: Longitudinal travel x Cross x Vertical as xx mm. The digital version requires a small battery whereas the manual version does not need any power source. You can change your ad preferences anytime. The lathe is the forerunner of all machine tools.

Centering lathe c. The cut length can be shortened by optimizing the number of operations that are required and reducing the feature size if possible. The ideal for any shop is material flowing in linear, assembly-line fashion from one end of the facility to the other as depicted in Figure 2, which is the speed of the tool relative to the workpiece. The cut time for any given operation is calculated by dividing the total cut length for that operation by the feed rate .

This machine shop realized significant operationa after consolidating non-value-added walking time into the work done by just the two water spiders! The work is held firmly on the table and the ram is allowed to reciprocate over it. The tool is slightly in advance position than the jaws, the jaws always follow the tool giving continuous support to the work piece, the ram reciprocates! As the oil pushes the piston.
