Machine tools presentation

Machine tools play a vital role in manufacturing and automation industries. These tools are designed to perform a variety of tasks with precision, accuracy, and repeatability, from drilling, cutting, and shaping to bending, grinding, and polishing. We will explore the different types of machine tools that are used in PowerPoint presentations and provide an overview of their benefits and applications.

Machining operations Presentation

Machining operations is a manufacturing process in wich a cuttin tool is used to remove excess material from workpiece. Machining operations can used to create any regular geometric shape, Most machine tools operate by removing material from the workpiece

Machining operations:

A cutting tool is used to shape, pierce, mill, plane or grind surface.There are two types of cuts:

• Roughing cuts
• Finishing cuts

Cutting

Cutting Presentation

End Milling: The teeth are located on:

• the periphery of the cutter body
• the end face of the cutter

Face milling: The cutting edges are located on the periphery and face of the cutter

Pheripheral milling: The teeth are located on the periphery of the cutter body

Milling is the process of cutting away material by feeding a workpiece past a rotating multiple tooth cutter

Grinder has the task to remove chips from metal parts.The main component are:

• electrically welded steel machine bed
• rigid column table, headstock and a cross saddle
• eletronic handwheels
• brushless motors
• ball screws

The spindle is supported by a hydrodynamic bearing Grinder can be numerycally controlled CNC

Grinding:

Is a turning machine that can perform a variety of tasks. A cutting tool is used to remove material from the rotating workpiece. The first is the woodworking lathe.

Boring machines are machine tools designed to make holes and machine internal work sush as cylindrical cavities and holes in castings and dies. Boring machines may have various configurations. The following are the most common: -Rotatins workpiece + stationary tool: -Stationary workpiece + rotating tool: -Rotating workpiece + counter-rotating tool: Then we have the boring mill that is a boring machine tool used particularly for large workpiece. -Trepanning: -Counterboring: -Pull boring: -Roller burninshing:

Planning refers to a process of material removal and surface finishing... Shapers are metal-cutting machines which the workpiece is held in vise or similar device that is clamped to a table and can be manually operated.

Planning and shaping

A drill is a machine tool, usually motor-driven, fitted with an end cutting tool that is roate in order to create hole or to enlarge an existing hole in a solid material. The most common are: Portable drills Upright drills Radial drill Gang drill

A press is a machine tool used to compress, flatten, or shape a workpiece by pressure. The following are the main types of press brake: Mechanical press brakes -Hydraulic press brakes -Hydraulic-mechanical press brakes -Pneumatic press brakes
