Classification Of Cnc System And Designation Of Axis

Introduction Of CNC Machines Used In industries:
CNC (Computer Numerical Control) machines are advanced manufacturing tools that have revolutionized
various industries by offering precise, efficient, and automated machining capabilities. Here’s an overview of CNC
machines and their applications in industries:
CNC machines are automated manufacturing devices controlled by computer programs. They use numerical
data input to control the movement of cutting tools and workpieces, allowing for highly accurate and repeatable
operations.

• Different Types Of CNC Machines Used In Industries:
1 CNC Lathe Machine:
• A CNC lathe machine, also known as a turning centre, is used for cylindrical machining operations.
• It rotates a workpiece on its axis while various cutting tools are applied to shape the material.
• CNC lathes are commonly used for tasks such as facing, turning, grooving, threading, and parting.

• They are widely utilized in industries such as automotive, aerospace, and general manufacturing for producing
cylindrical components like shafts, bushings, and fittings with high precision.
2 CNC Milling Machine:

• CNC milling machines use rotary cutters to remove material from a workpiece by advancing it into a rotating
cutter.
• They can perform a wide range of operations, including drilling, slotting, contouring, and 3D surface machining.

• CNC mills are capable of producing complex shapes, pockets, and contours with high accuracy and repeatability.
• They find applications in industries such as meld making, prototyping, aerospace, and automotive manufacturing
for producing components like melds, dies, engine parts, and tooling.

3 CNC Drilling Machine:
• CNC drilling machines are specialized for creating holes in a workpiece with precision and accuracy.
• They use drill bits or other cutting tools to bore holes of various sizes and depths.
• CNC drills can perform drilling operations in a wide range of materials, including metal, wood, plastic, and
composites.
• They are commonly used in industries such as construction, metal fabrication, woodworking, and electronics
manufacturing for applications like hole drilling in structural components, circuit boards, and assemblies.
4 CNC Grinder Machine:
• CNC grinder machines are used for precision grinding operations to achieve tight tolerances and surface
finishes.
• They use abrasive wheels to remove material from a workpiece, producing fine finishes and precise geometries.
• CNC grinders are utilized in industries such as aerospace, automotive, tool and die making, and medical
device manufacturing for grinding operations on components like bearings, gears, shafts, and cutting tools.
5 CNC Plasma Cutting Machine:
• CNC plasma cutting machines use a high-velocity jet of ionized gas (plasma) to cut through electrically
conductive materials.
• They are capable of cutting a wide range of materials, including steel, aluminium, stainless steel, and copper,
with high precision and speed.

• CNC plasma cutters find applications in industries such as metal fabrication, automotive, shipbuilding, and
construction for cutting intricate shapes, parts, and components from sheet metal and plate materials.
