CNC Cutting Tools

The one of the major part of CNC Machine is Cutting tools or Inserts. We need to study the Cutting tools and its nomenclature throughly and also study the materials of Cutting tools and types of tools. The Cutting tools are used to remove unwanted materials in the workpiece and to provide a good finish for a customers need.So the Cutting tools is very important to CNC Machine, if there is no cutting tool in CNC Machine, there is no CNC Machine. So the cutting tools are very important to all CNC Machines

3. Cutting tools and its Characteristics Cutting tool is a device, used to remove unwanted materials from given work piece for carrying out the machining process, cutting tool is fundamental and requirement A cutting tool must have the following characteristics: Hardness Hot Hardness Toughness

4. Requirements of Cutting tools Tools must resist abrasive wear. It must be capable of supporting and retaining smooth, sharp edges. They must be rigid Cutting and clearance angles must be carefully selected.

5. Types of Tool materials High Speed Steel (HSS) High Carbon Steel (HCS) Cast Alloy Cemented Carbide Ceramic Diamond Cobalt

6. Types of Cutting tools Cnc milling tools A machine operation in which a work part is fed past a rotating cylindrical tool with multiple edges (milling machine). HSS with Titanium-nitride coated end mills. Climb milling. Cobalt premium end mills.

7. Milling tools T – 15 cobalt premium steel ball Various types of cutters used in End single End mill CNC Milling machine

8. CNC Turning tools Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, describes a helical tool path by moving more or less linearly while the work piece rotates Types of tools: Indexable insert tools Standard brazed tools

9. Standard Brazed Single point Carbide tools straight Turning Lead Angle Turning Square Nose Pointed Nose Threading Offset Threading End Cutting Offset Side Cutting Offset Round Shank Boring Square Shank Boring

10. Types of tools

11. CNC Drills Drilling is a process of producing a round holes in a solid material or enlarging a existing holes with the use of multi-tooth cutting tools called drills or drill bits. Various cutting tools are available for drilling, but the most common is the twist drill.

12. Types of Drill bits

13. Coolant Feeding Drill bits

14. Inserts Inserts are removable cutting tips, which means they are not brazed or welded to the tool body They are usually indexable This saves time in manufacturing by allowing fresh cutting edges The strength of the inserts also depends upon the shape of the inserts
