CNC Machining Equipment cutting tools

  CNC Machining tools Equipment and cutting: have existed since ancient times. They are one of the oldest inventions in human history and have dramatically changed the types of cutting tools we use. Initially, we made them out of stones, so these metal tools are of great value in the world of construction.

 The CNC Tools

Although all CNC Tools serve a purpose, to cut through a material, there is a huge difference in their purpose.

Normally, for a cutting tool to be effective, it must:

 

Be 30% to 50% harder than the material it will work on.

can be fabricated easily.

Has high thermal conductivity.

Has a low coefficient of friction.

Be very resistant to wear.

Be chemically inert and stable.

In practice, various CNC cutting tools perform sawing. Before considering a CNC cutting tool to be used for a specific operation, you need to understand the materials that manufacturers used when producing the tool. Based on that material, we classify cutting tools as:

 

Carbon steel tool

These cutting tools are cheap and are primarily intended for low-speed operations. They have a carbon composition of 0.6 - 1.5% with small amounts of manganese and silicon. They are mainly in twist drills, forming tools, milling cutters, and turning.

High-Speed ​​Steel (HSS)

It is made from high-carbon steel with a fair amount of element alloys such as chromium, tungsten, and molybdenum

It also provides high removal rates for metals and other materials. To improve its property, you have to apply some surface treatments.

 

Earthen pots

These chemically inert tools are corrosion-resistant and 10 times faster than high-speed steel. Typically, aluminum oxide and silicon nitride make up ceramic materials. Projects that require top-notch operation typically use ceramics.

Cemented Carbide

Designed for high-speed operation, these carbide tools are exceptionally tough and can withstand temperatures up to 1000oC. Typically, tantalum, titanium, and tungsten make up them. Works that require a high-quality surface finish also use them.

Other classifications include diamond tools, cubic boron nitride (CBN), sialon, and cermet.

 

CNC cutting tools come in a variety of shapes and sizes and you can use them for a variety of milling and lathe-cutting operations.

 

Some CNC cutting tools are: meet the end

 

Rotational cutting tools that you can use to remove material. Although similar to a drill bit, an end mill is meant for more versatile machining operations. Unlike drill bits that cut material axially, end mills are lateral cutting tools that cut in any direction. Because of their design, some end mills cannot cut the material axially.

 

Generally, there are a variety of tip sizes for end mills and each end mill depends on the desired end product. There are different types of end mills:

The depressions that these tools make are V-shaped. The V-bit can be 90o or 60o, depending on the angle of depression the material requires. Although they often use them to engrave markings on fabric, they are ideal for projects that require excellent sharp edges.

• Straight Flute End Mills: These CNC cutting tools are general-purpose tools that offer high-quality edges.

• Down-cut and up-cut end mills: These spiral tools can create a smooth-surface finish by either moving residue chips down or a rough surface finish by moving residue up and away from a specified area.

The basic anatomy of the end mill consists of a flute (helical groove), cutting edge (teeth), diameter, shank, cut length, and overall tool length.

 

2. Twist Drill: These rotary CNC cutting tools have two flutes and two cutting edges. Through their unique designs, coolants can quickly reach the point of cut action. Manufacturers typically use these cutting tools to reduce production costs and operate with a high degree of finishing.

3. Fly Cutters: These single-point cutters are on a mill and general-purpose fly cutters provide an excellent surface finish.

This CNC cutting tool goes through a clockwise rotation on the surface of a material, making the surface of the material smooth and flat. The fly cutter is for CNCers who want to produce an exquisitely fine finish.

 

4. Cutting fluid and coolant: Cutting fluid flushes material chips away from the cutting area, usually not a CNC cutting tool.

Reducing thermal deformation in the workpiece.

Improvement in tool life.

Surface finish improvement.
