Key Takeaways

CNC turning gives very exact and accurate results. It is great for parts that need to fit very closely. This process helps cut down on waste and mistakes. It saves money and makes better parts when making many at once. CNC turning can make many different shapes. It works for simple round parts and also for special designs. You can pick from more than 50 materials. These include metals and plastics to fit what your project needs. KEMING can finish orders fast. They do this for both test pieces and big orders. You get your parts when you need them.

CNC turning features

Precision and accuracy

You want your parts to look just like your design. CNC turning helps you get this control. The machines follow computer instructions to move the cutting tool. This makes every part turn out the same. CNC turning can make parts with tight tolerances. It also gives repeatable results, even for big orders.

KEMING uses advanced machines for high precision. You can see this in the numbers below:

Tolerance Type	Precision Level
Standard Production Tolerance	±0.005 inches (0.13mm)
Greater Accuracy Tolerance	±0.002 inches (0.051mm)
Reamed Holes Tolerance	±0.0005 inches (0.0127mm)
Feature Locations Tolerance	±0.002 inches (0.051mm)

CNC turning gives you steady quality. Manual machining can make good parts, but it is hard to keep every piece the same. CNC turning keeps the quality even, so you get fewer defects and less waste. This saves you money because fewer parts are thrown away.

Tip: If you need parts with very tight tolerances, CNC turning is a great choice. You get reliable results each time.

Surface finish and tolerances

You want your parts to look nice and work well. CNC turning makes smooth surfaces and sharp details. The machines move with care, so you get a clean finish with no rough spots. KEMING’s skilled workers can change the process to fit your needs. You can pick a shiny or matte surface.

You also get accurate tolerances. CNC turning lets you pick the exact size for your parts. You can ask for tight tolerances, even as close as ±0.001 inches. This control helps your parts fit together and work right.

CNC turning makes less scrap, so you save money.
The precision lowers the chance of defects during checks.
You get steady quality for big production runs.
Better accuracy means fewer rejected parts.

KEMING’s skill in precision machining helps your parts meet tough standards. You can trust their experience to make parts that match your needs every time.

Types of CNC turning parts

Cylindrical components

Machines and equipment use many round parts. CNC turning is great for making these shapes. The workpiece spins while the cutting tool shapes it. This makes the surface smooth and the size exact.

Here are some common cylindrical parts you might need:

Shafts: These move power or motion in engines.
Bushings: These help parts slide and lower friction.
Bearings: These hold spinning parts and keep them straight.
Pins and Dowels: These connect parts or help line them up.
Connectors and Couplings: These join different pieces together.
Axles: These hold wheels or gears in place.
Spacers and Hubs: These keep parts apart or in position.

KEMING can make these parts with high accuracy. You can order one piece or thousands. Their machines give you the same quality every time.

Tip: If you need round or tube-shaped parts, CNC turning is a smart choice. It works well for small and big orders.

Custom and complex shapes

Sometimes you need more than just round parts. CNC turning can make special shapes too. It works best for parts that are round or have symmetry. You can get cones, disks, or parts with grooves and threads.

The machine spins the material while the tool shapes it. This gives you smooth surfaces and exact sizes. If your part needs tapers or steps, CNC turning can do that.

KEMING’s team helps you make your ideas real. You can get one custom part or many for production. Their process is good for quick samples or big batches.

CNC turning materials

Metals used

You have many choices when you pick metals for your parts. KEMING offers over 50 types of metals, so you can find the best match for your project. Each metal has special qualities that help your part work better.

Here are five metals you might use:

Aluminum gives you lightweight parts. It resists rust and works well in many jobs.
Stainless steel offers strength and lasts a long time. It stands up to heat and keeps its shape.
Brass makes machining easy. It looks nice and resists corrosion.
Titanium gives you strong parts without adding much weight. It works well in tough jobs and is safe for medical use.
Copper helps with electrical and heat flow. It is easy to shape and resists damage from moisture.

You can choose a metal based on what your part needs to do. Some metals work better in high temperatures. Others resist chemicals or wear. KEMING helps you pick the right metal for your design.

Tip: If you need a part that must last a long time or handle stress, stainless steel or titanium may be the best choice.

A few main factors guide your decision. Look at this table to see what matters most:

Factor	Description
Rigidity	Keeps your part stable and strong.
Stability	Stops your part from bending or changing shape.
Processing Performance	Shows how easy it is to machine the metal.
Cost	Helps you balance quality and price.

Plastics and composites

You can also use plastics and composites for CNC turning parts. KEMING gives you many options, so you can match the material to your needs. Plastics work well when you want light weight or special resistance.

Some popular choices include:

Polyvinyl Chloride (PVC) resists sun and water. You see it in medical and building parts.
Acrylic (PMMA) stays clear and does not break easily. It works for signs and displays.
Polyetheretherketone (PEEK) stands up to chemicals and heat. It fits tough jobs.
Polyacetal (POM) keeps its shape and is easy to machine. It works for gears and small parts.
Polyethylene (PE) resists chemicals. You find it in packaging and cars.
Polypropylene (PP) is light and resists chemicals. It works in food and auto parts.
Nylon 66 (Polyamide) is strong and slides easily. It fits gears and bearings.
Garolite G-10 is strong and resists rust. It works well in marine parts.

You should think about how your part will be used. Some plastics resist heat or chemicals. Others stay strong under stress. KEMING helps you choose the right plastic or composite for your project.

Note: If you need a part that must be light and resist chemicals, plastics like PEEK or PP are good options.
