Crankshaft CNC Machining

Our Crankshaft CNC Machining Equipment

We use top-quality machines to make crankshafts:

• 5-Axis CNC Machining centers that can cut from many angles
• Machines that can drill deep, straight holes
• Special grinding machines that make super-smooth surfaces
• Large turning centers for big crankshafts

With our 5-axis machining technology, we can make complex shapes that simple machines can’t handle. This means better crankshafts with fewer steps.

Materials We Use for Crankshafts

We make crankshafts from many strong metals:

• Forged Steel – Very strong and lasts a long time
• Cast Iron – Good for handling heat in engines
• Inconel – For very hot places like turbo engines
• Special Stainless Steel – Won’t rust in wet places

For racing engines, we often use forged steel because it can handle high stress. Marine engines need materials that fight rust, so we use special stainless steel for those crankshafts.

Our Crankshaft Machining Process

Making a perfect crankshaft takes many steps:

1. Design – We work from your drawings or help design what you need
2. Material Selection – We pick the right metal for your use
3. Rough Machining – First cuts to get the basic shape
4. Heat Treatment – Making the metal stronger
5. Precision Grinding – Making the surfaces very smooth
6. Balancing – Making sure the crankshaft spins without shaking
7. Quality Checks – Careful testing of every part

Our CNC machining service uses computer programs to make cuts exactly where needed. This is much better than old hand methods.

Why Precision Matters in Crankshaft Machining

Crankshafts need to be very exact because:

• They spin thousands of times every minute
• They must be perfectly balanced
• They connect to many other moving parts
• They must last for years without breaking

Even tiny mistakes can cause big problems. That’s why we use precision CNC machining with tolerance as small as ±0.001″ (0.025mm).

Industries We Serve With Our Crankshafts

Our crankshafts are used in many industries:

• Automotive: From small cars to big trucks
• Marine: Boat engines that must work in harsh conditions
• Aerospace: Where reliability is a matter of safety
• Industrial Equipment: Machines that run all day, every day
• Energy Production: Power generators and pumps

We have special knowledge of automotive CNC machining needs. We understand what car and truck makers expect.

Technical Details of Our Crankshaft Machining

Here are some important numbers about our work:

• Machining Tolerance: As small as ±0.001 inches
• Surface Finish: As smooth as Ra 0.4µm (like a mirror)
• Maximum Length: Up to 6 meters for big industrial crankshafts
• Material Hardness: Up to 62 HRC after heat treatment
• Dynamic Balancing: Less than 0.5g imbalance for smooth running

Advanced Processes We Use

Our best crankshafts use these special processes:

• Deep Hole Drilling: For perfect oil channels inside the crankshaft
• Crankshaft Grinding: Making journal surfaces super-smooth
• Dynamic Balancing: Testing and fixing any spin problems
• Heat Treatment: Making the metal stronger in the right places
• Multi-Axis Turning: Cutting complex shapes in one setup

We combine CNC milling and turning to make complete crankshafts without moving them between machines. This makes better parts faster.

Quality Control For Crankshafts

We check every crankshaft carefully:

• Dimensional Inspection: Measuring every part with digital tools
• Material Testing: Making sure the metal meets standards
• Surface Testing: Checking for tiny cracks or problems
• Hardness Testing: Making sure the metal is strong enough
• Balance Testing: Checking that it spins smoothly

Our ISO 9001 certification means we follow strict quality rules for every part we make.
