Why Reliable? JS Precision's Past Project Experience

Reliable experience is important in making selection decisions for machining equipment, and JS Precision's own past experience in CNC turning provides a good basis.

We have been specialized in producing custom CNC turning for the past 15 years, with more than 500,000 CNC turning parts manufactured for over 300 customers in automotive electronics, medical equipment, aerospace, and other industries.In these projects, we optimized the turning manufacturing process and adjusted the processing steps according to different part characteristics, effectively improving production efficiency and yield.

For example, when we were machining titanium alloy implants for a medical customer, we used a CNC turning center to perform turning, grooving, and drilling within one setup, which ruled out cutting problems of material hardening by traditional sequential processes and doubled yield from 85% to 99.5%. On a project on an automotive sensor housing, we reduced lead time by 70% using the multi-processing capability of the turning center.

This is not book data summarization, but our practice in selecting machines while dealing with thousands of complex orders. It will protect you from pitfalls.

JS Precision is a 15-year-old CNC turning facility that has turned over more than 500,000 CNC turning parts and has been providing consistent custom CNC turning manufacturing services. Let us pick the machines appropriately and avoid pitfalls through us.

Unveiling The Fundamentals: Aware Of Their Ancient Characteristics According To The Definition

In order to choose the right equipment, first you need to understand the basic differences between CNC turning objects and CNC turning centers. Their ancient characteristics determine their applications, in turn.

CNC Lathe: To Turn Objects

Definition: CNC lathe is a machine tool that employs a stationary tool in the process of material removal with the assistance of workpiece rotation. It has only the ability to execute axisymmetric geometry such as cones, cylinders, and spheres.

Drawbacks: As CNC lathes need to only machine near the workpiece axis, parts with off-axis holes or flat surfaces to be milled must be turned over to a drill or mill machine for further processing, with added setup time and accuracy susceptibility.In addition, traditional CNC lathes are difficult to adapt to complex turning programs on CNC, and have low programming flexibility in multi process machining.

CNC Turning Center: A Disruptive Multi-Processing Revolution

Definition: A CNC turning center is just a CNC lathe with an added turret-driven and precise C-axis. The workpiece may be placed to be machined and positioned precisely by the C-axis and machine-turned and drilled directly by the turret-driven tool.

Core: It breaks the limits between "turning" and "milling," making it possible to machine complex parts completely on a single machine, without having to be moved to a different machine. This is the most fundamental difference with traditional CNC lathes.

Major Components Of JS Precision Equipment: Unveiling The "Power Source" Of Turning Centers

Major components determine CNC turning centers' complicated machining capabilities. JS Precision turning centers have the optimized major components for the guarantee of machining accuracy and efficiency:

High-rigidity powered turret: An independent "servo electric spindle" is built in every tool station with stable torque and speed. Milling capability is the same as a vertical machining center, and side groove and flat surface machining becomes even more precise.

High-precision C-axis and direct-drive motor: Deliver infinite workpiece rotation and millisecond-level positioning at any angle, the foundation for sophisticated side machining, e.g., angular errors of ≤0.001 degrees when milling circular holes.

Optional Y-axis-A genuine game changer: With vertical tool motion, it allows off-axis machining (e.g., offset holes, asymmetrical contours). This is a key difference between commodity and premium turning centers and is standard on some high-end JS Precision models.

Second spindle (sub-spindle): Enables automated workpiece transfer, allowing a single machine to complete double-sided part machining without manual intervention, achieving complete, "unmanned" manufacturing.

Head-To-Head Comparison: CNC Turning Center Vs. CNC Lathe

Having understood the nature and salient features of each, a comparison of individual dimensions side by side will readily show where they differ and enable you to pick the appropriate one as per your need:

Comparison Dimensions	CNC Lathe	CNC Turning Center
Accuracy and Consistency	Multiple setups can very easily lead to cumulative errors, that is, low positional accuracy between features.	Single setup eliminates cumulative errors, that is, better positional accuracy for all features.
Production Efficiency	Fast machining of simple components, fewer tool changes and cutting cycles.	Very good advantage for complex components, no secondary set-ups and commissioning time, 30%-70% shorter cycle times.
Labor and Space Costs	Requires multiple machines, more space, and multiple operators.	One machine replaces a "lathe + machining center" station, lower space and labor costs.
Operator Skill Requirements	Requires lathe programming and operation skills.	Requires both milling and turning programming combined (e.g., the simultaneous use of G-code and M-code), which is more demanding.

As is apparent from this comparison, both have their own advantages, and the choice should be made based on part complexity and production requirements. To machine uncomplicated axisymmetric bolts, a CNC lathe is suitable. To machine gear shafts with side holes, a CNC turning center is more suitable.

In addition, our online CNC turning services can generate detailed cost estimation reports for different equipment solutions, helping you visually compare and choose.

This comparison illustrates the obvious advantages of employing turning centers for intricate part machining. JS Precision offers online CNC turning services, with a trade-off between efficiency and cost. Do not hesitate to contact and start the collaborative process.

JS Precision's Turning Center Lineup: Determining The Most Suitable Fitting Machining Solution For You

JS Precision offers three types of CNC turning centers to meet different machining needs. You can choose based on part complexity and precision requirement:

1. Cost-Efficient Model: Equipped with live tooling and a C-axis, it can handle most side drilling and slotting applications, e.g., shaft machining with simple side holes. It represents the most cost-effective entry-level solution for advanced machining.The CNC turning price of this model is relatively affordable and suitable for small and medium-sized production.

2. Fully Improved Model: With a second spindle and additional Y-axis included, it gives powerful 3D milling and double-sided machining capabilities. It's best suited for machining high-precision, thin pieces such as medical implants and miniature aerospace parts. It's our bread-and-butter machine.

3. B-Axis Mill-Turning Center: This center is equipped with milling capacity on par with 5-axis machines with a swiveling B-axis head. It's best suited for turning non-rotating components with complex curved surfaces such as specially designed aerospace components. We provide consulting and service for these ultra-high-end processes.

Cost Analysis Beyond Price: Why Are Turning Centers "Cheaper"?

The majority opt against it due to the initial cost of a CNC turning center but the cost per part is less in the long term. Here follows the actual cost breakdown:

Initial Cost: A turning center will be 1.5 to 3 times the cost of a CNC lathe with comparable specifications. For example, a typical CNC lathe would cost around $50,000, while a turning center with comparable specifications would cost between $75,000 and $150,000.

Total Cost Per Part Calculation:

• CNC lathe solution cost = (lathe processing cost + milling/drilling machine processing cost + secondary clamping/transfer time cost + accuracy risk cost). For example, for side hole machining part machining, lathe processing cost is $5 + milling machine processing cost is $3 + clamping and transfer time is $2 + accuracy risk is $1, which comes to a total of $11.
• The total cost of JS Precision turning center solution = (turn-milling combined cost of processing). Cost of processing the same part in the CNC was $8, so $8 per part.

Conclusion: For off-axis features needed parts, common JS Precision's CNC turning center offerings are decreased overall cost per part without secondary clamping, machine occupancy reduction, and process ease. This produces a good ROI by usually recovering the differential purchase price in 2-1 years.

In comparison to JS Precision CNC turning center machine, the investment is higher but the part cost is lower. I can provide you with a precise CNC turning price using your batch quantity of parts. Let me know for sure.

Maximizing Material Performance: Why Can JS Precision Turning Centers Machine A Wider Variety Of Materials?

Materials vary in ease of processing, and thus there is a variation in the ability of CNC turning centers and CNC lathes to process. JS Precision turning centers are superior in machining special materials:

1.Difficult-to-machine materials (such as Inconel and titanium alloy): Machining is completed in one clamping, avoiding chipping and precision drift from repeated work hardening, and enhancing yield by over 30%.

2.Thin-walled parts with material prone to warpage (such as thin-walled aluminum alloy cylinder): Machining is completed in one clamping, avoiding warpage from repeated clampings, which is impossible using traditional sequential machining. Warpage is ≤ 0.002mm.

3.Costly material (e.g., precious metals such as silver and titanium alloy): Minimum near-zero clamping allowance and high accuracy reduce wastage of costly material. As an example, the scrap rate on silver parts was reduced from 5% to less than 1%.

JS Precision CNC turning center machine can perform machining of high-value and hard-to-machine material with assured quality and material usage of CNC turning parts. In case you have special needs for material processing, please get in touch with us for tailored processes.

Decision-Making Process: Selecting The Most Suitable Process For Your Project

If you're still not clear in making the equipment choice, use the following procedure to determine the most effective solution:

1. Determine first if your part is merely axisymmetric and requires just turning. If "yes," the most economical choice is a CNC lathe, for instance, for turning straightforward nuts and bolts.

2. Does your part require off-axis features (e.g., side holes, flats, or face grooves)? Proceed to the next step: Do the off-axis features require high precision? Is the series sufficiently large? If "yes" on both counts, a CNC turning center is an ideal solution, e.g., to turn automotive sensor housings.

3. If your part is a extremely high-volume, axisymmetric part with an extremely simple structure (such as a typical shaft with a production run of over 10,000 units a day), then seek out a Swiss-type machine or a special lathe to increase the efficiency even further.

4. If you frequently switch product types and produce mainly complex, low-volume parts (e.g., more than 10 types per month, 50-100 parts per type), a CNC turning center machine's flexibility will be well worth the investment, eliminating the need for frequent commissioning of multiple machines.

Case Study: How A JS Precision Turning Center Reduced Sensor Housing Delivery Cycle Time By 70%

Most compelling are findings derived from real projects. As an example, let us utilize the sensor housing processing for an automotive electronics client to illustrate the type of transformation that a CNC turning center can bring:

Customer Pain Points

This customer needed to produce an aluminum alloy sensor housing. The original operation was to turn the main body (outside diameter, inside bore, and face) on a CNC lathe, then transfer it to a vertical machining center to mill two side faces and drill a dowel pin hole. The total operation had two setups, two machines, and two programs and took 12 minutes per part to complete.

Moreover, the secondary setup also generated small angular offsets (more than 0.02mm), which resulted in a scrap rate of 8% and consistently delayed delivery dates.

JS Precision Solution

We re-designed the process for the customer, utilizing JS Precision's full Y-axis CNC turning center to complete all machining operations in a single setup. The process step-by-step is as follows:

• Turning all outer circles, inner holes, and end face features of the machined parts, taking 1 minute.
• Rotate C-axis to position the first side face, and then power mill the flat face with a milling cutter, taking 0.8 minutes.
• Rotate C-axis 180 degrees to mill the second symmetrical plane, taking 0.7 minutes.
• Employ the Y-axis offset capability to precisely drill the off-axis locating pin hole, in 1 minute.
• Complete the part and eject it, without any human intervention, in a total of only 3.5 minutes.

Comparison of Results

Comparison Items	Original Process (Lathe + Machining Center)	JS Precision Turning Center Solution
Working Time per Part	12 minutes	3.5 minutes
Yield	92%	99.8%
Number of Equipment Involved	2 units	1 unit
Lead Time	15 days	4.5 days

The figures show that JS Precision's CNC turning center not only saved work time and lead time, but also slashed yield dramatically, which was a vital customer pain point.

FAQs

Q1: If I have a large quantity of straightforward pieces, is a turning center wasting resources?

On high volumes of simplified turned parts (e.g., turning 5,000 typical cylindrical shafts a day), a specific CNC lathe is the more cost-effective route. JS Precision always adheres to the philosophy of "the best fit is the best." We'll give you the best answer, even on less complex CNC lathe work, square and won't mislead you to sell you a turning center.
