Lathe size and capacity

It is critical to evaluate the size of the parts to be machined. CNC lathes vary in terms of machining capacity, so it is crucial to select one that can handle the maximum diameter and length of the project parts. In addition, the space available in the shop to accommodate the machine and its layout relative to other equipment must be considered.

Control type and software

CNC lathes operate under different control systems, for example, Okuma CNC lathes work with different variants of the OSP control, with the OSP-P500 being the latest version available.  While other brands might use Fanuc or Siemens numerical controls. The choice of system will depend on both the operator’s preference and compatibility with the CAD/CAM software used. A system that is intuitive and easy to program will reduce learning time and improve productivity; for example, a shop with several Okuma machine tools will have the advantage of reduced lead times and greater efficiency.

Number of axis

Traditional CNC lathes typically have two axis (X and Z), but if the job requires more complex geometries, lathes with additional axis (such as Y and C) are an option. These allow milling and other advanced operations to be performed in a single setup, improving efficiency and accuracy. Also, opting for CNC lathes with extra axis and higher precision capabilities can mean greater profitability, as they are flexible for other machining projects.

Spindle speed and power

Spindle speed and spindle power are decisive for the type of material to be machined. Harder materials require more power and a robust spindle, while for small, precise parts, speed is a key factor. A safe approach to determining these variables for your project is to consult with a team of experienced engineers. In our case, our partners and customers are assured of the best advice available in the market, and our engineering team provides advice on equipment, tooling, accessories, peripherals and even automation systems, ensuring an efficient and cost-effective project.

Automation and additional accessories

Modern CNC lathes can include automatic functions such as bar loaders, automatic turrets or in-process gauging systems (in-process gauging) systems. These accessories increase productivity by reducing manual intervention and ensuring greater accuracy in continuous operations. These options can be loading and unloading, but systems can also be added with other CNC machine tools to reduce production times.

Preventive maintenance is crucial to ensure the efficiency of your CNC equipment and that part production goals are met, and is vital to prolonging the life of your CNC lathe or machining center. Considering that everything that can fail will eventually fail, the only way to prevent costly failures and production downtime is intelligently scheduled preventive maintenance.

What are the advantages of preventive maintenance?

• Improve the efficiency of your equipment and keep its components in optimal condition.
• Increase the service life of your CNC machinery
• Prevent costly failures
• Increased safety for your operators
• Higher quality of your final product

Considering all these aspects, scheduled maintenance serves as a preventive strategy to lower the total cost of ownership (TCO) of CNC equipment, because even though it adds up to short-term costs, it reduces potential expenses that could jeopardize the profitability of a piece of equipment or even a project as a whole.

TCO is defined as a tool that helps us evaluate the total costs (the sum of direct and indirect costs) associated with the purchase of CNC equipment or any other capital asset. This resource provides valuable information about the purchase cost, as well as usage and maintenance costs of the machinery.

To properly calculate the TCO of new CNC equipment, it is necessary to add “hidden” costs that are often overlooked, such as the training of your support staff and technicians. Fortunately, this “expense” can be transformed into a preventive investment by approaching experts who not only provide comprehensive solutions, but can also foresee future failures. 

Other expenses to consider are operating costs and electrical and cooling consumption, adjustments to your plant infrastructure, production downtime (planned or unplanned) and possible incidents such as defective parts.

CNC Financing

In addition, let’s remember that the basic principle for the realistic calculation of the cost of ownership of a CNC equipment is based on the sum of those expenses necessary to guarantee its correct operation during the useful life of the machinery. This measure considers both one-time payment values and those expenses recurring with production, such as consumables, tooling, energy and even land use per square meter in relation to its final production.

With all these expenses in mind, having a reliable maintenance service provider with high quality standards becomes a necessity, that is, a key player to have success and profitability in your projects. Do not hesitate to contact our support team, we have at your disposal plans of service hours with no expiration date and great versatility.

In the highly competitive world of cnc manufacturing, efficiency and profitability are key elements for long-term success. Two terms that play a key role in this scenario are Total Cost of Ownership (TCO) and Return on Investment (ROI). Understanding the relationship between these two concepts is essential to making informed and strategic decisions in your cnc manufacturing projects.

Total Cost of Ownership (TCO) is a complete evaluation of all costs associated with the acquisition, implementation and maintenance of a cnc manufacturing project. It is important to consider that the real value of a CNC equipment goes beyond its price, since this means only 15% of the TCO, while the remaining 85% comes from factors as diverse as consumable tools, maintenance, shutdowns and rejected parts, among others.

In other words, TCO goes beyond the initial purchase costs and includes aspects such as the cost of operation, upgrades and, eventually, expenses associated with the end of life of the machinery. It is for these reasons that it is vital to acquire equipment designed to complete and even exceed the average lifetimes of CNC equipment.

Return on Investment (ROI), on the other hand, measures the benefits obtained in relation to the cost of the initial investment. It is a crucial metric for evaluating the profitability of a project in cnc manufacturing. It is calculated by dividing the net benefits by the initial investment costs and is commonly expressed as a percentage. A positive ROI indicates that the investment has been profitable.rsión ha sido rentable.

Strategic interconnection

The relationship between TCO and ROI lies in the ability to optimize costs over the life cycle of a project while maximizing benefits. Here are some key considerations:

Initial investment vs. long-term savings

Making decisions based solely on the initial investment, i.e., the cost of the equipment, can be misleading, as cheaper equipment can be costly in terms of operation and maintenance. A balanced approach considers how the initial investment will impact operating costs over time and thus affect ROI. The solution is simple: consider the initial investment and operating expenses over the lifetime of the equipment, so it will be easier to visualize how higher structural integrity equipment will bring greater benefits and better savings.

Operational efficiency and maintenance

Investing in technologies and equipment that improve the operational efficiency of your project can reduce long-term operating costs. Adopting solutions that minimize downtime, facilitate predictive maintenance and extend equipment life can have a significant impact on TCO and ultimately ROI.

Adaptability to future projects

Flexibility and the ability to adapt to changes in the manufacturing sector are crucial. Investing in technologies and systems that can evolve with market needs and rapid technological innovations can protect the initial investment and improve long-term ROI. Remember, the relationship between TCO and ROI in manufacturing projects is a strategic trade-off. Optimizing costs over time and maximizing profits are essential to ensure your success in the world of cnc manufacturing.

Okuma equipment has a huge advantage, as it has an average record time of 90 months (7.5 years) between failures, which translates into great savings and security in your investment. Use Okuma’s digital tools and calculate the ROI of your operation here: https://www.okuma.com/roi-calculator

In cnc manufacturing, making informed decisions that consider both total costs and potential returns ensures a sound and sustainable investment in the dynamic environment of modern cnc manufacturing. At the end of the day, the path to profitability involves a thorough understanding of how each decision will affect both costs and benefits throughout the life cycle of your project.
