Deciding which CNC machine to purchase for your shop can be a difficult decision with many factors to consider. The costs of CNC machines range greatly depending on the size, capabilities, accuracy, control systems, and features included. Factors like the number of axes, spindle power, maximum workpiece size, controller type, software, and options can all impact the price.
This buying guide examines the costs associated with purchasing CNC machines to help you select the right CNC machine for your budget and needs.
Key Factors That Determine CNC Machine Costs
- Number of Axes - The number of axes determines the level of complexity for motion control. More axes allow for more complex shaped parts but also increase costs.
- Work Envelope/Table Size - The maximum size of parts the CNC can machine. Larger work areas allow larger parts but cost more.
- Spindle Power - More powerful spindles allow faster material removal rates but add cost.
- Control System/Software - More advanced controls and software add functionality but also cost.
- Precision/Accuracy - More precise machines produce higher accuracy parts but have higher costs.
- Options - Additional options like probing, automation, safety systems, etc. increase costs.
CNC Machine Types and Associated Costs
There are several main types of CNC machines, with different costs:
- Vertical Machining Centers - Range from $50,000 to $500,000+
- Gantry/Bridge Mills - $200,000 to millions
- Knee Mills - $15,000 to $50,000+
- Benchtop/Mini Mills - $3,000 to $20,000
- Standard Engine Lathes - $50,000 to $150,000
- Slant Bed CNC Lathes - $20,000 to $100,000
- Vertical Turning Lathes - $100,000 to $500,000
- Gantry/Bridge Routers - $40,000 to $300,000
- Benchtop Routers - $4,000 to $30,000
Other CNC Machine Types
- EDM (sinker, wire) - $50,000 to $500,000+
- Laser Cutters - $10,000 to $100,000
- Waterjets - $50,000 to $500,000
- Plasma Cutters - $20,000 to $150,000
- Multi-Tasking Machines - $100,000 to $1,000,000
As you can see, CNC machines have a huge range in costs spanning from several thousand dollars to over a million depending on the machine size, type, capabilities, and features. For most small shops, benchtop mills and lathes in the sub $30,000 range are common. Larger manufacturing facilities often utilize CNC machining centers, turning centers, and multi-tasking machines in the $100,000 to $500,000+ range.
Factors That Increase CNC Machine Costs
More advanced and capable CNC machines cost significantly more. Here are some of the biggest factors that increase costs:
- Precision: Machines with higher precision and tighter tolerances have more sophisticated components that cost more. A VMC with 0.0001" accuracy costs far more than one with 0.01" accuracy.
- Size: The work envelope and X-Y-Z travel distances impact cost greatly. A 4'x8' machine costs exponentially more than a 2'x4'.
- Power: Machines with higher horsepower spindles and faster axis speeds allow faster material removal rates but have higher costs.
- Axes: The number of axes (3, 4, 5+) makes motion control more complex and drives up costs substantially.
- Automation: Automated tool changers, pallet changers, robotic part handling all improve productivity but add cost.
- Software: Advanced software and simulation capabilities improve programming but add expense.
- Brand Reputation: Established CNC brands like Haas, Mazak, DMG MORI cost more than generic machines. You pay for the brand name.
- Options: Probing, coolant systems, safety enclosures, chip management, and other options increase costs.
By understanding what capabilities impact costs, you can make informed CNC machine purchasing decisions for your specific machining needs. Focus on the features you absolutely require for your parts and don't overspend on unnecessary capabilities.
Estimating CNC Machine Ownership Costs
The purchase price is only one part of determining the overall costs for owning a CNC machine. You must also account for:
- Maintenance & Repairs: Annual maintenance and repairs average 5% of machine cost.
- Cutting Tools: End mills, drills, inserts - expect to spend 10-20% of machine cost on tools.
- Workholding & Fixtures: Vises, chucks, tombstones to hold parts.
- Software & Training: CAM software, post processors, training.
- Installation: Rigging, electrical, compressed air, foundations.
- Accessories: Coolant systems, air blast, chip removal.
- Shop Modifications: Floor space, power, dust collection.
A good rule of thumb is to estimate your total 1 year CNC ownership costs at 2x the purchase price when factoring in all additional accessories, tooling, training, installation, etc. The machine purchase price is only part of the equation.
Tips for Getting the Best CNC Machine Value
Here are helpful tips to get the most value from your CNC machine purchase:
- Buy only the capabilities you need - avoid over-buying on bells and whistles you won't use. Match the machine to your part size envelope and accuracy needs.
- Consider pre-owned/refurbished - let someone else take the initial depreciation. Pre-owned equipment can offer great value.
- Choose user-friendly control system - you'll waste less time programming and training.
- Take advantage of financing programs - make payments over years rather than paying in full upfront.
- Seek package deals - manufacturers will often discount additional options/accessories when purchased with a new machine.
- Invest in operator training - lack of training leads to wasted time and poor results.
By following these tips and really understanding your machining requirements, you can obtain an appropriately sized CNC machine with the right features for your shop's unique needs, while avoiding overspending. Carefully weigh the productivity gains of additional capabilities versus the costs to maximize your return on investment. With some research and planning, you can find a CNC machine that fits both your machining and budgetary needs. CNC Milling CNC Machining
