CNC (Computer Numerical Control) machines are automated milling machines that are programmed to accurately cut and shape metal, plastic, wood, foam, and other materials. CNC machines are indispensable tools for rapid prototyping, low-volume production, and high-volume mass production. Their efficiency, precision, consistency and ability to run 24/7 with minimal human supervision makes them a staple technology in manufacturing.
When considering purchasing a CNC machine, one of the most important factors is cost. CNC machines range dramatically in price from hobbyist desktop models for a few thousand dollars to industrial 5-axis models that can cost hundreds of thousands of dollars. This article will provide an overview of CNC machine costs to help you determine the right investment level based on your production needs.
Desktop CNC Machines
Desktop CNC machines are small form factor mills designed for hobbyists, educators, and small prototyping shops. They typically have build areas less than 24 x 24 inches and are suitable for working with softer materials like wood, plastics and aluminum. Here are typical price ranges for desktop CNCs:
- CNC 3018 DIY Kits - $200 to $300
These are entry-level machines that come as kits you assemble yourself. They have acrylic or wooden frames and can handle light milling and engraving. Limited rigidity and accuracy.
- Pre-Assembled Desktop Models - $2,000 to $5,000
Pre-built desktop CNCs from companies like Shapeoko, MillRight, Inventables and Tormach are more rigid and accurate than DIY kits. Ideal for serious hobbyists. Can mill wood, plastics and aluminum.
- Small Precision Desktop Models - $5,000 to $15,000
Higher end desktop models like the Tormach PCSNC 440 offer greater precision with ball screws, beefier motors and transmission systems. Can accurately mill steel.
Benchtop CNC Mills
Benchtop CNC mills offer larger work areas and greater rigidity than desktop models. Typical build areas range from 2 x 2 feet up to 4 x 4 feet. Here are typical benchtop CNC price ranges:
- Benchtop Mills Under $10,000
Import benchtop mills from companies like Precision Matthews and Grizzly offer good value but may sacrifice build quality and rigidity. Best for mild steel, aluminum, woods and plastics.
- Mid-Range Benchtop Mills $10,000 to $20,000
Higher precision benchtop mills from Tormach, Shop Sabre and Vision offer greater speeds, accuracy and reliability for machining tougher metals like stainless steel, titanium and hardened tool steel.
- Industrial Benchtop Mills $20,000 to $50,000
Top tier benchtop mills from Haas and Hurco rival the capability of full vertical mills. Feature liquid cooling, high RPM spindles and excellent accuracy and repeatability.
Standalone CNC Mills
Full size CNC milling machines offer the most rigidity, durability and accuracy of all mill types. With build areas from 4 feet square up to 40 feet in length, these industrial mills are built for high-volume production environments. Costs for full CNC mills include:
- Small Vertical Mills Under $75,000
Entry level vertical mills from brands like Sharp, Acra and Lagun are compact and affordable but built for production manufacturing. Excellent for machining larger steel and aluminum parts.
- Mid-Range Vertical Mills $75,000 to $150,000
Widely used mid-level vertical mills from Haas Automation, Mazak and Okuma offer faster spindles, higher precision and smarter software controls. Ideal for machining titanium, tool steels and tough alloys.
- Large Vertical Mills $150,000 to $300,000
Mammoth vertical CNC mills from Doosan, DMG Mori and Makino have enormous work areas with travels between 40-100 inches. Built for high-load, high-precision machining of huge metal parts.
- 5-Axis CNC Mills $200,000 to $1,000,000
The ultimate flexible manufacturing system, 5-axis CNC mills from top brands provide turnkey precision on complex 3D contours. Widely used for aerospace, medical device and mold production.
Clearly, CNC mill prices span a broad range. Carefully assess your business' production needs, budget constraints and growth plans when investing in CNC equipment. Seek advice from manufacturing experts and machine tool suppliers to properly size your machine. With appropriate upfront planning and selection, a CNC mill can deliver many years of reliable service and rapid returns on investment.
Other Cost Considerations
When budgeting for a CNC mill, keep in mind there are other costs beyond the base machine price. Additional key cost factors include:
- Software - CAD/CAM programs for designing parts and generating toolpaths range from around $2,500 up to $15,000 for full suites.
- Fixtures & Workholding - Vises, clamps, jigs and fixtures for securing parts on the CNC table quickly add up. Budget at least $3,000 - $5,000.
- Tooling & Accessories - Initial tooling packages with end mills, drills, taps, reamers, etc. typically cost around $8,000 to $12,000.
- Installation - Rigging, electrical, compressed air and other setup costs can be $5,000 or higher.
- Training - Most buyers budget a few thousand dollars for operator training from the machine supplier.
- Maintenance - Plan on yearly maintenance contracts costing 10-15% of the mill's purchase price.
Buying Used CNC Equipment
One way to acquire CNC milling capability at lower cost is to purchase used equipment through auction sites or classified ads. If properly evaluated, used CNC mills can deliver good value. When vetting pre-owned machines, considerations include:
- Hours of use - Look for low hour machines. More than 40,000 hours raises concerns on wear.
- Condition - Inspect ways, ballscrews, spindle and controls for damage or wear.
- Control electronics - Older controls may not support newer software or G-code.
- Mechanical rigidity - Check for excessive play indicating worn ballscrews.
- Test cuts - Have seller demonstrate accuracy on sample parts.
With careful inspection and reconditioning where needed, used CNC mills can provide years of good service at substantial cost savings over new equipment.
Bottom Line CNC Cost Considerations
Here are key tips when budgeting for a CNC mill:
- Realistically assess your part size, tolerances, volumes and material needs. Match to a CNC mill of appropriate size and capabilities.
- Purchase the most machine your budget allows. More rigid and precise mills hold tighter tolerances and can run faster and longer.
- Consider used equipment to save money, but inspect carefully for wear and damage.
- Factor in all ancillary costs - software, workholding, tooling, installation and training. This can add $20,000 or more.
- Compare options from a variety of machine tool suppliers to find the best combination of price, performance and reliability.
With advance planning and smart selection, investing in a CNC mill will pay off in faster turnaround on orders, reduced labor costs, and consistent high-quality parts production. Carefully weighing CNC machine costs against production needs will help equip your shop for efficiency and competitiveness. CNC Milling CNC Machining
