How to calculate the cost of small batch CNC machining?
1. The true cost of CNC processing.
In short, the cost of a small batch CNC machining is any given hourly rate, which averages about £60 / hour. The cost of a small batch CNC machining part is the total cost of raw materials, plus the cost of any special fixtures, plus the man-hours spent processing each part.
It takes years of experience to accurately quote CNC machining parts. There are many factors to consider, each of which has the potential to increase or decrease the cost of machining services.
Following the example of Machining at JTC Machining, give an overview of typical machining processes and how we can help you save money on parts.
Generally speaking, the hourly wage for 3-axis CNC milling in China ranges from RMB200 per hour to RMB600 per hour. In most cases, providers do not disclose their hourly rates to customers.
As the saying goes, you get what you pay for. Slightly higher prices for ISO 9001 certified companies such as JTC Machining reflect the additional quality control checks that each machined part must undergo before being shipped out.
JTC Machining prides itself on its ability to deliver accurate quotes while remaining fair and competitive with its customers. Due to our efficient processing strategy, a recent benchmark test made us cheaper than 92% of our ISO 9001 certified competitors!
2. What are the main factors affecting the price of small batch CNC processing?
The cost of a CNC machining part is really just the sum of the time it takes to make them multiplied by the hourly rate. A greater understanding of all the processes that go into manufacturing will lead to more accurate pricing. These processes include programming, setting up machine tools, deburring, and checking.
Working with a company that really cares about quality and has robust quality assurance processes, such as the JTC Machining, there may be a difference between only 1% of your lots being inspected and 100%. A good example of how you get what you pay for.
There is no doubt that quality is worth the price. If you are willing to place your order with the cheapest supplier you can find, expect the final product you receive to be worth the price.
As a customer, it is beneficial to know what other factors, in addition to the quality control measures already mentioned, affect the price you pay. Listed below, many of these factors are within your control:
- ISO 9001 certification - whether your supplier is truly living up to their quality promises
- Batch size - do you want 1-off or 1,000-off
- Outsourcing - Do you want anodized parts or do you purchase them yourself
- Material choice -- Aluminum is much cheaper to process than steel
- Geometry - Size, shape, and complexity of parts increase the machining cycle
- Lead time - how urgent is your need for the component
- Tolerances - Tighter tolerances add higher risk and require additional inspection time
- Fixture -- Does your component have a complex profile that requires a custom workpiece fixture solution to hold it in place during machining operations
What materials can CNC machining process？
Aluminum alloys are easy to process in large quantities, have a good strength-to-weight ratio and high thermal and electrical conductivity. They are also naturally resistant to corrosion. Aluminum 6061 is a multipurpose aluminum alloy commonly used in CNC machining. It is commonly found in car parts, bicycle parts, sporting goods and other recreational items. This material is highly processable; However, it can be more expensive than other metals and does not withstand well in the presence of salt water or certain chemicals. The 7075 aluminum is an upgrade of the 6061. Ideal for aerospace frames and high performance entertainment equipment, it is the strongest commercial aluminum alloy.
2. Stainless steel
Stainless steel alloys are strong and resistant to deformation, wear and corrosion. 303 stainless steel contains sulfur to improve workability, but this material has many limitations that engineers must keep in mind.
The 303 cannot be cold formed, heat treated or welded. Special attention must be paid to speed/feed and cutter sharpness during CNC manufacturing. That said, the 303 makes excellent nuts, bolts, non-marine grade fittings, shafts and gears.
304 stainless steel is a non-magnetic universal steel used in CNC machining, known for its toughness. It is easy to work and corrosion-resistant like the 303, but weldable. The 304 is ideal for a wide range of consumer and industrial applications, kitchen fittings, water tanks and plumbing, construction, etc. Because of the added molybdenum, 316 stainless steel is more resistant to corrosion than 304 or 303. It is strong, weldable and one of the few Marine grade stainless steels.
Since stainless steel cannot be distinguished by sight alone, engineers should be sure to test raw materials to confirm the properties of the steel they are working with.
3. Carbon steel
Carbon Steel 1045 is a mild steel grade. Manufacturers often use this material for processing because it is cheaper but stronger than most stainless steel. The 1045 is easy to work, weldable, and can be hardened or heat-treated to achieve a variety of hardness.
This material is ideal for making nuts, bolts, gears, shafts, connecting rods and other small, sturdy mechanical parts. The 1045 can also be used in construction applications, but must be finished to prevent rust and corrosion.
Titanium is known for its high strength, toughness and corrosion resistance and is commonly used to make parts for the most demanding aerospace, military and industrial applications. The material is also biocompatible and suitable for medical device manufacturing.
However, titanium is more expensive than any other commercial form of metal, does not polish well, and is a poor electrical conductor. Engineers should also be aware that titanium is difficult to work with and requires special tools.
Nylon is a versatile low-friction thermoplastic commonly used as a metal substitute in CNC manufactured parts. The material is hard, strong, resistant to impact and chemical corrosion, but surprisingly resilient. Nylon responds well to additives and fillers, so engineers can manipulate the material to achieve desired properties.
Popular applications of nylon include electrical molding, fuel system components, gears, food packaging, fabrics, etc. However, nylon tends to absorb moisture, which can negatively affect the dimensional stability of components.
