How Does Pricing For CNC Machining Services Work? Breaking Down Fixed And Variable Costs

The pricing structure of CNC machining services itself explains the phenomenon that large and small batches have huge price differences. Many customers will only consider the ultimate unit price without considering the cost allocation logic, which is a big flaw in purchasing decisions.

Unveiling the core pricing model:

The formula is: Total Price = One-time Fixed Cost + (Unit Variable Cost × Quantity). This is a very important formula to understand the price difference and applies to all CNC machining projects.

Cost Analysis for Small Batch Orders: Why Does the Unit Price Appear Higher?

In small batch orders, from 1 to 100 units, the one-time fixed cost is extremely high: programming costs US$200-800, process design US$150-400, etc. When all fixed costs are spread over a small quantity of products, the unit cost shoots up.

What customers are paying for is essentially "knowledge, preparation, and start-up" in return for flexibility, not having to invest in equipment technology.

Economies of Scale in Cost Analysis for Large Batch Orders: How does it reduce the unit price?

In large-volume orders, fixed costs are fully amortized in 1000 pieces or more, and the unit price is mainly dependent on variable costs such as raw materials and machining time. Batch procurement (saving 10% -20%), specialized fixtures (improving efficiency by 30%+)+process optimization, variable cost reduction, significant economies of scale.

Comparison of the cost structure between small batch and large batch production (taking 6061 Aluminum Parts as an example)

Type of Cost	Small Batch (10 pieces)	Large Batch (10,000 pieces)
Programming Fee	$300 (Amortized $30 per piece)	$300 (Amortized $0.03 per piece)
Tool/jig Preparation	$500 (split $50 per item)	$800 (split $0.08 per item)
Raw Materials	$100 ($10 per item)	$90,000 ($9 per item)
Machining Time	$400 ($40 per item)	$30,000 ($3 per item)
Tool Wear	$50 ($5 per item)	$15,000 ($1.5 per item)
First Piece Testing	$200 (split by $20 per item)	$200 (split by $0.02 per item)
Total Cost Per Unit	$155	$13.63

It demonstrated how costs per unit decrease by 91.2% when orders rise from 10 to 10,000 units. Utilizing a full-scale service provider such as JS Precision allows for optimal product lifecycle costs.

Figure 1: Unit Price vs. Quantity graph.As the output increases, the unit price will significantly decrease.

What Are The Main Factors Contributing To The Final Price Of CNC Machining Metal Parts?

Besides order quantity, five core factors jointly determine the cost of CNC machining metal parts:

1. Material Cost: stainless steel and titanium alloys are much more expensive than aluminum and ordinary steel. The price of the raw material of titanium alloy is 5~8 times that of 6061 aluminum.

2. Geometric Complexity: Deep holes, micro-threads, and complex-curved surface increase programming and machining difficulties, deep hole machining efficiency is only 1/3 of ordinary holes.

3. Tolerances and Surface Finish: The tighter the tolerances, the higher the cost. The rise exponentially in a co-relation from ±0.01mm to ±0.05mm. Special Requirements: Additional processes like mirror polishing will need special requirements.

4. Order Quantity: Directly impacts cost amortization per unit. Small batches result in less dilution of cost and higher unit prices, whereas large batches exhibit substantial economies of scale.

5. Requirement on Post-processing: Heat treatment, anodizing, etc., which adds costs in US$5-15/piece and lead time due to the surface area and coating thickness.

Example of Cost Differences for Different Tolerance Requirements (Taking φ20mm Shaft Parts as an Example)

Tolerance Requirements	Machining Equipment	Machining Time for Single Piece	Increase in Per-Piece Cost (USD)	Applicable Scenarios
±0.1mm	Ordinary CNC Lathe	10 minutes	0	Non-Matching Parts
±0.05mm	Precision CNC lathe	15 minutes	8	General matching parts
±0.01mm	High-Precision CNC	30 minutes	25	Core Matching Parts
±0.005mm	Ultra-precision machining equipment	60 minutes	60	Precision instrument parts

Figure 2: Setting strict tolerances will significantly increase the price of parts, as higher precision will lead to increased production time and manual inspection costs.
