multi axis cnc machining

If you’re sourcing CNC-machined ABS parts for prototypes, bienes de consumo, or industrial components, understanding the price structure is key to budgeting and avoiding overspending. The price of CNC machined ABS isn’t fixed—it ranges from 20 RMB/piece for simple parts a 1,000 RMB/piece for complex, high-precision components—shaped by material costs, machining complexity, tamaño por lotes, y más. This guide breaks down the core price drivers, proporciona referencias prácticas, shares cost-saving tips, and answers common questions to help you make informed decisions.

1. 6 Core Factors That Affect the Price of CNC Machined ABS

Every component of the price ties to tangible factors—from raw material costs to post-processing needs. Below is a detailed breakdown with real numbers to illustrate their impact:

(1) ABS Material Cost

Material cost forms the baseline of the total price. Standard ABS resin is affordable, but special grades (P.EJ., retraso de las llamas, aficionado a la comida) add to the cost:

ABS Grade TypeGama de precios (RMB/kg)Características claveAplicaciones típicas
ABS estándar10 ~ 20Buena maquinabilidad, basic impact resistancePrototipos generales, non-critical shells
Abdominales con retraso de llama20 ~ 35Cumple con los estándares de seguridad contra incendios (P.EJ., UL94 V-0)Recintos electrónicos (P.EJ., conchas de enrutador)
Food-Grade ABS25 ~ 40No tóxico, compliant with FDA/GB 4806Food contact parts (P.EJ., small appliance interiors)
High-Toughness ABS30 ~ 50Enhanced durability for repeated usePartes funcionales (P.EJ., toy hinges, manijas de herramientas)

Ejemplo: A 100g simple part made with standard ABS costs 1–2 RMB in material (10–20 RMB/kg × 0.1kg). The same part made with food-grade ABS would cost 2.5–4 RMB in material—2.5x more.

(2) Machining Cost (Equipo + Mano de obra)

Machining cost is the largest variable, combining equipment hourly rates and labor fees. It depends on the type of CNC machine and operator skill:

Equipment Hourly Rates

Tipo de máquina CNCHourly Rate (RMB/Hour)Nivel de precisiónMejor para
Ordinary 3-Axis Machining Center60 ~ 150MedioPiezas simples (P.EJ., plato plano, basic holes)
High-Precision 3-Axis Machine150 ~ 300AltoPiezas con tolerancias estrictas (± 0.05 mm)
5-Axis Machining Center500 ~ 1,000Ultra-HighComplex curved parts (P.EJ., conchas personalizadas)

Costos laborales

  • Operator Salary: 50 ~ 100 RMB/hora (varies by region—coastal areas like Guangdong have lower rates due to competition).
  • Programming Fee: 200 ~ 1,000 RMB for complex parts (P.EJ., multi-surface shells) that require custom G-code; simple parts often include programming in the hourly rate.

Ejemplo: A simple ABS part taking 1 hour on an ordinary 3-axis machine (80 RMB/hora) con un 60 RMB/hour operator costs 140 RMB in machining labor—far more than the material cost.

(3) Parte complejidad

Complexity directly increases machining time and skill requirements, pushing prices higher. Below is how complexity impacts per-piece costs:

Nivel de complejidadRasgos claveTiempo de mecanizado (Por pieza)Gama de precios (RMB/Piece)
SimpleSuperficies planas, no curves, 1–2 holes0.5 ~ 1 hora20 ~ 50
MedioMúltiples agujeros, simple curves, paredes delgadas (≥2mm)1 ~ 3 horas50 ~ 200
AltoComplex curved surfaces, paredes delgadas (<2milímetros), porous structures3 ~ 8 horas200 ~ 1,000

Ejemplo: A simple 10cm×10cm ABS plate (10mm de grosor) acepta 0.5 hours to machine and costs 20–50 RMB. A curved ABS shell with 5 holes and thin walls takes 4 hours and costs 200–500 RMB—5–10x more.

(4) Tamaño por lotes

Batch size unlocks volume discounts, as fixed costs (programación, configuración, trial cuts) are spread across more parts. The larger the order, the lower the unit price:

Tamaño por lotesDiscount vs. Single PieceEjemplo: Simple ABS Part (Original Price: 50 RMB/Piece)Unit Price (RMB/Piece)
Single Piece/Small Batch (1–10)0% (No Discount)50 × 10 = 500 RMB (total)50
Medium Batch (11–100)10 ~ 30%50 × 50 × 0.8 = 2,000 RMB (total)40
Lote grande (>100)30 ~ 60%50 × 200 × 0.5 = 5,000 RMB (total)25

Punta de llave: Even small batch increases (P.EJ., de 5 a 20 piezas) can cut unit costs by 10–20%. Por ejemplo, 20 simple parts cost 40 RMB/piece instead of 50 RMB—saving 200 total de RMB.

(5) Requisitos de postprocesamiento

Basic CNC-machined ABS parts have a matte finish, but additional treatments add to the price. Common post-processing steps and their costs:

Paso postprocesadoCosto (RMB/Piece)Objetivo
Pulido10 ~ 30Superficie lisa (reduces roughness from Ra 1.6μm to Ra 0.8μm)
Painting/Oil Spraying20 ~ 50Add color or protective coating
Impresión de pantalla de seda15 ~ 40Add logos or text (P.EJ., control panel labels)
Electro Excripción30 ~ 80Add metallic finish (P.EJ., chrome-like coating)

Ejemplo: A basic ABS part costs 30 RMB. Adding polishing (20 RMB) and silk screen printing (25 RMB) raises the total to 75 RMB—2.5x more.

(6) Regional Differences

Prices vary by region due to labor and competition levels:

  • Áreas costeras (Guangdong, Zhejiang): Lower prices (10–20% cheaper than inland) due to high competition and mature supply chains. Por ejemplo, a medium-complexity part costs 50–180 RMB vs. 60–220 RMB inland.
  • Central/Western Regions: Slightly higher prices, but may offer faster delivery for local clients.

2. Practical Price Reference Table for CNC Machined ABS

To quickly gauge reasonable prices, below is a table of common ABS part types, their prices, and key notes:

Tipo de parteGama de precios (RMB/Piece)Factores claveCasos de uso típicos

3. 4 Proven Tips to Reduce the Price of CNC Machined ABS

You don’t have to compromise on quality to lower costs. Prueba estas estrategias:

(1) Optimize Part Design

  • Simplify geometry: Remove unnecessary curves or thin walls (P.EJ., use straight edges instead of complex arcs) to cut machining time by 20–40%.
  • Reduce part count: Merge multiple small parts into one (P.EJ., a 2-piece bracket becomes 1 pedazo) to eliminate assembly and reduce clamping time.

(2) Choose the Right Batch Size

  • Combine orders: Si lo necesitas 30 parts over 3 meses, order all 30 at once to qualify for a 10–30% discount instead of 10 piezas mensuales.
  • Negotiate “future batch” discounts: Ask suppliers for a lower rate if you commit to reordering (P.EJ., 5% off if you buy 50+ parts within 6 meses).

(3) Select Cost-Effective Post-Processing

  • Skip unnecessary steps: For internal, non-visible parts, skip polishing or painting—save 10–50 RMB/piece.
  • Use batch post-processing: Group parts for painting or silk screening to get volume discounts (P.EJ., 15 RMB/piece instead of 25 RMB for 50+ regiones).

(4) Work with Coastal Suppliers

Suppliers in Guangdong (P.EJ., Dongguan, Shénzhen) or Zhejiang offer lower prices due to competition and efficient supply chains. Por ejemplo, a medium-complexity part costs 50–180 RMB vs. 60–220 RMB from inland suppliers—saving 10–20%.

4. Key Precautions When Quoting CNC Machined ABS

To avoid unexpected costs, keep these in mind:

  • Proofing Costs: Lotes pequeños (1–5 piezas) often have higher unit prices (20–50% more) due to setup and trial cuts. Confirm proofing fees upfront.
  • Requisitos de tolerancia: Tolerancias más estrictas (P.EJ., ±0.05mm vs. ± 0.1 mm) add 10–30% to the price—only specify tight tolerances if necessary.
  • El tiempo de entrega: Órdenes de apuro (P.EJ., 3-day turnaround vs. 7 días) may add a 20–50% premium. Plan ahead to avoid rush fees.

Preguntas frecuentes

  1. Why does a 5-axis machined ABS part cost so much more than a 3-axis part?

5-axis machines offer ultra-high precision (± 0.02 mm) and can machine complex curved surfaces in one setup—eliminating the need for multiple clampings. Sin embargo, they’re more expensive to purchase (10–20x cost of 3-axis machines) y mantener, leading to higher hourly rates (500–1,000 RMB/hour vs. 60–150 RMB/hour for 3-axis). This translates to 2–5x higher part prices.

  1. How much does flame-retardant ABS add to the total price compared to standard ABS?

Flame-retardant ABS costs 20–35 RMB/kg vs. 10–20 RMB/kg for standard ABS—2x more in material cost. For a 100g part, this adds 1–1.5 RMB to the material cost. If the part requires machining, the total price increases by 5–15% (P.EJ., 50 RMB standard part becomes 55–58 RMB).

  1. Can I get a discount if I provide my own ABS material?

Yes—most suppliers offer a 5–15% discount if you supply the ABS resin. Por ejemplo, a 100 RMB part becomes 85–95 RMB. Sin embargo, ensure your material is suitable for CNC machining (P.EJ., no impurities) to avoid machining defects that require rework (which could erase the discount).
