At HRCCNC, we know your manufacturing needs can change depending on what stage of development your product is in. From validating your initial design to committing to larger production runs, your business needs a manufacturer who can handle both low and high volume CNC machining production.
HRCCNC offers scalable production ability from one-off samples and prototyping to low-volume or high-volume CNC machining based on your project requirements. These high-volume CNC machining services for custom parts include surface finishing as well.
They improve corrosion and wear resistance and enhance durability. Some finishes enhance the texture appearance by mattifying or glossing the surface. To increase hardness or apply decorative colors, certain surface treatments are applied. We offer several types of CNC machining services tailored to your exact application cases and specific technical requirements.
Types of CNC Machining Services We Provide for Custom Parts
HRCCNC can manufacture complex structures for a wide range of industries like aerospace, medical, automotive, robotics, electronics, etc. They require machining with various materials and strict tolerances. This is why we use different types of precision manufacturing technology.
1. CNC Milling
CNC milling is used to manufacture complex structures with tight tolerances. This machining service is operated in our 3-axis, 4-axis, and 5-axis machining centers.
2. CNC Turning
CNC turning system is used to manufacture precision cylindrical and other round parts. This is done in our advanced turning centers to manufacture precision parts like shafts, threaded parts, bushings, etc for different industries.
3. CNC Grinding
To ensure exceptional dimensional accuracy of precision parts, CNC grinding service is applied. For extreme dimensional control and fine surface finish, this precision manufacturing is highly effective.
4. CNC Drilling
We offer CNC drilling of metal and plastic components with precision holes with positional accuracy. It not only helps us create holes, but also patterns and threaded features on substrates of various hardness levels.
5. CNC EDM Machining
CNC EDM machining can be applied when conventional cutting methods fail to provide precision. To achieve accurate cutting precision, this CNC machining utilizes electrical discharge technology.
6. 5-axis CNC Machining
This service is provided to manufacture complex geometrical components with fewer setups. Here, the machine operates simultaneously from different angles. The most common use cases are aerospace, medical, and high-performance devices.
Low-volume Vs High-volume Production
Low-volume Production
Low-volume production serves as a pathway from concept design to large production runs. HRCCNC offers manufacturing sample units starting from one piece. We offer rapid tooling setup that minimizes upfront NRE cost.
Based on functional testing, you can do quick design iterations in a low-volume sample order. Once the small quantity sample components pass your functional testing, you can decide to commit to a larger production run. We ensure a fast turnaround to deliver your custom precision parts sooner, enabling assembly into the final equipment.
Contact us at HRCCNC for one-off samples, prototypes, and low-volume CNC machining.
High-volume Production
HRCCNC provides scalable large production runs tailored for stable output, which also has a predictable timeline. Here are the advantages we offer with our scalable production capacity:
● Cost Efficiency:
CNC machining of automated multi-part fixtures in large volume substantially reduces required time per cycle and cost per unit.
● Repeatable Quality:
Our high-volume CNC machining services offer strict quality control. This ensures consistency in tight tolerances for repeat batch orders.
● Streamlined Supply Chain:
We have direct relationships with raw material suppliers. So, in case of larger production runs, we ensure steady material availability.
Contact HRCCNC with your required large production number along with drawings, required finish, application cases, projected delivery requirements, etc.
Custom CNC Machining Materials We Provide for Prototyping and Component Production
1. Metals Options
- Aluminum 6061 / 7075 / 5052 – Widely used in aerospace structural components, prototypes, automotive housings, brackets, enclosures, heat sinks for its high strength-to-weight ratio.
- Stainless Steel 304 / 316 / 17-4PH – Standard to use for components of various industries requiring exceptional corrosion resistance, such as medical, marine, and food parts.
- Brass C360 – Due to this metal’s high electrical and thermal conductivity with low friction, it is used for components like connectors, fittings, and decorative parts.
- Titanium Grade 5 – Best to use for high-performance aerospace-grade parts and high-strength components for its high heat resistance. Besides, due to its biocompatibility, it is used for medical devices and high-performance components.
- Carbon Steel 1018 / 4140 – Ideally used for components that require high wear resistance, such as machinery, fixtures, shafts, and other tooling components.
2. Plastic Options
- ABS – This plastic is widely used for manufacturing prototype models, handheld device housings, fixtures, enclosures, etc. It provides high impact strength and dimensional stability.
- PC Polycarbonate – Best for optical parts, guards, and transparent parts for its impact resistance and machining ease.
- POM / Delrin – Some common uses are slides, bushings, precision parts, and gears. This plastic is used for its dimensional stability, high mechanical strength, and low friction.
- Nylon PA6 / PA66 – Most commonly used for wear parts, rollers, brackets, and spacers due to its high wear resistance and self-lubricating nature.
- PEEK – It is used for components requiring chemical neutrality and thermal stability. Some common use cases are high-temperature parts, aerospace and medical components.

Custom Metal Surface Finishing Options We Provide
Surface finishing helps CNC machined parts achieve the required appearance, protection, and functional performance. HRCCNC provides tailored surface treatment options to its low- and high-volume production projects for different purposes like visual appearance, corrosion protection, wear resistance, durability, functionality, etc.
1. Appearance Finishes
- As machined
- Sand/Bead blasting
- Polishing
- Brushing
HRCCNC offers these surface finishing options to enhance the appearance and texture of the CNC machining parts. To gain a uniform matte surface finish and low reflectivity, we apply sand blasting to the raw machined parts.
In case of high gloss with a mirror-like reflective finish, we polish the raw components. To gain a satin finish with directional texture, HRCCNC offers brushing as the surface treatment option for the substrate material.
2. Protection Finishes
- Anodizing
- Hard anodizing
- Powder coating
- Black Oxide
- Passivation
These surface finishes are offered to apply over raw components for corrosion protection, wear resistance, and increased durability. Anodizing has a unique application intent other than corrosion resistance. It is also used for decorative color on the raw machined parts.
Hard anodizing results in a thick oxide layer and gives strong wear resistance. For high durability, powder coating surface treatment is applied. Black oxide treatment reduces glare and provides mild corrosion resistance. Passivation on the raw CNC parts is applied to free iron from the substrate and enhances corrosion resistance
3. Functional Finishes
- Electroplating
- Conductive plating
- Wear-resistant coating
- Custom surface finish
Electroplating and conductive plating serve as metal plating for corrosion resistance and their conductive functionality. Wear-resistant coating is applied to CNC machined parts to enhance surface hardness.
HRCCNC can also provide custom surface finishes to your requirements, according to availability. These coatings are mainly applied to raw CNC components for protection, functionality, and durability to extend their service life.
We can recommend suitable surface finishing options based on the part material, application, tolerance, appearance requirements, durability needs, and order quantity.
