Why Use Combined CNC Milling and Turning Services?

This is a question that many manufacturers and OEM/ODM partners in sectors like home appliances, agricultural machinery, and automotive industries are increasingly asking, especially as demand for high-precision, custom metal components grows. For traditional single-process CNC operations, producing parts that require both rotational shaping (turning) and multi-sided cutting (milling) often involves transferring workpieces between different machines, which not only increases the risk of alignment errors but also extends production timelines. In contrast, combined CNC milling and turning services integrate these two core processes into a single workflow, allowing for the creation of intricate components—such as the precision hinges and CNC parts that HRB Industries Group specializes in—without the need for multiple handling steps. HRB, a seasoned B2B manufacturer with over 25 years of industry experience, leverages this integrated approach to craft components that meet the strict tolerances of global brands like Electrolux and John Deere, ensuring that even complex parts maintain consistent quality across batches.

A key answer lies in the significant cost savings that come from process consolidation. Standalone CNC milling and turning services typically incur separate setup fees, machine operation costs, and logistics expenses for transferring parts between facilities or workstations. For bulk custom orders—like the 38 million+ defect-free products HRB delivered to a leading global appliance brand with 0 PPM (parts per million) defect rate—these incremental costs can add up dramatically. By adopting combined CNC milling and turning services, manufacturers eliminate redundant steps: HRB, for example, integrates this dual-process capability with its existing sheet metal fabrication, casting, and finishing workflows, achieving a 41% unit cost reduction in oven hinge production through automation of its integrated CNC lines. This multi-process integration not only cuts direct production costs but also reduces material waste, as the unified workflow minimizes workpiece rejections (HRB’s automated lines achieve 90% fewer rejections for ISO-certified hinges) and optimizes material utilization for custom-sized components.

Precision is another compelling reason, particularly for industrial components that demand tight dimensional accuracy. In single-process operations, repositioning workpieces between milling and turning machines can introduce micrometer-level deviations, which are unacceptable for safety-critical parts like agricultural machinery components or automotive hardware. Combined CNC systems, however, use a single fixture to hold the workpiece throughout both processes, ensuring that all cuts and shaping operations align with the original design specifications. HRB’s Black Belt quality team and state-of-the-art inspection systems complement its combined CNC milling and turning services, maintaining ISO 9001:2008 certified standards across every product. The company’s investment in AI vision technology for its CNC lines further elevates quality control, enabling real-time detection of potential defects and ensuring that components—from custom CNC parts to appliance hinges—meet the reliability requirements of its global OEM partners.

For businesses seeking customized metal fabrication solutions, this integrated service aligns perfectly with the demand for flexible, end-to-end manufacturing support. HRB Industries Group, which specializes in empowering client ideas through customized manufacturing with multi-process integration, uses combined CNC milling and turning services to address the unique needs of its diverse client base. For home appliance clients, the service enables the production of hinges with both turned cylindrical joints and milled mounting brackets in one cycle; for agricultural machinery partners like John Deere, it supports the creation of robust CNC-machined and turned components that withstand harsh field conditions. Additionally, HRB’s U.S. warehouse in St. Louis, MO, ensures that components produced via its combined CNC services can be delivered quickly to North American clients, reducing supply chain lead times and maximizing customer productivity.

In today’s competitive industrial landscape, speed to market can make or break a product’s success, and integrated CNC processes are a game-changer in this regard. Standalone milling and turning operations often require separate design validations and production schedules, delaying product launches. Combined services, by contrast, streamline the design-to-production cycle: HRB’s automated combined CNC lines have achieved a 63% faster design freeze for oven hinge components, accelerating PPAP (Production Part Approval Process) validation for its clients. This agility is critical for OEMs looking to respond quickly to market demands, and it is amplified by HRB’s full engineering support, which allows clients to refine their component designs within the same integrated workflow that handles production. For businesses partnering with HRB, this means getting custom CNC-machined and turned parts to market faster while maintaining the high quality that has made the company a trusted supplier to brands like Kenmore and Frigidaire.
