Precision CNC Swiss Machining Services

cnc machiningCNC machining is already a powerful manufacturing technique for crafting components with extremely tight tolerances. Thanks to programmed, computer-guided motions, CNC processes can achieve consistent results that outperform even the most skilled human operator.

Swiss machining improves even further on CNC turning through the addition of a guide bushing, which enables the manufacture of longer components and provides multiple additional axes of control. As a result, a Swiss-style turning machine can create the same component as a traditional turning machine in a fraction of the time by reducing multiple operations down to one operation.

McCormick Industries is an ISO 9001:2015-certified company specializing in precision machined components. Our services extend from standard CNC turning and milling to also include Swiss machining for jobs requiring the utmost precision. Thanks to our expertise in this area, we’ve come to be known as a reputable provider for industrial, aerospace, defense, and medical machining, among others.

Precision Machining Services at McCormick Industries

At McCormick Industries, we continually invest in equipment and machinery that grants us advanced precision manufacturing capabilities. We specialize in Swiss-style machining, as well as more traditional precision CNC processes.

cnc swiss latheSwiss Turning and Machining

Our cutting-edge facility is stocked with multiple Swiss-style turning centers with advanced capabilities. Using these machines, we can achieve ultra-precise dimensional tolerances within ±0.0001 inches and cycle times as low as 10 seconds. These machines boast nine axes of machining motion, making it possible to perform multiple tasks in a single cycle.

Swiss machining also saves time by enabling lights-out machining, which means the work centers can operate unattended for extended periods of time. This is possible thanks to a combination of automated feeding and handling, all monitored by reliable control software. As a result, Swiss machining drastically increases production volume while minimizing labor costs. Our Swiss machining production services are available for components with diameters up to 1.25 inches and are compatible with virtually all common metals and plastics.

CNC turning toolingCNC Turning

We also use traditional CNC turning methods, especially when we need to accommodate larger component sizes than our Swiss machines can handle. Our CNC turning centers are suitable for components up to 18 inches in length with diameters up to 1.625 inches. McCormick has been providing high-quality turned components for over 20 years, constantly drawing on the latest innovations in machining technology. By employing only cutting-edge machinery and knowledgeable operators, we’ve consistently provided tolerances as tight as ± 0.0001″ on length and diameter and ±0.00008″ on roundness.

CNC millCNC Milling

Our final area of expertise is CNC milling, which is known for producing parts with extremely tight tolerances. Milling uses rotating cutting tools to shape the workpiece, whereas turning rotates the workpiece itself. We employ a variety of vertical milling centers (VMCs) with high-speed spindles reaching 12,000 RPM to ensure rapid and accurate production of milled components. Our expert operators take care to set up the machinery with the best tool for each given task, resulting in tolerances as tight as ±0.0003 inches for surface features while still maintaining rapid turnarounds.

Our milling capabilities include a full range of metals and plastics in both high- and low-volume runs. We also offer a variety of finishing options, such as micro-deburring, to ensure that your components are finished to your exact specifications.

Industries Served by Swiss Machining

Swiss machining is an ideal option when components must meet exacting tolerances for straightness or concentricity. Such requirements are common in industries such as medicine or military operations, where any deviations in a component’s size could put human lives at risk. These needs are also found in industries that work with small or delicate electrical components.

McCormick Industries has a great deal of experience serving a broad range of industries. Here are some of the sectors we most commonly work with:

Industrial

Industrial components are a special kind of CNC challenge, requiring tight tolerances on small components. Before Swiss machining, the set-up for such orders was labor-intensive and error-prone. However, with the precise multi-axis motions of a Swiss-style turning machine, we are able to navigate these challenging projects with ease.

Our production case study serves as an excellent example of our capabilities in this area. We served as the primary contractor for the product, which was a 0.472 inch long, 0.118 inch in diameter dowel pin custom-manufactured for a product used in the electromechanical industry.

We determined that Swiss machining would be the best tool for primary processing, and we chose a machine with high-pressure cooling capabilities to remove chips and maintain a sharp edge on the cutting tools.  Leveraging this technology, we were able to exceed typical processing speeds while still producing a reliable, high-quality product.

Welding Components

Welding components often have similarly rigorous design constraints. One of our longstanding customers in the welding sector trusted us with the manufacture of a gas lens for use in TIG welding. Lenses of this type must conform to very specific measurements because they regulate gas flow for the welding machine. This particular design also called for complicated design features, including cross holes and stamped markings.

To create this component, we programmed a Swiss machining center to drill, mill, and stamp the workpiece, using the machine’s high-pressure cooling system to enable more efficient processing. We also took advantage of the Swiss-style center’s multi-tool, multi-axis capabilities to combine multiple machining steps into each pass.

Medical

Surgical instruments must be manufactured to perfection. Even the most minor aberration in the surface finish of a medical device can harbor bacteria, potentially resulting in serious infections. This was the challenge for one of our medical projects, a surgical mallet staff with complicated design features like flanges, fillets, and grooves.

We used a high-performance grade of stainless steel for the project, which we machined using Swiss-style turning centers to achieve the precise tolerances demanded by our medical clients. Using these CNC techniques, we managed tolerances of ±0.002 inches for the diameter. Once formed, we performed all sanding and polishing necessary to achieve a completely smooth surface free of dangerous nicks or abrasions.

Aerospace and Defense

Our customers in the aerospace and defense industries are known for demanding absolute precision and consistency. In this instance, a supplier we’d worked with before returned to us to craft a complicated military trunnion. The design called for close tolerances with complex geometric and surface features. We determined that Swiss machining would allow us to fulfill these requirements while keeping the turnaround time and budget requirements under control.

Using our Cincom K 16E center, which offers a large and flexible tool capacity, we achieved ±0.0001 inch tolerances, verified by on-machine vision inspection followed by caliper and micrometer measurements. We were able to maximize speed, accuracy, and repeatability using Swiss machining to keep costs down.

Advantages of Swiss Machining

CNC machining on its own is a powerful tool, but Swiss machining improves performance on many of the key metrics that our clients care about. The benefits of Swiss machining include:

  • Cost savings. A typical Swiss-style center can complete both milling and turning at the same time, incorporating multiple tools and axes of motion. This minimizes labor costs as the machines require little intervention once set.
  • Precision. Swiss machining offers maximum precision with dimensional tolerances as low as ±0.0001 inches. This is a key benefit for industries that demand accuracy and repeatability above all else.
  • Speed. A Swiss center performs multiple tasks in a single pass, which drastically reduces cycle times and increases production volume. Also, since Swiss centers can operate lights-out, we are able to produce components near-continuously, further reducing lead time.
