Computer numerical control (CNC) machining is a computer-aided manufacturing process used to create a wide range of parts and components for volumes ranging from prototyping through full-scale production. CNC machining is often the preferred method for manufacturing precision parts from aluminum. Aluminum is one of the most commonly used materials for its many favorable physical properties.
Properties of Aluminum Machined Components
Aluminum is generallya soft, durable, nonmagnetic metal with unique thermal and mechanical capabilities. Some of the beneficial properties of this material that make it a great choice for machined components include:
Ductility and malleability. As a highly malleable metal, aluminum is easily machined and relatively easy to shape and drill.
Versatility. There are a myriad of grades of aluminum and aluminum alloys, each designed with specific characteristics to meet differing needs.
Resistances. Aluminum features a variety of excellent resistances to corrosion and most chemicals. When exposed to air, a thin, protective layer of oxidation forms on the surface of the metal, protecting it from further oxidation. Aluminum is also highly resistant to harsh chemicals, including most acids.
Strength-to-weight ratio. Aluminum’s high strength-to-weight ratio makes it an ideal material for transportation applications. Aluminum alloys have the strength and durability needed for critical components, while the metal’s light weight reduces fuel consumption and emissions.
Conductivity. Aluminum has excellent thermal and electrical conductivity properties. Aluminum is commonly used for major power transmission lines and is an excellent material for heat sink applications, such as computers, that require heat to be drained away rapidly. Aluminum is also a good reflector of heat and visible light, making it useful in lighting applications.
Non-toxic. Aluminum is a non-toxic, odorless metal, which makes it popular for use in pharmaceutical and food production.

Swiss turning and traditional Computer Numerical Control (CNC) turning are two different ways used to machine parts made of metal or other raw materials. Specifically, machining is the process of removing material from a workpiece and shape it into its intended design. Both Swiss turning and CNC turning function by spinning materials at high speed and using cutting tools to shape the material into the desired part. This practice has been around for many years but has become more versatile with new technologies. These practices are crucial to many different industries for their ability to engineer metal and plastic parts efficiently and precisely.
In this post, we will give you information regarding:
Conventional CNC turning what it is, how it can be applied, and why it is useful
Swiss CNC turning what it is, how it can be applied, and why it is useful
Comparative advantages: what these processes have in common and how they are useful to your industry
Which type to use how the advantages of these practices apply to you
What Is Conventional CNC turning?
Conventional CNC Turning is a process in which the bar stock rotates in a fixed position and the cutting tool’s position is driven by servo-controlled motors, typically in the X and Z axes. The process allows for highly accurate movements. Commercial metalworking machines feature standard closed-loop controls that provide accuracy, speed, and durability.
Advantages and Features of Conventional CNC Turning:
This type of conventional turning is better suited for shorter, large-diameter parts with tight tolerances or difficult materials. It is ideal for many applications including:
Anything with a diameter larger than ¾ inch
What Is Swiss CNC turning?
Swiss CNC turning is a process that feeds rotating bar stock through a guide bushing. No matter how long the workpiece, the turning tool always cuts the stock near the bushing or the point of support. The machine then feeds this past the spindle and past the tool as it goes, making Swiss-type effective for long and slender turned parts.
Advantages and Features of Swiss CNC Turning
Swiss CNC turning has an advantage in that during the turning process, the material is supported close to the tools cutting it. Using a guide bushing, the workpiece is pushed through and into tools while preventing deflection of the workpiece.
Some ideal applications for Swiss screw machining are:
Long parts and small-diameter parts under 0.750 in.
If you need something with minimal bending or your project has high volumes of small, cylindrical pieces with extremely tight tolerances, then Swiss CNC turning would be the best process for you. On the other hand, Conventional CNC turning offers high repeatability, precision, versatility, and speed manufacturing.

Industries around the world are turning to robotic machinery as they seek to reap the benefits of the fourth industrial revolution. Robotics make production processes more efficient, safer, and more cost-effective while reducing waste. Even facilities with existing automation technology can realize new benefits as robots become more intelligent and capable of handling multiple tasks.
Let’s take a closer look at the advantages robotic machinery can provide to your production facility.
Consistent High Quality Production
A guarantee of consistent quality is one of the most significant benefits offered by robotic machinery. Human operators may become tired or lose focus over the course of a shift, but robots will follow the same production orders repeatedly without variations in quality or accuracy.
Smarter, more integrated robots can also monitor the workpieces through the product cycle to check for errors and adjust their processes to compensate.
As robotic machinery continues to evolve, it takes on more tasks with less need for human intervention between each stage. For example, a completely automated process will move workpieces from one machine to another, properly place it for the next step, and inspect the finished piece for quality concerns.
CNC machinery and multi-purpose robots can produce goods using a variety of different tools and processes. Instead of having one robot that follows one unchanging set of directions per task, modern robotic machinery can fluidly change from one step to the next. Ultimately, robotics improve product quality by reducing defect rates and offering consistently reliable performance.
Decreased Production Costs
Robotic machine tending noticeably reduces production costs in two ways:
Per-unit efficiency. Robots reliably produce goods with fewer errors. More comprehensive robotic setups can remove any risk of human error entirely. This lowers the per-unit cost of a production run. Even better, machinery can process raw goods and workpieces more precisely, resulting in less waste and tighter material estimates.
Facility efficiency. Robots reduce the production costs of an overall facility. They can work 24/7 without flagging or pausing without incurring the same labor costs and overhead as human employees, such as health insurance, liability insurance, wages, and other costs. Facilities can increase production without increasing staff size, which in turn lowers administrative and HR costs.
Lights-out or dark factory manufacturing underlines this key benefit of robotic machine tending. Robots can operate without direct human oversight, so facilities can extend production hours through the night. Even better, the facilities don’t need to maintain the same conditions as human-operated facilities: the lights can be out, climate control can be adjusted to meet ideal production standards without catering to human comfort, and the facility has greater energy efficiency.
Many facilities, rather than operating on a continual lights-out basis, use the lights-out mentality between shifts so humans can reset the machine programs and move finished products off the factory floor. As robotic machinery continues to develop, these “lights-on” intervals will become increasingly unnecessary.
Multiple Specialized Machining Operations
As machinery becomes more complex and can learn larger sets of increasingly specialized skills, they can take on more tasks commonly reserved for skilled human employees. A complex robotic system can handle a variety of tasks, including:
Using advanced robotic machinery that can handle multiple tasks doesn’t just give production companies the ability to add more services to their lists of offerings. Single robotic stations that can handle multiple tasks help to optimize in-demand floor space in a production facility.
Companies that invest in multi-functional robotics will realize financial benefits both immediately and in the long run over the life of the robotic systems.
Limit Hazardous Environment Exposure For Human Workers
Liability poses one of the largest risks for any manufacturing operation—specifically, the risk of injury to human employees in dangerous environments. Field production sites can be hazardous, unpredictable, and may expose human workers to dangerous chemicals or other environmental factors. Even controlled environments such as warehouses and distribution centers pose a large risk for companies due to the risk of repetitive stress injuries and workplace accidents.
Robotic machinery works unimpeded in potentially dangerous environments. Reducing or eliminating manual labor at industrial worksites is a great way to reduce overall expenses, legal liability, and associated healthcare costs.
Robotic Machine Tending at Hogge Precision
Robotic machine tending isn’t just a niche development for highly specialized production centers. It’s an integral part of the fourth industrial revolution and an accessible improvement for every production facility. Investing in robotics can increase production quality, reduce expenses, increase manufacturing capabilities, and reduce the risk of employee injury.

When Should I Use Multi-Axis CNC Machining?
Multi-axis machining is a highly versatile manufacturing process suitable for use in a variety of industrial and commercial projects. It is particularly useful for the following machining needs:
1. Machined Parts with Medium to Complex Geometry
Some industries—such as aerospace, automotive, medical, mold and die, and oil and gas—employ parts and products with highly complex shapes, geometries, and surfaces. The manufacture of these components—e.g., impellers, turbines, and steering parts—necessitates the use of multi-axis machining as the process accommodates machining operations on 4-5 axes and can produce the highly specific part angles necessary.
2. Flexible Engineering Solutions
The versatility of the multi-axis machining process makes it well-suited for use in industries that require design flexibility, such as aerospace and mold and die manufacturing. In these industries, design engineers need to create parts and products to suit highly complex systems and applications. Multi-axis machining provides them with a manufacturing solution that can accommodate these more complicated designs.
3. Low-Volume, High-Mix Production
Many industries are turning away from large volume production orders to repeat orders of smaller quantities. Multi-axis CNC machining lends itself to this business practice as parts can be produced quickly to meet changing customer demand reducing the risk of excessive inventory.
4. High Precision, Accuracy, and/or Complexity Workpieces
The multi-axis machining process is ideal for industries that require high-precision, high-complexity parts, such as the aerospace, automotive, electronics, medical, and semiconductor industries. It can produce durable parts that meet high quality, accuracy, and performance standards. The use of computerized controls and tooling ensures that the parts produced fit the required specifications and remain consistent from one piece to the next and between batches.
5. Projects Requiring Reduced Lead Times and Improved Efficiency
Some machining projects have tighter time constraints or more thorough efficiency requirements than others. As the multi-axis CNC machining process can perform multiple operations with a single setup, it can significantly reduce downtime and improve overall lead time.
Benefits of Using Multi-Axis CNC Machining
Compared to other machining and manufacturing processes, the multi-axis CNC machining process offers a broad range of benefits, such as:
Faster manufacturing operations

Types of Swiss Screw Machines
There are two main types of Swiss screw machines in use today.
Automatic Swiss screw machines use a disc cam to rotate tools toward the workpiece area, which is held in place with several spindle collets positioned side by side. Computer Numerically Controlled (CNC) machines use a CNC unit to control the tools, which allows parts to be made to exacting specifications. CNC Swiss screw machines, which are also known as CNC lathes, can work on multiple axes for fast results.
Screw machines, both automatic and CNC driven, can take some time to set up properly, but are cost effective when producing multiple parts. They are typically not an ideal solution for one-off prototyping. However, because of the wide variety of metals they work with, they are a flexible choice when creating parts from different types of metals.
Benefits of the CNC Swiss Machine
CNC machining offers a level of control that may not be possible with an automatic Swiss screw machine. The CNC unit permits the use of tools on multiple axes, allowing more sets of tooling for both turning and milling. Cycle times are reduced and more detailed parts can be created with the use of CNC abilities.
Many operations can be performed in a shorter period of time using a CNC Swiss machine. A CNC Swiss screw machine can rotate a part at up to 10,000 RPM with an accuracy level of 0.0002 to 0.0005 inches. In addition to being more precise, a CNC Swiss lathe reduces waste and gives more flexibility when machining a specific part.
Using Automatic and CNC Swiss Screw Machines
Both automatic and CNC Swiss screw machines cost effectively produce multiple small, turned parts for a variety of industries. Hogge Precision uses numerous Swiss-style turning lathes to create small diameter parts from most types of metal. We can run metal bar stock up to 12 ft. long and 1.25 in. in diameter and meet tolerances as tight as ±.0005 in.
Hogge Precision serves a wide range of industries including defense, energy, medical, power distribution, and other industrial applications. Parts we have successfully manufactured using swiss style screw-machining include brass, aluminum, and stainless steel components for IT and Electrical; brass and stainless steel components for Medical; and aluminum and stainless steel products for the Automotive industries.
