CNC Technology and Swiss Precision Machining

As a type of lathe, Swiss machines have been used for more than 100 years to manufacture with accuracy. The term “Swiss” in machining actually has more than one meaning. To some it is a type of machine, and to others it represents a product of uncommonly small size or high precision. To us at Sheldon Precision, the use of this term allows us to be absolutely certain of the meticulousness of your desired product.

Computer numerical control, also known as CNC is the self-operating control of commonly used machining tools such as drills and lathes by the use of a computer. This equipment can take any material and perform a wide range of manufacturing tasks such as cutting, or drilling that meets specifications programmed into it’s software which requires little-to-no man power.

Positioning CNC as a computer-controlled process, CNC Swiss machining has only gotten better as a unique tool and is being used in a growing number of industries and applications.

Sheldon Precision utilizes CNC technology, as well as precision machining, along with Computer Aided Manufacturing programs to produce both large and small quantities of precise parts. Our product ranges from sizes .015” to up to 1.125” in diameter. Considering the microscopic size of the product, it is crucial to use the CNC technology in order to ensure perfect accuracy of fit.

From Turret Lathe to Modern Day Swiss Screw Machine

While Sheldon Precision has been manufacturing precision machined components since 1969, Swiss Screw Machining dates way back to the mid-1800s. In America, Joseph R Brown patented a machine for cutting spills and coined the term “screw machine”. His screw machine was an improvement on the turret lathe, a machine used to make several tools at once. 

At the same time, the Swiss were developing a similar machine to be used for watchmaking. 

A few years later in 1880, the first fully automated screw machine was made by the engineers at Brown and Sharpe, led by Oscar S. Beale.  

Finally, from the 1940-50s, engineers developed the technology we know today as CNC, Computer Numerical Controlled technology. Once developed, they were able to make the first CNC Swiss screw machines in the 1970s. While it was first used in electronics and the semiconductor industry, by the 1990s they had also done extensive work within aerospace, healthcare, and industrial applications. 

As a company, we use CNC Swiss Screw machines heavily in our work with aerospace applications. Using state of the art machinery and skilled operators, we turn our precise components in a variety of materials, including steel, stainless steel, aluminum, brass, copper, and titanium.

Precision Machining at Sheldon Precision

Precision machining is a process used to remove material from a workpiece while holding close tolerance finishes. It is a type of machining that shapes large pieces and sometimes small pieces of material into smaller complex parts so they fit exactly where they need to be to perform a specific task.

At Sheldon Precision, we have the capability to produce both large and small objects that are used in several different industries. From the production of surgical tools to artillery components, different controls and valves to electronics, precision machining reaches every industry.

Sheldon Precision’s capabilities include many machine types such as milling, turning and electrical discharge machining. Producing complex objects requires different levels of machinist skills in order to precisely manufacture each piece. A professional, highly-trained and experienced machinist follows a specific blueprint of the object for quality precision.

These blueprints are made by CAD (computer aided design) or CAM (computer aided manufacturing) programs. CAD and CAM programs are software programs that produce three dimensional outlines necessary for manufacturing the object. Not only does precision machining design and cut different metals, it may also work with graphite, glass and plastics.

To produce quality and accurate objects, CNC (computer numerical control) programming is used to follow exact dimensions throughout the run of a product. The cutting tool is directed to make the necessary cuts with specific cutting speeds. Each cut is supervised by an expert machinist to produce high quality and accurate parts. Quality inspection and control is a critical step in the precision machining process. This ensures the parts are being manufactured to exact specifications consistently.

At Sheldon Precision, you’ll find a quality team of experienced engineers and machinists along with an arsenal of sophisticated manufacturing machinery and quality assurance systems.

Why You Should Swiss Machine Your Plastic Components?

Sheldon Precision understands that the integrity of a precise machined part begins with using high quality materials. When using Swiss machines more material options are available to manufacture than in injection molding. Not only can Swiss machines manufacturer aluminum, copper, and steel, they also can manufacture plastic components as well.

CNC Swiss machines work with the right tooling speeds to overcome temperature restrictions experienced when working with thermoplastics or thermosetting polymers. At Sheldon Precision, we specialize in machining any material suitable for CNC Swiss machines. The elasticity of our CNC Swiss machines allows you to choose any material for your next design. We are able to manufacture plastic components with accuracy and optical clarity.

CNC Swiss machines can reach ultra-high tolerance, down to 0.0002” which is implausible for injection molding processes. Set up and tooling costs are more cost-effective than mold development for short to medium runs. This is very helpful for companies who rely on just-in-time shipping, that need to oversee their supply chain at a very granular level. Swiss machines are able to control fluctuating production volumes when inventory is not wanted. Swiss machining is the most efficient choice when working with small complex components.

A major problem when working with injection molding is it can leave weld lines, parting lines, gate markers, and ejector pin marks. This problem requires additional maintenance to complete the part. However, CNC Swiss machining does not require any post fabrication finishing because it does not leave unwanted marks. This feature in CNC Swiss machining can dramatically decrease the cost-per-part. In addition, infusing molten plastic in the small gaps of a mold might be close to impossible because there is no correct balance of material temperature and injection pressure to eliminate the resistance to the plastic flow.

At Sheldon Precision, we manufacture plastic parts for a variety of industries such as medical, dental, electronics, and military. With our experience in fabrication and design, we can help you determine the best plastic material for your part.

What is CNC Turning?

What Is CNC Turning?
Computer Numerical Control (CNC) is an intricate method for creating parts using a lathe. This method is used to create detailed patterns in metals that are difficult to do by hand. CNC turning is computer controlled to precisely cut materials into a final product. This process is able to create accurate cylindrical cuts to produce circular/tubular parts. The CNC machine cuts to ensure accuracy so the products are mass produced into precise, complexed designs.

How Does It Work?
The CNC Turning engineer decides on which cutting tools to use to set up the lathe. The engineer also chooses a clamping method to hold the material firmly in place. Next, the engineer works with the computer to tell the lathe machine to move and cut parts.
This is where the skills come in. The engineer pays attention to make sure the lathe is cutting the material properly. In order to successfully match the dimensions the engineer may use a blueprint to cut with precision.
After the material is cut, the part is sent to be assembled.

How Is CNC Turning Different From CNC Milling?
The main difference between the two procedures is the final product they create. CNC milling is computer controlled by a G-code that controls the speed and location of the movements. However, this procedure may also be performed by manual override in order to adjust the process if necessary. The machine can cut a variety of shapes moving along multiple axes. The main responsibility of CNC turning is to cut tubular parts using a single-point cutting tool inserted parallel into the material.
