Precision Machining at Sheldon Precision

Posted by

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?

Posted by

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?

Posted by

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.

Manufacturing Precise Parts through CNC Machining

Posted by

CNC machining is a manufacturing process that features computer-directed machines to complete machining tasks while working with a wide range of materials. Similarly, manufacturing precision parts also means working with different materials, and different materials have different characteristics – this is when CNC machining comes into play.

For example ‘precious metals’ such as gold, silver and platinum tend to be “softer” or malleable metals, that require minute adjustments to create accurate precision parts. Comparatively, “harder” metals such as brass and copper, primarily used for conducting electricity, receive a different treatment to manufacture the precision parts. This is why CNC machining is so important in the Swiss Screw machining industry.

CNC MachiningManufacturing parts as small as a ridge on the edge of a U.S. dime requires a number of high quality components on our side. Sheldon Precision relies on CNC machining because it is more precise, and since it is implemented through a numerical code on a computer, the job will be completed to specification consistency throughout the manufacturing process and without “fatigue”, an issue that may arise in manual machining. Additionally, direction, location, and pace are monitored throughout the CNC machining process, and with knowledgable, experienced associates, we excel and Swiss precision CNC machining.

Supplying customers with the best precision machined parts is accomplished through the combination of CNC machining and cam driven Swiss Screw machines at Sheldon Precision. This is evident with the renewal of our ISO 14001 certification. A ISO 14001 certification displays a company’s responsible environmental management that promotes a cost-effective and efficient way of utilizing  tools.
