Insulation parts

    Insulation parts
    As a professional manufacturer of insulation parts. Our factory is equipped with 3,4 and 5-axis machining on a range of 

CNC Milling machines. One of our advantages is that we are not only offering insulation tube or [url=http://www.jy-

insulation.com/insulation-rod/]insulation rod[/url]， but also secondary machining service for our customers. Therefore, we 

can help on cost down and shortening lead time. 

    Learn about the following insulation parts:

    Epoxy Glass Tube

    Epoxy Glass Tubes are highly economical insulating tubes that offer a combination of excellent mechanical strength and 

good electrical performance. Like our Epoxy Glass Rods, our Epoxy Glass Tube is capable of withstanding continuous 

temperatures up to 130oC (though other grades of material, such as our Isoval Tube, with higher temperature 

ratings are also available upon request).

    The combination of electrical performance and mechanical strength offered by our [url=http://www.jy-

insulation.com/insulation-tube/epoxy-glass-tube/]epoxy glass tube[/url] allows them to often be utilised in the manufacture 

of insulating bushings as well as insulating sleeves. Yellow in colour, our Epoxy Glass Tube can be machined to tight 

tolerances and thin wall thicknesses.

    Epoxy Fiberglass Rod

    12 foot long epoxy fiberglass rod 11 16 

diameter is made of high strength aramid fiber and glass fiber, impregnated with epoxy resin by pultruding under high 

temperature. It has ultra-high strength, excellent wear resistance, acid and alkaline resistance, corrosion resistance and 

other excellent high temperature performance characteristics. It is suitable for electrolytic aluminum plant, steel works, 

high temperature metallurgical equipment, ultra-high voltage electrical equipment, aerospace and aerospace fields, 

transformers, capacitors, reactors, high voltage switches and other high voltage electrical appliances.

    CNC machining is a term commonly used in manufacturing and industrial applications. But exactly what is CNC? And what 

is a CNC machine?

    CNC 101: The term CNC stands for 'computer numerical control', and the CNC machining definition is 

that it is a subtractive manufacturing process which typically employs computerized controls and machine tools to remove 

layers of material from a stock piece—known as the blank or workpiece—and produces a custom-designed part. This process 

is suitable for a wide range of materials, including metals, plastics, wood, glass, foam, and composites, and 

finds application in a variety of industries, such as large CNC machining, machining of parts and prototypes for 

telecommunications, and CNC machining parts, which 

require tighter tolerances than other industries. Note there is a difference between the CNC machining definition and the 

CNC machine definition- one is a process and the other is a machine. A CNC machine is a programmable machine that is 

capable of autonomously performing the operations of CNC machining.

    Subtractive manufacturing processes, such as CNC machining, are often presented in contrast to additive 

manufacturing processes, such as 3D printing, or formative manufacturing processes, such as liquid injection molding. 

While subtractive processes remove layers of material from the workpiece to produce custom shapes and designs, additive 

processes assemble layers of material to produce the desired form and formative processes deform and displace stock 

material into the desired shape. The automated nature of CNC machining enables the production of high precision and high 

accuracy, simple parts and cost-effectiveness when fulfilling one-off and medium-volume production runs. However, while CNC 

machining demonstrates certain advantages over other manufacturing processes, the degree of complexity and intricacy 

attainable for part design and the cost-effectiveness of producing complex parts is limited.

    While each type of manufacturing process has its advantages and disadvantages, this article focuses on the CNC 

machining process, outlining the basics of the process, and the various components and tooling of the CNC machine 

(sometimes incorrectly known as a C and C machine). Additionally, this article explores various mechanical CNC machining 

operations and presents alternatives to the CNC machining process.

    Overview of CNC Machining Process

    Evolving from the numerical control (NC) machining process which utilized punched tape cards, CNC machining is a 

manufacturing process which utilizes computerized controls to operate and manipulate machine and cutting tools to 

shape stock material—e.g., metal, plastic, wood, foam, composite, etc.—into custom parts and designs. While the CNC 

machining process offers various capabilities and operations, the fundamental principles of the process remain largely the 

same throughout all of them. The basic CNC machining process includes the following stages:

    Designing the CAD model
        
    Converting the CAD file to a CNC program
        
    Preparing the CNC machine
        
    Executing the machining operation

    CAD Model Design

    The CNC machining process begins with the creation of a 2D vector or 3D solid part CAD design either in-house or by 

a CAD/CAM design service company. Computer-aided design (CAD) software allows designers and manufacturers to 

produce a model or rendering of their parts and products along with the necessary technical specifications, such as 

dimensions and geometries, for producing the part or product.

    Designs for CNC machined parts are restricted by the capabilities (or inabilities) of the CNC machine and tooling. For 

example, most CNC machine tooling is cylindrical therefore the part geometries possible via the CNC machining process are 

limited as the tooling creates curved corner sections. Additionally, the properties of the material being machined, tooling 

design, and workholding capabilities of the machine further restrict the design possibilities, such as the minimum part 

thicknesses, maximum part size, and inclusion and complexity of internal cavities and features.

    Once the CAD design is completed, the designer exports it to a CNC-compatible file format, such as STEP or IGES.

    CNC Machining Tolerances Tables

    When specifying parts to a machine shop, it's important to include any necessary tolerances. Though CNC machines 

are very accurate, they still leave some slight variation between duplicates of the same part, generally around + or - .005 

in (.127 mm), which is roughly twice the width of a human hair. To save on costs, buyers should only specify tolerances in 

areas of the part that will need to be especially accurate because they will come into contact with other parts. While 

there are standard tolerances for different levels of machining (as shown in the tables below), not all tolerances are 

equal. If, for example, a part absolutely cannot be larger than the measurement, it might have a specified tolerance of 

+0.0/-0.5 to show it can be slightly smaller, but no larger in that area.
