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 insulation rod， 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

epoxy glass tube

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.
