Precision Machining Parts Thread Technology

What are CNC precision machining parts? machining parts is an advanced manufacturing technology that uses computer programs to control machine tool processing parts. Name computer numerical control (CNC) technology. in CNC machining, our engineers through specific CNC programming software input part dimensions into the CNC machine control system.

MK CNC is a professional machining parts manufacturer, we use specialized CNC programming software (such as G-code or M-code) to create processing programs for the parts, these programs contain a series of instructions that the machine tool needs to execute, such as processing parts tool movement path, cutting speed, feed speed, etc. thereby processed precision machining parts, CNC machining technology is widely used in processing threads.

When producing precision machining parts, our engineers usually enter relevant instructions step by step into the CNC programming software according to the precision machining parts threads design requirements and processing steps.

Use the specific thread tools, these include thread tappers and thread milling cutters.

Thread tapping knife: thread tapping knife tools are used to cut internal threads in holes. the tools usually have thread shape, processing thread form for parts inside. thread taps can be divided into manual taps and mechanical taps.

Thread mill: the thread mill tools are specifically designed for processing external threads. the tool has special geometry processing parts’ external threads.

Thread cutting tool: This tool is usually used for thread cutting on CNC lathes or CNC milling machines.

Precision Machining Parts Manufacturer Processing Thread Standard

German DIN thread dimensions standard

Germany’s thread standards are mainly formulated and managed by the German Industrial Standards Association (Deutsches Institut für Normung, DIN for short).

DIN 13: This is a general thread dimension standard, that specifies thread parameters, such as pitch, diameter, thread profile, etc.
DIN 13-1: Contains general thread sizes and tolerances specifications, ensures threads processing according to specification requirements.
DIN 13-2: Includes threads specification standards, and specifies in detail threads’ dimensions and parameters.
DIN 405: This is the internal thread pipe connections standard, which specifies the relevant parameters and requirements for internal thread connections.
DIN ISO 228 1G3/8″: when producing precision machining parts, if the parts have thread dimension requests, we need to check the thread DIN ISO 228 G3/8″ standards.

The thread usually marks tolerances, such as ± 0.02. ensure the parts’ size and shape meet the design requirements, and ensure the assembly accuracy and reliability. then parts need a second processing, processing thread, CNC machining technology processes threads, and threads are an important key to connecting with other parts. therefore, the thread’s dimensions must be fully inspected. we use the thread gauge inspection thread, to confirm the thread accuracy. precise threads will prevent failure when assembled with other products. Our factory produces thread precision machining parts have been fully inspected, ensure there are no accidents when assembling the customer’s parts.

The DIN standards cover different types threads, including metric and imperial threads, it is widely used in engineering and manufacturing in Germany and other countries. following the thread standards ensures parts thread connection.

American Thread Dimension ANSI/ASME Standard

The thread standards in the United States are usually formulated and managed by the American National Standards Institute (ANSI) and the American Society of Mechanical Engineers (ASME). there are some common American thread ANSI standards.

ANSI/ASME B1.1: Unified English threads (UN and UNR thread forms)
This standard specifies unified and cylindrical thread manufacturing requirements, covering both UN and UNR thread forms.
ANSI/ASME B1.20.1: General Purpose Pipe Threads (Inches)
This standard specifies precision machining parts pipe thread design, dimensions, tolerances, and processing requirements
ANSI B1.13M: Metric thread: Type M
This standard specifies the dimensions, tolerances, and design requirements for type M metric threads.
ANSI B1.15: Unified Miniature Threads (UNM and UNF thread forms)
This standard covers the specifications and design requirements for unified miniature threads.

The ANSI/ASME standards cover different types of threads, including unified threads, pipe threads, miniature threads, and more. it is widely used in USA engineering and manufacturing. following thread standards helps ensure the thread matching connection.

French standard thread short name is NF. NF thread is a standard thread system in France, which may be slightly different from thread standards in other countries (such as ISO, UNC, UNF, etc.), so we need to pay attention to processing it. NF thread is usually used in precision machining parts produced in France.

Different countries use different thread dimension standards, and we should pay attention when analyzing drawings. MK CNC is a precision machining parts manufacturer, when processing thread, we analyze drawing thread dimensions standards. it is necessary to ensure that the threads meet the corresponding national standards. correctly understanding and following thread standards, ensuring processing high quality thread precision machining parts meets engineering requirements. based on the customer‘s drawings, our engineers will carefully review thread precision machining parts requirements. including parameters, such as pitch, diameter, tooth type, etc.

Determining the thread standard requirements. metric threads and imperial threads are two common thread standards. when analyzing the drawing, our engineers confirm whether the thread is metric or imperial, and then select the corresponding standard based on the specific requirements.

Metric thread standards usually adopt the ISO series, such as DIN ISO 228, the British thread standards may involve BSW and BSF. in addition, we analyze types of threads, such as internal or external, and the thread’s pitch and profile. for external threads, we need to pay attention to the pipe thread standard, like DIN ISO 228 1G3/8″, and external thread DIN ISO 228 AG1/2″.

When analyzing thread drawing dimensions, our engineers also consider other factors, such as tolerance requirements, surface treatment requirements, and thread processing technology. we are a rich experience precision machining parts manufacturer, please contact us!
