Variations between Thread Whirling Milling and Thread Milling

Side Thread Whirling Milling Thread Milling
Definition A high-speed technique for milling threads, utilizing specialised, high-efficiency thread processing machines or gadgets. Normally carried out on thread milling machines, utilizing both disk-shaped or comb-shaped milling cutters.
Effectivity Excessive processing effectivity, which might improve effectivity by greater than ten instances in comparison with conventional strategies. Effectivity could not match that of whirling milling.
Accuracy Excessive processing accuracy, with the floor roughness reaching Ra0.8 microns. The pitch accuracy can typically attain stage 8 to 9, and the floor roughness is R5 to 0.63 microns.
Process The product is fashioned in a single cross with out the necessity for knife withdrawal and eccentric reducing. Requires a machining middle with three-axis linkage (or above) with spiral interpolation operate.
Utility Extra favored in large-scale manufacturing attributable to its excessive effectivity and one-pass formation. Could also be extra economical by way of gear and gear prices, particularly for small-scale manufacturing or diversified thread specs.
Value The price of gear and instruments could also be increased attributable to its excessive effectivity. Could also be extra economical by way of gear and gear prices.

Each thread whirling milling and thread milling have their benefits. The selection of the appropriate technique is determined by the particular processing wants, effectivity necessities, accuracy requirements, and value issues. The kind of thread, the traits of the processing materials, and the dimensions of manufacturing ought to be considered when making a choice. By selecting the suitable processing technique, the standard of thread processing might be ensured, whereas maximizing cost-effectiveness.

Processing Ideas

Thread Whirling Milling

Thread whirling milling is a particular processing technique that makes use of a singular device. It processes threads by axially feeding whereas rotating at excessive velocity. The attribute of this technique is as soon as fashioned, no want for a number of reducing, therefore, it has excessive processing effectivity and accuracy.

Thread Milling

Thread milling, alternatively, makes use of a ball-end mill or an finish mill. It processes threads by programming to manage the shifting trajectory of the device. The attribute of this technique is its potential to process threads of assorted specs, providing excessive flexibility, however it could require extra processing time.


Processing Traits

Processing Methodology Processing Pace Processing Accuracy Processing Value Relevant Scope
Thread Whirling Milling Quick Excessive Excessive Appropriate for processing lengthy threads, deep threads, and multi-start threads
Thread Milling Gradual Medium Low Appropriate for processing quick threads, shallow threads, and single-start threads

Comparability of Advantages and Disadvantages

Processing Methodology Advantages Disadvantages
Thread Whirling Milling Quick processing velocity, excessive processing accuracy, quick chips, lengthy device life Excessive processing price, excessive gear necessities, advanced programming
Thread Milling Low processing price, low gear necessities, easy programming Gradual processing velocity, medium processing accuracy, lengthy chips, quick device life

Choice information: Comparability of spiral and thread milling

When choosing the thread machining technique, it’s essential to comprehensively think about the elements comparable to processing effectivity, accuracy, price and thread sort. This is a information primarily based on the most recent analysis that can assist you make the fitting alternative.

Processing effectivity

Spiral milling: with extraordinarily excessive processing effectivity, the velocity can attain 400 meters per minute, which is a number of instances and even ten instances that of conventional turning processing. Thread milling: Though extra environment friendly, however in comparison with cyclone milling, its processing velocity is slower.

Machining accuracy

Spiral milling: As a result of one-tool forming and eccentric reducing don’t must withdraw the device, the processing accuracy may be very excessive, and the floor roughness can attain Ra0.8 microns, which is 2 ranges increased than the normal processing technique. Thread milling: can even acquire good machining accuracy management, appropriate for top precision necessities of the workpiece.

Processing price

Spiral milling: Though the gear price is increased, however as a result of there is no such thing as a want to alter the lathe construction, simple set up, saving the price of funding in particular machine gear. Thread milling: requires the usage of a 3-axis CNC machine device, the associated fee is decrease than the faucet, however a single thread milling cutter is dearer than the faucet.

Thread sort

Rotary thread milling: appropriate for processing lengthy thread, deep thread, multi-thread, the device adopts a convertible blade, might be utilized to a wide range of pitch thread reducing. Thread milling: Broad utility vary, can process a wide range of working situations of thread, appropriate for brief thread, shallow thread, single thread.

Different issues

Spiral milling: has a excessive diploma of automation, can obtain totally computerized processing. Thread milling: good device versatility, excessive processing security, even when there’s a damaged knife won’t damage the parts. Nevertheless, the programming is comparatively troublesome, which limits its large utility.


Spiral milling has apparent benefits in processing effectivity and accuracy, and is appropriate for machining advanced thread sorts, however at a better price. The thread milling price is low, the applying vary is large, however the effectivity and accuracy are barely inferior. Your alternative ought to be primarily based on the particular processing wants and value funds.
