Common types of cutting tools for centerless lathes

Youdaoplaceholder0 cylindrical turning tool ‌

 

Youdaoplaceholder0 Features ‌ : Mainly used for turning the outer cylindrical surface of workpieces, the blade shapes are diverse, with common ones including rhombic and square. The rigidity of the tool holder is relatively good and it can withstand a large cutting force.

 

Youdaoplaceholder0 application scenarios ‌ : Suitable for processing the outer circles of various shaft and sleeve parts, and can perform rough turning, finish turning and other precision processing. For example, processing the outer circles of parts such as motor shafts and transmission shafts.

 

Youdaoplaceholder0 internal hole turning tool ‌

 

Youdaoplaceholder0 features ‌ : It is used for processing the inner holes of workpieces. The tool head part is relatively thin to allow it to extend into the hole for cutting. There are two types of blades: welded and machine-clamped. Machine-clamped blades are easy to replace and can improve production efficiency.

 

Youdaoplaceholder0 application scenarios ‌ : It can process various through holes and blind holes, such as cylinder holes in engines and oil cylinder holes in hydraulic systems, etc.

 

Youdaoplaceholder0 cutting knife ‌

 

Youdaoplaceholder0 features ‌ : The cutting edge is relatively narrow and is mainly used for cutting workpieces or dividing workpieces into the required size. The strength requirement for the cutting knife is relatively high to prevent breakage during the cutting process.

 

Youdaoplaceholder0 application scenarios ‌ : It is often used to cut long bar stock into short stock of a certain length, or to cut unnecessary parts during processing, such as cutting off the excess parts on shaft parts.

 

Youdaoplaceholder0 thread cutter ‌

 

Youdaoplaceholder0 Features ‌ : It is divided into external thread cutters and internal thread cutters, and is used for processing the external and internal threads of workpieces. The shape of the blade is designed based on the tooth profile of the thread, enabling precise cutting of threads that meet the standards.

 

Youdaoplaceholder0 application scenarios ‌ : It can process various common threads, pipe threads, etc., such as processing threads on pipe connectors, bolts and other parts.

 

Youdaoplaceholder0 drill bit ‌

 

Youdaoplaceholder0 features ‌ : It is used for drilling holes in workpieces. Common types include twist drills and center drills, etc. The cutting part of the twist drill has two main cutting edges and one cross edge, which can efficiently remove materials.

 

Youdaoplaceholder0 application scenarios ‌ : suitable for processing holes of various diameters, such as installation holes and positioning holes on mechanical parts.

 

Youdaoplaceholder0 milling cutter ‌

 

Youdaoplaceholder0 Features ‌ : In through-feed machines, milling cutters are mainly used for milling planes, grooves, etc. Common types include end mills and end mills, etc. The side cutting edge of an end mill can be used for milling planes, and the end cutting edge can be used for milling grooves.

 

Youdaoplaceholder0 application scenarios ‌ : It can process some parts with planar or grooved features, such as the tooth grooves of gears, planes on boxes, etc.

 

The processing range of the through-spindle machine

 

Youdaoplaceholder0 In terms of materials ‌

 

Youdaoplaceholder0 Metal materials ‌ : Capable of processing various common metal materials, such as steel (carbon steel, alloy steel, etc.), cast iron, and non-ferrous metals (aluminum, copper, etc.). For metal materials of different hardness and toughness, efficient processing can be achieved by choosing appropriate cutting tools and cutting parameters. For instance, when processing alloy steel with high hardness, hard alloy tools can be selected and the cutting speed can be appropriately reduced.

 

Youdaoplaceholder0 Non-metallic materials ‌ : Some through-feed machines can also process some non-metallic materials, such as plastics, nylon, etc. When processing non-metallic materials, the selection of cutting tools and cutting parameters are different from those for metallic materials, and usually a higher cutting speed is required.

 

Youdaoplaceholder0 Shape aspect ‌

 

Youdaoplaceholder0 rotating body parts ‌ : The through-feed machine is most suitable for processing rotating body parts, such as shafts, sleeves, discs, etc. These parts feature rotational symmetry. The through-spindle machine can process the parts through the rotation of the spindle and the feed motion of the tool. For instance, various shaft parts of different diameters and lengths can be processed.

 

Youdaoplaceholder0 complex-shaped parts ‌ : Some advanced through-feed machines have multi-axis linkage functions and can process some relatively complex shapes, such as parts with features like threads, holes, and grooves. For instance, shaft sleeve parts with both internal and external threads can be processed.

 

Youdaoplaceholder0 In terms of accuracy ‌

 

Youdaoplaceholder0 Dimensional accuracy ‌ : The through-feed machine can achieve relatively high dimensional accuracy, generally reaching IT6-IT7 grade, and some high-precision through-feed machines can even reach IT5 grade. Through precise tool compensation and the repeat positioning accuracy of the machine tool, the dimensional accuracy of the processed parts can be guaranteed.

 

Youdaoplaceholder0 Shape accuracy ‌ : For the shape accuracy of parts, such as roundness and cylindricity, the through-feed machine can also have good control. Generally, the roundness can be controlled within 0.005mm and the cylindricity within 0.01mm.

 

Youdaoplaceholder0 Positional accuracy ‌ : When processing multiple features, the through-feed machine can ensure the positional accuracy among each feature, such as coaxiality, perpendicularity, etc. The coaxiality can generally be controlled within 0.01mm, and the perpendicularity can be controlled within 0.02mm.

 

Youdaoplaceholder0 application scenarios ‌

 

Youdaoplaceholder0 Mechanical manufacturing industry ‌ : widely applied in the processing of various mechanical parts, such as automotive parts, aerospace parts, machine tool parts, etc. For instance, processing parts such as crankshafts and connecting rods for automotive engines.

 

Youdaoplaceholder0 electronic and electrical industry ‌ : It can be used to process precision parts of electronic and electrical products, such as shafts, sleeves and other parts. For instance, processing the shaft parts in the mobile phone camera module.

 

Youdaoplaceholder0 instrument and meter industry ‌ : Processing various precision parts in instruments and meters, such as watch parts, optical instrument parts, etc. For instance, processing parts such as spring shafts and gears in watches.
