It's not just about inner diameter and grooving processes. Outer diameter processing results can also change depending on how coolant is applied. With PSI Turn, anyone can apply coolant precisely to the cutting edge. This is effective in improving chip removal issues and reducing the frequency of tool changes. PSI Turn was developed to safely advance the machining process and increase productivity through internal lubrication processing. It can accurately supply coolant to the cutting edge from two directions: the relief face and the rake face, making chip removal easier and helping to suppress wear. The head is designed to be as compact as possible, reducing the risk of chips wrapping around it.

Waring processing is a method that allows for the efficient machining of long screws, high lead screws, worm gears, and more using a automatic lathe. It employs a special disk equipped with numerous inserts arranged in a dedicated holder that allows for angle adjustments. The disk is offset relative to the workpiece, and both the workpiece and the ring are rotated in the same direction during processing. This method minimizes burr formation and can efficiently process large amounts of material, making it widely used for machining titanium and stainless steel bone screws. At Yamada Machine Tool, we can provide total coordination for the introduction of PCM-made tool holders, disks, and inserts used in this special processing.

The screw rolling head typically involves three rolls and enters the material from the end face in the axial direction to roll the screw. It uses a step rolling method that rolls one thread at a time from the tip, resulting in less load on the machine and the workpiece. Regardless of the rotation speed, it advances by the pitch per rotation. The rolls can advance in the axial direction regardless of their length, allowing for flexible setting of screw length. There are F-type heads used for rotating workpieces (such as lathes) and G-type heads that can rotate the head (used for machining centers, etc.). ■ Features of the ARC screw rolling head - It can be mounted on CNC lathes, allowing the cutting process and rolling process to be consolidated into a single CNC lathe. ■ Advantages of rolled screws 1. Improved screw strength Strength is enhanced due to work hardening from plastic deformation and densification of the structure. 2. Improved surface roughness The surface is varnished and finished with a glossy appearance. 3. Reduced processing time With high peripheral speeds and pitch feeding, the processing time is relatively short for finishing. 4. Reduced setup time The lifespan of the rolls is generally longer compared to cutting tools, reducing the frequency of tool changes. 5. Prevention of burrs, cracks, and rust The structure becomes stronger due to plastic deformation, significantly reducing the defect rate.

We are now in an era where milling holders are selected and purchased according to the machining process, just like tools and equipment. In Japan, when purchasing automatic lathes, it is common to choose genuine milling holders. On the other hand, in Europe and the United States, there are many cases where non-genuine products are selected. Recently, there has been an increase in the processing of difficult-to-cut materials and complex machining. To address these needs, attention is also being drawn to automatic lathe milling holders. Choosing milling holders that match the machining process, just like selecting equipment and cutting tools, may prove to be a reliable asset. There are high-torque holders, speed-up holders, and hob processing units that cannot be covered by genuine products, and if you are not aware of them, you won't even be able to choose. Please consider them as options when updating equipment or when you hit a wall in your machining processes.

The slitting tool processes keyways, polygonal holes, splines, and more using cutting machines such as lathes and machining centers. The motorized slitting unit BENZ LinA4.0 is designed to perform this slitting operation more efficiently on a multi-tasking lathe. Compared to slitting operations that slide the turret, processing is completed at approximately 3 to 6 times the speed, making it efficient for mass production parts as well as for processing multi-tooth shapes such as splines and serrations. The BENZ LinA4.0 is a unit that converts the rotation of the milling axis of a multi-tasking lathe into a four-stroke linear motion, transforming the rotation from the motor into the four tool paths necessary for slitting operations through its internal mechanical mechanism.

The QUICK lathe marking tool is a new concept tool that performs marking inside CNC lathes. Traditionally, marking is often done manually in the next process after lathe machining, which has the following disadvantages: - Yield loss occurs since it is done in the next process. - Mistakes can happen due to manual marking. - There is a risk of injury to the operator with manual stamping. By introducing this lathe marking tool into your lathes, it is possible to improve the above disadvantages. *For more details, please refer to the PDF document or feel free to contact us.*

We receive inquiries every day from customers looking for knurling tools. A common question is whether cutting or rolling is better. We primarily recommend cutting, as it provides a nice finish and is relatively easy to set up. However, there are workpieces where cutting knurling tools cannot be used. In such cases, we recommend rolling knurling tools. Rolling knurling tools can handle knurling on the intermediate sections of workpieces and processing at step edges, which is difficult with cutting knurling tools. *For more details, please refer to the PDF document or feel free to contact us.*

Features of the QUICK Knurling Tool The QUICK knurling tool is a cutting-type knurling tool developed through years of experience and research by the QUICK brand, fundamentally changing the traditional knurling process that uses pressing and rolling. It is a unique knurling tool that is now distributed to users around the world, demonstrating its effectiveness. In Japan, it has a history of over 30 years since its release and continues to accumulate various know-how. The QUICK knurling tool series can be attached to lathes for use. Since it is used for cutting, which is the purpose of a lathe, the load is smaller compared to pressing and rolling, minimizing stress on materials and machines. It can also process materials that are impossible to roll. Another feature is that the high rotation speed results in shorter processing times. The sharp finish of the peaks leads to a cleaner result compared to plastic deformation. This not only reduces processing and setup times but also dramatically improves quality. *For more details, please refer to the PDF document or feel free to contact us.*

Thread rolling is the process of deforming a round bar material by sandwiching it between multiple rolls shaped like threads and pressing it while rotating, thereby creating the shape of the thread. Thread rolling is performed as a cold forming process that does not produce chips. The material's structure is deformed without being cut. By plastically deforming the material, advantages such as increased strength and rust prevention effects, which are not present in cutting, can also be obtained. Thread rolling is widely used for various types of threads, including triangular, acme, trapezoidal (TR), buttress, tapered, and special-shaped threads. Until now, thread rolling required a dedicated machine for a standalone process, but by incorporating the tools proposed by YAMADA into NC machines or automatic lathes, significant reductions in processing time and advancements in automation can be achieved. 【Contents】 - What is thread rolling? - Can any material be processed? - What shapes can be made through rolling?
