This is one example of a regrinding case for a 12mm end mill that we handled. The corner of this end mill, with a 30-degree twist, has been made into a "pin angle."

• End Mills

This is one example of a regrinding case for a corner R end mill that we handled. The tip diameter is 12mm, and the corner dimension is R1.

• End Mills

This is one example of a regrinding case for a carbide drill that we handled. It has been regrinded with X-shining, a tip angle of 140 degrees, and honing.

• drill

This is one example of a regrinding case for an unequal lead carbide end mill that we handled. We cut the tip without changing the diameter and re-sharpened the bottom cutting edge.

• End Mills

This is one example of a regrinding case for a carbide ball end mill with an R10 radius and a shank diameter of Φ20 that we handled.

• End Mills

This is one example of a regrinding case for a replaceable head carbide end mill that we handled. It is a three-flute end mill with a tip diameter of 20mm, and only the bottom cutting edge has been regrinded.

We would like to introduce a case of regrinding a cermet tool processed by our company. Most of the regrinding we have done has been for carbide and high-speed steel, but recently, we received an inquiry from a customer asking if regrinding cermet tools is possible. At our company, we can also propose ways to extend the tool life of cermet tools through regrinding. If you have any used tools that are just sitting around, please feel free to contact us. [Overview] ■ Regrinding of cermet tools - The tools targeted are those used for bottom edge finishing. - Proposals for extending tool life through regrinding are possible. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case of regrinding a center chamfer drill that we handled. As the name suggests, this is a drill made of carbide with a diameter of φ4.8mm, designed for center chamfering. It is possible to modify the chamfer angle to match the customer's drawing specifications and to reuse the tool. This is an example of processing without coating, but of course, coatings tailored to the customer's requirements are also available.

We would like to introduce a case of regrinding related to the ball end mills processed by our company. In the case of regrinding the R1.5 ball end mill, we performed regrinding on the tip section due to a decline in machining accuracy. As in this case, regrinding allows for the reuse of existing tools, enabling cost reduction. 【Overview】 ■Regrinding of R1.5 ball end mill ・Regrinding of the tip section ・Cost reduction is possible through the reuse of existing tools *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case of regrinding a strong twist radius end mill designed for mold processing that we handled. We received an inquiry from a mold manufacturer regarding a regrinding case we worked on, which involved a significant number of regrinding areas: 1. Cut 2. Bottom blade 3. Corner R0.2. After grinding, we applied a Cr-based multilayer (equivalent to OSG standard WDI) coating. A radius end mill is characterized by having rounded corners on the bottom blade, and using this tool allows for machining with a relatively smooth shape due to the rounded edges of the blade.

In Miyamoto Manufacturing's regrinding business, the unit prices of materials such as carbide and high-speed steel are high, and we propose the reuse and high value-added of expensive tools as tools. These tools made from special materials are mined overseas and processed and provided by various tool manufacturers that import them. As a result, the rising prices of raw materials such as rare metals have led to successive price increases by tool manufacturers. On the other hand, many companies consider tools to be disposable, leading to situations where they are discarded or left on shelves. Our company believes that we can revive such tools and utilize them in our customers' production, which is why we engage in the regrinding business. 【Features】 ■ 70% reduction compared to new products ■ High-quality and cutting performance regrinding that only a manufacturer can provide ■ Just-in-time production proposals for tool regrinding *For more details, please refer to the PDF materials or feel free to contact us.
