In the past few days, I believe that everyone has learned from many channels what a melt blown die is, and also know that the key to processing a melt blown die is the processing of micropores. Its aperture is from Ф0.1-0.3mm, and the ratio of depth to diameter is If it exceeds 10, it will be difficult to process. However, have you ever thought about how such a small hole is made?
Today we will introduce to you a kind of equipment tool grinder for producing drill bits. In the development of global tool grinding machines, Japan's Makino Seiki has always played a leading role. In 1982, it successfully developed the world's first 10-axis control CNC tool grinding machine. Makino Seiki's high-precision CNC small-diameter tool grinder SS7 can grind drills as small as Ф0.05mm.
Let's learn about the process of grinding and producing micro-drills using a Japanese Makino Seiki tool grinder through a video.
High Precision CNC Small Diameter Tool Grinder SS7
SS7 is a special grinding machine for the production of small-diameter cutting tools specially made by Makino Seiki. Realize the high-precision machining of each tool, control the tool size change within the minimum range during continuous machining, greatly reduce the preparation time, improve production performance, etc., and concentrate all the development technologies of Makino Seiki's small-diameter tool processing.

1. Machine tool structure
Linear axes (X, Y, Z) are equipped with grating scales as standard, and rotary axes use DD direct drive motors to achieve high-precision positioning and indexing accuracy.
2. Measures to prevent thermal deformation
The left and right symmetrical structure design of the machine body can minimize the impact caused by thermal changes. Realization of stability during long-term continuous machining and high-precision production of tools. Equipped with the automatic cooling fluid circulation function of the bed after starting up, the cooling fluid will circulate even when there is no grinding, ensuring the temperature balance of the machine body and making the machining accuracy more stable.

4. Work spindle
The rotation of the working spindle adopts a direct drive motor, which eliminates the influence of the clearance and ensures the precise indexing angle. Standardly equipped with a workpiece support frame that can greatly improve the runout accuracy of workpiece clamping.

5. Automatic device
The built-in loader, which has been produced unmanned for a long time, has increased the number of loaded storage items compared with the previous machine, and improved the convenience function in use.
