Announcement of New Equipment Installation (Ultra-Precision CNC Surface Grinding Machine)

An explanation of machine tools for machining, such as cylindrical grinding, wire electrical discharge machining, and surface grinding machines, presented in an easy-to-understand manner for newcomers and beginners! Materials are available!

This document introduces basic knowledge about machining as an introduction to machine processing. It provides detailed information about machine tools such as the "lathe," which rotates materials and uses cutting tools to shape them, and the "machining center," which performs milling operations with NC control. Maruwa Machinery Co., Ltd., which conducts ultra-precision machining at the micron level, as well as the production of various jigs and precision gauges with over 70 different processing machines, has explained this in an easy-to-understand manner for newcomers and beginners. It is a useful reference, so please take a moment to read it.

We have released a new video on our company’s YouTube channel. The theme of this video is "The World of Amino Acid-Based Shampoos." Amino acid-based shampoos have become popular in recent years, but the lather, feel, and finish can vary greatly depending on the cleansing ingredients used. In this video, we clearly explain the changes in user experience based on the differences in cleansing ingredients by comparing two types of amino acid-based shampoos. We hope you can use this as a hint for developing original shampoos and differentiation.

[To the owners of parking lots and parking lot construction companies] "I’m worried about not colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures using various sensors and alerts the surroundings with LED lights and buzzers. The device consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *Please note that a separate control panel is required to include the controller and switching power supply (24V) when using the exit warning system. *We kindly ask that customers arrange for the switching power supply (24V), LED rotating light, control panel, circuit breakers, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. We hope this will contribute to safer vehicle passage for everyone. ◎ For more details, please contact us or download the catalog.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for metal crack repair without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.

Hotron, which manufactures and sells sensors, provides bed exit sensors for hospitals, nursing, and care facilities. Hotron offers easy-to-understand video guidance on how to use the bed exit sensors wirelessly and how to set up device connections! ▼ Video Manual (YouTube) https://www.youtube.com/playlist?list=PLNVA4mTrZDqtJa6MfFRZQxwtfCSnAfxVy 【Bed Exit Sensors】 ○ Non-contact infrared sensor, simply place it - Pole-kun HB-H1 ○ Mat sensor, foldable thin mat - Mat-kun HB-UST ○ Body movement call - Ugo-kun HB-TV3 ○ Body movement call for wheelchairs - Ayumi-chan HB-WTV3 【Options】 ○ Nurse call linked wireless set - Wireless set (transmitter/receiver) HB-RS/HB-RJ ◎ For more information about the products, please contact us or download the catalog.
