Iwaki, Japan – May, 2026 – Tungaloy Corporation (President: Satoshi Kinoshita, Head Office: Iwaki City, Fukushima Prefecture) announces the expansion of its SpinJet series, featuring a new generation model equipped with a cartridge-type design and app-based spindle speed monitoring, enabling cost reduction, simplified maintenance, and enhanced machining efficiency across various machine interfaces.
Challenges and Trends
In fields such as die and mold, automotive, and heavy industry, higher precision and efficiency in machining are increasingly required. However, in general-purpose machines — particularly those used for small-diameter machining — productivity has been declining due to limitations in spindle speed and the aging of equipment.
Conventional SpinJet units require a separately sold dedicated monitor to measure rotational speed, which increases both implementation costs and management workload. Moreover, because the spindle and interface are integrated into a single structure, a spindle failure necessitates the repurchase of the entire unit, resulting in a significant cost burden.
On the shop floor, there is a strong demand for new solutions that can achieve high-speed, high-precision machining while making full use of existing equipment.
Product Overview
SpinJet is a speed-increasing spindle that enables high-speed rotation of small-diameter tools and high-efficiency machining when mounted on existing machine tools. Driven by a dedicated turbine powered by coolant pressure, it offers excellent energy efficiency. In addition, the cooling effect of the coolant jet contributes to longer tool life and stable machining.
Benefits and Features
Feature 1: Rotation Speed Monitoring via App
– A dedicated app, available for free download, enables real-time monitoring of spindle rotation speed.
– Eliminates the need for a dedicated monitor, significantly reducing installation costs.
– Easy operation via smartphone or tablet enhances on-site usability.
Feature 2: Cartridge-Type Spindle Drive Unit
– Adopts a cartridge structure that standardizes the spindle drive unit.
– Allows sharing between different interfaces, improving equipment versatility.
– In case of failure, only the cartridge needs to be replaced, reducing maintenance costs.
Feature 3: Compatibility with Various Interfaces
– Supports a wide range of interfaces including ER32, BT40, HSK-A63, C6, ST20, and CAT40.
– Can be mounted directly onto existing equipment, minimizing additional investment.
