Barrel polishing machine [Tank tilting can be operated by button]

Tank tilting is possible with button operation! The highly functional Yamashina tiltable barrel polishing machine.

The "Automatic Tilting Barrel Polisher" is a barrel polishing machine that allows for tank tilting to be operated by a button. Barrel polishing involves placing workpieces (products), media (abrasive stones), compounds (abrasives), and water into a barrel tank, applying a constant rotational motion to stir them, and allowing mutual friction to remove burrs and edges, eliminate scale, and achieve a glossy finish. Once the working conditions are set, a consistent and uniform finish can always be obtained without variation, making it suitable for finishing mass-produced items. [Features] ■ Tank tilting can be operated by a button For more details, please contact us or download the catalog.

Barrel polishing machine [Capable of processing large and heavy items]

It is possible to process high-weight workpieces! The Yamashina tiltable barrel polishing machine enables efficient polishing.

The "Tank Direct Drive Barrel Polisher" has an extremely simple structure with few maintenance points. Barrel polishing involves placing workpieces (products), media (abrasive stones), compounds (abrasives), and water into a barrel tank and applying a constant rotational motion to stir them, allowing for mutual friction. This process can remove burrs and edges, eliminate scale, and achieve a glossy finish. Once the working conditions are set, it consistently produces uniform results without variation, making it suitable for finishing mass-produced items. 【Features】 ■ Capable of processing high-density workpieces ■ Extremely simple structure with few maintenance points ■ Speed control via inverter ■ Tank tilting can be operated with a button For more details, please refer to the catalog or feel free to contact us.

Oil flow sensor automates oil discharge confirmation [labor-saving].

It is a sensor that connects to the piping line to check whether oil is being regularly sent from the oil pump to the lubrication points!

■Preventive Maintenance and Improved Operating Rate Early detection of poor lubrication in production equipment is possible. ■Remote Monitoring Confirmation of lubrication in hazardous areas that are not accessible on a daily basis can be performed. ■Centralized Management, Automation, and Labor Reduction (Cost Reduction) The confirmation of oil discharge in daily operations can be changed from visual checks to automation. ■Hazard Prevention Lubrication confirmation can be performed from outside even while the machine is in operation. 《Point 1》 Robust construction that can be used in harsh environments such as high temperature and high vibration, like the cylinders of marine diesel engines. 《Point 2》 Complete separation design of fluid pathways and electronic components ensures excellent pressure and heat resistance, eliminating concerns about leakage. 《Point 3》 No worries about magnetization or electrical contact, making it suitable for confirming oil discharge.

Electromagnetic Timing Lubricator (EDL) System

By receiving control signals and electrically driving the oil supply plunger at high speed, pinpoint lubrication can be achieved with high speed and high efficiency!

■Low Cost (as a system) Unlike other electronic lubrication systems, there is no need for a hydraulic pump system. It is supplied from a head tank like conventional systems, and there are no system license fees required. ■Long Lifespan There are no mechanical shock impacts, and it does not use delicate solenoid valves, resulting in a long lifespan (over 100 million cycles). ■Energy Saving & Space Saving The control circuits are built into each lubricator, and they output lubrication timing and fault status externally. Additionally, since power is consumed only for a brief moment during lubrication, the energy usage efficiency is extremely high (approximately 20W at 180 cpm). The absence of a hydraulic pump unit contributes to energy and space savings. ■High Speed It can operate at a maximum of 180 times per minute (net discharge time of 2-3 msec).
