An internal oil supply MQL device sprays oil mist onto the cutting edge through the piping of the machining center.
【Features】 Mist spraying capability from a 1mm diameter nozzle: Mist is sprayed from the main body nozzle at an air pressure that is almost equal to the supplied air pressure. When 0.5MPa of air is supplied, the air pressure at the nozzle is almost 0.5MPa with no pressure drop. This pressure allows for powerful mist spraying even from a 1mm diameter nozzle. (Test conducted using test piping prepared by our company) Automatic oil quantity adjustment: The oil quantity automatically increases or decreases in response to changes in nozzle diameter. When the nozzle diameter increases, the air volume increases, and the oil quantity also automatically increases. Conversely, when the nozzle diameter decreases, the oil quantity similarly decreases. It consistently sprays mist with almost constant density in response to changes in nozzle diameter. In a system that supplies oil via a pump, adjustments to the number of piston movements must be made based on the M signal, which requires effort in creating and modifying the program. Maintenance-free: Instead of using a piston pump, liquid is pushed out by the difference in air pressure from a special airline mechanism, sent to the nozzle section, and atomized with high-pressure air. Since there are no piston components or filters, it can be considered almost maintenance-free.

basic information
This machine is the latest model developed for through spindles of machining centers and through turrets of CNC lathes. Design Intent: This machine was developed with the intention of injecting micro mist from an oil hold drill. To achieve this, it is designed to spray mist at a high pressure nearly equal to the supply pressure. Additionally, it does not use pumps or cylinders that could cause failures or wear. It also does not use filters that require regular maintenance. Furthermore, it is designed to automatically adjust the oil volume in response to changes in nozzle diameter.

Applications/Examples of results
Applicable Usage: ◎ Use with through spindle on machining centers Oil hole drills, oil hole taps, collet through, etc. ◎ Use with through turret on CNC lathes Oil hole through holders, oil hole drills, turret-mounted nozzles, etc. (*Rotary joints and other piping components must be compatible with mist injection.) Main Specifications: Dimensions/Weight/Liquid Capacity: 142x145x301mm, approximately 6.0kg, approximately 1,000cc Supply Air Pressure: 0.4 to 0.6 MPa Oil Volume Setting: The initial setting is done using the oil volume setting knob. (After that, it automatically adjusts according to changes in nozzle diameter. There is no need for any troubleshooting related to setting changes for piston counts via M signals.)

Company information
Our company was established as the domestic sales company for imported unique and excellent machine tools and cutting fluids observed at factories in Europe and the United States by Seiki Export Group Co., Ltd. With the arrival of the ecological era, we focused on ultra-low lubrication oil mist sprays that do not use cutting fluids, and completed the Semi-Dry Cut System No. 1 in the summer of 1998. Since then, we have made improvements and expanded our product range, including the DC-II with a Lockline nozzle and the DC-S4 with a through-spindle design, creating a system to meet all customer requests and working to promote and expand this new method.
