Title:
適応型Ｒ７４４最小量冷却潤滑システム
Document Type and Number:
Japanese Patent JP7258888
Kind Code:
B2
Abstract:
This application presents a method and apparatus for cooling a through-ported cutting tool with a source of liquid CO2 with a compressed air line with a compressed air inlet and multiple CO2 injection capillary segments; the capillary segments interconnect to the same source of liquid CO2 and can have high pressure valves and throttles; the throttles have different sizes; a first capillary ends near the cutting tool; the second capillary ends near the compressed air inlet. Using a particular sequence of opening or closing the valves to the liquid CO2 to the capillaries, mixing with the compressed air provides and recycling the residual CO2, this invention provides for uniform and controlled cooling of the cutting tool within a certain temperature range.
