The machine tool (1) machining a workpiece (W) while moving a tool and the workpiece (W) relative to each other includes a cover (2) separating from outside a machining area for machining the workpiece (W) therein, and temperature adjusting means (30) used in machining of the workpiece (W) to adjust an ambient temperature of the machining area.

The present disclosure is directed toward a tooling assembly for a machine having an automatic tool changing system. The tooling assembly includes a holder, a tool body, and an internal passage defined within and extending through the holder and the tool body. The holder includes a machine interface configured to engage with a spindle of the machine. The internal passage is operable to have a coolant fluid flow within, and has a stem channel and a curved channel extending from the stem channel.

A milling machine processing system with an intelligently follow-up cutting fluid nozzle and a working method thereof including a workpiece stage, a milling machine box arranged above the workpiece stage, a milling cutter mechanism mounted on the milling machine box for processing workpieces on the workpiece stage, a rotating mechanism mounted on an end surface of the milling machine box located at a side of a milling cutter, the rotating mechanism is connected with a two-axis linkage mechanism and drives the two-axis linkage mechanism to rotate about a center line where the milling cutter is located, the two-axis linkage system is connected with a nozzle through an angle adjusting mechanism and is used for adjusting a position and an angle of the nozzle, and the milling machine processing system has an infrared temperature detection module for collecting the temperature of a processing region.

In one aspect, rotary cutting tools are described herein comprising sets of coolant channels having exit aperture in the flutes of the tools for efficient coolant delivery to multiple cutting surfaces. Briefly, a rotary cutting tool comprises a shank portion, and a cutting portion extending from the shank portion along a longitudinal axis, the cutting portion comprising flutes helically extending along the longitudinal axis and internal coolant channels comprising exit apertures in the flutes. A projection of an exit aperture of a first set of internal coolant channels intersects a rake face extending below a corner edge of the rotary cutting tool, and a projection of an exit aperture of a second set of internal coolant channels intersects a rake face below a radial cutting edge of the rotary cutting tool.

A method of priming a minimum quantity lubrication (MQL) tool includes determining a category of the tool, supplying a short-prime MQL dosage if the tool is a first category or if both a second category and lubricated within a first predetermined timeframe, and supplying a long-prime MQL dosage if the tool is the second category and has not been lubricated within the predetermined timeframe. The category is based on internal passage complexity of the tool.

The invention provides a toolholder matched with the internal jet cooling spindle for cryogenic coolant. The toolholder is mainly composed of a hollow toolholder body, a high-performance thermal insulation structure and a bidirectional sealing structure. They can guide the cryogenic coolant from the spindle to the internal cooling channel of tool and realize the cryogenic thermal insulation and dynamic sealing. The high-performance thermal insulation structure inside the toolholder employs the material with a low thermal conductivity and a low linear expansion coefficient to restrain the low temperature impact of cryogenic coolant on the toolholder and spindle, to ensure the dimensional accuracy and assembly accuracy of the toolholder. The bidirectional sealing structure in the toolholder uses the ultra-low temperature resistant seal rings to prevent the cryogenic coolant from leaking towards the spindle and the tool, to ensure the stability of the coolant transport.

This disclosure relates to a cutting tool, having a main body, a cutting head, which is joined to the free end of the main body and is formed, by primary shaping, as a sintered piece provided with at least one cutting edge, and a cooling lubricant feed, which is led through the main body axially and which has a cooling lubricant distributor inserted into the cutting head for redirecting cooling lubricant into the region of the at least one cutting edge. According to this disclosure, a plurality of protruding spacers for keeping a gap clear with respect to the cooling lubricant distributor and/or the main body are sintered on a supporting surface of the cutting head as primary shaped elements.

The whirling device comprises a retaining ring extending around a ring axis and a central opening and having at least one receiving area for a machining element for machining rod-shaped material in the area of the central opening. A coolant supply comprises a supply sleeve which is arranged on the retaining ring via a rotary bearing and comprises a coolant connection and a supply area adjoining a connection area of the retaining ring. Starting from at least one inlet opening in the connection area of the retaining ring, at least one passage leads through the retaining ring to at least one outlet opening which faces the central opening of the retaining ring and is designed for a machining element in a receiving area. No space is required for the coolant supply between the retaining ring and an assigned lathe.
