A milling tool having a shank portion and a head portion extending from the shank portion. A head internal surface of the head portion is formed with a peripherally extending head coolant obstruction arrangement comprising a head ridge which extends in a rearward direction more than an adjacent head portion of the head internal surface located in a radially-inward direction more than the head ridge.

This invention relates to cutting tools used to machine materials to produce new surfaces and chips of removed material. Embodiments of this invention allow round rotating cutting inserts to be used in a more economical way, with improved accuracy, with improved sealing, and with greater ease of use. The rotary support device and cutting inserts may be used in either radial or tangential mounting types of cutters. It also provides a built-in, fully sealed means of fine adjustment of the cutting insert that is useful in some applications.

An intelligent switching system for switching internal cooling and external cooling and a method are provided. The system includes a vision system, a cooling system and a control system. The vision system monitors a real-time milling state of a cutter, collects a real-time milling depth image that the cutter mills a workpiece, and transmits the collected real-time milling depth image to the control system. The control system includes a lubrication mode control center, and a motor control center. The lubrication mode control center receives the real-time image transmitted by the image collection control center; analyzes and processes the real-time image to obtain real-time milling depth data of the cutter. The motor control center receives a signal sent by the lubrication mode control center; analyzes and processes the signal, and transmits a control instruction to the cooling system. The cooling system executes a switching command issued by the control system.

The present invention belongs to the technical field of milling machines, and mainly relates to a novel cutter holder and base system for a milling machine. The cutter holder and base system according to the present invention aims to solve the problems in the prior art that a cutter holder structure is unreasonable, the cutting force of a cutter cannot be well dispersed in the cutter holder and a base, so that the service lives of the cutter holder and the base are shortened. The base is provided with a hole-shaped inner area and two curved surface areas, where the two curved surface areas are disposed in a circumferential area of the hole-shaped inner area, the curved surface areas are arranged at an angle, and each curved surface area includes two curved surfaces. The cutter holder improves its own usage performance while a lighter weight is achieved.

A slot milling disc has an outer peripheral surface provided with a number of cutting edges, an attachment arrangement allowing rotary preventing attachment of the slot milling disc to a rotatable mounting shaft and at least one flushing fluid channel having a confined cross-section and extending within the milling disc from an inlet opening located in a central part of the disc and configured to be connected to a source of flushing fluid to at least one outlet opening in the peripheral surface of the disc. The flushing fluid channel has an inner channel portion extending from the inlet opening towards the peripheral surface and ending before reaching the peripheral surface and at least one outer channel portion extending from the inner channel portion while changing direction of the flushing fluid channel and extending to the at least one outlet opening.

This invention relates to simple, compact rotary seals that contract to maintain a seal as the sealing elements may wear over time. Embodiments of this invention allow simple elastic rings, such as an O-ring, to be used as the sealing element.

A device for mechanically removing material from a workpiece or bulk feedstock, thereby creating chips of removed material while producing a new surface on the workpiece or bulk feedstock. The device comprises a body and at least one round cutting insert that is tangentially mounted on the body. Location and orientation of the insert is characterized by a reference plane offset and an insert axis angle. The insert has an outwardly-facing rake surface on which chips are formed. A planar flank surface is oriented relative to a cutting motion so as to provide clearance between the cutting insert and the surface created by removal of a layer that is converted into chips. A circular cutting edge lies at the intersection of the flank and rake surfaces.
