A milling machine fly-cutter with adjustable cutting-tool geometric angle and milling machine includes a fly-cutter plate body, a plurality of combination grooves are evenly set in the circumferential direction of the fly-cutter plate body, and adjusting assemblies are mounted in the combination grooves. Wherein, the adjusting assemblies include an adjusting block for rake angle and relief angle, an adjusting block for tool cutting edge angle and minor cutting edge angle, an adjusting block for tool cutting edge inclination angle. A first side of the adjusting block is attached with a cutter handle, and a second side is connected with the adjusting block for rake angle and relief angle by the adjusting block for tool cutting edge angle and minor cutting edge angle. The milling machine fly-cutter realizes adjustment of the geometric angles of cutting tool, and is able to adapt to cutter handles of a variety of different specifications.

A rotary cutting tool has a tool holder and a cutting portion releasably attached to the tool holder. The tool holder includes a mounting portion designed to be attached to a spindle. The rotary cutting tool also has a fluid channel and an energy harvesting arrangement which includes a turbine located in the fluid channel. The fluid channel opens out to a channel inlet opening, for the supply of fluid, located at the mounting portion and a channel outlet opening in fluid communication with the channel inlet opening.

A modular additive manufactured tool assembly includes a perishable tool and a tool holder coupled to the perishable tool. The tool assembly is configured to be coupled to a machine spindle. The tool assembly also includes a spindle connection coupled to the tool holder. The spindle connection is configured to be coupled to a machine spindle. Each of the tool holder and the perishable tool includes a perishable material. Each of the tool holder and the perishable tool is manufactured using an additive manufacturing process.

An assembled chamfer mill comprises a tool holder, an extension shaft, and chamfer bits locked to two ends of the extension shaft. The chamfer bits each have upper blades and lower blades for chamfering the edges of a workpiece simultaneously. The length of a shaft body of the extension shaft may be set in various sizes. Depending on the thickness and shape of the workpiece, the shaft body having an appropriate length is selected, so as to control the distance between the two chamfer bits. Another extension shaft may be provided to connect a further chamber bit for chamfering the edges of the workpiece simultaneously.
