A system for machining and positioning an automobile hub and a production line for intelligent cleaning and precision including upper and lower mounting plates connected vertically. At least three U-shaped blocks are fixed on a top surface of the upper plate. An L-shaped support is mounted between every two blocks including a screw-equipped ball head disposed thereon. The support is driven by a first driving apparatus to move along the upper mounting plate. A slidable chuck is disposed in each block, with a push rod assembly connected to the bottom. The assembly is driven by a second driving apparatus to move along the upper mounting plate with the chuck. Three wedges are circumferentially fixed on a top surface of the lower plate and are driven by a third driving apparatus to move along the lower plate. Inclined surfaces of the wedges are mated with bottoms of the push rod assemblies.

The present teachings include techniques for regulating the temperature of coolant used for a wet saw and the like. That is, a wet saw usually accommodates a coolant tank and/or tray, where coolant is pumped therefrom to the saw blade and/or an interface between the saw blade and a material to be cut (e.g., tile), e.g., to lubricate and cool the saw blade. However, when using a wet saw in colder environments, freezing can be a problem. While submersible “bucket heaters” and the like may be used, these heaters can be cumbersome, faulty, and dangerous. Therefore, the present teachings may include a reservoir with an integrated heating element that is built into the tank/tray itself (e.g., within its base), such that the heating element is physically isolated from the coolant contained therein. Such a heated reservoir may be retrofitted onto an existing saw and/or fabricated with the saw itself.

A turning tool includes a tool body and a turning insert, and an insert seat in which the turning insert is mounted. The insert seat includes a bottom surface and a side surface, the side surface having a first surface and a second surface. The first surface includes a contact surface, wherein the contact surface is in contact with a portion of the side surface of the turning insert. The tool body includes a coolant channel, which extends between a coolant channel inlet and a coolant channel outlet opening into a void between the side surface of the turning insert and the first surface of the side surface of the insert seat.

The invention improves machining methods by using cryogenic cooling techniques in combination with a heat source to simultaneously cool a cutting tool while heating a work piece to make the work piece more pliable while increasing efficiency and/or longevity of the cutting tool.

An indexable parting blade has opposite blade first and second sides, a blade peripheral edge, a central index axis, and at least first, second and third insert pockets located along the blade peripheral edge. The parting blade also has first, second and third coolant channels, each forming a coolant path from a corresponding inlet to a corresponding one of the insert pockets. Each coolant channel includes a rake outlet opening out to a rake side of its corresponding insert pocket and a relief outlet opening out to a relief side of that same insert pocket. The inlet corresponding to a given coolant channel is located further from that coolant channel's insert pocket than at least one of (a) the inlet corresponding to a different coolant channel, and (b) the central index axis.

A minimum quantity lubrication (MQL) system includes a controller, a lubricant module coupled to a tool spindle of a machining apparatus, and a pneumatic module coupled to the spindle. The lubricant module is configured to supply lubricant at pressure to the tool, as controlled by the controller. Likewise, the pneumatic module is configured to supply pressurized air to the tool, as controlled by the controller. The controller is configured to direct the lubricant module to supply lubricant prior to the controller receiving a START signal from a machine tool controller. Optionally, the lubricant pressure level is predetermined based on known characteristics of the tool that is coupled to the spindle. Optionally, the START signal is anticipated by referring to a signature/profile of the operational steps of a machining process where a timeline or time table of lubrication request intervals are identified.
