The chip removal device can also include a main fluid channel with an opening to receive pressurized fluid from the machine tool. The chip removal device can further include a first fluid delivery channel and a second fluid delivery channel to direct fluid in different directions. Each fluid delivery channel can be in fluid communication with the main fluid channel. In addition, the chip removal device can include one or more valves associated with the first and second fluid delivery channels to selectively allow fluid passage from the main fluid channel to the fluid delivery channels. The one or more valves can be actuated by varying fluid pressure and/or rotational speed. ## Claims ### Claim 1 A machine tool chip removal device, comprising: a spindle coupling interface to couple with a rotatable spindle of a machine tool to facilitate rotation of the machine tool chip removal device about an axis at a rotational speed; a main fluid channel with an opening to receive pressurized fluid from the machine tool; a first fluid delivery channel and a second fluid delivery channel to direct fluid in different directions, each fluid delivery channel in fluid communication with the main fluid channel; and one or more valves associated with the first and second fluid delivery channels, respectively, wherein the one or more valves are actuatable by varying the rotational speed of the machine tool chip removal device to selectively allow fluid passage from the main fluid channel to the first and second fluid delivery channels, wherein the one or more valves each comprise an orifice, a movable plug configured to block the orifice, and a spring acting on the plug to bias the plug relative to the orifice. ### Claim 2 (depends on 1) The machine tool chip removal device of claim 1, wherein the one or more valves are normally open. ### Claim 3 (depends on 1) The machine tool chip removal device of claim 1, wherein the spring acts on the plug to bias the plug away from the orifice. ### Claim 4 (depends on 1) The machine tool chip removal device of claim 1, wherein movement of the plug is in a direction parallel to the axis such that the one or more valves are actuated only by fluid pressure acting on the plug, respectively. ### Claim 5 (depends on 1) The machine tool chip removal device of claim 1, wherein an outlet of the first fluid delivery channel is configured to direct fluid in a direction parallel to the axis. ### Claim 6 (depends on 1) The machine tool chip removal device of claim 1, wherein the one or more valves are normally closed. ### Claim 7 (depends on 1) The machine tool chip removal device of claim 1, wherein the spring acts on the plug to bias the plug toward the orifice. ### Claim 8 (depends on 1) The machine tool chip removal device of claim 1, wherein movement of the plug is in a direction non-parallel to the axis such that the valve is actuated at least in part by centrifugal force acting on the plug. ### Claim 9 (depends on 1) The machine tool chip removal device of claim 1, wherein an outlet of the first fluid delivery channel is configured to direct fluid in a direction non-parallel to the axis. ### Claim 10 (depends on 1) The machine tool chip removal device of claim 1, wherein a preload of the spring is adjustable. ### Claim 11 (depends on 1) The machine tool chip removal device of claim 1, wherein the spring interfaces with a spring seat that is movable relative to the orifice to adjust preload. ### Claim 12 (depends on 1) The machine tool chip removal device of claim 1, wherein the spring seat comprises an opening to facilitate passage of fluid therethrough. ### Claim 13 (depends on 1) The machine tool chip removal device of claim 1, wherein the one or more valves comprises a first valve and a second valve. ### Claim 14 (depends on 13) The machine tool chip removal device of claim 13, wherein the springs of the first and second valves, respectively, have different spring rates. ### Claim 15 (depends on 13) The machine tool chip removal device of claim 13, wherein the springs of the first and second valves, respectively, have different preloads. ### Claim 16 A machine tool chip removal system, comprising: a machine tool; and a machine tool chip removal device operably coupled to the machine tool, the machine tool chip removal device having a coupling interface to couple with a rotatable spindle of the machine tool to facilitate rotation of the machine tool chip removal device about an axis at a rotational speed, a main fluid channel with an opening to receive pressurized fluid from the machine tool, a first fluid delivery channel and a second fluid delivery channel to direct fluid in different directions, each fluid delivery channel in fluid communication with the main fluid channel, and one or more valves associated with the first and second fluid delivery channels, respectively, wherein the one or more valves are actuatable by varying the rotational speed of the machine tool chip removal device to selectively allow fluid passage from the main fluid channel to the fluid delivery channels, wherein the one or more valves each comprise an orifice, a movable plug configured to block the orifice, and a spring acting on the plug to bias the plug relative to the orifice. ### Claim 17 (depends on 16) The system of claim 16, wherein the machine tool comprises a mill, a lathe, or a combination thereof. ### Claim 18 (depends on 16) The system of claim 16, wherein the pressurized fluid comprises at least one of a gas and a liquid.
