Patent number: 10759011Abstract: A method for installing an adjustable camshaft may include inserting an adjustable camshaft in an installation device. The camshaft may include an outer shaft surrounding an inner shaft. The installation device may enable alignment of at least one cam rotatably mounted on the outer shaft. The method may include aligning the at least one cam by pushing an alignment pin through a radial passthrough opening in the at least one cam and through a drillhole in the inner shaft congruent therewith. The method may include non-rotatably connecting the at least one cam to the inner shaft by pushing a connecting pin into the passthrough opening and the drillhole in a direction opposite a direction the alignment pin was pushed. Non-rotatably connecting the at least one cam to the inner shaft may include detachably coupling the connecting pin and the alignment pin in a positive locking manner.Type: GrantFiled: March 13, 2018Date of Patent: September 1, 2020Assignee: Mahle International GmbHInventors: Thomas Flender, Stefan Steichele

Patent number: 10759012Abstract: A motor controller comprises: a motor driver arranged at a housing attached to a machine support; fan motors and arranged in or outside the housing; and a control unit. The motor driver drives motors. The fan motors blow cooling air for cooling the interior of the housing. The CPU includes a machining mode selection unit allowing selection of at least either a first machining mode of machining a machining target finely or a second machining mode of machining the machining target more roughly than in the first machining mode. If the first machining mode is selected, the machining mode selection unit exerts control to change the rotation numbers of the fan motors and so as to reduce vibration to be transmitted from the housing to the support column.Type: GrantFiled: April 24, 2019Date of Patent: September 1, 2020Assignee: FANUC CORPORATIONInventors: Genzo Naito, Yoshinori Hoshino, Kazuhiro Yamamoto

Patent number: 10759013Abstract: A dust containment apparatus includes a tubular snorkel and dust bellows surrounding the implement of an air too, and a retention assembly housed within the snorkel that frictionally engages the implement to resist movement of the snorkel and bellows with respect to the implement. The retention assembly includes a set of friction members surrounding the radial periphery of the implement, and at least one resilient band that biases the friction members radially inward into pressing engagement with the implement. Preferably, the snorkel and friction members are constructed of non-magnetic material, and the friction members include permanent magnets that are magnetically attracted to the implement to augment the radially inward biasing of the resilient band.Type: GrantFiled: July 20, 2018Date of Patent: September 1, 2020Assignee: G.A.W. Inc.Inventors: Robert Arthur, Nathaniel P. Wenzel, Kenan Wollborg, Nicholas J. Russell

Patent number: 10759014Abstract: This application presents a method and apparatus for cooling a through-ported cutting tool with a source of liquid CO2 with a compressed air line with a compressed air inlet and multiple CO2 injection capillary segments; the capillary segments interconnect to the same source of liquid CO2 and can have high pressure valves and throttles; the throttles have different sizes; a first capillary ends near the cutting tool; the second capillary ends near the compressed air inlet. Using a particular sequence of opening or closing the valves to the liquid CO2 to the capillaries, mixing with the compressed air provides and recycling the residual CO2, this invention provides for uniform and controlled cooling of the cutting tool within a certain temperature range.Type: GrantFiled: December 11, 2018Date of Patent: September 1, 2020Assignee: HITACHI HIGH TECH CORPORATIONInventors: David P. Jackson, Mackenzie A. Jackson, John J. Lee

Patent number: 10759015Abstract: A method and a system for machining a work piece by a machining tool are provided. The method includes relatively moving the machining tool against the work piece to apply machining feeds therebetween. The contact points at the work piece are arranged on the area of the work piece to be machined, and the contact points at the machining tool form a curve on the machining tool surface. The system includes a manipulator, a machining tool and a controller being adapted for controlling the manipulator to operate the machining tool according to the method as above. With this solution, the system can generate wave paths of a machining tool, so as to extend the life of the tool and ensure the processing quality.Type: GrantFiled: March 29, 2018Date of Patent: September 1, 2020Assignee: ABB Schweiz AGInventors: Shaojie Cheng, Diamond Daimeng Dong, Lei Mao

Patent number: 10759016Abstract: A machine tool includes a cover body for separating at least a machining area from the outside. The cover body has an opening for allowing the machining area to communicate with the outside and includes a door for opening and closing the opening. The cover body does not include a transparent window for allowing the machining area to be visually checked from the outside. The cover body can be formed to be of a sufficient strength throughout and, if an unexpected accident occurs, structures within the machining area can be reliably prevented from being shot out of the machining area.Type: GrantFiled: February 23, 2017Date of Patent: September 1, 2020Assignee: DMG MORI CO., LTD.Inventors: Yuki Kimura, Shigetsugu Sakai

Patent number: 10759018Abstract: The present subject matter relates to a method and an apparatus in the form of a machine system (1200) for machining a component (100) with an internal passage (115). In an aspect, the method comprises periodically injecting 5 abrasive slurry back and forth through the internal passage (115) at a pressure ranging from about 25 bar to about 35 bar. The abrasive slurry comprises a mixture of abrasive particles having a size in the range of about 40 ?m to about 60 ?m, and a slurry medium. The volume fraction of the abrasive particles in the slurry medium is about 40% to about 50%. Further, the injection of the abrasive 10 slurry is performed for a predefined number of process cycles at predetermined time versus pressure changes to obtain the component having a final average surface roughness of less than about 3.0 ?m.Type: GrantFiled: August 24, 2016Date of Patent: September 1, 2020Assignee: Sundaram-Clayton LimitedInventor: Telikicherla Venkata Lakshmi Narasimha Rao
