Pipe machining apparatuses and bearing assemblies are provided. In one aspect, a pipe machining apparatus includes a frame, a tool carrier, a first roller bearing and a second roller bearing. The tool carrier is coupled to and movable relative to the frame and defines a race therein. The first roller bearing includes a first shaft and a first roller rotatably coupled to the first shaft. The first roller is at least partially positioned in the race and is rotatable about a first roller bearing axis adapted to remain substantially fixed relative to the frame. The second roller bearing includes a second shaft and a second roller rotatably coupled to the second shaft. The second roller is at least partially positioned in the race and is rotatable about a second roller bearing axis. The second roller bearing is adjustable to move the second roller bearing axis relative to the frame.

A safe mode cross slide system having a cross slide with a back plate, a front plate and a saddle. The back plate can have a pair of end caps, a pair of linear guides, a first ball screw, a first gear box, a first servo motor, a first drive, and a first manual feed knob and the front plate can have a pair of end caps, a pair of linear guides, a second ball screw, a second gear box, a second servo motor, a second drive, and a second manual feed knob. The system can have a power supply, a communications hub with a processor and data storage.

A housing component includes a flange defining a center point and having an end face formed with microstructures in a first region and a second region to increase a local friction coefficient. The microstructures have each a blade shape with a cutting line, the cutting line in the first region being arranged concentrically about a first local center point, and the cutting line in the second region being arranged concentrically about a second local center point. The first and second local center points have different radial distances from the center point of the flange.

A sealing surface processing machine cuts an attachment surface of a seal member in a valve main body. The machine includes a pedestal attached to the valve main body; a main body movably supported on the pedestal; a tool holder configured to hold a tool for processing the attachment surface; a rotating part configured to rotate the tool holder around an axis parallel to a movement direction of a valve body; a first moving part configured to move the tool holder along a first direction along which the valve body moves; a second moving part configured to move the tool holder along a second direction intersecting with the movement direction of the valve body; a first adjustment device configured to adjust a position of the main body in the first direction; and a second adjustment device configured to adjust a position of the main body in the second direction.

Disclosed is an orbital cutting apparatus that is capable of freely and selectively controlling forward and backward movement of a plurality of cutting tools, allowing the cutting tools to move forward and backward and to move in an axial direction of a material to be cut so as to enable processing of various shapes as well as cutting and chamfering, and is capable of simultaneously carrying out cutting and chamfering operations for a pipe material or a heavy pipe having a thickness of dozens of mm or more.

A method of using a pipe machining apparatus according to an aspect includes providing a frame capable of being mounted onto a pipe, a tool carrier coupled to and movable relative to the frame, a tool support coupled to and movable with the tool carrier relative to the frame, and a laser line generator tool mounted on and movable with the tool support. The laser line generator tool images a laser light onto the pipe to align with a mark(s) on the pipe which denotes a proper cut line around the pipe. The apparatus can be repositioned relative to the pipe in order to enable an operator to properly position the apparatus on the pipe prior to a cutting operation.

In one example, a pipe machining apparatus is provided and includes a frame, a tool carrier coupled to and rotatable relative to the frame, a first machining apparatus including a first tool support and a first tool supported by the first tool support and a second machining apparatus including a bridge member, a second tool support supported by the bridge member, and a second tool supported by the second tool support. The first tool is configured to perform a first machining operation and the second tool is configured to perform a second machining operation different than the first machining operation. The first machining apparatus and the second machining apparatus are interchangeably couplable to and rotatable with the tool carrier.

Pipe machining apparatuses and bearing assemblies are provided. In one aspect, a pipe machining apparatus includes a frame, a tool carrier, a first roller bearing and a second roller bearing. The tool carrier is coupled to and movable relative to the frame and defines a race therein. The first roller bearing includes a first shaft and a first roller rotatably coupled to the first shaft. The first roller is at least partially positioned in the race and is rotatable about a first roller bearing axis adapted to remain substantially fixed relative to the frame. The second roller bearing includes a second shaft and a second roller rotatably coupled to the second shaft. The second roller is at least partially positioned in the race and is rotatable about a second roller bearing axis. The second roller bearing is adjustable to move the second roller bearing axis relative to the frame.
