A new and improved microfabrication device, microfabrication method, transfer mold, and transfer object that can suppress a defect are provided. A microfabrication device comprises a tool mounting portion, a predetermined cutting tool, an oscillator, and a controller, wherein the controller performs a cutting process to satisfy at least one of: a cutting condition (1) that oscillations at a start point and an end point of each set are in phase with each other; and a cutting condition (2) that oscillations of the sets are in phase with each other.

A process for manufacturing a hollow roller of a roller bearing including steps of: machining an outer radial cylindrical surface, with a circular cross section centered on a first axis, and machining an inner radial cylindrical surface with a circular cross section centered on a second axis. These two steps are realized on the same lathe. The hollow roller is provided with the outer radial cylindrical surface, with a diameter of at least 5 mm, and the inner radial cylindrical surface. An offset between the first axis and the second axis, measured in the hollow roller between two axial surfaces of the hollow roller, is less than 2 m, and an inclination angle between the first axis and the second axis is less than one minute of angle. The roller bearing comprises amongst others, at least one such hollow roller.

A production method for a ring-shaped part is provided with: an inner cutting step for reciprocating a first cutting blade in the radial direction D4 from a state of contact with the center of the thickness of one end 91a of a rotating cylindrical blank 91 and moving toward the other end 91b in the axial direction D1 to form a semicircular track while cutting the inner circumferential R1-side of the cylindrical blank 91; an outer cutting step before, after or simultaneously with the inner cutting step for reciprocating a second cutting blade in the radial direction D4 from a state of contact with the center of the thickness of the one end 91a of the rotating cylindrical blank 91 and moving toward the other end 91b in the axial direction D1 to form a semicircular track while cutting the outer circumferential R2-side of the cylindrical blank 91; and a separation step after the inner cutting step and the outer cutting step for cutting the portion 92 of the cylindrical blank 91, the inner circumferential R1-side and the outer circumferential R2-side of which have been cut, from the remainder 93 of the cylindrical blank 91 to obtain a ring-shaped part 94 with a roughly circular cross-section.

Portable lathes, portable lathe assembly kits, and associated methods. A portable lathe comprises two frame members, a plurality of guide bars, a tool assembly supported by the guide bars, and a feed assembly for translating the tool assembly along the guide bars. The feed assembly includes a first fixed linear feed element, a second fixed linear feed element, a driving rotary feed element, and a driven rotary feed element, and is configured such that rotating the driving rotary feed element translates the tool assembly along the guide bars. A portable lathe assembly kit comprises components of the portable lathe configured to be assembled together to install the portable lathe on a cylindrical workpiece. In some examples, a method of utilizing the portable lathe assembly kit comprises operatively receiving the cylindrical workpiece within the frame members by securing the cylindrical workpiece to a first lathe clamshell subassembly and operatively coupling a second lathe clamshell subassembly to the first lathe clamshell subassembly.
