R&J Cylinder & Machine provides high-precision boring services for demanding, heavy-duty applications throughout New Philadelphia, Ohio, and the surrounding region. Our experienced machining team delivers accuracy, straightness, and surface finish that meet or exceed the most stringent specifications—whether the project calls for horizontal boring, vertical boring, or pull boring.
As an ISO-certified machine shop, we work with both ferrous and non-ferrous materials up to 45 HRC hardness. Our facility is equipped to handle large and complex components, including outside diameters up to 33 ¾ inches, inside diameters with tolerances as tight as ±0.010 inches, and lengths exceeding 36 feet depending on OD. When needed, we accommodate stock removal up to 1.00 inch per pass and can support custom or metric dimensions with precision and speed.
Many projects combine boring with precision honing to achieve an optimal finish, improved surface texture, and superior sealing or bearing performance. For hydraulic cylinder manufacturing, roll repair, or general machining, accurate boring ensures every part aligns, fits, and functions as intended.
We also specialize in pull boring (horizontal) to enhance wall thickness uniformity and surface integrity in smaller diameters. Our engineering team oversees every stage of the process—from fixture design to stock removal techniques—to reduce distortion and preserve material strength.
R&J Cylinder is a trusted partner for deep hole boring and precision machining projects across Ohio. Contact our team to discuss your next boring project and experience the quality craftsmanship, reliability, and performance that define our work.
