CJWinter® manufactures the premier line of thread rolling attachments, thread rolls, specialty dies and tooling for multi-spindle and CNC machines.
C. J. Winter Machine Works, Inc. (later changed to CJWinter Machine Technologies, Inc.) was incorporated in 1956 and acquired by Robert J. Brinkman in 1969. In continuous operation since then, CJWinter is known worldwide for its high-quality thread rolls, easy-to-adjust thread rolling attachments, competitive pricing and the industry's fastest turnaround times.
Initially focused on the manufacture of tooling and accessories for the Davenport screw machine, Mr. Brinkman pioneered the development of the pneumatic thread-rolling attachment. At the same time, CJWinter also began to expand its product offerings to include a complete line of thread-rolling dies both for its own attachment as well as for those from other manufacturers.
Today, CJWinter is one of the world’s leading manufacturers of cold-displacement, cylindrical dies and attachments. CJWinter’s products are found in traditional thread-rolling applications such as those used with multi-spindle screw machines, rotary transfer machines and CNC – lathes. CJWinter’s products and dies are also found in specialty applications like cold-root rolling used by the oil and gas industry and in industries using dedicated rolling, forming and shaping mills.
CJWinter sells and services its products around the world and has installations in multiple countries on every continent except Antarctica. Renowned for its friendly customer service, expert technical assistance, fast delivery and custom engineered solutions, CJWinter should be your first choice when it comes to your material forming needs.
