CNC Turning Improves Productivity & Produces Better Quality Control

CNC turning has brought about a revolution in manufacturing by enabling improved productivity and superior quality control. One of the critical aspects of this transformation is the role of 5-axis machining. By utilizing five different axes simultaneously, 5-axis machining allows for the creation of incredibly complex parts with a single setup, enhancing productivity significantly. Additionally, this advanced CNC turning machining technique reduces the risk of error and increases precision, contributing to better quality control.


The effectiveness of a CNC turning center in achieving high precision and productivity is unparalleled. These centers, a mainstay of any reputable CNC machine shop, facilitate seamless and efficient production of various parts. The state-of-the-art technology of the CNC turning center not only allows for precise control over the manufacturing process but also accelerates the turnaround time, maximizing productivity.


The scope of services provided by CNC turning extends to a variety of specialized processes. From Kovar machining, known for its controlled expansion characteristics used in glass-to-metal and ceramic-to-metal bonding, to Inconel machining, renowned for its resistance to extreme environments and high temperatures, CNC turning provides unparalleled accuracy and consistency. The transformative impact of CNC turning on productivity and quality control has set new standards in the manufacturing industry, making it an indispensable tool for today’s competitive market.

How Does CNC Turning Work & What Does it Produce?

CNC machine shops use CNC turning for those projects that CNC Swiss Turning isn’t quite appropriate for handling. Our precision CNC turning department handles both short and long-running jobs. We need at least 6-8 weeks of lead time, depending on your capacity, but can provide a quick turnaround on your projects to ensure you get your parts on time.


We are fully ISO 9001: 2008 certified and provide first-article inspections upon request. Our process can work with multiple metal types, including aluminum, beryllium copper, brass, bronze alloys, carbon steel, copper, stainless steel, and more. It can also work with several plastic polymers, including Teflon, PVC, reinforced plastics, and even nylon.


CNC turning works by placing appropriate materials in a computer-controlled lathe. We program your part’s size, shape, and material into the turning machine and track its progress. The machine quickly spins your part to cut away materials and provides you with an accurate and precise product. Our machining specialists do not shy away from extremely tight tolerances. In this way, we serve the aerospace, automation, biotech, defense, dental, medical, fiber optic, gas, and semiconductor industries.


When used properly, this process can produce coupling shafts, dowels, drive shafts, handles, fasteners, bushings, axles, bolts, armatures, nozzles, needle valves, electronic hardware, punch blanks, housings, needle valves, knobs, nozzles, pins, pivot robs, sleeves, spacers, valve bodies, and valve stems. Cer-Mac Inc. truly is the one-stop machining shop for all of Bucks County, PA!
