What are precision machined components?
Parts for automotive and other applications require high levels of precision, in order to meet strict international quality and safety regulations. BPG delivers standard volumetric accuracy up to .0065mm and repeatability of .002mm. These close tolerances can only be met with advanced manufacturing technologies, including CNC milling, turning and grinding. Our high-precision machine tools keep part accuracy stable for large numbers of parts, and over long periods of time.
Quality measurement and inspection of precision components require coordinate measuring machines (CMM) and automated 3-D laser measurement vision systems (Keyence capability).
Our History in Machined Components
Since 1976, Burke Porter Group has become a world leader in machined components for the automotive industry, heavy-duty manufacturers, and companies in the entertainment, plastic, and industrial sectors. A turnkey supplier of precision build-to-print components and assemblies, BPG takes ideas from prototype to production with unrivaled craft and accuracy.
Using state-of-the-art equipment, including computer numerically controlled (CNC) grinding, milling, and turning machines, we produce high-precision parts with minimal lead time. With over 80 CNC machines and countless pieces of support equipment, we have the resources necessary for almost any job.
Our multi-axis CNC mills have horizontal and vertical machining capabilities as well as TCP, probing, tool detection, quick change fixturing, pallet changing, and collision avoidance systems. The spindles run 15,000 RPM and are monitored by MasterCam Software.
For precision ground shafts, our CNC grinder features three grinding wheels in a single operation, limiting re-positioning and providing unmatched geometric tolerances. The machine also has diamond and CBN superabrasive capability with rotary diamond dressing to meet extreme tolerances and maximum productivity.
Our CNC turning centers and CNC lathes can hold tolerances down to +/- 0.002 mm. All our machines and processes are ideal for prototypes, tooling, specialty, and low-to-medium volume production runs
Process of Precision Machining
To produce precision machined components, parts designers develop computer-aided design (CAD) software that defines and describes the desired part. Next, machinists use computer-aided manufacturing (CAD) software to tell the CNC machine tools when and how to move in order to create the part to our customers’ exact specifications.
As material is removed from the workpiece, the high accuracy of the CNC tool results in less raw material waste. This is especially important for working with costly materials, such as titanium, castings, and other rare metals. Automated tool magazines shorten the time to change tooling and prevent human error.
Through constant system improvements, we ebsure the accuracy of each part prior to delivery, while our ten CMM machines provide the necessary tools for precisely detailed inspections. Our day-to-day quality program is driven by a number of Automotive Industry Action Group (AIAG) systems. For example, Advanced Product Quality Planning (APQP), Production Part Approval Process (PPAP), Process Control Plans, Process Flow Diagrams, Process Failure Mode Effects Analysis (PFMEA) and Process Capability Studies.
We are proud to be ISO 9001 quality management system compliant and TS 16949:2009 registered specifically for quality and precision in the automotive industry.
