Bracalente Manufacturing Group (BMG) has a 65 year long track record of machining parts and components with industry leading precision. Today, our CNC turning services are the centerpiece of our high precision machining capabilities.
CNC Turning Services at BMG
Our Trumbauersville, PA headquarters is Certified to ISO 9001:2015 as well as AS9100 Rev D and our second plant in Suzhou, China is Certified to ISO 9001:2015 as well as TS16949 — we operate more than 75 CNC turning machines. Our CNC turning machines are manufactured by industry specialists, including::
- Mori Seiki
We bar feed our lathes up to 3” (75mm) in diameter and chuck work pieces up to 10” (254mm) in diameter. We are also equipped to perform a wide variety of CNC turning processes:
- Hard turning — A process designed to replace grinding processes used for hardened materials.
- Facing — Facing creates a large planar surface, or a face, on an end of the workpiece.
- Grooving and face grooving — The process of cutting grooves of predetermined depth into the sides or face of a workpiece.
- Drilling — Used primarily to remove material from the interior of a workpiece beginning at its face, more advanced CNC turning machines can stop workpiece rotation and drill or mill off center or cross center to work piece.
- Boring — The process of enlarging pre-drilled holes with a single-point tool.
- Reaming — The process of enlarging pre-drilled holes with a multi-fluted tool designed to cut to size of the diameter of the tool.
Turning is one of the oldest machining processes — it has roots in ancient Egypt, Assyria, and Greece — and also, at its core, one of the most basic.
In turning, a base material in bar form is spun rapidly around its center on a lathe. One or more cutting tools, generally non-rotary tool bits of various forms, move along the workpiece linearly, removing material from the spinning workpiece as it moves.
In modern manufacturing scenarios, virtually all turning is performed on CNC turning machines. Fully automated, CNC turning machines are capable of producing fully completed pieces with a high degree of precision, holding even the tightest of tolerances, using robotic automation and tool load censoring to optimize tool life.
