一、Product Description of the CNC Milling Machine Tool Holder

This OEM CNC Milling Machine Tool Holder is a core component for high-precision machining centers. Commonly known in the industry as the BT30 Tool Holder, it is compatible with various types of vertical CNC milling machines and is an indispensable tool holder for high-volume milling operations. The product is manufactured from high-quality 42CrMo alloy structural steel. It features a design without surface treatment—no coatings or oxide layers are applied—preserving the steel’s original metallic structure and eliminating common issues such as coating peeling, surface deformation, and loss of precision that occur during long-term high-speed cutting.

Dongguan Shengpeng can independently complete the full production process for precision CNC turned parts, utilizing a multi-stage machining approach. standardized turning services are used to shape conventional blanks, while high-precision tapered surfaces and flange structures are entrusted to professional precision CNC turning services for finishing. We support full-scale OEM customization based on customer drawings, samples, and machine tool accuracy requirements, catering to various machining scenarios such as mold finishing and bulk hardware milling. The finished products feature stable concentricity, minimal vibration during high-speed cutting, and controllable dimensional errors over the long term.

三、Manufacturing Process for Precision CNC Tool Holders

First, 42CrMo round bar is cut to size. Rough turning is performed using Turning Services to shape the blank and outline the basic contours of the tool holder’s tapered shank and flange. The semi-finished product is then transferred to the finishing station, where Precision CNC Turning Services are used to perform mirror-finish turning on the tapered surface and locating steps, with strict control over dimensional tolerances; Upon completion of machining, low-temperature stress relief treatment is performed to eliminate internal stresses. No surface treatments such as electroplating, blackening, or coating are applied throughout the process. After all processes are completed, multiple dimensional inspections are conducted; upon passing inspection, the parts are stored as finished, bare-metal CNC-turned parts.
