Product Overview
At Hansheng Automation, we provide professional gear broaching services . With over a decade of experience in custom precision gear manufacturing, our gear broaching capabilities are specifically optimized for internal gear production - Whether it's small to medium batch orders or large-scale production, we can ensure consistent processing accuracy and surface smoothness through our unique customized puller.
Gear broaching is a highly efficient metal-cutting process that removes material using a multi-tooth broach tool in a single linear stroke. This process is suitable for internal gears and spline gears with extremely high dimensional consistency, and has excellent processing efficiency and production capacity in mass production through customized cutters(the broach).
Why Choose Our Gear Broaching Services?
Unlike shaping or milling, gear broaching removes all material in a single linear stroke, significantly reducing cycle times from minutes to seconds.
Once the broach tool is calibrated, every part in a 10,000-unit run will maintain identical tolerances, ensuring perfect interchangeability.
Unlike standard machining operations, gear broaching relies on purpose-built tooling. At Hansheng, all broaches are custom-manufactured to match the exact gear specifications provided by our customers. This means you get a broach optimized for your specific module, pressure angle, number of teeth, and material.
For large batches, the high initial tool cost is offset by the incredibly low labor and machine-time costs, providing you with the best ROI.
We are equipped with a full range of advanced gear manufacturing equipment, such as the NACHI gear broaching machine series, Kashifuji gear skiving machine KPS30, Ningjiang CNC horizontal gear hobbing machine, CMM, gear measuring instrument, hardness tester, etc.

FAQ
Q: What is the typical lead time for a new gear broaching project?
A: Due to the need for custom-made broach tools for gear broaching services, the initial delivery cycle may include a tool manufacturing time of about 2 axes, but as long as the tools are in place, subsequent production will be very fast.
Q: Does Hansheng Automation provide broaching for blind holes?
A: The traditional gear broaching requires that the workpiece must have a through hole for the puller to pass through. For blind hole machining needs, we usually recommend customers to choose our "Gear skiving" or "Gear Shaping" services to achieve the desired tooth profile.
Q: What is the Minimum Order Quantity (MOQ) for broaching?
A: Due to the cost of custom broach tooling, our gear broachingservices are generally only available for medium to large volume orders. For small batch orders, we recommend using CNC shaping or skiving machining methods, MOQ:5
Q: How do you ensure the quality of broached splines?
A: We utilize dedicated spline gauges and CMM (Coordinate Measuring Machine) inspections to ensure every internal profile meets the specified GB/ISO grade.
Q: What equipment do you use for high-precision internal broaching?
A: We rely on Nachi (Fujikoshi) Broaching Machines, a global leader in broaching technology. This allows us to offer our clients the perfect balance of Japanese engineering precision and cost-effective manufacturing for internal gears and splines.
