Reverse Engineering Splines and Gears: Accurate Spline Measurement and Broaching Tool Quotes

CNC Broach Tools offers specialized reverse engineering services for internal and external splines, gears, and complex broaching applications. Our precise spline measurement capabilities help customers efficiently manufacture replacement parts using single-point broaching, blind broaching, and single or multi-tooth broaching techniques. Our expert measurement services start at $350, providing precise dimensional data alongside a detailed broach tooling quote customized to your specific spline and broaching needs.

Preparing Splines and Parts for Measurement

To ensure accuracy, we ask that all spline components sent for measurement be thoroughly cleaned, degreased, and free from dirt and debris. Parts must be fully disassembled, with any coverings, seals, or obstructions removed prior to shipping.

Additional Charges for Unprepared or Difficult Parts

Recently, we’ve received many parts requiring extensive cleaning, degreasing, disassembly, or even cutting and sectioning due to inaccessible splines. To handle these additional preparations, we charge $100 per hour. Typical scenarios include:

1. Dirty or greasy spline parts: Additional cleaning and degreasing fees apply.
2. Disassembly required: Extra charges for disassembling parts upon arrival.
3. Sectioning for deep or blind splines: Additional hourly fees for cutting or sectioning parts to measure otherwise inaccessible splines.

Additional charges will be assessed once your parts arrive and undergo initial inspection.

Best Practices for Sending Your Spline Components

To streamline our reverse engineering process, minimize delays, and avoid additional costs, we recommend:

1. Providing a cross-section of the spline whenever possible.
2. Ensuring all spline components are clean, degreased, and ready for immediate measurement.
3. Clearly noting any obstructions or challenging features that might necessitate extra handling or sectioning.

Advanced Spline Measurement Capabilities

Our primary measurement equipment, the Keyence LM-1100, has a 3-inch vertical measurement (Z-axis) capacity. For splines that exceed this limit or are too deep to measure directly, we typically use dental molding compound to create precise impressions. However, in cases where mold impressions are inadequate due to spline depth or complexity, we may need to cross-section the part, incurring additional hourly charges.

Broach Measurement and Reverse Engineering Fees

1. Standard reverse engineering service: $350
2. Extra labor (cleaning, disassembly, sectioning): $100/hour

Following these guidelines ensures efficient and accurate spline measurements, helping you quickly transition to broaching your precision spline components. We appreciate your cooperation and look forward to providing exceptional spline measurement and broaching tooling solutions
