North American Golf Equipment Brand × Honscn Precision CNC Machined Brass Putter Heads from Prototype to 5,000+ Production Units
Client & Project Overview
Our client is a premium golf equipment brand serving serious golfers, club builders, and competitive players across North America.
The company specializes in high-end custom golf products where performance, feel, and craftsmanship matter just as much as appearance. For this project, the client wanted to develop a distinctive CNC machined brass putter head that would stand out in both performance and aesthetics.
The goal was ambitious:
- Exceptional putting feel
- Precise center-of-gravity control
- Consistent head weight
- Premium anti-glare satin finish
- Production-ready quality from the very first prototype
What started as a 10-piece prototype run eventually grew into 1,000-piece production orders, followed by a 5,000-piece repeat order, and has since developed into a stable long-term manufacturing partnership.
Product Overview
- Product: Precision Brass Golf Putter Head
- Material: C3604 / H59 Free-Cutting Brass
- Manufacturing Process: Multi-Axis CNC Milling
- Surface Finish: Fine Polishing + 150# Glass Bead Blasting
- Inspection Method: 2D Vision Measurement System
- Application: Premium Custom Golf Putters
Unlike many consumer-grade putters, this design required extremely tight control over weight distribution and face geometry.
For professional golfers, even a small deviation can affect:
- Swing weight
- Ball roll characteristics
- Impact feel
- Visual confidence at address
Key Challenges
1. Maintaining Weight Consistency in Brass
Challenge
Brass provides a soft and responsive impact feel that many golfers prefer. However, its high density also creates a manufacturing challenge.
The client required every putter head to stay within an extremely tight weight tolerance.
A variation of just a few grams could alter the club's swing weight and change the player's feel during putting.
Our Solution
We selected high-quality stress-relieved brass material and optimized the machining strategy to maintain consistent material removal throughout production.
Every completed putter head underwent individual weight verification, with final head weight controlled within ±0.8 grams.
2. Precision Milling of the Putter Face Grooves
Challenge
The face grooves are one of the most critical features of a putter.
Groove depth, spacing, and edge sharpness directly influence:
- Initial ball launch
- Forward roll
- Impact feedback
Even minor tool wear can affect groove consistency during production.
Our Solution
We developed a dedicated machining process using custom tooling and optimized cutting parameters.
The grooves were machined in a single precision operation, eliminating tool-path transitions and ensuring:
- Uniform groove depth
- Consistent spacing
- Sharp, burr-free edges
The result was a clean face pattern that delivered consistent ball performance across every production batch.
3. Achieving a Premium Anti-Glare Satin Finish
Challenge
The client wanted a luxurious champagne-gold appearance that looked premium without creating reflections on sunny golf courses.
Achieving this finish required balancing two opposing processes:
- Polishing removes machining marks
- Blasting creates the matte texture
Too little polishing would leave visible tool marks.
Too much polishing would soften the crisp geometry of the putter.
Our Solution
We developed a dual-stage finishing process:
Step 1: Fine Hand Polishing
Experienced technicians carefully polished all visible surfaces while preserving sharp edges and design details.
Step 2: 150# Glass Bead Blasting
The putter heads were then processed using imported 150# spherical glass beads under tightly controlled blasting pressure.
This created:
- Uniform satin texture
- Complete anti-glare performance
- Premium champagne-gold appearance
- Improved surface durability
The final finish became one of the defining visual features of the product.
Manufacturing Process
Material Preparation
High-quality brass stock was selected and stress-relieved prior to machining.
Multi-Axis CNC Milling
Using high-precision CNC machining centers, we adopted a two-stage strategy:
- Rough machining
- Stress stabilization
- Precision finishing
This minimized internal stress and prevented distortion.
Face Groove Machining
Custom milling tools produced perfectly aligned face grooves with exceptional consistency.
Surface Finishing
- Precision polishing
- 150# glass bead blasting
- Final cosmetic inspection
Quality Control
Every critical dimension was verified using a high-precision vision measurement system.
Inspection items included:
- Hosel bore position
- Perpendicularity
- Coaxiality
- Face groove dimensions
- Step dimensions
- Head weight
All critical characteristics received 100% inspection.
From 10 Prototypes to 5,000+ Production Units
Stage 1: Prototype Development
The project began with 10 prototype putter heads.
The client assembled complete clubs and conducted extensive testing, including:
- Putting performance evaluation
- Sound feedback analysis
- Ball roll testing
- Outdoor anti-glare testing
The response was overwhelmingly positive.
The brand especially praised the soft impact feel and elegant satin appearance.
Stage 2: First 1,000-Piece Production Order
Following successful testing, the customer immediately placed an order for 1,000 units.
To improve production efficiency, we developed:
- Multi-station fixtures
- Standardized machining parameters
- Tool-life monitoring systems
The first production batch achieved an excellent first-pass yield rate.
Stage 3: 5,000-Piece Repeat Order
After launch, the product received strong market feedback.
The customer quickly expanded production and placed an additional 5,000-unit order.
Because the manufacturing process had already been standardized during the prototype and pilot production stages, we were able to ensure that:
- The 5,000th putter matched the first prototype
- Weight remained consistent
- Surface finish remained uniform
- Face groove geometry remained unchanged
The project has since evolved into a stable, ongoing production program.
Customer Feedback
Throughout the project, we maintained regular communication regarding production, inspection, packaging, and shipment status.
After receiving the finished products, the customer shared a simple but meaningful message:
“Perfect!”
Later feedback from the product development team highlighted:
“The finish quality is incredibly consistent. The face milling performs exactly as intended, and the inspection reports gave us complete confidence throughout production.”
