Features & Benefits
Segmented, finger-style elastic structure, specifically designed for complex geometric surfaces
The Finger-Style Sisal Wheel is an elastic polishing tool designed specifically for complex geometric surfaces. Its unique segmented, finger-style folding design allows each independent segment to flexibly open and close, providing ample elastic cushioning space. It conforms perfectly to the arcs of tubing, bent pipes, castings with uneven surfaces, and curved door and window components. Compared to standard full-circle sisal wheels, it ensures no areas are missed when polishing grooves and corners, resulting in a uniform and consistent finish. With excellent surface adaptability, it effortlessly handles workpieces of various irregular shapes.
Available in industry-leading large sizes, it covers a wider area with each pass, reducing the number of back-and-forth movements required for the workpiece and effectively shortening the polishing time per piece. It is suitable for 24-hour fully automated continuous mass production, significantly improving production efficiency while ensuring polishing quality.
Made from sisal fibers with moderate hardness, these wheels combine strong scratch-removal and scale-removal capabilities without causing excessive erosion to workpieces, unlike red oil-soaked sisal wheels. When polishing copper, aluminum, zinc alloys, and thin stainless steel parts, they prevent blackening and scratching. Polishing residue is easy to clean and does not contaminate the substrate prior to electroplating or spray coating, making them an ideal choice for rough polishing of golf club heads, gravity castings, and stainless steel products.
A thickened metal tooth ring at the center securely holds each segmented sisal pad in place, while multi-layer stitched edges provide resistance to tearing and delamination. Each wheel undergoes professional dynamic balancing calibration before leaving the factory, ensuring smooth, vibration-free operation at safe speeds. Even with long-term assembly line use, it is resistant to fiber fly-off and pad detachment, resulting in a longer service life.
The gaps between the layers form natural ventilation and heat dissipation channels, rapidly dissipating heat during high-speed friction and preventing workpieces from being scorched or blackened by high temperatures. The virgin hemp material retains wax evenly, resulting in lower wax consumption. When used with yellow wax and purple wax for coarse polishing, it reduces downtime caused by frequent wheel changes and wax replenishment, effectively cutting polishing consumable costs.

Manufacturing Process
1. Sisal Rope Binding and Molding
Carefully selected high-quality sisal fibers are bound and compacted to a standard weight, ensuring uniform fiber density and laying the foundation for strong cutting performance.
100% Cotton Fabric Wrapping + Precision Stitching
2. The bundled sisal rope is fully wrapped in 100% cotton fabric and secured using a double-thread, close-stitch process to create individual elastic finger pads, enhancing overall toughness and cushioning elasticity.
3. Radial Layered Assembly and Locking
Multiple sisal finger pads are arranged radially and evenly along the inner circumference of the metal tooth ring, stacked in multiple layers and compacted. The metal teeth securely grip and lock all the sisal pads in place, resulting in a full and uniform working surface after molding.
4. Dynamic Balancing Calibration
All finished products undergo high-precision dynamic balancing calibration to ensure smooth operation at the rated speed. Finally, each unit undergoes a full manual inspection for dimensions, elasticity, and density before being packaged and shipped.

Frequently Asked Questions About Procurement
What is the key difference between this finger-style sisal wheel and a standard sisal wheel?
Standard eight-strand sisal wheels have a one-piece, full-circle structure that does not conform well to curved surfaces, often missing deep grooves and curved workpieces during polishing. This model features an independent, finger-style design where each sisal segment can bend individually, offering greater flexibility and allowing it to closely conform to bent pipes, castings, and irregular convex or concave surfaces. Additionally, its 18-inch extra-large working surface allows for a larger single-pass grinding area, making it ideal for processing large-volume, oversized workpieces.
What is the hardness of this white finger-style sisal wheel, and will it scratch soft metals?
This product is made from natural white sisal treated with a resin-softening process, offering moderate hardness and gentle, balanced cutting action. It leaves a fine surface texture after polishing and is suitable for rough polishing of precision irregular parts such as golf club heads and gravity castings.
What steps are involved in the complete manufacturing process for an octagonal twisted rope polishing wheel?
Made from select Grade A long-fiber sisal, this rope is woven from 8 twisted strands → secured around a galvanized steel core with evenly spaced, radial teeth → compacted through multi-layer stacking → reinforced with a locked outer edge; optional oil-soaking, sizing, drying, and hardening processes are available. All finished products undergo dynamic balancing calibration and are packaged after manual quality inspection for dimensions and density.
For which polishing processes is the 18-inch finger sisal wheel suitable? Can it be used directly for mirror finishing?
It is primarily designed for rough and medium-rough polishing processes. It can quickly remove casting burrs, parting lines, deep and shallow scratches, and black oxide scale, while leveling uneven workpiece surfaces to lay the foundation for mirror polishing. It is intended solely for pre-treatment and roughing; it cannot achieve a mirror finish on its own. After rough polishing, a cotton wheel or wool wheel must be used in conjunction with fine polishing wax to enhance the shine.
Which industries, workpieces, and metal materials is it suitable for?
Suitable for bathroom hardware, locks, kitchenware and tableware, metal furniture, architectural and decorative tubing, golf accessories, and gravity castings; it can process various metals such as stainless steel, iron, copper, titanium, carbon steel, zinc alloy, and aluminum alloy.
What polishing equipment is it compatible with, and can the center hole be customized?
The 18-inch large size is compatible with fully automatic continuous polishing production lines, large vertical polishing machines, and specialized tube polishing machines; standard inner holes include round, square, and hexagonal socket holes. The outer diameter, thickness, and inner hole dimensions can all be customized according to the customer’s equipment requirements.
Which polishing waxes provide the best results? Which waxes are not recommended?
We recommend using yellow coarse-polishing wax and purple medium-coarse polishing wax first, as they are most effective at removing scratches and oxide layers. We do not recommend using white wax, green wax, or other mirror-finish polishing waxes, as their fibers are too soft and prone to slipping, which significantly reduces their ability to remove imperfections.
What causes the pads to shed pieces or fray during polishing, and how can this be resolved?
When used properly according to specifications, shedding is extremely rare. Significant shedding is typically caused by exceeding the recommended speed, applying excessive pressure, or prolonged dry polishing that causes the fibers to burn due to high temperatures. To minimize wear, control the speed, apply light and even pressure, and continuously replenish polishing wax for lubrication. The product is reinforced with multiple layers of stitched edging at the factory and is wear-resistant and durable under normal operating conditions.
What is the purpose of the gaps between the individual polishing faces?
The gaps between the separate polishing faces create natural ventilation and heat dissipation channels. During high-speed polishing, they rapidly dissipate frictional heat, preventing the workpiece from turning black or being scorched due to high temperatures, and ensuring better stability during prolonged continuous assembly line operations.
What are the standard sizes in stock, and what is the lead time for custom orders?
For special thicknesses, special inner diameters, or custom colors, the standard lead time is 15–20 business days. Expedited production can be arranged for large-volume orders upon request.
