Product Description
Brief Introduction
This custom 5-axis CNC machined aluminum heat sink timing pulley comes with sandblasted surface finish. Made of premium aluminum alloy, it combines timing belt transmission and heat dissipation structure in one integrated part. With high mechanical strength, lightweight and excellent thermal conductivity, it is widely used for power transmission in automation equipment, motors and machinery. OEM & ODM custom machining service available, factory direct supply with reliable quality.
Product Overview
This integrated pulley part is manufactured by advanced 5-axis CNC milling. The outer timing gear teeth, radial heat dissipation ribs and central mounting flange are completed in one clamping process, ensuring high concentricity and stable running performance. Sandblasting treatment removes machining tool marks and forms uniform matte metal texture, improving surface wear resistance.
All finished parts go through strict dimensional inspection before shipment. We accept custom manufacturing according to your CAD drawings or physical samples. Both prototype trial orders and mass production orders are supported.
Key Features
- Premium aluminum alloy material, lightweight with good thermal conductivity
- 5-axis CNC integrated machining, timing tooth + heat sink rib combined design
- Sandblasted surface finish, uniform matte texture and scratch resistance

FAQ
Q1: What material is this sandblasted aluminum timing pulley?
A: Standard material is 6061 aluminum alloy with sandblasted finish. We also support 6063 and 7075 aluminum alloy for custom orders.
- 6061: General purpose, balanced strength and machinability, most widely used for CNC pulley parts.
- 6063: Excellent anodizing performance for uniform surface appearance.
- 7075: High-strength aerospace aluminum for heavy-load applications.
Q2: Can you produce according to my 2D or 3D CAD drawings?
A: Yes. Please send us your files in STEP, IGES or PDF format. Our engineering team will evaluate your drawing and provide quotation. We also accept physical samples for reverse engineering.
Q3: What is sandblasted finish? Can I choose other surface treatments?
A: Sandblasting is a surface processing method to create uniform matte metal texture and remove tool marks. Other available options include clear anodizing, black anodizing, brushing and polishing.
Q4: What is your MOQ? Can I order 1 piece for sample testing?
A: MOQ is 1 piece. We support prototype sample before mass production.
Q5: What is your production lead time?
A: Sample order: 3–7 working days. Mass production: 7–20 working days depending on order quantity.
Q6: How do you guarantee product quality?
A: We inspect dimensions with calipers, micrometers and CMM. Every part will be checked before packing. Inspection reports can be provided upon request.
Q7: What is T/T payment term?
A: T/T stands for Telegraphic Transfer, also known as wire transfer. It is the most common international payment method. For sample orders, we accept 100% T/T in advance. For bulk orders, common terms are 30% T/T deposit before production and 70% T/T balance before shipment.
Q8: Can you also make parts from stainless steel or alloy steel?
A: Sure. We manufacture custom turned and milled parts in aluminum, stainless steel, alloy steel, brass and engineering plastics.

JThey delivered exactly that. No loose machining swarf in internal channels, passivation per ASTM F86 after machining, and lot numbers laser-marked on each piece so we can trace back to the raw material batch. Our QA team didn't send a single part back. Pricing is mid-range not the cheapest quote we got, but the documentation saved us more in internal inspection time than the premium cost.

JThey are small but very sturdy; I hope the quality stands the test of time.

DThe one-piece machined bracket fits our motion module perfectly. No distortion after anodizing. Sample lead time was shorter than we expected. We will launch mass production order soon.
