As a leading pulley CNC Machining specialist, EMAR Company delivers high-performance components for mechanical transmission systems across industries. Our ISO-certified facility combines advanced 5-axis CNC technology with aerospace-grade materials to manufacture pulleys that meet stringent tolerance requirements (±.005mm).

Why Choose CNC Machining for Pulley Manufacturing?

Traditional pulley production methods struggle to achieve the geometric complexity and surface finish requirements of modern applications. Our CNC machining process enables:

• Precision groove profiles (V-belt, timing, flat) with Ra .8μm surface finish
• True concentricity between bore and outer diameter
• Custom lightweight designs with optimized wall thickness
• Material versatility (aluminum 6061-T6, stainless 303/304, brass C360)

EMAR's Technical Capabilities in Pulley Production

Our 15,000 sqm facility features Mori Seiki NVX500 CNC mills and Okuma MULTUS U300 turning centers capable of producing pulleys from 10mm to 800mm diameter. All components undergo CMM inspection (Zeiss CONTURA G2) with full traceability documentation.
