As a leading manufacturer from Henan San Kuang Machinery Technology Co., Ltd. (established in 2014, with a 10,000-30,000 m² factory), we are proud to present our CNC Machine Tool Helical Gear — crafted from high-quality 20CrMo alloy steel and precision ground for superior performance. This gear is specifically designed to reduce noise, extend service life, and ensure reliable transmission in demanding CNC machining environments. With our advanced production capabilities and strict quality control, every gear delivers consistent accuracy and durability.
Key Features & Technical Specifications
- Material Strength: 20CrMo alloy steel provides excellent core toughness and surface hardness after carburizing and quenching, ensuring resistance to wear and fatigue.
- Precision Grinding: All tooth profiles are CNC ground to achieve DIN 6-7 accuracy grade, resulting in smooth meshing and minimal backlash.
- Noise Reduction: Optimized helix angle and tooth geometry significantly reduce operating noise compared to spur gears, ideal for high-speed CNC spindles.
- Long Service Life: Combined heat treatment (carburizing + quenching + tempering) extends gear life by up to 30% under heavy loads.
- Customizable Specifications: Module range M1–M20, various pressure angles, helix angles, and bore sizes are available upon request.

Frequently Asked Questions
Q1: What makes your helical gear quieter than standard spur gears?
Our helical gears have an angled tooth design that engages gradually, reducing impact and vibration. Combined with precision grinding, noise levels are significantly lower.
Q2: Can you customize the gear dimensions to fit my existing CNC machine?
Yes, we offer customization for module, number of teeth, bore diameter, keyway, and helix angle. Please provide your drawings or specifications.
Q3: What is the typical lead time for a custom order?
Lead time depends on complexity and quantity. For standard sizes, 15–20 working days; for custom designs, 25–35 working days.
Q4: Do you provide heat treatment reports?
Yes, we can supply hardness test reports and metallographic analysis upon request.
Q5: What is the minimum order quantity (MOQ)?
MOQ is typically 10 pieces for standard sizes, but we can discuss smaller quantities for trial orders.
Q6: How do you pack the gears for export?
Each gear is individually wrapped with anti-rust paper, then packed in wooden cases or pallets, suitable for sea freight.
Q7: Do you have quality certifications?
Our factory is ISO9001, ISO14000, OHSAS18001 certified, and we follow strict QC procedures including 100% dimensional inspection before shipment.
Q8: Can you provide samples for testing?
Yes, sample orders are welcome. We can produce a sample based on your drawing, with a lead time of 10–15 working days.
