Product Description
Precision Machining Experts for Machine Tool Bolts
Bolts are the most critical connecting components in machine tools equipment, and their machining quality directly affects the overall machine's accuracy and operational stability. We specialize in the precision manufacturing of machine tools bolts, leveraging advanced machining equipment and professional processes to provide the machine tools industry with high-quality fastener solutions that offer reliable strength, superior precision, and long service life.
Professional Bolt Machining Technology
We are equipped with multiple CNC lathes and precision thread rolling machines, capable of producing machine tool-specific bolts of various specifications, from M8 to M48. Through optimized machining processes and professional tools selection, we ensure that the thread accuracy of our bolts reaches 6g grade, the flatness of the head bearing surface is controlled within 0.02mm, and the straightness error of the shank does not exceed 0.05mm/m. Especially for high-strength positioning bolts, we employ a special heat treatment process to ensure that the product's mechanical properties meet the 12.9 grade standard.

Superior Materials Ensure Product Performance
We strictly select high-quality alloy steel materials such as 35CrMo, 42CrMo, and 45# steel. Each material undergoes a rigorous heat treatment process: 35CrMo possesses excellent comprehensive mechanical properties; 42CrMo has higher strength and is suitable for heavy-duty applications; 45# steel offers excellent cost-effectiveness and good machinability. All materials are sourced from renowned suppliers, and complete material certificates and heat treatment reports are provided for each batch.
Advanced Processes Guarantee Processing Quality
Machine tools bolt processing faces technical challenges such as thread precision control, heat treatment deformation, and high surface quality requirements. We effectively solve these problems through innovative processes: employing a dedicated thread rolling process to improve thread surface strength and precision; utilizing controlled atmosphere heat treatment technology to effectively control deformation; and ensuring the bearing surface achieves the required flatness and smoothness through precision grinding.
Comprehensive Quality Assurance System
We have established a complete bolt inspection process, equipped with professional equipment such as thread measuring instruments, hardness testers, and metallographic analyzers. In addition to routine dimensional inspections, we also conduct comprehensive performance tests on bolts, including tensile tests, torque tests, and fatigue tests. We establish complete quality records for each batch of products to ensure that all products leaving the factory meet the stringent requirements of the machine tool industry.
Our machine tools bolts are widely used in various machine tools such as CNC machine tools, machining centers, and precision grinding machines. With professional manufacturing technology and rich processing experience, we are committed to providing every customer with the highest quality bolts, using precision manufacturing processes to provide reliable assurance for the stable operation of machine tool equipment.
