Frequently Asked Questions
A horizontal boring machine performs internal hole machining or boring on large structural components by rotating a boring bar or spindle. It is suitable for high-precision, high-strength, and large-sized parts. The workpiece is typically fixed on the worktable, and the tool moves along multiple axes to achieve deep, multi-directional boring and milling operations.
High-quality horizontal boring machine manufacturers should possess independent R&D capabilities, complete machine processing capacity, stable delivery experience, and global customer cases. Minnuo not only has a full-scale production and assembly facility but also provides international certifications such as CE and ISO to ensure equipment quality and responsive service.
The horizontal boring machine price mainly depends on the boring diameter, worktable size, control system configuration, and whether it includes automatic tool changers or auxiliary modules such as rotary tables and measuring systems. We will provide a detailed quotation based on your process requirements and budget, with options to include transportation and taxes.
Absolutely! Minnuo has a strong and responsive pre-sales technical team. As long as you provide part drawings, whether for a single horizontal boring machine or a complete set of integrated equipment, we can recommend the appropriate model within 10 minutes and deliver a complete solution within 5 working days.
We offer full mechanical processing and electrical integration capabilities. Based on your machining requirements, we can customize the horizontal boring and milling machine in terms of travel distance, boring bar diameter, spindle structure, tool magazine configuration, and control system. We support multiple CNC versions and custom functional modules.
We are equipped with top international machining centers to ensure the precision and stability of all key components in our CNC horizontal boring machines. Each machine undergoes full-scale debugging and load testing before delivery and comes with a complete inspection report to ensure immediate production readiness upon arrival.
We maintain inventory of standard models for fast delivery. For customized horizontal boring machines, the delivery time is usually 30–45 working days, depending on the complexity of the configuration and the production schedule.
All of our equipment comes with a one-year warranty. During the warranty period, any failure will be covered by free repair services. We also provide 24-hour remote technical support (via video or phone), and if necessary, can dispatch engineers on-site to ensure quick production recovery.
