Table-Type Boring Machines from Johnford & You Ji

What Makes Our Table-Type Boring Mills Stand Out?

Johnford BMC Series: Engineered for Maximum Rigidity and Precision

• Heavy-Duty Construction: The Johnford BMC Series stands out for its massive and robust construction. This design not only enhances rigidity but also ensures consistent performance under demanding conditions. It’s built to withstand heavy table loads without the need for additional supports, making it ideal for handling large and heavy workpieces with ease.
• Advanced Design for Precision: Featuring a moving column for the Z-axis and a moving table for the X-axis, the Johnford BMC Series is engineered to provide maximum rigidity and accuracy. The unique design ensures full support of the table over the entire X-axis travel, eliminating any possibility of overhang and the associated inaccuracies.
• Versatile Machining Capabilities: With machine X-Y-Z travels ranging significantly, this series can accommodate a variety of workpiece sizes. It’s equipped to handle intricate, detailed work as well as larger projects, offering flexibility across a range of applications.
• High-Performance Spindle: The spindle power varies from 35 hp to 50 hp, with spindle speeds ranging from 2,000 to 3,000 rpm. Equipped with two-speed gearboxes, these spindles provide the necessary torque and speed for diverse machining operations, enhancing both efficiency and quality.

You Ji HBM Series: Combining Innovative Design with High Precision

• Superior Support and Rigidity: The You Ji HBM series features a moving column for the Z axis and a moving table for the X axis, similar to the Johnford BMC. Its design provides full table support over the entire X-axis travel, leading to enhanced rigidity and precision. The triple box guideway with a hydrostatic way structure on the X axis offers advanced stability and support.
• Enhanced Precision and Durability: Precision ground and induction hardened box ways in all linear axes, complemented by hand-scraped Turcite-B coated mating surfaces, ensure prolonged machine life and sustained accuracy. The ways are force-lubricated, reducing friction and wear, while large diameter, pre-tensioned ballscrews assure precise positioning.
• Powerful and Efficient Spindle: The triple-cooled spindle motor, with a power of 60 hp and a speed of 2,500 rpm, generates impressive torque. This capability allows the machine to perform demanding drilling and milling operations with precision and ease.
• Customizable for Specific Needs: A standout feature of the You Ji HBM series is the extensive range of customization options available. From axis extenders to rotary tables and pallet changers, these machines can be tailored to meet specific production requirements, making them a versatile choice for various industrial applications.

Both the Johnford BMC and You Ji HBM series represent the pinnacle of table type boring mill design and functionality. These machines are not just tools but are precision-engineered solutions, adaptable to a wide range of industrial applications, ensuring that whatever your machining challenge, you have the right equipment to meet and exceed expectations.
