5.31 Inch Spindle CNC Horizontal Boring Mill

The FEMCO BMC-135TN and BMC-135TNL both support a table load capacity of 33,000 lbs via their Full B-Axis Rotary Table. The broader FEMCO BMC series can accommodate up to 40,000 lbs depending on the model, making them suitable for machining very large and heavy weldments and structural components.

All FEMCO horizontal boring mills in this category are equipped with FANUC CNC control systems. Depending on the model, control options include FANUC OiMF, FANUC 31i-B, and FANUC AI Contour Control (AICC). These advanced controls support high-precision contouring, multi-axis coordination, and efficient program management for complex machining operations.

The FEMCO BMC-135TNL offers the largest X-axis travel in this category at 157.4 inches (3,998 mm), making it ideal for machining very long weldments and large structural components. The BMC-135TN provides up to 118 inches of X-axis travel, while other BMC series models range from 55.12 to 157.4 inches depending on configuration.

The FEMCO BMC-135TN and BMC-135TNL are equipped with a 60-tool Automatic Tool Changer (ATC). This large tool magazine allows operators to run complex multi-operation machining cycles — including boring, milling, drilling, and threading — without manual tool changes, significantly reducing cycle time and improving throughput.

These machines are capable of precision milling, coordinate drilling, boring, reaming, tapping, and threading. The 5.31-inch spindle diameter and 50 HP geared head spindle support heavy-duty cutting operations on large and complex workpieces such as welded frames, structural components, housings, and machine bases up to 20 tons.

Yes, both the FEMCO BMC-135TN and BMC-135TNL include through-spindle coolant as standard. This feature delivers coolant directly to the cutting zone, improving chip evacuation, extending tool life, and enabling higher cutting speeds — particularly beneficial during deep-bore drilling and long-reach operations on hard or tough materials.
