Johnford and You Ji boring mills are heavy duty machines built tough like a horizontal boring mill should be. These boring mills are made of heavy Meehanite iron castings and can be custom made to order to accommodate the largest of parts. Heavy duty comes in the form of heavy castings, big box ways, and high horsepower gear driven spindles that generate earth shaking torque. Read More
Both Johnford and You Ji boring mills are a moving column design in the Z axis and moving table in the X axis. This design, as opposed to a fixed column / moving table design, offers superior performance, operator accessibility, and excellent chip disposal. The moving column, with the table moving in X only, allows the table to be fully supported at all times over the base allowing for best accuracy and high table load capacities. Available in 4.33”, 5.1”, and 6.3” bar diameters and a variety of travels, we have a boring mill to fit virtually any requirement.
These horizontal boring machines are equipped, not stripped. Standard features include 60 position tool changers, high pressure coolant through the spindle, linear scale feedback, tall table and operator guarding for superior chip and coolant containment, and full B axis rotary tables with scale feedback. The You Ji boring mills feature a hydrostatic B axis with dual pinion drive for unprecedented accuracy and load carrying ability. With scale feedback in both the linear and rotary axes, these machines meet the highest accuracy requirements. Fanuc CNC controls are standard equipment for these boring mills, with Siemens, Heidenhain, and Mitsubishi controls offered optionally.
Not only are these great machines, but they are great values as well. All of these outstanding standard features come with a great package price. Contact us today to get a quote on the best value in CNC machine tools!
Recent Boring Mill Installation from Absolute Machine Tools
This NEW Johnford BMC-130 horizontal boring mill was recently installed at Grand Bahama Shipyards Limited, in Freeport, Grand Bahama. The Johnford BMC-130 boring mill will be used to re-machine and recondition the mounting and sealing surfaces of the pitch-able propeller blades on both main thrusters and bow thruster.
