Video of heavy duty cnc plate drilling machine
The machine bed and worktable are made of high-quality gray iron (HT300). After two tempering and heat treatment to remove stress, it has high strength and is not easy to deform. The independent form of the bed and the worktable eliminates the resonance generated in the drilling process and prolongs the service life of the alloy drill bit.
The moving gantry adopts the different-surface structure of the guide rail, and the stress is removed by two tempering heat treatment. The two left and right outriggers of the gantry are mounted on the column slides of the two beds. Two sets of large inertia AC servo motors on the left and right beds synchronously drive two precision ball screw pairs to drive the CNC sliding table and the gantry to move longitudinally. Two sets of linear guide rail pair guides on the left and right bed bodies ensure high positioning accuracy and repeatable positioning accuracy.
The ram-type power head with vertical CNC feed, its vertical slide table and power head ram are all cast with high-quality gray iron (HT300). Four-rail arrangement is adopted. The force is more stable. The spindle motor of the power head adopts a dedicated servo motor for the spindle to drive the spindle through a synchronous belt, with large torque at low speed, which can not only bear heavy cutting load, but also be suitable for high-speed machining of cemented carbide tools. All-in-one drilling, tapping and milling. Equipped with a spindle torque detection sensor, by setting the cutting torque value, the equipment can automatically stop drilling when the tool is severely worn or chipped, preventing further drilling and preventing the appearance of unqualified holes.
The power head spindle adopts Taiwan precision spindle, the spindle taper hole BT50, which can be clamped with carbide inner coolant drill bit and high-speed steel twist drill bit, and has the function of purging and cleaning the spindle taper hole.
