Commodity of Main Accessories	Picture	Detail description
Machine Bed Worktable		Application: The machine bed frame is made of steel plate welded structure, and the stress is removed by tempering heat treatment, and the accuracy is stable. The bed is installed on the foundation through anchor bolts. Two linear ball guide rails with high load-bearing capacity are mounted on the plane parallel to the bed, and a high-precision ball screw is mounted on each side of the bed. A movable numerical control sliding table is installed on the guide rail slider. The longitudinal movement of the CNC sliding table is driven by two AC servo motors for longitudinal movement.
Gantry-moving frame		The gantry adopts steel plate welded structure, and the stress is removed by tempering heat treatment. The two outriggers are respectively installed on the numerical control sliding table of the bed, and move longitudinally along with the numerical control sliding table. Two ball linear guides are installed transversely in front of the cross beam of the gantry, and a precision ball screw is installed in the middle of the linear guides. The ball screw is equipped with a horizontally movable CNC slide. The CNC sliding plate drives the screw nut of the ball screw through an AC servo motor to realize lateral movement (X axis).
CNC vertical ram type drilling spindle head		On the CNC slide in front of the gantry-moving frame, there are two ball linear guides and one ball screw, on which is equipped with a ram-type power head that can move vertically. The power head is driven by the screw nut of the ball screw with a brake AC servo motor for verticalmovement (Z axis). A balancing oil cylinder is installed on both sides of the power head box to balance and stabilize the vertical movement of the power head. The ram-type power head box is made of high-quality gray iron casting, and the stress is removed by tempering heat treatment. The power head spindle adopts Taiwan key high-precision high-speed internal cooling spindle. The spindle taper hole BT50 has a butterfly spring automatic tool broaching mechanism, and a hydraulic (air) cylinder loosens the tool, making it very convenient to change the tool. With center water outlet and pneumatic chip blowing function. Spindle rotation adopts Jianchun spindle special servo motor to drive the spindle through a timing belt, 1-2.5, low speed and large torque, which can withstand heavy load drilling.
Y axis moving unit		Transmission mode: precision screw transmission. Y axis moving unit Protection measures: sheet metal cover to prevent the servo motor from dust pollution.
X axis moving unit		Transmission mode: precision screw transmission. X axis moving unit Protection measures: sheet metal cover to prevent the servo motor from dust pollution. The Y-axis of the machine is equipped with a stainless steel protective cover, and both sides of the X-axis are equipped with a flexible protective cover. Waterproof baffles are installed around the workbench.
CNC electrical cabinet		The electrical cabinet is installed at the front left of the machine. The electrical cabinet is equipped with circuit breakers, power supplies, servo transformers, control transformers, servo motor drives, spindle motor inverters, and some low-voltage electrical appliances required by the equipment. The CNC system of this machine tool is made by YOKOGAWA, with electronic handwheel, which is powerful and easy to operate. Equipped with a portable computer and RS232 interface. With processing preview and review functions, the operation interface has man-machine dialogue, error compensation, automatic alarm functions, and can realize CAD/CAM automatic programming.
Hydraulic System		This machine is equipped with a hydraulic system to complete the hydraulic balance of the vertical ram and the hydraulic tool loosening of the spindle. (And choose hydraulic clamping manipulator according to customer requirements)
