The features of the龙门mill casting: Tensile strength:≥250N/mm2Hardness:HB=190~240Castings meetHT250Chemical composition standards and mechanical property test standards. The gantry milling machine body casting is divided into two sections for casting, and can also be processed in two stages during rough machining. However, during fine machining, they can be connected together and utilize the factory's...3.2*16Overall machining of rice gate planer16Overall straightness of the rice bed body and the machining accuracy of the machine tool bed.
Casting process for the龙门mill machine frame:
One, casting blanks must not have casting defects such as sand holes, blow holes, shrinkage porosity, cracks, etc.
Two, Castings The material requires tempering treatment, commonly known as secondary tempering.
Three, carry out debris removal, ensuring that waste sand and other debris are cleaned up thoroughly.
Four Castings The surface should be coated with anti-rust paint (to be selected according to customer requirements).

The龙门mill consists of a gate frame, a bed working table, and an electrical control system.
The door frame is composed of upright posts and a top beam, with a cross beam in the middle. The cross beam can move up and down along the guide tracks of the two upright posts. The cross beam has...1～2A milling head with a vertical main spindle, capable of lateral movement along the beam guide rail. A milling head with a horizontal main spindle can also be installed on each of the two pillars, allowing for vertical movement along the pillar guide rail. These milling heads are capable of machining several surfaces simultaneously. Each milling head is equipped with a separate motor (power up to)150Kilowatts, variable speed mechanisms, control mechanisms, and main shaft components, etc.
The horizontal long bed is equipped with a movable worktable, covered with a guard. During processing, the workpiece is mounted on the worktable and moves in a longitudinal feeding motion.
The龙门mill has several variants to accommodate different processing objects.
①龙门Tapping and Milling Machine: Equipped with a milling and boring head on the beam, the main spindle (sleeve or slide rest) can perform axial机动 feeding and features a fine adjustment mechanism.,Fine-tune speed as low as5millimeters/Equipped for boring and milling operations.
②龙门Drill & Milling Machine: Equipped with a power head on the beam, drill bits or milling cutters can be mounted via rods to perform drilling and milling operations.
The龙门mill's bed is equipped withXAxial guide rail, the gantry milling machine table spans and is securely fastened to the bed. Above the table, an adjustable gantry bridge is set up, which includes: gantry bridge plate, the gantry bridge plate is movably clamped to theXOn the shaft guide rail.ZAxle guide rail, mounted on the gantry. Beam, equipped with aZAxle trolley, beam passes throughZAxle trolley, with the movable chuck engaged thereon.ZOn the shaft guide rail and the beam, additional installations are also equipped.YAxial guide rail. Machining unit,龙门milling machine machining unit,removable installation on theYOn the shaft guide rail, enabling the gantry to operate under the control of the numerical control circuit control system.X、Y、ZThree-axis 3D machining. The CNC gantry milling machine is equipped with operations such as milling, drilling, boring, and cutting.
The main parameter of gantry milling machines is the width of the worktable, and some are also measured by the gantry width.
