How much does Hebei gantry machining center cost?

The gantry milling machine consists of columns and top beams forming a portal structure. The cross beam can move up and down along the two column guide rails. There are 1 to 2 milling heads with straight spindles on the beam, which can move laterally along the beam guide rail.

The rake angle of the face milling cutter used for gantry milling is generally small. For materials with higher milling strength and hardness, a negative rake angle can be used. The value should be selected based on the workpiece material and tool material. For example, if carbide tools are used, milling steel: -150～150; Milling cast iron: -50～50; Milling bronze and brass: 40～60; Milling aluminum alloy: 150, etc. The main deflection angle κr is selected in the range of 450 to 900. When milling cast iron, κr=450 is used. When milling general steel, κr=750 is often used. When milling flat or thin-walled parts with convex shoulders, κr=900 is used. Operating procedures for gantry milling machines: The tooling clamps must be strong, the pressure plate and pads must be stable, and pay attention to the width of the gantry. After the workpiece is clamped, run the machine slowly to check whether the workpiece and fixture can pass safely. Before officially driving, the position of the travel stopper must be adjusted appropriately and firmly, and the debris on the table must be removed. It is prohibited to put your head or hands into the front of the gantry and milling cutter after driving. It is forbidden to stand on the table, and it is even forbidden to step across the table. No one is allowed to pass within the guardrails at both ends. When multiple people operate, one person must direct the operation, and the movements must be coordinated and coordinated. Choose a safe place when loading, unloading, and turning workpieces; pay attention to sharp edges and burrs; work closely with the operator and hooker. After driving, if you want to readjust the stroke stopper, measure the workpiece, or clean the iron filings, you must stop the car. ​​

The overall structure of the machine tool is a fixed workbench, beams, and a movable gantry. The main structural parts are made of high-strength cast iron and resin sand molding, which have excellent shock absorption and thermal stability. The whole machine has a structural design with high rigidity and high reliability. It is suitable for processing heavy-duty and super-heavy basic parts in metallurgy, railways, heavy machinery, shipbuilding, power generation, automobiles, aerospace, printing, molds and other industries, especially various flat surfaces, curved surfaces, etc. where the parts themselves are heavy and the length of the workpiece is long. CNC machining of spatial surfaces and holes. It is widely used in the roughing and finishing of various complex parts such as plates, boxes, frames, etc. in the machinery manufacturing industry. It can complete three-axis linkage curved surface processing and rigid tapping, and can add accessory milling heads according to customer processing technology requirements. According to the processing technology of the workpiece, pentahedral processing can be completed in one clamping. The spindle of the boring and milling head is driven by a communication spindle servo motor, and the output end of the spindle servo motor is directly connected to the automatic two-stage concave and convex gear transmission.

Milling method of gantry machining center

Most of the milling on the gantry machining center is done using the up-milling method. However, down milling should be used as much as possible, which will achieve better processing results. When the gantry machining center is up-milled, fierce conflict occurs before the blade cuts in, causing the machined surface to harden, making it difficult for the next cutter tooth to cut in. ​
When the gantry milling machine is down milling, the milling width should be approximately equal to 2/3 of the milling cutter diameter. This ensures that the cutting edge can immediately cut into the workpiece as soon as it starts, with almost no friction. If it is less than 1/2 of the milling cutter diameter, the blade begins to "collide" with the workpiece again. Since the cutting thickness becomes smaller when cutting in, the feed per tooth will also be reduced due to the narrowing of the radial cutting width. The result of "friction" shortens the tool life. For carbide tools, it is more beneficial to increase the feed per tooth and reduce the depth of cut. ​
Therefore, during rough milling, if the radial cutting width is smaller than the milling cutter radius, increasing the tool feed will increase the tool life and shorten the gantry milling machine processing time. Of course, fine milling requires a smooth surface on the workpiece, so the amount of tool passes should be limited. Trial adjustment of this radial milling width and confirmation of the ratio of milling cutter diameter to radial milling width are performed on a high-precision gantry machining center so that changes in the surface roughness of the workpiece can be observed while adjusting the ratio.
