What process specifications should be met when operating in Xinxiang Longmen
采用面铣刀的前角一般较小，铣削强度和硬度较高的材料进还可用负前角，其数值应根据工件材料和刀具材料来选择，如选用硬质合金刀具，铣削钢：-150-150；铣削铸铁：-50-50；铣削青铜、黄铜：40-60；铣削铝合金：150等。 Gantry external processing manufacturers usually first use face milling cutters with smaller rake angles. For materials with higher milling strength and hardness, negative rake angles can be used. The value should be selected according to the workpiece material and tool material. , Milling steel: -150-150; Milling cast iron: -50-50; Milling bronze and brass: 40-60; Milling aluminum alloy: 150 and so on.
The main deflection angle κr is selected in the range of 450-900. For gantry milling , κr = 450 is used when milling cast iron for external processing , κr = 750 is often used for milling general steel, and κr = 900 is used for milling flat or thin-walled parts with shoulders.
Operating procedures: The clamps must be firm, the pressure plate and the horn must be stable, and pay attention to the width of the gantry. After the workpiece is clamped, drive a slow motion to check whether the workpiece and the clamp can pass safely. And remove the debris on the table.
严禁有人在两头护栏内通过，多人操作时需由一人指挥，动作配合要协调。 After driving, it is strictly forbidden to put your head and hands into the front of the gantry and the milling cutter, and you are not allowed to stand on the table, nor to cross the table. The gantry external processing manufacturers are strictly forbidden to pass through the guard rails on both ends. Cooperate to coordinate.
提醒要注意锐边毛刺割手，应和行车工、挂钩工密切配合，开车后若要重新调节行程挡铁、测量工件、清扫铁屑，都必须停车。 Select a safe place for loading, unloading, turning, and turning of the workpiece. The gantry external processing manufacturer reminds you to pay attention to sharp-edged burr cutters. It should work closely with the driver and hooker. If you want to readjust the stroke stopper, measure the workpiece, and clean the iron debris after driving, Must stop.
