Types, performance characteristics and safety operating procedures of gantry milling machines

Gantry milling machine is a kind of mechanical equipment that can process large workpieces on the plane and bevel. It is suitable for batch and mass production. It can also be referred to as gantry milling for short. It has a portal frame and a horizontal long bed with high machining accuracy. , And the production efficiency is also high. Among them, on the CNC gantry milling machine, some special parts can also be processed in space or curved surface, which can be described as a lot of applications. 1. The difference between the planer and the planer. The shape of the planer is similar to that of the planer. The difference is that its beam and column are not equipped with a planer tool holder but a milling tool holder with a headstock, and the longitudinal table of the planer milling machine reciprocates. It is not the main movement, but the feed movement, and the rotary movement of the milling cutter is the main movement. 2. According to whether the gantry is movable or not, the types are divided into gantry fixed workbench movable type and gantry movable type (also known as bridge type). Bridge-type gantry milling is characterized by small footprint and large bearing capacity. The gantry stroke can reach 20 meters, which is convenient for processing extra-long or extra-heavy workpieces. According to whether the beam moves on the column, it can be divided into moving beam type and fixed beam type. Two types; the beam moves on the elevated bed, which is called the elevated type. 3. Performance characteristics (1) The gantry milling machine has sufficient rigidity, high efficiency, easy operation, simple structure, comprehensive performance, etc. The specific features are as follows: (2) The end milling head is equipped with TX400 heavy gantry milling head, double Rectangular guide rail, strong rigidity. (3) The milling head is equipped with a ball screw, a pneumatic broach device, and is driven by a servo motor. (4) The side milling head is equipped with a V5 type gantry milling head, equipped with an independent lubrication device, and the lifting is driven by an ordinary reducer, and the frequency conversion speed is adjusted. (5) One-key conversion of three-axis CNC system for general milling/numerical control milling, which can be programmed and manually operated by the expansion panel, which is extremely realizable in the actual machining process. (6) The machine bed advances and retreats, the upper and lower beams, and the upper and lower end milling heads are equipped with Taiwan ball screws, which are driven by a servo motor. (7) Hand-held electronic handwheel unit, convenient for three-axis tool setting. (8) Unique cross beam lifting safety interlocking device, repeated positioning accuracy of the machine tool. (9) The Taiwan standard cycloid pump unit is continuously lubricated, and the failure rate is low. 4. Safety operation rules (1) Work objects should be clamped by pressing plates, screws or special tools. It is not allowed to use a normal wrench to add casing to avoid slipping and hurting people. (2) The tool must be clamped firmly, otherwise it is not allowed to drive to work. (3) Before work, check the operation of the transmission part of the machine tool, and install the baffle of the machine tool before it can operate. (4) When milling various workpieces, especially rough milling, slow cutting should be carried out at the beginning. (5) When moving the workbench and the tool holder, the fixing screws should be loosened first. (6) When loading and unloading knives, a copper hammer or mallet should be used to lightly hit them to prevent cutting tool fragments from flying out and hurting people. (7) During cutting, it is not allowed to change speed and adjust the tool, and it is forbidden to touch or measure the workpiece by hand. (Picture/text http://www.wxdtc.com/)
