Bed-type milling machines are a common and important machine tool with many features and advantages. Especially in the processing of large work piece is important role, its versatility and ease of operation is a significant advantage. It is widely used in many fields such as machinery manufacturing, mould manufacturing, automobile manufacturing, etc. It can meet a variety of processing needs and provide reliable support for industrial production.
Bed-type milling machine is a kind of milling machine that the table does not lift, compared with the ordinary milling machine, there are mainly the following differences:：
| Main differences | Bed-type milling machines | General milling machines |
| Structural stability | The bed structure is sturdy and the overall stability is outstanding. The main components such as base, body, table, centre slide are usually made of high-strength material casting and treated by artificial aging to ensure the stability of long-term use. | Relatively simple structure, slightly less stable, may affect the effect due to vibration when processing high-precision complex work pieces. |
| Load-bearing capacity | High load-bearing capacity to handle heavy and large-sized work pieces | Limited load capacity, suitable for small to medium sized and heavy work-pieces |
| Processing precision | Stable structure and good rigidity, can achieve higher machining accuracy, suitable for high-precision parts machining. | Relatively low precision, suitable for general machining where precision is not particularly demanding |
| Price and cost | High manufacturing cost and expensive | Lower cost and relatively affordable |
| Scope of application | Suitable for large work-pieces, high-precision machining and mass production. | Suitable for small, simple parts machining and single piece or small batch production. |
In addition, bed milling machines have the following advantages:
1: The vertical movement of the machine is realized by means of a spindle box mounted on the column, which improves the rigidity of the machine and facilitates the use of larger cutting loads;
2: Structurally, the table has two types: round and rectangular; the whole is bed-type structure, the milling head is mostly high-power mechanical speed-adjustable high-precision milling head, which can work in a certain range, the feed of the spindle sleeve has the functions of automatic, manual, manual fine-tuning, etc., and the rigidity of the spindle is large, and it’s easy and flexible to adjust the speed;
3: The spindle box can be lifted up and down manually and motorized to complete the motorized feeding and rapid movement, which is more convenient and quicker to operate;
4: The longitudinal and transverse direction on the bed generally has three kinds of manual feeding, motorized feeding and motorized fast feeding, which can meet different processing requirements, and fast feeding can shorten the non-processing time;
5: The guide rails of the table are mostly wide rectangular guide rails, and the guide rails in X, Y and Z directions are quenched by ultra-audio quenching, precision grinding and scraping, which, together with the forced lubrication, can reduce the low-speed crawling, improve the accuracy and prolong the service life of the machine tool;
6: The lubrication device can carry out forced lubrication for the longitudinal, transverse and vertical screws and guide rails to reduce the wear and tear of the machine tool and ensure the efficient operation of the machine tool, and the cooling system can adjust the size of the flow of the coolant to meet the needs of different machining.
This kind of machine tool is commonly used for processing medium-sized parts with various functions such as milling, drilling, tapping, reaming and reaming, etc. It is an ideal processing equipment for machinery, electronics, instruments, meters, mould, automobiles and other industries.
