JB/T4289.41999
The mobile workbench vertical precision bed is the basic series. It is suitable for fine boring of cylinder bores and cylinder liner holes in general batch internal combustion engine manufacturing and internal combustion engine repair industries, as well as fine boring of holes in oil cylinders, cylinders and other bore parts in other machine manufacturing departments. The accuracy should comply with the provisions of JBT4289.1.
The machine tool should have the following structural features: the spindle head is mounted on the carriage, and along with the carriage, it performs vertical feed or fast forward and reverse motion on the column. The spindle performs rotational motion in the rigid spindle shell. The spindle head Can be replaced. The workbench can be manually adjusted vertically and horizontally on the base. When the workbench needs to be moved frequently, a motorized rapid movement mechanism can be added to the workbench. 4.2 The vertical precision machine with fixed-week table
machine tool is suitable for precision boring of parts such as cylinder liners, single-cylinder blocks, oil cylinders, and cylinders during mass production. The accuracy should comply with the requirements of Door B 4289.1.
This type of machine tool is based on the ordinary vertical fine boring machine and changes the movable workbench into a fixed workbench. This kind of machine tool has the advantages of simple structure, strong rigidity, high precision and good precision retention. 4.3 Fixed table pin chain vertical fine boring machine
This kind of machine tool uses a multi-edge boring reamer, so the tool durability is improved, the feed amount is increased, and the production efficiency is greatly improved. The machine tool is suitable for finishing holes in professional factories that mass-produce cylinder liners, hydraulic cylinders, cylinders, etc. The accuracy should comply with the relevant standards. This type of machine tool is based on a fixed-table vertical finishing machine. It increases the power of the main motor, appropriately reduces the spindle speed, increases the amount of tool feed, and changes the spindle structure to adapt to the installation of multi-edge boring and comparing tools, which is better than fixed work. The vertical fine boring machine has higher production efficiency. 4.4 Multi-station vertical finishing machine
machine tool is suitable for precision drilling in mass production enterprises. The accuracy should meet the requirements of relevant standards. This type of machine tool is based on the vertical fine boring machine and replaces the mobile worktable with a multi-station workbench. According to the user's ordering requirements, the multi-station workbench can be a rotary type or a multi-station workbench. It is linear moving type. The number of stations can be two or more. This type of machine tool can process at one station while loading and unloading workpieces at another station during use, which has high productivity. 4.5 Multi-station mirror hinge vertical precision chain machine
machine tool is suitable for finishing holes in professional T factories that produce cylinder liners, hydraulic cylinders, cylinders, etc. in large quantities. The accuracy should meet the requirements of relevant standards.
This type of machine tool is based on a multi-station vertical fine boring machine. It increases the power of the main motor, appropriately reduces the spindle speed, increases the amount of tool feed, and changes the spindle structure to adapt to the installation of multi-edge clock hinges. Knife processing has higher production efficiency than multi-station vertical finishing machines. 4.6 Multi-axis vertical finishing machine
This kind of machine tool can boring two or more holes at the same time in one working cycle, and is suitable for use in T factories that produce cylinder blocks or cylinder liners in large quantities. The accuracy should comply with the relevant standards. . The machine tool should have the following structural characteristics:
a) The slide moves on its guide rail, and 2 or more boring heads are installed on the slide; b) Generally has a fixed T. worktable; ||tt| |c) According to user needs, the spindle axis can be perpendicular to the horizontal plane (called an upright type), or at a certain angle with the horizontal plane (called an oblique type):
d) Generally, it has a semi-automatic Work cycle.
