Vertical axis table plane grinding machine is a series of benzene, which is suitable for grinding various parts (such as bearing rings, piston rings, connecting rods and grinding tools, etc.) in batch production workshops of machine manufacturing industry. The accuracy should meet the requirements of BT9909.2. The machine tool is of grade 1 accuracy of JBT9871 standard.
The machine tool has the following structural features:
) The grinding head has motorized and manual lifting, and vertical micro-disk feeding can be provided according to needs: b) The worktable is divided into movable and non-movable types, and the movable one should have motorized positioning function: c) The rotation of the worktable is motorized:
d) The column [or grinding head] has vertical adjustment machine e) The electric suction cup has good retraction function:
f) The cooling and purification device are provided.
4.2 Semi-automatic vertical spindle slow table surface grinder
The machine is suitable for mass production of various parts in the machinery manufacturing industry. The precision should meet the requirements of JB/T9909.2. The machine tool should have the V-level precision of JB/T9871. In addition to the structural features of the basic series, the machine tool should have the following structural features: a) It has a semi-automatic grinding cycle control system and a good interlocking device, b) It has an automatic size control mechanism, bzxZ.net
4.3 Vertical polishing machine
The machine tool is used for grinding the surfaces of various parts in the production workshop of the manufacturing industry, which can save the process of grinding and polishing. It can be finished from the roughing step. The precision should meet the requirements of JB/T9909.2. The machine tool is of the grade precision specified in JB/T9871.
