FEATURE AND APPLICATION
The grinder has become a kind of successful universal cylindrical grinder after a long term running and continuously improving design. It is used for grinding external and internal cylindrical and conical of work pieces. The machine is noted for its high rigidity and precision. Under common condition, the geometric precision is up to IT6-IT5 and stable. As a result of simple operation, high power, wide and stable function, the grinder is designed for various kinds of batch process. Spindle systems of headstock, tailstock and wheelstock have the good structural property, large carrying capacity and the strong rigidity. The rate of stepless speed regulation can be changed within 320r/min. It makes you very pleased to select the best surface rounghness and the highest cutting efficiency. Worktable is steplessly driven by hydraulics, and it can be adjusted stably at the range of 0.1 – 4m/min. It features grinding of short distance and high frequency, and front and back precision is high. The operation of hydraulic system is very convenient, neither lashing in high speed nor creeping in low speed. The transverse feed of wheel has two sets of devices, that is automatic periodic and manual micro-feed. It guarantees to obtain accurate and dependable feed. The machine is equipped with many kinds of attachments, such as wheels, dogs, coolant tank, and wearing parts, and complete set of usable tool. |
