Revolutionary Special-Shaped Punch Grinding Solution: Five-Axis CNC Grinding Machine
In the mold manufacturing and precision machining industry, the processing of special-shaped punches has long faced unique challenges: a wide variety of models, small production batches, and high processing frequency. Traditional machining methods often struggle to balance efficiency and flexibility, leading to high production costs and extended delivery cycles. To address this industry pain point, we have developed an innovative automated grinding solution for special-shaped punches. Based on a five-axis CNC grinding machine platform, it achieves a perfect combination of

Optimization method for high temperature of bearing type spindle
The cause of high temperature is usually not a single factor, but the result of multiple factors interacting with each other. We can systematically analyze from the aspects of lubrication, assembly, load, cooling, and the components themselves. 1、 Lubrication system issues (most common causes) Improper selection of lubricating oil: Viscosity mismatch: The viscosity of the oil is too high, resulting in increased internal friction resistance and excessive heat generation; The viscosity is too low to form a sufficiently strong oil
