More than 60 diversified grinding machines are available in this workshop.

The internal cylindrical grinder can process the components of high-pressure air hammer with precision ranging from 0.05um to 0.01um. It has a high degree of automation.

The external cylindrical grinder can work on the DTH hammer with a roughness of 0.8um and precision ranging from 10um to 25um.

External cylindrical grinding with a precision of 0.12um

Both the lathes and drilling machines in this workshop are used to handle the components of air picks and high-pressure air hammers. They can perform a wide variety of roughing and finishing operations such as drilling, groove milling, gear milling and rough turning etc.

Test standard: Pressure: 0.5-2.1MPa, Frequency: 13-24.5Hz, Air consumption: 5m³/min-10m³/min

This high-precision vertical drilling machine is basically used to drill holes in the drill bit.
