NZG-31 Rail Drilling Machine NZG-31 rail drilling machine is compact in structure, and it is the lightest drilling machine in China at present. The rail clamping device has self-locking function, accurate positioning and high drilling accuracy. The n-tailed hollow drill bit can be used to clamp the special twist drill with n-tailed shank under 13.5 according to the needs. It has the function of automatic water supply when drilling. It is a necessary tool for maintenance, rush repair and overhaul operation of Public Works Department. Advantage 1. The water supply at the back of the main shaft is adopted to prevent the cooling water from entering the bearing and reducer, so as to improve the service life of the equipment. 2. When drilling, the rotary resistance is reduced and the drilling torque is increased. 3. The drilling time is shortened and the production efficiency is improved.
concrete sleeper bolt drilling machine The NLQ-45 concrete sleeper bolt drilling machine is suitable for drilling various types of concrete sleeper bolts under the condition of blocking the line. The principle of the nesting knife can be used to drill any position on the concrete sleeper. At the same time, the bolts can be Re-anchor the sleeper bolts in the drilled holes.

Excavator:
Polycrystalline Diamond Compact(PDC) is sintered with diamond and WC under ultrahigh pressure and temperature. Combining with the advantages of diamond and WC, PDC is with extremely high wear resistance and excellent impact strength. It is widely used in drilling for all sorts of geological terrane. Such as oil,geological and engineering drilling, etc.
TSP is unsupported polycrystalline diamond. It is with extremely high wear resistance and thermal stability(up to 1200) and high density structure. TSP is widely used in making drilling bits for petroleum and geology prospecting, and tools for diamond and machinery processing. Different shapes( cylinder, conical, square, triangle and hetrerotypic etc. ) can be offered.
