Hollow anchor bar means a rod that transfers the structures or geotechnical load to a stable rock formations, anchor bolt consists of rod, drill bit, coupling, plate, grouting stopper and nut. Widely used as an efficient anchoring means, in tunnel pre-support, slope, coast, mine, water conservancy projects, building foundation, roadbed reinforcement and geological diseases treatment such as landslip, crack, sink age. It`s irreplaceable in narrow construction environment. Hollow anchor bar is made of seamless tube with high strength.

The main structural performance and characteristics 1, machine tool main components: bed, table, beam, left and right columns, connecting beams, the top of the gantry are resin sand molding, high-quality high-alloy wear-resistant cast iron, heat aging treatment of a vibration effect of a Roughing a vibration aging treatment of a finishing, completely eliminate the negative stress of the machine to maintain the performance of the machine.
2. The bed and workbench guide rail adopt static pressure relief and wear-resistant coating technology to ensure low-speed stability and precision retention.
3, the machine tool three-way feed and milling head feed adopts separate drive mode, so that each component can run independently and improve work efficiency.
4. The ram-type boring and milling head spindle automatically shifts, the feed adopts the ball screw auxiliary transmission, and uses the hydraulic balance cylinder device to balance the weight of the ram.
5, according to user requirements can provide a variety of accessories milling head, and further expand the scope of use.
6. The electromechanical control system adopts PLC and digital AC servo control technology to achieve high precision and high reliability control.
7. The three-way feed of the machine tool adopts the international advanced level of AC variable frequency vector control to achieve stepless speed regulation.
8. The worktable is set as a touch screen setting and the worktable is operated as a hanging button station, which is accurate and convenient.
What you need to know about the structural features of the planer
The reciprocating motion of the planer work bench is the main movement, and the tool rest moves into the feed motion. The tool holder on the cross beam can make horizontal feed movement on the cross beam guide rail to plan the horizontal plane of the workpiece; the side tool post on the vertical post can make vertical feed movement along the guide rail of the column to plan the vertical plane. The knife holder can also be deflected at an angle to plan the bevel. The beam can be raised and lowered along the column guide to adjust the relative position of the tool and the workpiece. Planer planer is mainly used for processing planes or grooves on large parts, or processing multiple medium-sized parts at the same time, especially suitable for processing of narrow and long planes. The workpiece on the planer is usually pressed with a platen bolt. In the planer, there is a complex set of electrical equipment and route system. The movement of the table can be stepless.
