T2110G Deep Hole Drilling and Boring Machine

T2110G DEEP HOLE DRILLING AND BORING MACHINE

Machine tool usage: This machine tool is a special machine tool for processing cylindrical deep-hole parts. It is suitable for drilling and boring cylindrical deep-hole workpieces. When boring, oil is supplied by an oiler, and chips are discharged to the head of the bed through the cutting zone. The chip bucket. When drilling, the internal chip removal method (BTA) is used, that is, the oil feeder supplies oil, and the chips are discharged from the inside of the drill pipe to the chip removal bucket at the back of the bed through the cutting zone.

The machine tool adopts PLC control, the tightening of the oil applicator and the reciprocating movement of the feed carriage are controlled by servo motors, and the transmission adopts the rack drive in the middle of the two guide rails, which ensures the accuracy and rigidity of the feed drive in the ultra-long motion. . Protection is installed on both sides of the bed body, and the above-ground fuel tank structure is adopted to improve the environment of the machine tool. The machine tool can be equipped with manual expansion and contraction high-efficiency tools, which greatly improves the processing efficiency of the machine tool.

Deep hole machine realative technolog:

(1) Horizontal deep hole drilling and boring machine: It is the most widely used boring machine. It is mainly for hole processing, the boring accuracy can reach IT7, and the surface roughness Ra value is 1.6-0.8um. The main parameter of the horizontal boring machine is the spindle diameter.   

(2)  Coordinate deep hole drilling and boring machine: Coordinate boring machine is a kind of high-precision machine tool. Its structural feature is a precision measuring device with coordinate positions. The coordinate boring machine can be divided into single-column coordinate boring machine, double-column coordinate boring machine and horizontal coordinate boring machine. 

Single-column coordinate boring machine: The spindle drives the tool to make the main rotation movement, and the spindle sleeve makes the feed movement in the axial direction. Features: Simple structure, convenient operation, especially suitable for processing precision holes of plate-shaped parts, but its rigidity is poor, so this structure is only suitable for small and medium-sized coordinate boring machines. Double-column coordinate boring machine: The tool is installed on the main shaft for main movement, and the workpiece is installed on the worktable to move longitudinally and linearly along the bed guide rail. It has good rigidity, and currently large-scale jig boring machines adopt this structure. The main parameter of the double-column coordinate boring machine is the width of the worktable. Horizontal coordinate boring machine: The worktable can rotate in the horizontal plane, and the feed movement can be realized by the longitudinal movement of the worktable or the axial movement of the spindle. Its machining accuracy is high.  

3) Diamond boring machine: It is characterized by small feed rate and high cutting speed for processing, so the processed workpiece has high dimensional accuracy (IT6), and the surface roughness can reach 0.2 microns
