Double spindles high speed CNC drilling machine for flange
1. Applicable Industry:
Mainly used in the drilling processing of the round pieces such as, flanges, plate, tube steel… Replacing the man-made and the drill plate making and drilling. Improving the product precision and the productivity of labor. Reduced the period of production arrangements to be suitable of quantity production.
2. Feature: 2.1 The main frame of the box type or approximate box type structure, made of high strength welded after thermal aging full (high temperature of 550 DEG C and the insulation is not less than 4 hours) can effectively eliminate the residual stress, so the dynamic and static rigidity is good, high stability, deformation is very small.
2.2 The main drilling spindle adopts 7.5kW strong overload spindle frequency conversion motor drive, low speed torque, heavy load can be carried out, drilling strong and powerful, drilling stability is good.
2.3 The machine adopts two sets of SIEMENS system, and is equipped with the corresponding MAXSINE servo motor and servo driver. It has good compatibility, powerful function and easy operation
2.4 The spindle box is made of TH
250 material. High strength, high stability, wearable and difficult to deform. The utility model has the advantages of high rotary precision, high machining precision, simple transmission, no mechanical wear, good vibration absorption, etc.
2.5 The main transmission parts, such as linear ball guide, precision ball screws, etc., are of high installation accuracy. For example, linear guide installation datum, after fastening with 0.04mm feeler gauge inspection, do not insert; the difference between the linear guide 0.05/1000mm; ball screw and linear guide parallelism tolerance 0.03/1000m.
2.6 Hydraulic three claws self centering chuck, automatic clamping round flange, without manual centering, repeated centering, high accuracy, greatly improve the processing efficiency.
