Product Description

High Speed RCQ2280 Large-diameter Heavy Parts Deep Hole Drilling And Boring Machine

 

RCQ2180/RCQ2280 deep hole drilling and boring machine
Machine tool application: It can complete the drilling, boring and nesting of large-diameter heavy parts. Processing technology: The workpiece rotates at low speed during processing, and the tool rotates and feeds at high speed. When drilling, the technology of chip removal in BTA is adopted, and when boring, the cutting fluid in the boring bar is used to discharge cutting fluid forward (the head end of the bed), and the technology of chip removal. The nesting adopts the process of external chip removal, and needs to be equipped with special nesting tools, tool holders and special fixtures. According to the needs of processing, the machine tool is equipped with a drill (boring) bar box, and the tool can be rotated and fed.

Machine use:
♦It can complete the drilling, boring and nesting of large diameter heavy parts and deep holes.

Processing technology:
♦ During processing, the workpiece rotates at low speed, and the tool rotates and feeds at high speed.
♦When drilling, the technology of chip removal in BTA is adopted.
♦When boring a hole, the cutting fluid in the boring bar is supplied to the front (the head end of the bed) to discharge the cutting fluid and chips. ♦The nesting adopts the process of external chip removal, and needs to be equipped with special nesting tools, tool holders and special fixtures.
♦ According to the needs of processing, the machine tool is equipped with a drill (boring) bar box, and the tool can be rotated and fed.

Machine main parts: Machine bed , headstock, oil pressure head, one set drill bar support rest, sliding guide rail, rack and pinion, coolant system, DELTA PLC control system, electric cabinet, one set center rest and so on . Workpiece clamping One end of the workpiece is clamped by the manual three-jaw chuck of headstock , oil pressure head tighten another end automatically(workpiece OD chamfer 4X30°), center rest support the workpiece . The gears are machined by precision grinding , gear surface is quenched by high frequency quenching, and the hardness of the tooth surface is HRC48-52, so that the gear can obtain high strength, high hardness, high wear resistance and high fatigue limit, and can withstand relatively large alternating load and shock load. In order to improve the service life of gears and bearings, lubricating oil is used to circulate lubrication.
