Product Description

1.Mainly used to drill large plate such as flange, .tube plate etc.

2. Precision spindle, high speed-drilling, also has the function of slight milling the narrow slot. 3. Direct transfer of CAD/CAM, automation and high precision can be realized.    Advanges and Features:

1.Both hard alloy innercolling high speed drilling head and high-speed steel twist drilling head are avaliable. 

2.It also has the function of milling straight groove slightly. CNC control,easy operation , automation, high precision. 

3.This machine is mainly composed of bed (worktable), gantry, vertical ram-type drilling spindle,hydraulic system, cooling system, auto-lubricating system, CNC system, electrical system and chip-conveyor, etc. 

4.Two movable slides are equipped on the cross beam of gantry. The slides are guide pairs and driven by AC servo motor and precise ball screw pair of big pitch respectively which are located between the two guideways. 

5.The slides on the cross beam are equipped with vertical CNC feeding ram-type drilling spindle, which adopts special conversion motor with heavy load for spindle.   

6.The motor drives the spindle via synchronous belt. The drilling spindle adopts Taiwan precision spindle (inner cooling) with disk spring automatic broach mechanism, hydraulic cylinder loosing cutter, very convenient to change shank.   

7.The machine is equipped with hydraulic system to finish the hydraulic balance of vertical ram and hydraulic cutter loosing of spindle. 

8.It is equipped with chain-conveyor and chip trolley. The cooling system is equipped with paper filler, high-pressure inner cooling pump and low-pressure outer-cooling pump, which are used for inner-cooling or out-cooling of cutter.
