ZSK2108F Gun Drilling And BTA Combined Machine
This deep-hole drilling machine supports two methods: gun drilling (external chip removal) for diameters of Ø5–30mm and BTA drilling (internal chip removal) for diameters of Ø25–80mm. It also offers a boring range of Ø20–120mm and a maximum machining depth of 2000mm. The machine is equipped with a GSK CNC system.
Description
Spindle System:Utilizes a single spindle shared by both gun drill and BTA methods. A 22kW main servo motor provides stepless speed regulation, delivering a maximum spindle speed of 2500 rpm. Switching between processes requires manual tool/accessory changeover and oil circuit adjustment.
Z-axis:Designed for 2000mm depth. It features double rectangular slideways (surface-hardened to HRC 48-52) and is driven by a servo motor via a reducer and ball screw.
Guide Frame:A fixed, shared component for both methods. It facilitates chip removal during gun drilling and oil supply during BTA drilling.
Headstock:Powered by a standard motor driving the spindle at a fixed 20 rpm through a reduction mechanism. It can be manually positioned along the bed to accommodate varying workpiece lengths and locked in place. A hydraulic system controls the axial movement of its spindle for workpiece positioning and clamping.
Tool Support:Includes two drill bar holder sets.
Cooling & Filtration System:Comprises dirty/clean oil tanks, a chain-type chip conveyor, paper bag filtration, one variable-frequency pump set, and one fixed-displacement pump set.
Structure:Foundation components such as the bed and boxes are made of high-quality stress-relieved cast iron.
