Deep Hole Drilling Machine Overview
Gun drilling machines are mainly for drilling deep hole of small diameters (∅0.7mm ~ ∅40mm). This type of machines use gun drill as cutting tool. And the most common machines for precise deep hole processing.
Widely used in industries like auto parts, machinery, textile, etc. Satisfy drilling most types of parts like shaft, box, non-standard, etc.
BTA Deep Hole Drilling Machines
BTA machines are mainly for drilling deep hole of big diameters (≥∅16mm) and large length-to-diameter ratio (Max.ratio can be 400:1).
Besides, BTA’s processing efficiency is about 2-4 times higher than gun drilling. So, it is an ideal deep hole drilling machine for batch production, high drilling efficiency requirement and continuous working situation.
GSM produces ZK21D BTA machine. Realizes drilling and boring. The max. drilling depth reaches 4000mm.
Design & Configuration

Counting function for effective drill tool sharpening to remain precision and prolong tool’s life.
Step-less rotating and feeding.High speed precise mechanical spindle, spindle motor, frequency motor and motorized spindle driving for option.
High pressure rotary joint inserts cutting fluid into drilling tool from back of spindle. Introduced DEBULIN from USA and ROTOFLUX from Italy for option.
Introduced linear guide and ball screw of high rigidity and precision.
Ensures efficient, precise and stable drilling.
Lubricated by automatic batch lubrication pump.
Auxiliary Chip Flushing Device
On side of chip box.
Manual and automatic control.
Efficiently help to remove chips.
Drilling Tube Support
Driven by chains.
When tool returns keeping the structure on average position.
Help to conveniently replace tools.
Adjustable Drill Driver Structure
Gun drilling tool’s length changed after grinding. Keep uniformity of tool’s length by setting gauge and adjustable shank.
This ensures uniformity of drilling depth of multiple spindle machines.
