Multi-function Deep Hole Drilling & Pull Push Boring Machine For Hydraulic Cylinder Large Shaft Processing

Superior Machine Structure & Rigidity Advantage

Ultra-rigid machine bed The whole bed adopts high-strength HT300 resin sand cast iron, after normalization and secondary aging treatment to eliminate internal casting stress permanently. Split bed body locked by high-strength bolts and taper positioning pins, equipped with double rectangular medium-frequency quenched guide rails with wide bearing surface, anti-deformation, high wear resistance and long precision retention service life. The inclined precision quenched rack is installed on the bed for stable heavy feed movement.

Stable headstock & powerful spindle system Headstock is directly mounted on bed without high spacer block, equipped with manual 3-speed shifting plus stepless speed regulation, driven by high-power 45KW servo spindle motor via timing belt and precision gearbox. All gears are precision ground and high-frequency quenched to bear heavy alternating cutting load. Spindle speed range 40-1000r/min, speed control accuracy ±1RPM, front metric 140 taper hole matched with manual four-jaw chuck for stable clamping large workpieces. Independent external circulation lubrication system ensures continuous low-temperature operation of gears and bearings.

Independent drill box with reliable cutting power Separate drill box installed on feeding carriage, also adopts 3-speed manual shift + stepless speed regulation, driven by servo motor through belt pulley gear set. Spindle left side installs tool connecting sleeve for clamping drill/boring bars; right side equips special chip hopper for smooth chip discharge. Low liquid level alarm device is built in drill box lubrication oil tank to avoid dry burning damage.

Complete multi-set support system for long workpieces Equipped with multiple sets of supporting rests to prevent workpiece bending and vibration during 13m ultra-long processing:

4 sets ring type center rest, support range Φ65~Φ360mm

Multiple sets closed fixed center rest for Φ90~Φ500mm workpieces

Independent boring bar support rest with automatic reset hanging mechanism, effectively absorb cutting shock and eliminate tool chatter when processing 13m extra deep holes. V-type workpiece pre-support bracket with T-screw manual lifting for convenient workpiece loading.

Servo Feed & High Precision Control System

Two independent servo controlled axes realize separated motion control: Z1 axis drives drill box feed movement, Z2 axis controls oil pressure feeder travel. Both axes adopt precision rack and pinion transmission with automatic backlash elimination structure, repeat positioning accuracy up to ±0.05mm per 1000mm. Full automatic centralized lubrication system regularly oils guide rails and racks to reduce abrasion and maintain long-term precision.

Dual Automatic Chip Removal & Large Flow Cooling System

Two independent chip discharge channels designed for different processing crafts:

During solid drilling: metal chips discharge backward through spindle tail chip hopper into automatic chip conveyor

During pull/push boring: chips flow out from headstock side chip tank Equipped with 8000L large-capacity coolant tank, maximum coolant flow 300L/min, matched independent oil chiller to control cutting fluid temperature constant, guarantee smooth chip removal and excellent workpiece surface finish. Complete hydraulic station supplies stable pressure for oil feeder clamping and tail positioning.

Safe Electrical Protection Configuration

The whole machine electrical cabinet equips leakage protection, complete safety interlock devices for all moving axes to avoid misoperation injury. Three-color running indicator light displays standby, running and fault alarm status clearly. All main drive motors, servo feed motors adopt reliable famous brand components, one-year full set wearable parts supply for after-sales support. Machine overall footprint 37m×3.5m, standard 380V 50Hz power supply, easy factory layout.

Wide Application Industries

Perfect processing equipment for hydraulic cylinder factories, heavy machinery manufacturers, coal machinery plants, petroleum equipment factories, mold shaft processing workshops, wind power long shaft production lines. Supports customized travel, center rest quantity, cooling flow and spindle power according to clients' special workpiece requirements.
