ZSK2104 × 1000 CNC Deep Hole Drilling Machine

Machine Tool Overview

1.1 Processing scope

Drilling range: Φ6 ~ Φ40mm

Maximum drilling depth: 1000mm

Workpiece outer diameter range: Φ15 ~ Φ100mm

Maximum workpiece length: 1000mm

1.2 Gun drilling method, single/Double spindle structure, suitable for processing coaxial holes on shaft parts;

1.3 During the machining process, the tool and workpiece rotate relatively, and the tool is fed. Used for machining coaxial holes of shaft parts.

1.4 Workpiece clamping

The front end of the spindle of the head box and the guide frame is equipped with a conical disk, and the hydraulic system controls the axial movement of the spindle of the head box, and automatically clamps and positions the workpiece by using the chamfering of the conical disk and both ends of the workpiece.

1.5 The guide rail used on the machine tool adopts linear guide rail.

1.6 CNC system:Siemens 808

1.7 Drilling box

The servo main motor is used to drive the spindle to rotate through the synchronous belt and synchronous pulley, which can realize stepless speed regulation. The maximum speed of the spindle is 3500r/min, and the spindle is driven in front, which is beneficial to protecting the main motor and facilitating tool change.

1.8 Headstock

Drive the workpiece to rotate at a constant speed of 120r/min; The spindle can be axially moved under the control of the hydraulic system and is used to tighten or loosen the workpiece. The spindle is driven in front, which is convenient for loading and unloading workpieces and helps to protect the main motor.

1.9 Tool feed system

The structure of ball screw driven by servo motor can realize stepless speed regulation of cutter feed.

1.10 Drill pipe support

3 sets for supporting drilling bars.

1.11 Cooling System

It is mainly composed of high-pressure pump unit, chain plate chip conveyor, oil cooler, filter device, etc. On the CNC system operation station, assemble the cooling system flow adjustment panel.

1.12 Protection: The machine is fully protected.

1.13 Basic parts such as bed and box are cast with resin sand and have undergone twice aging treatment. The oil return tank of the bed body is inclined and will not store oil.

1.14 Guide frame

It is used for tool guidance, chip removal and supporting tool bars. The front end thereof is equipped with a guide sleeve for tool guidance; The rear end is equipped with a cutter bar support sleeve for supporting the cutter bar.
