ZSK2102 CNC Deep Hole Drilling Machine

1. Machine Overview‌
1.1 Machining Range
Drilling Range: Φ4–Φ20 mm
Maximum Drilling Depth: 1000 mm
Maximum Workpiece Length: 1000 mm

 

1.2 Machining Method
Gun drilling method, internal oil supply, external chip removal;
During machining, the tool rotates and feeds while the workpiece remains fixed.

 

1.3 Machine Overview
This CNC deep hole drilling machine is designed for deep hole machining, featuring fast, precise, and stable deep hole processing capabilities, suitable for deep hole machining of shaft components.
 

 

1.4 Machine Guideways: Rolling linear guideways.

1.5 CNC System: GSK

1.6 Bed Structure
The bed is made of resin sand castings, normalized after casting.
Ball screws and linear rolling guideways are installed on the tool bed for tool feed transmission.
The bed features peripheral cast oil return grooves, allowing cutting oil to flow back automatically into the tank.

 

1.7 Drill Box
Used to drive tool rotation.
A servo spindle motor drives the spindle via synchronous belts and pulleys, enabling stepless speed regulation with a maximum spindle speed of 5000 r/min.
A rotary union at the spindle's rear end delivers high-pressure cutting oil from the oil pipe into the high-speed spindle, supplying oil to the tool.
The main motor drives the spindle from the front, facilitating tool loading/unloading and preventing cutting oil from entering the motor, thereby extending motor service life.

 

1.8 Tool Feed System
Z-axis movement is driven by a servo motor and ball screw, allowing stepless adjustment of tool feed rate.
The Z-axis employs a ball screw with low friction loss, high transmission efficiency, high precision, capability for high-speed and micro-feeds, and high axial rigidity.

 

1.10 Cooling System
Comprises an oil cooler, chain-type automatic chip conveyor, filtration unit, and high-pressure pump assembly.
A variable-frequency motor drives a high-pressure gear pump to supply oil to the tool. By adjusting the motor's frequency, the output speed and pump flow rate are controlled, enabling precise regulation of cutting oil flow. The frequency control panel is mounted on the CNC operation station for convenient monitoring and operation.

 

1.11 Guide frame
Provides tool guidance, chip removal, and tool shank support. Equipped with a tool shank support sleeve at the rear for shank stabilization. A guide sleeve at the front guides the tool before it enters the workpiece, eliminating the need for pre-drilled guide holes and reducing machining steps and costs. The guide sleeve can move axially under hydraulic control to clamp or release the workpiece.

 

1.12 Hydraulic System
Controls the extension or retraction of the guide sleeve;
During machining, the hydraulic system extends the sleeve against the drilling entry point, retracting it after completion.
