Normal Horizontal Cylinder Deep Hole Drilling and Boring Machine

DB-350 DB-350A

Main Outlook

Summary

Machine Summary

This machine is specially designed for deep hole processing of cylindrical workpiece.
It can perform different processing, such as drilling, boring, expanding and roller burnishing, etc. Besides machining through-hole, it can also process step hole and blind hole.
The machine tool is suitable for production of special cylinder, coal cylinder, hydraulic machinery, high pressure boiler tube, petroleum, military, electrics and airspace, etc.

Main Performances

Performance and Features

The process adopts the mode of workpiece rotating and tools feeding, if necessary the tool can be also rotary. With the workpiece rotating and the tool feeding.
The cutting fluid reaches the cutting area by oil supply device or through boring bar end, the chip removal adopts BTA type. When boring, cutting fluid pushes chips forward out of headstock end.
The machine can be equipped with drilling box, achieving double rotation of workpiece and tools, and the single action is also available for meet the different processing demand. Under the conditions of lower speed rotation of the workpiece, the processing efficiency and quality can be assured.
The machine has a wide application according to different processing demand.
DB-350 is equipped with workhead box, but isn't equipped with boring box or drilling box; DB-350A add to boring box or drilling box on the basis of the DB-350, so higher efficiency machining deep hole for cylindrical workpieces.

Packaging & Shipping

Firstly packed by waterproof cloth and then in wooden case.
Few parts may need to be taken down and be packed in wooden case.
According to customer's different require, wo can adopt different packaging.

Whether CNC deep hole honing machine or CNC deep hole drilling and boring machine or CNC deep hole skiving roller burnishing machine, we all use the same standard Packagings.
