DB-500 Heavy Duty Horizontal Cylinder Deep Hole Boring Machine

Heavy Duty Horizontal Cylinder Deep Hole Drilling and Boring Machine

DB-500    DB-500A 

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.

Performance and Features

• The headstock spindle is driven by large power DC motor, using multi-gear speed change and stepless speed regulation. The process adopts the mode of workpiece rotating and tools feeding, the coolant is supplied by the oil feeder or through the end of boring bar, the chip is pushed out by the coolant pressure.
• The headstock part is equipped with three-jaw or four-jaw chuck, the oil feeder clamps the workpiece by servo motor. The oil feeder can be moved and positioned along the bed body, and maintaining the constant clamping force to the workpiece. The hydraulic system has a good control when clamping and fixing the workpiece, which has a high stability and good precision. The oil feeder adopts the principal axis structure which improves the load-capacity and rotation accuracy.
• The bed body is made of high strength cast iron, which ensures the machine with enough rigidity. The guide track is treated by hardening technology and has the excellent wear-resistance and high precision retaining ability. All the operation parameters are shown by meter display where is located at the side of the machine’s middle part, the workpiece clamping and the operation is very safe, rapid and stable.
• DB-500 is equipped with workhead box, but isn't equipped with boring box or drilling box; DB-500A add to boring box or drilling box on the basis of the DB-500, so higher efficiency machining  deep hole for cylindrical workpieces.

Technical Parameters

The machine consists of bed body, headstock, drilling and boring box (optional), chuck body, feed carriage, oil feeder, cooling system, chip removal device, steady rest, hydraulic system, boring bar support, motor and electrical system, etc.

• 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.
