Product Description

CNC BTA drilling machine for tube sheet

Product Description

This machine is used for cylinder workpiece center hole or offer center hole drilling, especially for the twin barrel hole drill(we called it Ã¢Â€Âœ8”hole.)

 

Machine brief:

Machine processing capability:

Solid drilling diameter range

Φ30~Φ100mm (By BTA solid drill head)

Counter boring diameter range

Φ35~Φ200mm (By counter boring head,cutting volue 15mm in diameter

Max. Hole drilling depth

3000mm

Max. Workpiece length

3000mm

 Machine processing method:

 

Solid drilling mode

BTA drilling method(chips go out through drilling bar)

Hole boring process

Chips go out through workpiece’s cored hole.

Infeed method

Tooling is rotary and infeeding, the workpiece is fixed

 Main components:

 

Machine base, worktable, and other basic parts

  • HT300 iron, resin sand precise casting.
  • wice timing treatment, high rigidity and stability.

Workpice clamping

with 2 sets V type blocks to clamp the workpiece.

X-axis, Z-axis guide rails

Double rectangular sliding rails, precise grinding treatment, aging treatment, quenching treatment.

Drill bar box

  • The motor drives the spindle to rotate through the belt and gear box.
  • Rotary speed range: 70-1000r/min(2 grades,speed stepless adjustable), Main motor: 30kw(Inverter motor).

Tooling infeed system (Z-axis)

Adopts the servo motor driving the T type leading screw through the reducer structure. The speed is adjustable(stepless).

Drill bar rest

2 groups, supporting the drill bar.

Coolant system

To supply the oil for the tooling, consist of oil tank and 3 groups high press pumps.

Oil pressure head

  • The oil pressure head is used for cutter tooling guiding, oil supplying, supporting.
  • The oil pressure head is driven by ordinary motor to make axial movement.
  • The oil pressure head spindle can be pushed out and retracted under the control of the hydraulic system;
  • the oil pressure head can be automatically locked on the machine bed by the hydraulic pressure plate.

T-slot worktable(X-axis)

  • Horizontal director travel is 400mm; 
  • Driven by servo motor, servo reducer and ball screw; 
  • Worktable size 2400X600mm; 
  • Worktable weight loading 4tons.
  • The working table base and the cutting tool base are separately casted,assembled together through high strength bolts and positioning by taper pin.

Packaging & Shipping

1. Before shipment, every part of machine will be painted with a layer of anti-rust and water-proof oil to prevent possible erosion during transportation. 
2. A plastic cover to wrap around machine parts to enhance corrosion prevention. 
3. Export standard fumigated wood cases are measured and specially made for packing. 
4. Steel wire will be used to tighten and strengthen the packages inside container.
