Motion Methods Introduction

The motion mode of this CNC machine drill is as follows: its working table is not movable, the gantry column and crossbeam move front and rear on the base (Y-axis), the sliding saddle and the main spindle box move left and right on the crossbeam (X-axis), and the main spindle box moves up and down on the sliding saddle (Z-axis).

Features of CNC High Speed Flange Drilling Machine

• To guarantee strong machining capabilities, the drilling head is composed of a mechanical spindle, a 15Kw AC servo motor, and a spindle box. The spindle box is cast from HT250 gray cast iron and has undergone secondary aging and annealing treatment.

• The beam, columns, base, and worktable are all robust, fully cast structures.

• The drilling spindle uses a high precision mechanical spindle from Taiwan with internal cooling. It is equipped with BT50 tool tapers that can be fitted with carbide internal cooling cnc drill bits and high-speed steel twist drill bits. This spindle is designed for low speed, high torque operations, so it can handle heavy cutting loads as well as rigid tapping. It's also suitable for high speed machining of carbide tools.

• The X/Y/Z axes adopt a dust-proof design to prolong the lifespan of the transmission components as much as possible.

• To protect the personal safety of machine operators, safety doors are installed around the workbench.

• The XYZ axes adopt linear roller guides, and the servo motor is directly connected to the high-precision balls screw through an elastic coupling. This system is characterized by high rigidity, low noise, low friction, flexible feeding, accurate positioning, and high transmission precision.

• All linear guide rails are equipped with pressure blocks to ensure smooth movement and high accuracy. The pressure block not only compresses and fixes the guide rail, but more importantly, it ensures the even distribution of force on the rails, thereby preventing it from being deflected, deformed, or damaged during movement.

• The vertical ram is a cast structure, and its Z-axis motion is guided by two linear roller guide pairs. The drive uses a servo motor to drive the synchronous belt (i=2) and a precision ball screw pair for transmission.

• The cnc tubesheet drilling machine is equipped with a carousel tool magazine that can get 16 tools accommodated.

• The machine is equipped system is a branded product from KND. It has an all-English keyboard, supports multiple languages, and has a very friendly operation interface for overseas users.

• Also, it comes with a manual pulse generator. This provides convenience for the operation of the machining origin setup.

• An automatic oil pump lubricates each transmission component; the operator only needs to set the lubrication time, and when the time is coming, the lubricator automatically starts oiling.

Application of CNC Drill Machines

Applicable Field

EagleTec drilling CNC machines are suitable for drilling, face milling, countersinking, and threading operations on ring items or products like flanges, tube sheets, slewing bearings, turntable bearings, valves, and more. Besides these, it is also widely applied in explosion-proof electrical industry, wind power industry, CNC machining industry, automovie industry, heat exchanger production etc.

Applicable Materials

Metals include steel, iron, aluminum, and copper. 

Optional Configurations Available for EagleTec CNC Flange Drilling Machines

Please choose configurations or options according to actual production needs:

Angle Head

This option enables the machine to do side drillings. 

Counter-Balance Cylinder

Chip Removal Machine

• On the back of the drill cnc machine, there is a chip discharge port on each side. The chips are sent to the chain plate outside the machine through the spiral mechanism on both sides of the worktable.

• When the waste chips reach the chain plate, they will be transferred to the collection truck by the chip conveyor.

• At the same time, the filtered water tank works together with the chip removal machine to recover the discharged coolant, filter it, and then recycle it. The tank is equipped with multiple filters to ensure that the recovered coolant does not cause damage to related components.

Operation Program for CNC Tube Sheet Drilling Machine

The KND CNC system comes with a built-in operating program. It has file management and program editing functions, which can quickly preview files, verify tracks, and improve operating efficiency. The software also has a built-in graphics library. For some common processing shapes, we can directly call the files in the graphics library and simply set the machining parameters before starting processing. There is no need to do modeling and generate NC code yourself. Of course, if you want to work a workpieces that are not in the graphics library, you still need to model and generate G code yourself.
