Superhard tool grinder, which consists of four parts: the grinding wheel rocking axis (X-axis), the grinding wheel inclination angle (B-axis), the arc within the sea level of the 

steel part (C-axis), and the steel tool-feeding axis (Y-axis). axis composition. Among them, the steel cutting axis (Y-axis) is equipped with a grating ruler to provide closed-loop

control position feedback to ensure μm-level cutting precision. This CNC lathe is suitable for manufacturing a large number of alloy inserts, PCD cutter heads and CBN cutter 

heads. As long as the centering is performed, as soon as the power switch is pressed, the system will automatically cut under the action of the hammer force, achieving the 

ideal state of "constant current cutting, soft tool feed". Due to the high strength of the diamond material (PCD), the grinding wheel blades are damaged quickly. The system 

can automatically identify such damage and compensate for it, maintaining the cutting accuracy for a long time.

CNC lathe characteristics

(1) CNC lathe mechanical system

The superhard tool grinder body (base) is made of a single casting weighing about 1.5 tons, which can meet all superhard material cutting requirements. The CNC lathe has 

a grinding fluid protective cover to ensure that the grinding fluid is not easily splashed around. The optical lens barrel and CCD camera are equipped with protective covers 

to ensure that the wide-angle lens does not leak during operation and to ensure that its optical adjustment is not inadvertently changed. The interior of the CNC lathe is 

equipped with lighting fixtures and CNC lathe bedside table lamps. The cross operating table adopts high-precision slide rails, and the two extruder screws are tightened. 

This completely solves the gap and can withstand large cutting forces without cutting.

(2) CNC lathe high-speed electric spindle

The grinding wheel uses a high-precision AC motor speed-adjustable high-speed electric spindle, output power: 3.OKW, speed ratio reaches 3000 rpm, and circulating 

cooling water is used. The rotation precision of the grinding wheel spindle bearing: end runout 0.002mm, radial runout 0.003mm.

(3) CNC lathe slide rail

The use of high-precision needle roller slide rails significantly enhances the rigidity, precision and durability of CNC lathes.

(4) Servo mechanism

Adopting a control servo motor structure, the two parallel cutting axes (X and Y axes) and the two arcs (C and B axes) are controlled by AC servo motors, and can perform 

four-axis linkage under the driver of program execution. The cutting efficiency is improved and the tooth surface cutting quality is improved.

(5) Grinding wheel reciprocating rocking mechanism

The grinding wheel oscillates under the drive of the AC servo motor, the oscillation frequency is 0-50 times/min, and the oscillation intensity can be adjusted freely between 

0 and 120mm, so that the grinding wheel blades are evenly consumed and self-sharpened in a timely manner to ensure cutting precision and surface roughness. Spend. The 

mechanical vibration controlled by the CNC machine tool system, the shaking force, the shaking frequency and the shaking position can be set in the program.

(6) Angle servo motor

After inspecting the CNC blade, the cutting part of the CNC blade can be accurately repaired to avoid the disadvantages of the CNC blade being out of calibration after 

repeated cutting. The digital display servo motor has a viewing angle of 1'.

(7) Axial clamping of the grinding wheel shaft

The axial clamping technology of the grinding wheel spindle makes the two arc-shaped slide rails hug each other tightly, achieving stable contact without gaps, which greatly 

improves the rigidity of the equipment and improves the cutting quality of the CNC blade tooth surface. One level.

(8) Pipe buckle

The CNC lathe is equipped with a positioning tube buckle, which eliminates the need to adjust the position of the CCD camera when cutting CNC blades of different 

thicknesses, improving efficiency.

(9) Air intake system

The air intake system adopts a continuous fully automatic air intake system. Customers can set the oil supply time and intermittent oil supply time to ensure the service life 

of the screw nut.
