Main drive system

The spindle adopts precision grade bevel ball bearing with high speed and high precision, and the standard speed can reach 8000rmp.
The high-strength and tough four-claw broach has a large contact surface, strong gripping force, small loss of the shank head and long service life.
The standard machine uses a high-powered spindle servo motor for high-speed heavy cutting.
The spindle is driven by a high-torque toothed belt, which does not slip, and can greatly reduce transmission noise and heat generation.

Spindle design with precision ceramic bearings up to 12,000 rpm for high-speed cutting (optional).
Using the IRD dynamic balance correction device, the spindle dynamic balance is directly corrected on the line, so that the spindle avoids resonance when it is running at high speed, ensuring the best machining accuracy.

Structure Cylinder Knife Fight
The cutter mechanism adopts the floating knife principle, so that the force will not be transmitted to the spindle bearing when the knife is used, so as to increase the spindle bearing life.

The knife-cylinder type is combined with the advantages of the cylinder and the oil cylinder to improve the design. The hydraulic oil is strictly isolated from the compressed air. The piston rod in the cylinder automatically starts when it contacts the working piece, the movement speed is fast, and the pneumatic transmission is stable, and the cylinder device is simple. The output adjustment is easy. Under the same conditions, the high output of the hydraulic press can be achieved, the energy consumption is low, the installation is easy, and the special booster cylinder can be installed at any angle of 360 degrees. The fault is less troublesome, the service life is long, and the noise is small.

Main Shaft Oil Cooling System
The spindle high-speed operation is matched with the spindle oil temperature control system, which can effectively achieve the constant temperature effect of the spindle, effectively control the thermal displacement of the spindle, and ensure the high-speed and high-precision of the spindle.

Higher configuration

The Fourth Axis
The CNC rotary table adopts an equal-part turntable with end-toothed indexing. The indexing-end toothed disc includes centripetal, straight-tooth, curved-toothed teeth, etc. In order to achieve high-precision indexing, the end-toothed disc is generally hardened. The method of steel tooth surface grinding can meet the requirements of high rigidity and high precision, but the fraction of the index is limited by the number of teeth of the tooth plate.

The Fifth Axis
The CNC tilting rotary table is mainly used on the machine tool of CNC machine tool machining center. It can control the rotation and tilt of the turntable by using the two control coordinates of the original machine tool. It can also directly use the CNC device and machine tool supporting the turntable to complete the required work cycle. . It can complete holes, grooves, plane machining at any angle, as well as machining of curves, cams, etc., and achieve high precision.


High performance inspection system

Laser Interferometer
1. Laser interferometer can be used to detect straightness, verticality, pitch and yaw, flatness, parallelism and so on.
2. Detection of positional accuracy and its automatic compensation: It can detect the positioning accuracy of CNC machine tools, repeat positioning accuracy, and micro-displacement accuracy. The Renishaw laser interferometer not only automatically measures the machine's error, but also automatically compensates for its linearity error via the RS interface, saving a lot of time compared to the usual compensation method and avoiding manual calculations and manual CNC typing. Operator error, while maximizing the number of compensation points on the axis being measured, to achieve the best accuracy of the machine.

Ballbars
The Renishaw ballbar can test XY, YZ, ZX, and 3 orthogonal planes centering on a reference point. A single simple hardware setup means faster testing and the ability to create typical positional accuracy spatial measurements. The ballbar instrument retains the principle and powerful software of a simple CNC machine tool rounding inspection program. These advantages combine to quickly diagnose and quantify machine positioning errors, including servo mismatch, creep error, backlash, repeatability and proportional mismatch, and geometric accuracy errors, and then give the overall roundness error value.
