specific Embodiment approach 1

[0010] Specific implementation mode one: as Figure 1-7 As shown, the double cutterhead horizontal ultra-precision hydrostatic electric spindle system of this embodiment includes a first fixed baffle 3, a first spindle 10, a motor bracket 18, a first thrust plate 4, a first cutterhead 11, The first shaft sleeve 8, the first shafting bracket 15, the first oil chamber cover 16, the housing 37 and the DC double output shaft motor 38, the main shaft system also includes the second fixed baffle 34, the second main shaft 28, the first Two thrust plates 22, a second cutter head 29, a second shaft sleeve 26, a second oil chamber cover 33 and a second shafting bracket 35; the first shafting bracket 15 is located at one end of the inner cavity of the casing 37, so that The first shafting bracket 15 is fixedly connected to the housing 37 through the first fixed baffle 3, the second shafting bracket 35 is located at the other end of the inner cavity of the housing 37, and the second shaft...

specific Embodiment approach 2

[0013] Specific implementation mode two: as figure 1 As shown, the DC dual output shaft motor 38 in this embodiment is a DC dual output shaft brushless drive motor. With such a design, the driving effect is good. Other components and connections are the same as those in the first embodiment.

[0014] The DC dual output shaft motor 38 of the present embodiment is composed of a stator 1 and a rotor 2, and the rotor 2 of the DC brushless drive motor system 38 is fixedly connected with the first motor shaft 19 and the second motor shaft 20 at the same time, and the brushless drive motor is used as The driving element, since there is no brush, there is no frictional moment between the stator 1 and the rotor 2 of this motor, and the rotational torque can be directly generated to drive the first main shaft 10 and the second main shaft 28 to rotate simultaneously and perform cutting.

The spindle system is used for machining KDP crystal optical parts.

Description

technical field [0001] The invention relates to a hydrostatic electric spindle system, in particular to a double-cutter horizontal ultra-precision hydrostatic electric spindle system. Background technique [0002] Driven by the technological demands of laser nuclear fusion and strong laser weapons, many countries have successively built multiple large-scale laser devices, requiring a large number of optical components. KDP crystals are widely used due to their high nonlinearity and laser damage threshold. Applied in the field of laser and nonlinear optics. KDP crystal optical parts require high-precision surface quality and good surface roughness, but KDP crystals are soft and fragile, which are not conducive to optical processing. Traditional grinding and polishing methods are not suitable for processing KDP crystals. Ultra-precision machining technology must be used to process KDP crystals. The processing of KDP crystals must use special KDP ultra-precision machining mach...
