There is a tool rest 44 that can walk along the beam, and a workbench 48 is provided between the two bases 47;

[0012] Described knife rest 44 comprises a support 1 that is installed on the described crossbeam 45, and the upper plane of crossbeam 45 is provided with two guide rails 8 symmetrically, is provided with two rollers 9 rolling on guide rail 8 correspondingly on support 1, in A rack 6 is provided on the crossbeam between the two guide rails 8, and a gear 7 meshing with the rack 6 is correspondingly provided on the bracket. The gear 7 passes through the bearing 10, and the flange 11 and a bracket 1 The reducer 12 is connected, and the other shaft end of the reducer 12 is provided with a lock nut 13; the lower part of the beam 45 is connected with the lower end of the support 1 through the vertical roller 2, and a transmission is provided on the upper part of the support 1 side. Nut 19, transmission nut 19 is provided with transmission screw rod 14, and transmission screw rod 14 is connected with a reducer 17 that is arranged on the flange 18 through bearing 15, is connected with vertical plate 49 on the base plate that flange 18 is installed, A motor 20 is arranged on the vertical plate 49, a pair of wheels 21 are arranged on the output shaft of the motor 20, an axle seat 50 is arranged on the bottom of the vertical plate 49, and skeleton oil seals 22, 30 and end caps are arranged at the two ends of the axle seat 23, 30, a pair of bearings 25 are provided in the shaft seat, and the bearings 25 are provided with a main shaft 26 through the outer lining ring 28, the inner lining ring 27 and the lock nut 24, and one end of the main shaft 26 is connected with the pair of wheels 21, The other end is connected with a cutter head 31 and a cutter head 32 .

[0013] Described beam driving mechanism 43 comprises speed reducer 37, and the drive shaft that is connected with speed reducer, is provided with gear 36 on the shaft, and drive shaft is installed on the support by bearing 38 and bearing block 39, and two pulleys are also housed on support 33, pulley 33 is installed on the support by pulley seat 41,42, bearing 34 and jump ring 35.

[0014] The invention consists of five parts: a tool spindle system, a tool holder, a beam, a base and a workbench. Driven by the motor, the tool holder can automatically run left and right on the beam, and the encoder counts to achieve precise positioning. The tool holder and the beam are connected by three-point positioning and a high-precision rack to achieve precise transmission. The tool spindle The system is driven by a screw nut, driven by a motor, and can automatically run up and down on the tool holder. The encoder is used for counting to achieve precise positioning; driven by the motor, the beam can automatically run back and forth on the base, and the encoder is used for counting. Accurate positioning is achieved; the upper part of the base is connected with a V-shaped guide rail and a high-precision rack and beam to achieve precise transmission. The lower part of the base adopts a skeleton structure, covered with iron plates, and the inner space of the base is used to make a locker, which is easy to move, beautiful and practical. The upper and lower parts of the base are connected by bolts, which are easy to disassemble and adjust; the workbench is fixed, and a layer of stone is bonded to the workbench, and the machine itself is used for milling and processing, so that the distance between the workbench and the tool surface is always kept equal.

[0015] The electrical control system of the present invention: the grinding disc is automatically lifted and lowered according to the set number; it has the functions of one-way processing and multi-directional compound processing; the functions of jogging, manual and automatic processing; different processing methods can be selected according to the characteristics of stone materials; digital fixed points are used for execution And digital quantitative automatic control; automatic alarm function, diagnosis function and help function; frequency conversion control technology. The grinding disc is automatically raised and lowered according to the set number. It has the functions of unidirectional processing and multi-directional compound processing. Inching, manual and automatic processing functions, different processing methods can be selected according to stone characteristics, digital fixed-point and digital quantitative automatic control for execution, automatic alarm function, diagnosis function and help function, frequency conversion control technology.
