2、 Innovation and advantages of Dema equipment
(1) Gantry frame structure, symmetrical structural layout
The bed, mountain shaped columns, and crossbeams form a gantry frame structure, which can enhance the rigidity and dynamic characteristics of the machine tool. Two main shafts are installed on the same spindle box and symmetrically arranged on both sides of the crossbeam to achieve balance between cutting torque and inertia torque.
(2) Introducing dual spindle balance force
Dual spindle simultaneous machining balances the torque received during single spindle machining, reduces tool deformation, and improves accuracy. Through simulation verification, the force stiffness of the dual spindle is increased by four times.
(3) Lightweight design of moving parts
By using finite element topology optimization design, weight reduction can be achieved while maintaining stiffness, which can effectively reduce inertial forces and make the motion of the machine tool easier to control.
3、 Configuration and performance
(1) Mechanical structure
The main body of the equipment is a "mountain" shape, with a large foot plate and a symmetrical spindle structure, which has advantages such as weight balance, force cancellation, and rigid feet.
(2) System electrical appliances
FANUC 0i-MF- α System package 1+AICC2 function+proflnet bus technology board, functional software, can be connected to automated robot production lines, achieving automation, unmanned, and automated production lines.
(3) Spindle unit
Equipped with HSK63-18000r/min electric spindle developed in cooperation with Dema Intelligent Machinery Co., Ltd. and Spindle Company, the spindle power is 18.5/26KW, and the maximum torque can reach 20-28Nm when operating at high speed of 11000r/min. Customers can choose the spindle model, power, and configuration according to their needs.
(4) Tool magazine
