The CNC grinding machine is mainly composed of a bed, worktable, electromagnetic suction cup, grinding wheel box, slide seat, column and other parts
CNC grinding machine is a machine tool that uses grinding wheels to grind various flat parts. Grinding machine is a commonly used type of flat grinding machine, with high grinding accuracy and smooth surface. It is easy to operate and suitable for grinding precision parts and various tools. CNC CNC grinding machine has four motors, namely grinding wheel motor, grinding wheel lifting motor, hydraulic pump motor, and cooling pump motor. The grinding wheel motor directly drives the grinding wheel to rotate and grind the workpiece. In a surface grinder, the grinding wheel does not require speed regulation, so a cage type asynchronous motor is usually used to drag it, which is the main motion of the surface grinder; The grinding wheel lifting motor makes the grinding wheel move vertically on the column guide rail to adjust the position of the grinding wheel and the workpiece
CNC CNC grinding machine:
1、 Grinding machine (CNC tool) and cutting tool grinding and cutting technology
2、 The first large-scale CNC precision vertical grinder has passed the appraisal in Tianjin
3、 Undertake the establishment work of the national grinding machine tool working group
4、 The CNC roll grinder was born in Shanghai and passed the user pre acceptance
5、 The largest CNC ball valve grinder produced in China
The reciprocating motion of the worktable and grinding wheel is driven by a hydraulic pump motor through hydraulic transmission. The hydraulic transmission is relatively stable and can achieve stepless speed regulation. When reversing, the inertia is small and the reversing is smooth. The reciprocating motion of the surface grinder worktable adopts hydraulic transmission, which can ensure machining accuracy. The hydraulic pump is driven by a hydraulic motor, and the reciprocating motion of the worktable is achieved through a hydraulic transmission device. The cooling pump motor drives the cooling pump to supply cooling fluid to the grinding wheel and workpiece, while using the cooling fluid to remove the ground iron filings
Analyze the causes of common faults in surface grinders, summarize typical fault types and maintenance solutions, and introduce maintenance strategies for grinders. This has certain reference and reference value for the use, maintenance, and upkeep of surface grinders
Typical Processing Techniques for Processed Products
(1) The machining of the chip groove of ordinary end mills adjusts the relative position between the grinding wheel and the workpiece through the movement of the X, Y, and Z axes; When grinding the chip groove, the A-axis rotates and the U-axis feeds linearly to complete the chip groove machining
(2) Machining of taper end mill chip groove. The taper end mill chip groove requires equal pitch and equal rake angle to ensure the same cutting performance at each outer circle of the end mill. Ordinary machine tools can only process equal pitch and equal front angle chip grooves, and cannot process equal pitch and equal front angle chip grooves. During processing, continuous trial grinding is required to obtain a more ideal groove shape. The machining process of CNC tool grinder is:
Adjust the relative position between the grinding wheel and the workpiece through the movement of the X, Y, and Z axes; When grinding the chip groove, the A-axis rotates, the U-axis feeds linearly, and the Z-axis moves from top to bottom to complete the chip groove machining
(3) The machining of the chip groove of the ball end milling cutter requires that the chip groove of the ball end milling cutter is a spiral groove, and the cutting edge passes through the center to ensure smooth cutting and convenient chip removal. The machining process of CNC tool grinder is to adjust the relative position between the grinding wheel and the workpiece through the movement of X, Y, and Z axes; When grinding the chip groove, the A-axis rotates, the U-axis feeds linearly, and the W-axis rotates to complete the chip groove machining
(4) CNC grinding machines for milling cutters, drill bits, and reamers can complete processes such as chip grooves, rake angles, rake angles, and cross edges by changing the grinding wheel clamped on the spindle
