CNC Reciprocating Double Disc Grinding Machine MW7675B
CNC reciprocating double disc grinding machine is mainly used for grinding the inner and outer rings of large bearings and two ends of other large workpieces. The CNC reciprocating double disc grinding machine mainly comprises machine body, left and right grinding heads; left and right carriage; left and right feed compensation mechanism; front bed reciprocating mechanism; independent grinding wheel dressing mechanism; electrical control system; hydraulic system; special feeding fixture mechanism and other main components. The feed speed and dressing frequency of the grinding wheel of the CNC reciprocating double disc grinding machine can be preset and modified by the program. When the product is continuously ground to a set value, the feeding mechanism stops feeding first. After the workpiece in the grinding area is sent out, the left and right grinding heads will automatically separate to the dressing position and start to dress the grinding wheel automatically. After dressing, the left and right grinding heads will automatically enter the grinding position, and the feeding mechanism will automatically start to work to complete the automatic grinding cycle.
Features and benefits:
1. The grinding wheel feed of CNC reciprocating double disc grinding machine adopts high-precision ball screw, and the guide rail adopts V-shaped steel inlaid needle roller bearings.
2. The main shaft of the CNC reciprocating double disc grinding machine - the core component is made of 40Cr steel material, which has been forged, annealed, normalized, quenched and tempered, quenched and qualitatively treated. The machine has compact layout, scientific and reasonable design, sufficient rigidity and long service life.
3. The whole grinding head of the CNC reciprocating double disc grinding machine moves for grinding, instead of spindle telescopic movement for grinding, to complete grinding, so the machine has strong rigidity and outstanding stability. This structure maximizes its rigidity. The spindle is pre-tightened by constant force load, with large cutting depth and high precision.
4. The dresser of the CNC reciprocating double disc grinding machine is an integral structure. There is only one dressing arm. The two grinding wheels are dressed at that same time. The stability is good. The dressing precision is high, and automatic dressing and automatic compensation are achieved.
5. The bed of the CNC reciprocating double disc grinding machine is designed with heat insulation to ensure that the machine can work continuously for a long time without affecting the accuracy.
6. When the grinding wheel of the CNC reciprocating double disc grinding machine is worn to a limit size, the feeding mechanism will automatically stop and give an audible and visual alarm.
7. The grinding wheel protective cover of the CNC reciprocating double disc grinding machine can be automatically lifted and lowered. Safety interlocking has been equipped between the grinding wheel protective cover lifting-lowering and the grinding head rotation. The safety interlocking has been provided between the the dresser and grinding, so that the machine’s safety factor is high.
8. The CNC reciprocating double disc grinding machine can be equipped with an optional frequency converter to achieve the stepless speed regulation of the grinding head and achieve differential grinding.
9. CNC reciprocating double disc grinding machine can be equipped with optional servo motor to complete servo control feeding and compensation.
