It uses stepless speed control to adjust the grinding speed for different parts. It uses electro-pneumatic proportional valve closed-loop feedback pressure control, and the pressure device can be adjusted independently. The upper plate has a slow-down function to prevent thin and brittle workpieces from breaking.
A time relay and a grinding counter set and control grinding time and grinding revolutions according to processing requirements. The pressure mode can be adjusted during work. When the set time or revolution count is reached, the machine stops automatically and gives an alarm, enabling semi-automatic operation. Adding a thickness grating scale forms closed-loop control. When the set thickness is reached, the machine stops automatically for online production control.
The main unit is driven by a speed-adjustable motor and equipped with a high-power reduction system. Soft start and soft stop give stable operation.
The upper and lower grinding discs, sun gear, and planetary wheels form a coordinated grinding motion in four directions and speeds during processing. This grinds both surfaces at the same time with high efficiency.
The lower grinding disc can be raised and lowered for easy workpiece loading and unloading. The pneumatic sun gear reversing device precisely controls grinding accuracy and speed on both sides of the workpiece.
A correction wheel is supplied for correcting parallelism error between the upper and lower grinding discs.
Grinding efficiency is closely related to abrasive. Two main abrasive methods are used. One is external abrasive, also called free abrasive. Its disadvantages are insufficient abrasive supply on the upper disc, uneven abrasive distribution on the disc, most abrasive not participating in grinding, higher cost, and poor process stability. The other is Laptech fixing abrasive in the grinding disc, also called fixed abrasive. It solves the problems of insufficient abrasive supply on the upper disc and uneven abrasive distribution, and greatly reduces grinding cost.
We can machine custom grinding discs, correction wheels, planetary wheels, and other precision parts for double-side grinding machines from customer drawings, for single-piece or low-volume production.
Our custom precision component machining capability is not limited to double-side grinding machines. Beyond grinding discs, correction wheels, planetary wheels, and carriers, we also machine yacht precision components, RC car structural parts, medical device parts, and non-standard parts for tobacco packaging machinery, filling machinery, and printing machinery. Hansheng Automation works from customer drawings and production quantities to deliver single-piece or low-volume precision machining.
