Product details
Feature:
QD860 is a CNC step cylindrical grinding machine newly developed by Qiandao Precision Machinery. It is a cost-effective grinder, suitable for molding rod shape processing, mainly for outer circle grinding, and can carry out chamfering, taper, arc, plane, etc.
Machine Body
Machine tool are made of natural marble components, with good stability.
The machine tool adopts a fully enclosed appearance (movable sliding door on the front, maintenance doors on the left and back), cantilever control panel, handheld electronic handwheel, special start-stop button and foot switch, equipped with automatic cooling oil cooler and workpiece cooling Liquid control device, automatic lubrication device and mist suction interface, alarm buzzer, and electrical box cooling air-conditioning make the operation, maintenance, and maintenance changes of the machine tool simple and convenient.
Spindle head(C-axis)
The grinding wheel module adopts the grinding process of two grinding wheels at the same time, respectively rough grinding and precision grinding. According to the shape of the workpiece, the rough grinding wheel and the precision grinding wheel grind the workpiece successively and finish the process of two grinding degrees of the workpiece at one time, which improves the processing accuracy and efficiency.
The workpiece spindle(A-axis)
The workpiece spindle adopts two kinds of motorized spindle and belt drive shaft, equipped with Schaublin chuck body and collet, and the workpiece is automatically clamped.
System
The machine adopts an Anca control system and servo unit, adopts Renishaw precision probe, a German precision rolling rail, and a Japanese ball screw to ensure the superior performance and working accuracy of the machine.
At the same time, the machine is equipped with Japan NSK ball screw and German INA linear guide rail to better cooperate with the system, which can fully meet the requirements of cylindrical grinding.
