Steering oil port grinding machine

Description:

2MK9212 is mainly developed for precision grinding of metering edges, R flute,  etc. on hydraulic oil input sleeve(outer) of hydraulic power steering system of automobiles in mass production.

Features:

1.Modern industrial exterior.

2.Fanuc 0i-TF NC system equipped for easy operation.

2.1 NC(programable axes)

axis	function	type	remark
Y	vertical traverse of CBN wheel, for R flute grinding. Renishaw probe vertical motion.	linear	full closed-looped (with precise grating scale)
X	cross–feed of wheelhead, for metering edge grinding.	linear	full closed-looped (with precise grating scale)
C	rotation of workpiece.	circular	full closed-looped (with precise grating scale)
Z	working table longitudinal traverse.	linear	semi closed-looped

3. Dual grinding heads: one for cylindrical grinding(400 mm diameter corundum grinding wheel), to grind the metering edges; one for axial grinding(20mm diameter CBN grinding wheel), to grind the R flute ; Metering edges and R flute grinding can be achieved in one set-up.
