CNC contour grinding machine QMQ SUZHU GRINDER

– for wide range of castings

The patented SUZHU GRINDER’s are fully automatic CNC contour grinding machines and are suitable for complete grinding and de-burring of different kinds of castings with complex surface.

The SUZHU GRINDER’s have a high load capacity (casting weight up to 180 kg), a robust design and ensure high productivity due to rapid change over of work pieces.

The two-station turntable gives free access by hoist to the casting setting and pick-up place, while the second casting is machined at the same time. One worker may control two machines.

The 4-axis-motion system SIEMENS SINUMERIK 828D and the high precision six servo-drives and linear guidance’s assure high repeatability of grinding process and low grinding tolerances. Exactness of positioning of grinding tools +/- 0.1 mm. Repeatable casting grinding result is less than +/- 0.5mm, very close tolerances.

For new castings, contracted service or own foundry staff, building up the database for specific customer’s castings off-line.

Two different kinds of diamond grinding tools with excellent lifetime allow grinding of different castings of arbitrary shape, with rapid and thorough grinding of angles. It is not necessary to re-adjust the tool location, no wear compensation.

Supply in CE-conform execution with appropriate safety devices and enclosure. Connection to a dedusting system recommended. No pit, small foundation footprint.

Low investment and operating costs characterize the SUZHU GRINDER.
