cnc cylindrical grinder

-- Steady & Reliable Manufacturer --

Zhejiang Quanshun Machine Tool Co., Ltd. manufactures CNC cylindrical grinders for precision processing of shafts, rollers, spindles, hydraulic rods and other cylindrical components. The machine supports efficient grinding of straight, tapered and stepped diameters, making it suitable for different part sizes and production requirements. CNC-controlled grinding cycles help reduce manual adjustments and maintain consistent machining quality during repeated production.

Designed for manufacturers seeking precision, stability and production flexibility, Quanshun CNC cylindrical grinders can be configured according to different workpiece and process requirements. Depending on the application, customers can select high-precision configurations, automatic loading and unloading systems, or customized grinding solutions. With in-house R&D and manufacturing capabilities, Quanshun can also provide technical support, software, operator training and non-standard machine development for specific production needs.

Bed length, swing diameter and wheel-head travel are selected to match your longest and largest workpiece — send your part drawing for a configuration recommendation.

Workpiece Range

Handles external, taper and step-diameter grinding on shafts, pump/motor rotors, hydraulic cylinder rods, printing and steel-mill rollers, spindles and bearing seats. Diameter range typically Ø10–500mm with length up to 3000mm, in hardened steel, stainless steel or cast iron.

Tolerance & Output

Achievable tolerance is IT5–IT6 with roundness ≤0.002mm. An internal grinding attachment can be added for bore work on the same machine, and stored CNC programs let repeat parts be reloaded without re-setting each dimension manually.

Core Functions

CNC interpolated straight, taper and profile grinding in one program
Automatic wheel dressing cycle with programmable dress compensation
Optional in-process gauge for closed-loop diameter control on critical parts
Stored part programs for fast changeover on repeat production jobs
Automatic tailstock quill control synchronized with the grinding cycle
Wheel balance monitoring to maintain finish quality as the wheel wears

Quality Control

Geometric accuracy of every machine tested against national inspection standards
Grinding wheel balance test performed before final assembly
Trial grinding on a customer-supplied sample part prior to shipment
Roundness and surface-finish verification with calibratedmeasuring instruments
ISO9001-certified process with warranty coverage and spare-parts support

FAQ

Q: How is this different from a dedicated crankshaft grinder?
A: A CNC cylindrical grinder machines straight or tapered outside diameters on centered workpieces, while a crankshaft grinder adds an orbital work-head specifically for off-center crankpins; choose this machine for general shaft/roller work.

Q: Can it grind tapers and stepped diameters, not just straight shafts?
A: Yes, the CNC axes are programmed for taper and profile grinding as standard, so straight, tapered and stepped sections can be finished in one setup.

Q: How often does the wheel need dressing?
A: Dressing frequency depends on material and stock removal, but the automatic dressing cycle can be programmed to trigger at set intervals or part counts to keep finish consistent.

Q: What is the lead time for a custom bed length?
A: Standard models ship in about 45–60 days; custom bed lengths or added internal grinding attachments typically add 2–3 weeks.

Q: Do you provide spare parts and after-sales support?
A: Yes, wear parts, spindle service and remote troubleshooting support are available after installation, along with on-site training if required.
