Grunnleggende data

Product Overview

The High Precision CNC Profile Cylindrical Grinding Machine (Model MGK8320*300) from Zhejiang Quanshun Machine Tool Co., Ltd. is built for ultra-precise grinding of small-diameter, complex-profile components. Driven by linear motors on the X-axis and a direct-drive workhead motor, the machine eliminates mechanical transmission backlash, achieving a minimum feed and analytical resolution of 0.001mm and a headstock rotation resolution of 0.001°. Combined with a high-speed electric spindle running at 4000rpm and an 80m/s wheel linear speed, this machine is engineered for manufacturers producing small precision shafts, cams, and profile-ground components that demand both contour accuracy and surface finish consistency.

Key Advantages for Industrial Buyers

Linear Motor-Driven X-Axis — The X-axis (feed / wheelstock axis) is driven directly by a linear motor with 2200N thrust, removing backlash from ball-screw transmission and enabling faster, more precise profile-following motion.

Direct-Drive Workhead — The workhead motor uses direct-drive technology (1500Nm), and an optional DD motor configuration enables fully automatic headstock rotation for synchronized profile and cam grinding.

Sub-Micron Positioning Resolution — X/Z-axis minimum feed and analytical resolution reach 0.001mm, with headstock rotation resolution as fine as 0.001°, supporting complex, high-accuracy profile geometries.

High-Speed Electric Spindle — The standard electric spindle configuration runs at 4000rpm with an 80m/s wheel linear speed, delivering efficient stock removal while preserving fine surface finish on small-diameter parts.

Compact Precision Range — Purpose-built for external grinding diameters from Φ5mm to Φ200mm with a 250mm center distance, ideal for small precision shafts and profile components rather than large-batch heavy shaft work.

Adjustable Working Head Rotation — The working head rotates up to 15° (standard manual rotary type), allowing flexible setup for angled and profile grinding operations beyond straight cylindrical work.

Applications

This machine is designed for small-diameter, high-precision profile and contour grinding applications, including:

Cams and camshaft profiles Small precision shafts and pins
Valve stems and precision spool components Small cutting tool bodies and blanks
Non-circular and multi-radius profile parts

Why Choose Zhejiang Quanshun Machine Tool

Zhejiang Quanshun Machine Tool Co., Ltd. engineers the MGK8320*300 for applications where standard cylindrical grinders fall short on contour accuracy. By combining linear motor feed axes, a direct-drive workhead, and a high-speed electric spindle, the machine delivers sub-micron positioning and fine surface finish on small, geometrically complex parts. We support configuration options including automatic DD-motor headstock rotation, wheel specification, and spindle speed range to match specific profile-grinding applications, along with technical consultation, installation guidance, and after-sales support.

Frequently Asked Questions

What makes this a "profile" grinding machine rather than a standard cylindrical grinder?

The machine combines a linear motor X-axis, a direct-drive workhead, and 0.001° headstock rotation resolution, allowing it to follow complex, non-circular contours such as cams and multi-radius profiles — not just straight cylindrical surfaces.

What size workpieces can this machine grind?

The external grinding diameter range is Φ5mm to Φ200mm, with a 250mm center distance, making it suited to small-to-medium precision components rather than large heavy shafts.

What is a linear motor axis, and why does it matter?

A linear motor drives the axis directly without a ball screw or gearbox, eliminating mechanical backlash. This gives the X-axis (2200N thrust) faster response and more consistent positioning accuracy for fine profile work.

Can the headstock rotate automatically for cam or profile grinding?

The standard configuration uses a manual rotary working head with up to 15° adjustment. A special configuration can add a DD (direct-drive) motor for fully automatic, synchronized headstock rotation.

What spindle speed and wheel speed does this machine run?

The standard electric spindle configuration runs at 4000rpm, with a grinding wheel linear speed of up to 80m/s, using a Φ400x40x203 wheel.

Can specifications be customized?

Yes. Zhejiang Quanshun Machine Tool offers customization of spindle configuration, headstock rotation type (manual or DD automatic), wheel specification, and motor power based on specific profile-grinding requirements.
