CNC Grinding Machine For Screw Sleeve

Full Model Range, One Supplier — From small sleeves (Φ8–200mm) to large screw sleeves up to Φ500mm and 3000mm long, customers can source across the full production range from a single, consistent machine platform.

Consistent 0.001mm Resolution Across All Models — Every model in the series shares the same minimum pulse resolution of 0.001mm on both X and Z axes, so grinding accuracy does not compromise as capacity scales up.

Scalable Servo Torque — X/Z-axis servo motor torque scales with each model (6Nm / 16Nm / 22Nm), matched to the load and grinding force required for that model's capacity range.

Flexible Length Configuration — The MK8350 series is available with four grinding-length options (1000/1500/2000/3000mm), letting customers match machine length to sleeve length without paying for unused capacity.

Stable Grinding Wheel Speed — All models run a consistent 45m/s wheel linear speed, providing predictable stock removal rates and surface finish when moving production between model sizes.

Heavy-Duty Option for Large Sleeves — The MK8350 series handles workpieces up to 1000Kg with a 6# Morse taper headstock and tailstock, suited to large industrial screw sleeves and lead screw components.

Zhejiang Quanshun Machine Tool Co., Ltd. offers the screw sleeve grinding series across three model tiers so customers do not have to compromise between machine capacity and budget. Each model shares the same servo-driven, high-resolution CNC control architecture, giving consistent grinding accuracy whether the workpiece is a small sleeve or a large 3-meter screw component. We provide guidance on model selection based on sleeve dimensions and production volume, along with custom configuration, installation support, and after-sales service.

Which model should I choose for my screw sleeve?

Model selection depends on sleeve diameter and length: MK8320H suits small sleeves up to Φ200mm/500mm long, MK8332B suits mid-size sleeves up to Φ320mm/1000mm long, and MK8350 covers large sleeves up to Φ500mm and 3000mm long.

Do smaller models sacrifice grinding accuracy compared to larger ones?

No. All three models share the same 0.001mm minimum pulse resolution on the X and Z axes, so grinding accuracy remains consistent regardless of which model is selected.

Can the MK8350 series be customized for a specific grinding length?

Yes. The MK8350 series is available in four standard grinding-length configurations — 1000mm, 1500mm, 2000mm, and 3000mm — to match different screw sleeve lengths.

What is the maximum workpiece weight across the series?

Maximum workpiece weight is 50Kg for MK8320H, 150Kg for MK8332B, and 1000Kg for the heavy-duty MK8350 series.

Can specifications be customized beyond the standard models?

Yes. Zhejiang Quanshun Machine Tool offers customization of grinding length, headstock/tailstock taper, wheel specification, and motor configuration based on specific screw sleeve requirements.
