T型槽或螺纹孔

Modular mounting and positioning features on granite base platforms for industrial machinery.

技术定义与适配语境
典型 T型槽或螺纹孔 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

T-slots are precisely machined grooves with undercut T-shaped profiles running along granite base surfaces, allowing secure clamping and positioning of machine components using T-bolts. Threaded holes are tapped holes with standardized threads (typically metric or imperial) drilled into the granite, providing direct threaded fastening points. Both features enable flexible, rigid, and repeatable mounting of equipment, fixtures, and accessories on vibration-damping granite bases in precision manufacturing environments.

定义
T-slots are precisely machined grooves with undercut T-shaped profiles running along granite base surfaces, allowing secure clamping and positioning of machine components using T-bolts. Threaded holes are tapped holes with standardized threads (typically metric or imperial) drilled into the granite, providing direct threaded fastening points. Both features enable flexible, rigid, and repeatable mounting of equipment, fixtures, and accessories on vibration-damping granite bases in precision manufacturing environments.
工作原理
T-slots work by accepting T-bolts that slide into the slot and rotate 90 degrees to lock under the overhanging edges, distributing clamping forces across the granite surface. Threaded holes provide direct threaded engagement for bolts or studs, creating fixed mounting points. Both utilize granite's dimensional stability, mass, and vibration-damping properties to maintain alignment and reduce machine tool errors.

常见问题

What are the advantages of T-slots over threaded holes on granite bases?

T-slots offer greater flexibility for repositioning components without retapping, while threaded holes provide higher rigidity and load capacity for permanent mounts.

How do you maintain granite T-slots and threaded holes?

Clean regularly with compressed air and mild detergent, avoid abrasive cleaners, and inspect for chipping or thread wear; use thread inserts if threads strip.

Can T-slots and threaded holes be added to existing granite bases?

Yes, but requires precision machining by specialists to avoid cracking the granite; retrofitting is costly and may affect structural integrity.
