技术定义与适配语境
典型 安装孔/特征 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。

Mounting holes and features are precisely machined openings, slots, threads, or recesses on the working surface of a surface plate, designed to facilitate the secure attachment, positioning, and alignment of workpieces, fixtures, jigs, or other equipment during machining, inspection, or assembly operations. These features ensure dimensional stability, repeatability, and accuracy in industrial setups.

定义
Mounting holes and features are precisely machined openings, slots, threads, or recesses on the working surface of a surface plate, designed to facilitate the secure attachment, positioning, and alignment of workpieces, fixtures, jigs, or other equipment during machining, inspection, or assembly operations. These features ensure dimensional stability, repeatability, and accuracy in industrial setups.
工作原理
Mounting holes and features provide mechanical anchoring points that distribute clamping forces evenly across the surface plate, preventing movement or vibration of mounted components. They enable precise location referencing through coordinate systems (e.g., grid patterns), allowing for consistent positioning and alignment using fasteners, dowel pins, or specialized clamps, thereby maintaining geometric tolerances in manufacturing processes.
材料
Typically made from the same material as the surface plate: cast iron (gray or ductile iron grades like ASTM A48)granite (black or pink granite with low thermal expansion)or steel (tool steel or stainless steel). Hardness and wear resistance are criticalwith cast iron often surface-hardened or coated for durability.
Depth
Through-holes or threaded blind holes (e.g., 20mm depth)
Flatness
Adjacent to plate flatness (e.g., 0.01mm per 300mm)
Tolerance
Positional tolerance ±0.05mm to ±0.2mm, hole diameter tolerance H7 or equivalent
Thread Type
Metric coarse (e.g., M8x1.25) or UNC/UNF
Hole Pattern
Grid spacing (e.g., 100mm x 100mm, 2" x 2") or custom layouts
Hole Diameter
M6 to M24 or 1/4" to 1" (standard metric or imperial sizes)
Surface Finish
Ra 1.6μm to 3.2μm for cast iron, smoother for granite
标准
ISO 8512-1DIN 876ASME B5.54

常见问题

What are the common types of mounting features on surface plates?

Common types include threaded holes for bolts, through-holes for clamping, T-slots for adjustable fixtures, and dowel pin holes for precise location. Grid patterns are standard for flexibility in positioning.

How do mounting holes affect the accuracy of a surface plate?

Properly machined mounting holes maintain the plate's flatness and provide reliable reference points, ensuring repeatable positioning within tight tolerances (e.g., ±0.1mm). Poorly executed holes can introduce errors or damage the surface.

Can mounting features be added to an existing surface plate?

Yes, but it requires precision machining (e.g., drilling and tapping) by a specialist to avoid compromising flatness. It's often better to specify features during initial manufacturing.
