Large Positioning Block Corner Cutting Machine Large Fence – NN37
The large positioning block corner cutting machine large fence NN37 is the heavy-duty aluminum V-groove positioning guide for the large fence (大靠尺) system on corner cutting machines. When working with thick, wide, or tall frame profiles—such as heavy hardwood moulding or wide aluminum extrusions—the larger dimensions of the NN37 provide the stability and clearance needed for accurate, consistent miter cutting.
Designed for Larger Frame Profiles
The NN37’s 65mm height (vs 45mm for the NN36) and 70mm depth accommodate frame profiles that are too tall or thick to position accurately against the small fence block. The deeper V-groove provides more contact with the profile, preventing rocking or tilting during the cutting stroke. This is critical for achieving clean, flush miter joints on premium frame mouldings.
Specifications
The NN37 large positioning block corner cutting machine large fence measures 65mm in height, 70mm in depth, and 80mm in width—the same width as the NN36. The aluminum alloy construction provides rigidity and corrosion resistance. The thumb screw locking mechanism allows secure clamping to the large fence rail at any position within the fence’s adjustment range, with quick release for repositioning between different frame length setups.
Using the Positioning Block System
For professional frame production, set the NN37 on the large fence rail at the measured distance from the blade equal to the desired cut length. Lock the thumb screw. Run frame profile pieces against the V-groove stop to cut each piece to the same length. For batch cutting of multiple identical lengths, the batch cutting block accessories (NN41, NN42) supplement the positioning block to enable multi-piece cutting setups.

Durability and Maintenance
The NN37’s aluminum body resists corrosion and withstands the repeated impacts of frame profiles being positioned against the stop surface. Keep the V-groove and thumb screw thread clean of sawdust and metal filings. Periodically check that the locking screw fully clamps the block to prevent movement during cutting.
