Where The Parts Are Made
Our production line covers the three steps that decide whether a spare part fits: machining, heat treatment and grinding. Bodies, bushes, spindles and feed wheel hubs are turned and milled on CNC lathes and machining centres. Cutting parts - trimming knives, insert knives and band saw blades - are ground to the final edge geometry, and carbide tips are brazed and then re-ground so the brazing seam does not
affect the cutting angle.
Assembly And Testing
Grinding machines are assembled, wired and run for at least thirty minutes before they are crated, so the tooth index and the motor load are checked under real working conditions, not on a bench.
Inspection Before Packing
Every batch is measured against the OEM drawing: critical dimensions, hardness where it matters, and edge condition under magnification. The batch is photographed and recorded with its OEM number, material lot and production date, so a claim a year later can be traced back to the exact run.
Send a drawing (2D or 3D), a sample, or an OEM part number. We check manufacturability first and send back the tolerances and material we would use before quoting, so there are no surprises at the first article. You approve a sample, we run the batch, and your brand goes on the box - including buyer's carton, labels and packing list, with your part numbers, not ours.
When a part is discontinued or the original design causes a problem, we propose the design change instead of copying the old part. This is how our own product line grew: customers asked for a part nobody made any more, and we designed a replacement, tested it on real blades, and put it into our catalogue. Drawings and tooling stay confidential and are covered by NDA on request.
Stock items from 1 piece. Custom production from 50 pieces, with 15 to 25 days lead time.
What We Research
Our R and D work is practical: it starts from a complaint or a worn part, not from a product plan. When customers report that a knife wears too fast, a feed wheel slips, or a sharpened blade loses its angle across the width, we measure the failure and redesign the part.
Registered Technology
The swing-angle indexing mechanism used in our CNC blade sharpening machines is protected by Chinese utility model patent ZL 2025 2 2547849.7, granted by CNIPA on 23 October 2026. It keeps the tooth angle constant across the full blade width, which is what produces a uniform tooth profile on band saw blades from 15 to 100 mm rather than a blade that sharpens well at one end and poorly at the other.
How We Work
Parts are modelled in CAD, prototyped in small runs, and tested on real blades and real machine models before they enter the catalogue. Reverse engineering from a worn sample is routine - send the part with a photo and a scale, and we will reproduce the geometry and tell you what material it should have been made from.
