Genmitsu 2PCS T-Track Mini Hold Down Clamp Kit, CNC Router Clamp for Woodworking and Metalworking, Compatible with 3018 CNC Router Machines, 3018-PRO/ 3018-PROVer/ MX3, 2.57’’Lx 0.79’’Wx 1.97’’H

Ottima qualità. Indispensabili....mi hanno cambiato la vita rispetto ai blocchi originali. Sicuramente da avere.

These clamps hold incredibly well. I use them with FoxAlien Masuter Pro; just remove the t-slot nuts. They are low profile and provide either a short or medium reach. The pivot on them helps to keep them secure and well-aligned, and they are easy to tighten and remove.

バネ+ポリアセワッシャーはいらないですね。ちょっとしたことでイラッとしますので、とっぱらいました。その後快適です。

Bought the 3018 Pro milling machine as an introductory tool to milling "bigger" things. The DIY project went together very nicely and ran the samples supplied with ease. What I didn't really care for the the clamping system supplied for the "Y" axis for many reasons I'll not go into here. I found these hold-down clamps advertised in their brochure and decided to try them. I use a lot of purchased and home made clamps for "T" gigs for metal and woodworking and have some much larger that wouldn't work with this smaller surface. The clamps arrived on time and in a very well protected holder for storage. They are very well made and worth the money, buttttt- now for a minor problem to dampen the glory. They have a spring that holds the center of the clamp up while adjusting and tightening the clamp, this was an annoyance as the spring would flex under the clamp and get into the threads of the clamp bolt preventing it to be tightened down any further until it was pulled out of the threads. The spring is tapered with the large end sitting against a nylon washer under the clamp arm. To eliminate the problem I machined shoulder washers for the two clamps that keep the spring centered on the screw and moved the nylon washer to the top just under the star nut. Works great and I'm sure you can find shoulder washers online if you want to do the same. Was just a little more fun and experience making my own!. FYI, the screws are M6x1 thread.

They are designed for small machines as indicated by the description. If you have a small machine you are also aware that height clearance is vital. These clamps have a nice and low profile that is needed for using a small machine and they are many times better than the various makeshift clamps I made previously. I have since bought a second set and now only need to use these.
