The 9/16"diax3/16"deep counterbores are for usage with our speedy locate and fasten systems. These allow our vises and fixtures, and other hardware to be located and bolted down with one fastener. The tolerance on these is rougher than the precision bores (.003") but try it out, you will find that almost every time the fixture
The best answer is AIR CONDITIONING, but if you are not in a air conditioned space we suggest flood coolant. Regular usage of flood coolant will keep any rust from forming on your plate. The coolant has Rust Inhibitor chemicals in it to aid with this. The Hot Black Oxide really helps with the medium
In a review of Tosa Tools Modular Fixturing Systems Bob Warfield of CNC CookBook made a suggestion to put a thin film of it between the modular subplate and the machine table. Since then it has been asked for many times and we decided to offer it in a convienant size for our customers who
Tosa Tool now offers the "Add Bushings" option for your modular plates. Our Bushings are wear resistant steel and hardened to Rockwell C 58, precision ground, and they are press-fit into the dowel positions in your modular plate. This adds considerable cost but insures durability and proper bore fit. We also offer kits to install
Our standard grinding is .002" over 24", and it may actually be better but, if you have to have ultimate precision, we recently have found a partner in our area who can deliver the HIGHEST POSSIBLE GRINDING TOLERANCES for our line of modular plates. We call it SUPER GRIND (+/-.0003 over 50" on parallelism). Check
In April of 2019 we began a reorganization / update / upgrade of our website and the addition of all the designs we have made over the years. It is a huge task. One of the things we did was to rename the products to more accurately describe what they are and the machines they
Tosa Tool recommends any work holding device (fixture plate, vise, 4th axis, etc) be periodically removed and cleaned. This interval depends on personal preference, frequency of use, types of material being cut, coolant and more but generally should be inspected every 3-12 months.
Standard lead time is three to four weeks from order. We keep stock on hand for some standard fixture plate sizes but machine the plates on a just-in-time basis. Certain plates for popular machines and configurations are kept in stock. Options like SUPER GRIND and Hot Black Oxide will add to these lead times. We
We purchase all of our steel plate professionally ground and certified by our material suppliers. Hobbyist class plates are blanchard ground and the professional class plates are finish ground. The blanchard grinding is +/-.0015" parallel over 12" and the finish grinding is certified parallel within +/-.0025" over 24". If you are having problems with getting
Our pricing is based on cost of materials and machining time. The TT1634C is made of 4140PH steel. This is a VERY tough steel. It is expensive, it is difficult to grind, and it is difficult to machine. The end result is a plate that wont strip threads, and the bores wont bell out. Awesome
