1. We have been for years supplying our T-slotted box cubes worldwide to customers in the USA, Europe, South Asia, the Middle East, Africa, Russia, etc. These cast iron cubes are used as a workholding device to clamp and hold workpieces in the vertical position and as a vertical reference for inspection and tooling purposes in workshop machining processes such as shaping, planing, boring, milling, grinding and drilling, etc. They are also used to clamp motors, engines, transmissions etc. to carry out the assembly, tests, or inspections. Especially they are widely used to clamp workpieces on horizontal boring mills or drilling presses. With its multiple clamping surfaces, the box cube can clamp multiple workpieces on its different clamping surfaces, reducing the time spent on setting up of workpieces;
2. The types of cubes are available as being T-slotted, elongated-hole-slotted and tapped with threaded holes. The designs of these cubes are always customized as per their actual applications. They can be designed to have from one to six clamping surfaces. Upon inquiries, we will submit our customers the drawings and other technical proposals for their evaluations;
3. The cubes are made of close-grained and stress relieved gray cast iron GG-20, GG-25 or GG-30 upon buyer's request. In some cases casting steel can be used to build these cubes on request;
4. Cored and ribbed construction, twice annealing heat treatments at a temperature in the range of 600-700° C (the 1st annealing is done right after casting, the 2ND annealing is done right after the rough machining on the cube) and the following aging treatment are adopted on the angle plate to relieve the stress, ensure high stability and maintain its accuracy free from distortion;
5. Hardness of the clamping surfaces on the cube is in the range of HB160-240 and the surface flatness accuracy is available as Grade I, II or III as per DIN 876 Specifications;
6. T-slots, threaded holes are made as per customers requirements on these cubes;
7. Cubes with sizes above 300mm are webbed to ensure rigidity;
8. Traceable calibration certificates are provided along with the cubes;
9. Sizes of cubes are as per customer's request. Any sizes can be provided, including very large heavy duty cubes used as workholding device for floor type milling and boring machines.
