Description

Technical Field

[0001] The invention relates to a die and a forming process for forming a large-size three-hole ceramic guide rail, belonging to the technical field of ceramic forming. Background Art

[0002] Ultra-high-precision coordinate measuring machines (CMMs), with their high accuracy, long travel range, and stability, are ideal for measuring large workpieces in industries such as aviation, automotive, and energy. Alumina ceramic guideways are a high-performance industrial guideway material, widely used in precision machinery, CMM, semiconductor equipment, and medical devices due to their excellent physical and chemical properties. Currently, large, high-precision CMMs typically require a lightweight X-axis design, necessitating the use of large-sized porous alumina ceramic guideways to minimize thermal deformation.

[0003] However, large-size three-hole alumina ceramic guide rails have practical problems such as difficulty in forming, heavy weight, low pass rate, and easy cracking. At present, there is no method on the market to achieve integrated forming of three-hole ceramic guide rails, and most of them use splicing structures, which leads to problems such as cumbersome production process.

[0019] S7. Remove the hemp rope, check the appearance and size of the green billet, make relevant records after confirming that there is no abnormality, and transfer it to the turnover area for use.

[0020] Preferably, in step S3, the balancing platform is leveled by adjusting the height of the bolts at the bottom of the balancing platform, and a spirit level is used for verification to adjust the balancing platform to a horizontal state.

[0021] Preferably, in step S41, ensuring that the secondary mold sleeve and the balance platform remain vertical includes the following steps:

[0022] Place a laser line-laying instrument on the front and side of the auxiliary mold sleeve so that the rays of the two laser line-laying instruments coincide with the four vertical side ridges of the auxiliary mold sleeve, which can ensure that the auxiliary mold sleeve and the balance platform remain vertical.
