Ceramic cutters
A ceramic cutting device having a base, longitudinal guides mounted to the base, and a support movably mounted on the longitudinal guides. A cutting-wheel handle holder is pivotably mounted to the support. A cutting-wheel handle is mounted to the handle holder and the cutting wheel is mounted to the handle. An actuating lever is mounted in a threaded hole in the handle holder so as to immobilize the handle so that the handle can apply pressure on a ceramic piece to be cut via the cutting wheel. The cutting wheel handle has an outer periphery with at least three longitudinally extended rebates which have a geometry that reduces the frequency of vibration during scoring of the ceramic piece by the cutting-wheel. The handle further has at least one longitudinally extending planar surface for engaging with the actuating lever.
1. A ceramic cutting device, comprising:
a base;
longitudinal guides mounted to the base;
a support movably mounted on the longitudinal guides;
a cutting-wheel handle holder pivotably mounted to the support;
a cutting-wheel handle mounted in the handle holder and having a length;
a cutting wheel mounted on the handle; and
an actuating lever mounted in a threaded hole in the handle holder so as to immobilize the handle so that the handle applies pressure on a ceramic piece to be cut via the cutting-wheel, the cutting wheel handle having an outer periphery with at least three longitudinally extending rebates that extend over substantially the entire length of the cutting wheel handle, the rebates having a geometry so as to reduce a frequency of vibration during scoring of the ceramic piece by the cutting-wheel, the cutting-wheel handle further having at least one longitudinally extending planar surface for engaging the actuating lever.
2. The ceramic cutting device according to claim 1 , wherein the cutting-wheel handle holder forms a housing having a transverse section that corresponds to a transverse section of the cutting-wheel handle so as to provide maximum surface contact between the handle holder and the handle, and, together with an end of the actuating lever, a hyperstatic fixing of the cutting-wheel handle with the cutting-wheel handle holder.
