台湾のTaiwan Excellence賞を受けたロータリー平面研削盤 - SEMICON Taiwanに出展

Grintimate Precision Co., Ltd is the manufacturer of super high Precision grinding machines. Owns unique hydrostatic technology, they applied such technology on the spindle of grinding wheel, saddle of machine and turning table on machine, in order to produce highly accurate, high quality, lower wear and eco-friendly machine.

Earlier they launch the unique wide width grinding wheel Hydrostatic cylindrical grinding machine CTS-100,featuring carrying wide forming grinding wheel up to 300mm dia. and is able to cope with conversational screen to complete up to 15 steps of grinding in one cycle. CTS -100 thus awarded Taiwan Excellence.

According to Tricia Tsai, the vice president of Grintimate, they owned massive R&D power and never stop the research & development In order to provide more kind of super high precision grinding machine Grintimate launch a new model GRC series, a horizontal turn table surface grinder in 2019. This machine is specially designed to grind hard and fragile high precision components. Take, semi-conductor Industry for example. Ceramic substrate, silica, quartz etc GRC productivity is more than double compare with traditional reciprocating surface grinder,and the high rigidity spindle and turn table, high damping and non-stick slip features on the hydrostatic components capable for high gravity eccentric machining,the rotating accuracy on spindle and table is within 1µm,table loading capacity is up to 10,000KG,the machine also ensure high steadiness and longer life. In all it is great saving on expensive maintenance.

The cylindrical design for GRC cover ensure the high suction and recycle for oil mist during machining. Indeed a eco-friendly design.

The controller can choose either Mitsubish orFanuc touch screen panel. Combine with HMI(Human Machine Interface) and conversation feature, it fist on visual operation, very easy to operate and learn. Unlike traditional surface grinder require to adjust the table. GRC is easily to conduct special cutting such as convex or concave shape. Precise calculation and compensation on axes backlash enable the linear guide way to perform sub-micron feeding. This function can input the grinding result and this function is great assist on time saving on material combine two or more exotic material, particularly common in Semi-Conductor industry.

Despite of overcome the challenge of vibration during cutting. On the Structure of GRC not only considerate to reduce the vibration cause by mechanic component during machining. The design of base and column is also important, the double column design is much rugged than single column. The triangular design for spindle is best for resistance to the reaction force during grinding. This is an identical differences compare to other Taiwanese grinding machine.

Besides, the biggest advantage is the Y axis guide way is designed at the same height as the rotary table. This greatly improve the dynamic accuracy when the Y-axis movement. It is also an ergonomic design to take the operator’s convenience into consideration. The simple table adjustment design enable the operator fast adjustment on table angle when needed, the guideway is designed away from cutting polluted area in order to prolong the life span of guide ways. Ther armory cover design enhanced the safety when applying oil mist and different from bellow shape cover, it is uneasy to be broken, the Y&Z axes apply direct mounting on motor to reduce tolerance during assemble and in cease accuracy
