Newly Launch Hydrostatic Grinding machine from Grintimate.

Grintimate Precision Co., Ltd is specialized in manufacturing super high precision gring machine – Grintimate own the advanced hydrostatic technology, the newly develped hydrostatic spindle, hydrostatic saddle, and hydrostatic turn table provides super high precision, high quality and low – wear , eco-friendly grinding machines.

Early they launched the only one (wide forming wheel Cylindrical grinding machine in Asia CTS-100, with the outstanding feature to carry a wide formaing wheel up to 300 mm width and able to take up to 15 steps grinding in one cycle thanks to their unique conversational control.

Tricia Tsai, vice president of Grintimate said that Grintimate have enormous R&D power, the new R&D had never stop to reaserch and develp more choices for its customer, in 2019 they launched a complete hydrostatic surface grinder – the spindle, saddle and rotary table all apply hydrostatic technology. And the model name for such machine is GRC. This machine is focus on providing solution for semi-conductor industries on grinding ceramic tooling, sic, quartz, and so on special materials.

The grinding efficiency is 200% better than traditional reciprocating surface grinder. And because the hudrostatic spindle and table are highly regid, high damping and on-stick slip feature, the spindle and table rotating accuracy is below 1 Um, loading capacity up to incredible 10,000kg, it is also a highly stable and long life to prevent high cost maintence and repair.

The cover designed as cylindrical provide the best efficiency for oil-mist suction and recycling. Touch screen on either Fanuc or Mitsubishi screen and conversational control fufill the visualization operation for the operator, the operator can quickly familiar with the table speed, enable convex/Concave shape grinding.

Together with computer compensation and sub-micro feeding capability, one can directly input the result after machining. This gives the exotic material (combine two or more material in one)a great hand to assist for developement and cost saving.

Eco-Friendly, super high precision grinder from Grintimate.

With advanced hydrostatic technology, Succeefully and individually develp Hydrostatic spindle, hydrostatic turn table and hydrostatic saddle, Grintimate stands on a firm ground in Taiwan’s Machine Tool industry.

To provide the customer a high accuracy, high quality, eco-friendly super precision grinding machine, Grintimate can provide customer the customized machine for special grinding need.

CTS-100 is the latest Gritimate’s product, carry a max. 300 mm dia forming wheel, together with its conversational controller, one can complete up to 15 steps of grinding job, this model thus won the 2020 Taiwan excellence award.

According to Tricia Tsai, deputy president of Grintimate, Gritimate owns the high abiliy of R&D team, the Model GRC series gain a lot of positive feedback from customers.

Stamdard hydrostatic spindle and turn table carried high regidity, high damping and non-stick flip saddle, eable the accuracy of spindle and table rotation within 1UM. While loading capacity reach 10 metric ton, besides, Y /Z axes applied German made liner guide and ball screw, combine wih heidenhain Digital readout together withThe high damping spindle to rech super high accuracy for the entire machine. Cope with Mitsubishi/Fanuc control with their own develped conversational function, achieved visualization operation in order to adjust program for better efficiency. Modulized design for machine combine with high standard components to achieved the accuracy requirement.

GRC rotary table surface grindershown in SEMICON Taiwan

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
