horizontal spindle rotary table surface grinder brands

Most other rotary table surface grinder manufacturers use conventional thrust roller bearings for their rotary table slide. Thrust roller bearings deliver inferior precision, as well as shorter service life due to their low resistance against wear and tear from prolonged use. As a result, grinders that use thrust roller bearings also require frequent repairs and replacements of the bearings.

As a superior alternative, our table slides use metal rings that are processed with our scraping techniques and fabricated with grooves for the lubricant oil. This technique delivers table surface rigidity against vibration to nearly 0 mm with sustained performance for an extended period, which reduces the need for regular maintenance.

Scraping technique is also applied to our box way of x-axis transfer slide to achieve superior parallelism and flatness of table surface. This differs from the LM-guide way for the x-axis that is widely used by other manufacturers. LM-guide ways have a transfer precision of roughly 0.005mm to 0.01mm on the grinder’s wheels and table and are unable to deliver high precision level. Moreover, the LM-guide requires frequent maintenance to adjust for the LM-guide’s loosened balls. By using our scraping techniques, LPR Global’s box way overcomes these shortcoming to deliver a <3㎛transfer precision of table and wheel and maintain high precision levels for an extended service life.

•Access to work table is unique, in that a greater proportion of the work table is opened for easier and safer work handling. Being a fixed centre table the initial accuracies are maintained for the entire life of the machine.

This series features the well proven program of surface grinders with rotary tables. These machines are particularly suitable for High precision surface grinding on thin parts of accuracy and circular parts where one piece is to be ground at a time flat or with a radial taper. Besides, in applications where batches of small parts are to be ground with a high degree of parallelism and high surface finish this type of machines is a better alternative to a reciprocating machine as production time will be much less. This is because the grinding wheel is in constant touch with the grinding pieces are higher and the work pieces work constantly in one direction only.

Machine shops that grind metal or alloy surfaces flat to remove the material or achieve a precise thickness now have “endless possibilities” to improve their precision as well as production speed and control with more advanced, automated units.

Today’s rotary surface grinders offer sophisticated sensors and controls that can reliably achieve tighter dimensional tolerances, flatness, parallelism, and surface finish. The equipment can be used to grind flat metals, alloys, and ceramics to precise dimensions before polishing.

Operator control over the process is unsurpassed with the new automated grinders. The user can enter the specific requirements, for example: 712 RPMs on the spindle, 22 RPMs on the table, with a down-feed rate of .003 inches per minute, with a certain dwell cycle. Essentially, the machine can be programmed to meet just about any requirement.

Compared to traditional grinding equipment with manual controls that require experienced machinists familiar with the nuances of each machine, these automated units consistently produce higher quality parts in less time. As a result, a growing number of machine shops are installing new grinders that can be operated by less experienced personnel while still achieving the desired results.

In machine shops that work with metals and alloys, factors such as thickness, parallelism, and surface condition are often dictated in the specifications. Grinding is also often utilized to remove significant amounts of material to bring a stock sheet or plate to precise dimensions.

To do this, machine shops primarily utilize surface grinders with a reciprocating table and a horizontal spindle that turns the grinding wheel, but the process is slow.

“Reciprocating table grinders are precise, but the material removal rate is slow and multiple passes are required,” says Erik Lawson, engineering manager at Winona, MN-based DCM Tech, a designer and builder of industrial rotary surface grinders.

Older rotary surface grinders are another option but can be problematic in the hands of less experienced operators. With limited control of spindle speeds as well as manual controls, the older equipment requires sophisticated operators that can factor in complex calculations. Considerable expertise and experience are required, which can be a challenge as skilled operators retire.

In modern vertical spindle, rotary table surface grinders, the table rotates with the workpiece held firmly in place underneath a vertical spindle. The grinding is not performed by the peripheral edge of the wheel, but by the entire diameter of the abrasive surface, which facilitates grinding performance and consistency.

“With rotary table surface grinders, the entire part passes through the wheel, which is more efficient than reciprocating table grinders that may have workpieces wider than the grinding wheel,” said Lawson.

Today, surface grinders are designed with sensors and controls that automatically maintain tight tolerances, removing material down to within one ten-thousandth of an inch of the final thickness. Digital technology allows for an interface with easy-to-use touchscreen controls. When combined with automation, surface grinder operators are no longer required to be trained individuals.

For example, rotary units such as DCM Tech’s IG 280 SD, with a 24” variable speed table and 20HP variable speed grinding spindle motor, make it possible for virtually anyone to successfully operate a unit. This model automates the initial contact between the abrasive wheel and part, which typically had to be finessed by the operator. With this updated option, advanced sensor technology detects vibration and can automatically fine-tune not only the pressure of the spindle motor but how quickly it moves the wheel down onto the part. When the machine senses the abrasive wheel has contacted the part, it begins the grind cycle automatically.

“Automatic part detection eliminates the need for the operator to do time-consuming, error prone ‘manual touch offs where they would manually feed the [grinding] machine until it just touches the surface of the part before backing off and restarting it,” said Lawson.

With regard to production efficiency, the advanced rotary surface grinders are also much faster than reciprocating grinders because the units can get much closer to the required precise dimensions before any finishing steps. This capability can reduce or even eliminate some lapping and polishing steps.

With a conventional surface grinder, if a stock with standard thickness needs to be ground down, an operator would stop short of the required removal and leave an unpolished surface. Using another machine was often required to remove the remaining material but this can take excessive time and labor.

“A rotary surface grinder will usually finish the work of a reciprocating grinder in a fraction of the time. For the manufacture of carbide blocks, one OEM was able to document a 14X improvement in cycle time by replacing a reciprocating grinder with a DCM rotary surface grinder,” said Lawson.

The grinder can also be programmed to take corrective actions on subsequent passes if the workpiece is a little off on the first pass. There is no need to pick up the workpiece and measure it after every move as with older machines.

According to Lawson, the automation provided by advanced rotary grinders allows operators to set up the machine and then attend to other tasks. The machine does not need to be constantly monitored because it has built-in load monitoring.

“Load monitoring allows the user to set limits so the machine does not overtax the part being ground or overload the spindle. If something a little unusual happens it can continue without interruption or shutting down,” said Lawson.

As metal and alloy grinding tolerances become stricter and production requirements more demanding, machine shops that take advantage of advanced, automated rotary surface grinders will outperform rivals even as experienced operators retire.

“With automated rotary surface grinders, a machinist can be trained to be proficient at operating the equipment by lunch on the first day. It just takes a few hours of training, not decades of experience as with older machines,” said Lawson. He added that systems incorporating full automation are now being developed that will use a robot to load, set up, and run parts without an operator nearby.
