Outstanding process power and throughput has reached a new dimension with the AC 700 HT Fine Grinding System – accompanied by numerous ready-to-go processes and economical automation solutions your cost per workpieces can now reach their all time low but keep the precision you already appreciate from our other Fine Grinding Systems of the microLine® range.
PETER WOLTERS research team has found the optimal power solution for your grinding challenge by optimizing the interaction of software, coolant supply temperature management, pressures and power of the drives. The result is extremely high cut rates that make you forget about any pre-grinding you had to do in addition in the past. Just combine stock removal and finishing into one, economical system.

The Lapmaster line of dual side planetary fine grinding machines are specially designed and built to withstand extreme conditions within a production environment while requiring minimal maintenance. These units are available with fine grinding platens from 20" up to 55" in diameter, and are specially configured for each application. Depending upon the application, these machines utilize fixed abrasive diamond or CBN suspended in resin, metal, and vitrified bonds to grind a wide range of materials to very tight specifications.
The Lapmaster DSG series of twin wheel grinding machines are driven by three, variable speed motors for maximum process control flexibility. All three rotating machine components, the sun gear, top plate, and bottom plate, are independently controlled. Process down pressure requirements are pneumatically regulated and continuously monitored by a load cell.

With SATURN double-disc surface grinding, two vertical grinding wheels simultaneously grind the workpiece on its parallel outer surfaces. The grinding wheels are set against each other at a slightly conical angle, so that as it passes from top to bottom, the workpiece retains its final dimension only in the bottom section of the grinding path. Because the workpieces are fed vertically between the grinding wheels, the bearing weight of the workpiece does not affect the grinding result. What’s more, the
coolant can simply drain downwards together with the removed material. The SATURN range comprises three
different machining processes:
- Rotation process
- Parallel grinding with linear through-feed
- Pendulum grinding

The VERTICAL AXIS version is particularly suited for grinding thin parts and, the version with interpolated feed system, for grinding critical materials such as tungsten carbide or ceramic using diamond grinding wheels.
INTERPOLATED FEED:
It is the latest and most exclusive system, designed by VIOTTO for grinding parts in tungsten carbide, cermet and ceramic, even of large size.
This is obtained by the interpolation of 3 axes, controlled by the CNC, which perform the following movements:
rotation of the workpiece to carry it between the wheels (AXIS 1)
oscillaton of the workpiece between the wheels (AXIS 2)
plunge cycle of the top wheel on the workpiece (AXIS 3)
In this feed system the grinding wheels are set perfectly parallel to obtain still closer tolerances for flatness and parallelism.

Twiflex VMS-DP Mill Brake Stand. One of four units supplied to Metso Minerals for use at the Telfer Mine, Australia. The two units combined produce 16Million NM of brake torque!
The VMS-DP Mill Brake brakes will be installed on SAG (semi-autogenous grinding) Mills used for the extraction of copper and gold from virgin rock. Fresh ore is continually conveyed into the mills that are pre-charged with various sizes of steel balls, crushing the rock when the mill rotates. The ore is crushed until small enough to pass through the openings in the discharge grates. The material is then conveyed to a secondary Ball Mill for fine grinding.
The brakes which are used for emer-gency stopping and holding have been designed specifically for this application and will be the largest that Twiflex has ever manufactured. The VMS-DP caliper is approximately the size of an office desk and weighs approximately 2 metric tonnes. Each brake produces 768kN of braking force, 4-6 calipers provide braking to each mill flange.
