Vibration control in Precision Centerless Grinders

Vibra Mountings -Anti Vibration Mounts

Centerless grinders are one of the most common tools used in manufacturing. These machines are used to remove material at a steady yet slow pace through the process of grinding. Centerless Grinding is equipped to grind a wide variety of studs, pins, bolts, screws, bushings, and other parts from a full range of materials. These machines are commonly found in manufacturing settings in aircraft, aerospace, defence, hardware, electronics, automotive, marine & medical industries.

Centerless Grinder On Dynemech Vibra Mounts

It’s the relationship among these three basic components—grinding wheel, regulating wheel and work blade—that makes the difference between a successful centerless grinding application and one that gives headaches and bad parts. But, it is the same interaction that gives rise to undesirable vibrations leading to uneven surface finish, problem of chatter and rejection of job lots and overall loss of production efficiency. Unbalance in spindle-collet combine, grinding wheels, motors , bearings ,presence of outside vibration all affect the precision grinding process.  The use of centerless grinding has now a days become imperative in shops involved in high volume production runs.

Grinders -Vibration Isolation

Forced vibration from machine rotating elements and self-excited vibration produce a relative radial movement between the wheel and work piece during grinding and the wheel and diamond during dressing, causing errors in work piece finish and form. By controlling vibration produced during the grinding and wheel dressing operations a measure of expected work piece accuracy and quality can be obtained.

Anti Vibration Pads For CNC Grinders

Over the years, Dynemech has successfully isolated all kinds of passive vibration ie. vibrations coming to the centerless grinder from other impact and rotating machines of the shop floor and/or from other nearby sources. Our anti vibration solutions provide a unique combination of value, precision, productivity and practical usability. They also provide protection from vibrations transmission from the machines to nearby sensitive equipments and machines, to suspended floors, walls and buildings.

Centerless Grinding Machinery Mounts

Dynemech has engineered different anti vibration solutions for centerless grinding machine depending upon the environments they are being installed in. Some of the scenarios are:

ANTI VIBRATION PADS FOR HONING APPLICATIONS

Honing Machine Installed On Dynemech Wedge Mounts, Series DB

Honing is a metal removal process used after casting, sintering, drilling, boring, or reaming to obtain precise bore dimension, geometry (cylindricity, roundness, straightness, and taper) and surface finish. Though with the development of precision machining and ultra precision machining technology, machining precision demands to achieve sub micron level have increased, chatter is still a problem during grinding which affects surface quality directly and reduces productivity. It is more serious in high precision honing process in which a small vibration would make the size or surface roughness of proposed part poor, leading to rejections.

In general honing the movement of the honing head is the synthesis of rotation movement and reciprocating movement whose trajectory is a spiral curve with up and down movement in close tolerances. With them numerous mechanical structure, rotating and revolving parts with different mechanisms working in compression, stress and torsion in a machine, lead to arousal of vibrations during the honing process.

Vibrations may also travel from external environment to Honing Machines disturbing surface finish and accuracy of the job. Dynemech low natural frequency isolators damps most of the incoming vibrations and allows smooth operation.

Machinery Mounts For Honing Machines

Vibration Reduction mounts

Vibration isolation is imposed to separate a dynamical system from its environment by means of isolator/pad/mounts which has a considerably different natural frequency, compared to the forcing frequency of the applied force.

The natural frequency is specific for each system and is directly proportional to the stiffness and inversely proportional to the mass. Thus, greater the mass and lesser the rigidity, the lower the frequency will be. To reduce the rigidity of the system as much as possible, we need to increase its elasticity. The natural frequency is in inverse proportion to the static deflection under the weight due to gravity. So, by creating a phase difference of vibration frequency, both passive and vibration control can be achieved in honing applications.

Vibration Reduction Solutions For Pressure Die Casting Machines

Dynemech Anti Vibration Pads for Pressure Die Casting Machines

Pressure diecasting is a process in which molten metal is introduced into a metal mould or “die”, and is subjected to pressure in order that it shall conform to the exact shape of the mould impression or “die cavity”. 

Die casting has progressed over the last fifty years from relatively small parts made from lower melting metals and alloys such as zinc, to today’s casting of very large parts, such as engine blocks.

As die casting conditions grow more severe in temperature, pressure and increased part size, increase movement-clamping arrangements the need arises for vibration isolators to enhance the die casting process, by providing precision levelling, alignment and vibration control.

No Vibration Transmission-Turret Punch Presses

DYNEMECH-PUNCH-PRESS-MOUNTS

Precision metal fabricators and sheet metal components manufacturers depend on Dynemech vibration isolation mounts for isolating their highly accurate CNC Turret Punch Presses from vibrations.

 

Vibration-Free-Shop-Floor

Recognizing how important it is to provide fast, flexible responses to customer demands, many sheet metal pressed and fabricated components manufacturers are using the latest CNC Manufacturing machines for the same. But, increased feed and cutting rates also leads to increased vibration and noise. And thus, if these vibrations hamper production accuracies or increase maintenance issues and production cost all productivity gains are offset.

Turret-Punch-Press-on-Dynemech-Wedge-Mounts

CNC turret punching is a cost effective method for cutting sheet steel in moderate to long runs, rapidly integrate processes to eliminate post operations. It has vast tooling potential for the increased versatility translating into the ability to produce variety of components without re-tooling.  CNC turret punch press is widely used in many varieties of sheet metal processing industries , such as Automobile , air conditioning & refrigeration mfg., textile & pharma machinery mfg., communications, electronics ,computers, elevators , air conditioning, kitchen utensils , mechanical housings processing industries.

Dynemech anti vibration pads ensure that even at maximum tonnage, vibrations are not carried over to the table delivering increased precision and high quality parts, not to mention improved tooling life. The electronics and laser controls is isolated from punching vibration to help maintain beam integrity and cut quality.

In impact generating machines like turret punches anti vibration flexible pads convert low duration of impact in to an impulse of a longer period. Longer the natural vibration period of the machine, isolator & foundation system, lower will be the vibration transmissibility. Thus, vibration isolators produce a time delay and act as a source of temporary energy storage and to some extent as a energy damper which evens out the disturbing vibration in each oscillation. The elastic (potential) energy of the dampers transforms into motion (kinetic) energy of the machine and back into potential energy of the isolator, and so on. In reality, there are always some losses of the energy (usually, into thermal energy) due to friction, imperfections etc. As a result, the total energy is gradually decreasing (dissipated), thus diminishing the intensity (amplitude) of the isolated system. i.e. vibration damping.

Dynemech precision wedge mounts also provide flexible machinery installation options along with mitigation of vibration and noise transmission from metal cutting machines to other machines in the shop floor. To improve the vibration and noise isolation effect, wedge mounts are usually combined with Di insulation plate having Coefficient of friction 0.8 and natural frequency range of 25 Hz -7 Hz depending on the load of the machine. These sturdy machine vibration pads limit the swift horizontal jerks caused by rapid material movement besides vibration transmission and vibration isolation.

Injection Moulding Machine Mounts

Vibration and Shock Control in Injection Moulding Machines

Dynemech Anti Vibration Machinery Mounts

Active Vibration Control in Injection Moulding Machine on Machine Mounts

Dynemech's Injection Molding Machine Mounts provide optimum leveling and alignment of the machines within minutes, without anchoring either the machine or machine mounts to the floor. Dynemech Insulation Sheets are designed especially for injection molding and die casting machines. These vibration insulation sheets dampen both vertical and horizontal impacts found in reciprocating machines. In addition, each vibration isolation pad is engineered to possess an exceptionally high coefficient of friction that also prevents machine "walking".

An Injection molding machine, also known as an injection press, is a machine for manufacturing plastic products by the injection molding process. Injection molding machines can fasten the molds in either a horizontal or vertical position. The majority of machines are horizontally oriented, but vertical machines are used in some niche applications such as insert molding, allowing the machine to take advantage of gravity. The operations in Injection Moulding Machines produce high impact forces. These forces travel through the machine frame into the foundation. The foundation produces a rebound force equal to the impact force and this travels inside the machine. The magnitude of the vibration within the Injection moulding machine is lower when using Anti-vibration machine mounts. Bolting the machine rigidly to a foundation subjects it to more vibration and impact force. Vibration isolators or machine mounts are cushions that transform a sudden shock pulse into a decaying series of longer duration forces. 

Injection moulding is a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. Material is fed into a heated barrel, mixed, and forced into a mould cavity where it cools and hardens to the configuration of the cavity. Injection moulding is widely used for manufacturing a variety of parts, from the smallest component to entire body panels of cars. To ensure higher productivity, better control, faster injection rates or better quality finished parts, Numerous automobile part manufacturers, Plastics makers, Toys makers, Aerospace, Manufacturers of Plastic Capsules and Health Related Equipments, Packing and Plumbing Equipments manufacturers turn to Dynemech range of flexible vibration control solutions ranging from DYNEMECH INSULATION PLATES, Die Cushion Pads, Wedge Mounts, Screw Support Mounts, Economical Mac Level Series DML, Series DLM/DLMS which help us to install machines even on uneven surfaces and the recently developed DLK series.
