High Quality in your Hands

Over a number of years, specific designs were realized depending on machine type or the part to be ground. In the late 1990′s Marposs rationalised and engineered the Unimar which is a truly unique gauge head combining high precision with versatility.

Thousands of Unimar gauge systems have already been installed worldwide by manufacturers of all types of grinding machines with exceptional results, these being used in many industrial sectors, including the automotive, bearing, compressors, injectors, hydraulic, and electrical appliance industries.

To suit the current and future trend for smaller grinding machines, Marposs has now introduced the NanoUnimar, another innovative design, evolving from the successful Unimar range.

NanoUnimar has small physical dimensions, however it pays large dividends in term of cost and performance ratios. Its sub-micron accuracy and stability are, with its compact size, the main features in providing a gauge solution when space is restricted and micro components are being ground.

NanoUnimar can be used with the full range of Marposs electronic units, including the P7 with its cycle display and machine control via its screen.

Alternatively it can be directly connected to the grinding machine’s PC based CNC using the Marposs Human Interface Software (MHIS), making efficient use of an existing resource.

In spite of its size NanoUnimar’s design provides reliability and precision whilst in the harsh grinding environment and ensures that modern process tolerances can be achieved.

The measuring head and its introduction slide, which can be either pneumatically or hydraulically applied, are the smallest available on the market and consequently provide a gauging solution when table space is restricted and micro components are being ground.

The MicroAlsar gauge head including its cable and connector ensures the integrity of the measuring signal providing guaranteed performance and reliability in the most hostile conditions encountered in the industrial environment.

Unimar S – High Precision Solution for Match Grinding Applications

marposs — Fri, 30 May 2008 14:38:05 +0000

High Precision Solution for Match Grinding Applications

The latest automobiles with diesel engines have performance, excellent fuel efficiency, and low emissions. With electronic data management of the engine to optimize the combustion several critical parts require a manufacturing process to achieve a tolerance better than 2 microns.

The measuring gauges for these processes must have a total accuracy of some nanometers. This precision has already been reached in the metrology laboratory with temperature stability, but it is unusual to be applied to machine tools on the shop floor. A use of this special gauge is the grinding process of components for the diesel engine injection and hydraulic spools where matching tolerances are often of few microns

Electronic Measuring System for Process Control on Grinders and Other Machine Tools

Part measurement during the machining process allows parameters that affect part quality such as size, shape, surface quality, cycle time and tool wear to be monitored. The change in the measurement during grinding (stock removal speed) is compared with grinding wheel feed rate values and if the check limits are exceeded the P7ME electronic system automatically modifies the machining cycle to optimise the entire process. The machine tool‚Äôs natural deviation from the required value can be monitored using post process sample measurements which, with suitable statistical processing, supply the data for automatic tool compensation.

Grinding Line: MHIS (Marposs Human Interface SW)

Software packages for integration of Marposs Human Interface inside the machine tool ‘s pc /cnc

The ever increasing possibility of multitasking operation for the CNCs which control grinding machines and the increase in their graphics capacities has allowed Manufacturers to design and develop the user interface to be increasingly ergonomic and specific for machine operators.

As a result, they can view process parameters and at the same time interact with them without compromising machining cycle performance.

The same type of operation is also required of the interface for accessory and control functions (in process measure, grinding wheel balancing, etc.) which are normally performed by installing specific apparatuses on the machine. A growing number of grinding machine manufacturer need and want to create an optimised user interface for their machines, an interface shared by the various functions with the aim of making it simpler for end users.

Another aim is to reduce the space occupied on the Machine Panel by the front panels of the various apparatuses.

Here the software to satisfy the need for INTEGRATION of the user interface as regards the part relative to control functions such as:

* in process measurement

* grinding whell balancing

* analysis using acoustic sensors

Marposs proposes MHIS, a software developed for the Windows?Ç¬Æ 2000/NT/XP environment, able to operate in the machine PC /CNC.

MHIS activates the connection between the machine PC/CNC and the P5/P7 using an RS 232 interface or via Ethernet.

MHIS is also supplied as a software Component (OCX).

Therefore, it can be integrated in the User Interface designed by the machine Manufacturer using Microsoft COM environment rules.

An OPC server is also available. Thanks to the Client – Sever architecture this allows two or more User programs simultaneously active in the PC/CNC to share the data which arrives from the Gauge.

Flange and Spindle Type Balancing Heads – Grinding Line

marposs — Wed, 23 May 2007 21:05:09 +0000

The Marposs balancer is an electromechanical grinding wheel balancing system for grinding machines which gives significantly improved part surface quality and increased machine life and productivity.

By measuring the vibrations caused by an unbalanced grinding wheel and suitably moving weights flanged to the outside of the grinding wheel (FT balancers) or inserted in the spindle (ST balancers), the system definitively eliminates the need to manually pre-balance new grinding wheels, whether made of conventional agglomerate, CBN or diamond, restoring optimum dynamic conditions for the entire life of the grinding wheel.

The wide range of balancing systems can be applied to most grinding machines for exteriors, grinding without centres, grinding for tables, flexible and special grinding, solving the most diverse application problems.

Increased productivity and reduced maintenance costs are key elements of an economic process. The optimum solution is real-time control of events not belonging to part machining or machine conditions. Controlling events such as the grinding wheel – part, grinding wheel – dresser approach speeds and dressing depth of the machine, increases the productivity. The real-time control of machine conditions eliminates the unexpected causes of machine stoppages, allowing planned maintenance which is synonymous with efficient and astute use of systems.

Marposs makes available, in this control sector, a package of solutions/sensors for the control of acoustic emissions, vibrations and other parameters which allow most types of grinder to be monitored; providing solutions able to satisfy the requirements of an individual application with the most complete integration.
