ND Camshaft Inspection

marposs — Sun, 22 Jun 2008 22:17:58 +0000

Manual Gauging Station for Multidimensional Inspection of Conrods

A) Problem Description

Camshafts for automobile engines are manufactured using a variety of methods.They can cause a variety of quality defects, such as:

* porosity

* hardness cracks

* casting shrinkage, cavities and holes

* missing material

Subsequent grinding can also cause cracks or grinding burns (soft spots). They are caused by variations during grinding operations such as changes in grinding speed, changes in grinding wheel/workpiece position and by the effects of the coolant used.

In the past, attempts to automate test procedures have often failed.

B) Solution

Complex geometry’s such as camlobes can now be easily tested with standard Marposs N.D. probes. The Marposs N.D. inspection method is based on the Eddy Current technology. It is the only method capable of performing N.D. inspections automatically. For this reason, it can be easily installed into a production line for 100% inspection.

The traditional testing procedure, which is usually performed with magnetic powder and/or human evaluation, can be now reduced in terms of inspection time and overall cost.

Cracks as small as 100 microns in depth can be detected, dependent upon the surface finishing and material homogeneity

M63 Measuring System

marposs — Tue, 20 May 2008 15:35:42 +0000

Manual gauging station for inspection of ring-like components (bushings)

The M63 bench is an innovative measuring system with the following strengths: simple and efficient in design, compact and robust.

The bench gauge is dedicated to the final or interoperational inspection of a single bushing type part (vertical axis, radial symmetry and weighing less than 15 Kg/33 lb).

The part is manually loaded and referred on a nosepiece or a descending pivoting arm.

The most recent Marposs measuring transmissions belonging to the AMA line are utilized in the gauge design (made with non-magnetic stainless steel) and with Red Crown pencil probes. These measuring components are mounted to a counterplate fixed to the part support plate by three columns.

This mechanical solution completely isolates the measuring structure from the weight of the part, assuring the highest metrological performances.

If required by the application, the measuring transmissions can be provided with pneumatic retraction. The actuation of the rear measuring group can be manual or pneumatic.

The new M63 bench replaces the Marposs Universal Quick Set bench when no retooling is needed and is provided with guarding for the rear measuring group.

The gauge system can be provided with either static or dynamic capabilities for dimensional and geometric inspection of I.D.’s and/or O.D.’s.

Vertical Station for Manual Inspection of Shafts – M67

marposs — Mon, 05 May 2008 18:08:58 +0000

The M67 bench is an innovative measuring system with the following strengths: simplicity and efficient in design, compact and robust.

Its bracketry and guarding are manufactured using Laser Cutting technology which can be easily integrated with CAD systems. This reduces both preparation times and costs for manufacturing of individual details.

The bench is dedicated to the final or interoperational inspection of a single part type weighing less than 6 Kg.

The measuring components are realized with the most recent Marposs measuring transmissions belonging to the AMA line (made in non-magnetic stainless steel) and with Red Crown pencil probes.

The workpiece is manually loaded in the vertical position and referred between centers that are either fixed or motorized.

Vertical Bench for Shaft Inspection M57V

marposs — Thu, 20 Mar 2008 07:49:34 +0000

The M57V bench is an innovative measuring system which offers simplicity through the efficiency of its design, as well as being compact and robust.

The vertical solution provides a much smaller foot print which takes up a limited amount of surface space as compared to the horizontal solution. In addition, vertical loading of the part eliminates part and structural deformation, as well as any bending in the reference centers and helps part dragging in dynamic applications.

The bench, engineered for crankshafts weighing more than 6 Kg, can also check camshafts, gear shafts, rotors and axle shafts.

The measuring components are comprised of the Marposs measuring transmission devices belonging to the AMA line (made of non-magnetic stainless steel) and Red Crown pencil probes. Other cell types can be used in special applications. The bench gauge is dedicated to the inter-operational inspection of a single part type after end face milling, turning, pin bearing milling and grinding. The work piece is loaded manually or by a manual gantry between centers in the vertical position. The centers are either fixed (static measurement) or motorized (dynamic measurement) and the measuring stations are brought onto the part by manual pivoting arms.

M19 Gauge Plug for Transfer Lines

marposs — Thu, 12 Jul 2007 22:20:13 +0000

Marposs M19 plug is:

designed to perform two internal diameter measurements in the same section of the bore at 90¬? to each other utilized after turning and grinding operations on transfer machines, special purpose machines and post-process gauging stations

typical for the check of connecting rods, cylinder bores and when measurement for ovality is required

The plug guarantees reliability and increased productivity of the process by automation of the process itself inclusive of the part measurement and closed loop feedback to the machine tool (compensation of tool wear, improvement of overall machining time and scrap reduction).
Measurements are performed by use of four Marposs measuring cells, each provided with one LVDT transducer.
The plug uses a body with fixed nosepiece. In order to protect it from potential collision due to part mis-positioning or part overstock conditions, the plug requires mounting to rigid recoiling devices.
In the diameter range from 22 to 80 mm the gauge plug is provided with cleaning air nozzles in the measuring section while in the diameter range from 16 to 22 mm the cleaning air flow is offset and located in proximity of the gauge fingers (the air inlet is always at 180¬? with respect to the junction box).
It can be connected to E9066N electronic unit for complex applications or applications for which statistical analysis is required and to E3 family electronic units for simple applications.
Side-by-side assembled on the machine, the gauge plugs can measure bores having minimum center distance of 71 mm.

Automatic Measuring Machine – M110

marposs — Sun, 27 May 2007 08:17:24 +0000

Automatic Measuring Machine for Inspection of Shafts (Crankshafts, Camshafts, Gear Shafts)

The M110 machine is an automated inspection system, developed to measure all dimensional and geometric parameters for shaft-like part configurations.
It is based on a modular construction and designed using the most advanced engineering criteria. The result is a reliable and accurate inspection instrument.

This gauging machine does not need to be housed in a controlled environment, thanks to it robustness. It operates in a normal production area and is suitable either for inter-operational and/or final inspections.

Besides gauging, functions like non destructive (ND) testing, marking and parts segregation may be easily integrated to the basic machine.

The M110 machine includes all the systems necessary to load, locate and rotate the parts to be inspected; no manual operations are required. This allows a completely automatic measuring cycle, including part load and unload.

The capability of high speed performance along with the application in shop floor conditions, make it possible to check all the conventional parameters on 100% of the manufactured parts, guaranteeing and certifying the overall quality of the production.

This equipment is used along with the E9066N FLAT PANEL and/or the E70s electronic unit. Follow the link to know more: Automatic Measuring Machine for Inspection of Shafts
