Waterless Cleaning and Surface Pre-treatment for Parts Prior to Painting

Cleaning and surface preparation prior to painting, coating, varnishing, bonding and welding is of critical importance in a wide range of industries. Manufacturers have unwanted contaminants on the surface of the part that must be removed prior to painting, coating and varnishing. Common surface preparation defects include dust, residues, particles, mold release agents, and other contaminants. The traditional surface pre-treatment process technologies are aqueous-based cleaning, manual solvent hand wipe operations, and air blow systems.

Aqueous-based cleaning systems require a large footprint and large quantities of water and detergents, while requiring a large electric energy demand and wastewater handling system. Manual hand wipe systems demand a trained workforce using solvent dipped rags which yields inconsistent cleaning results. Air blow systems do not have the cleaning force to remove heavier dusts and contaminants from the surface, affecting the bond adhesion.

CO2 spray cleaning systems provide cost effective no-touch cleaning technology that can be dropped into many production lines with a fraction of the footprint. Because the primary cleaning agent is solid CO2 particles, or snow, which sublimes upon contact with the surface, there is no cleaning agent residues to manage. The cleaning spray can be combined with an integrated solvent injection to modify the chemistry of the cleaning spray. CO2 spray used in conjunction with atmospheric plasma and ionized air de-static systems can provide additional surface preparation capability.

CO2 is non-abrasive, won’t cause any damage to the surface, and is a green alternative that is safe for workers. Cool Clean’s CO2 spray cleaning systems are being implemented as an automated tool that integrates into the specific line, requiring no loss of production and improves on efficiency. This waterless cleaning process requires no post drying after the cleaning stage, allowing parts to move directly to a painting/coating step. A multiple nozzle CO2 spray works seamlessly with existing robotics providing complete coverage of the part, ensuring a high quality clean finish.

MAPAL: Machining of Valve Seat and Valve Guide

Modern precision tool provides more production capacity with lower costs at the same time on the machining of Valve Seat and Valve Guide

Machining Task
The machining of the valve seat and valve guide is one of the primary cost drivers during the machining of cylinder heads. Exact angles at the sealing chamfers on the valve seat rings and close tolerances on the concentricity between valve seat and valve guide must be met. In addition to the high geometric requirements, the increasing requirements on the high-temperature stability of the valve seat rings mean that in general very hard and difficult to machine sintered materials are used.

Challenge
The tool concept that meets these requirements while reducing costs at the same time must make use of the most suitable cutting material and have corresponding precision. Cutting material and insert geometry are responsible for the tool life and make a significant contribution to the costs per workpiece. However, the overall design of the tool is also important.

Our Solution

The solution for these tasks is a MAPAL tool with indexable blades and guide pads. It guarantees a qualitatively flawless result due to the high precision of the inserts, the insert seats and the connection in relation to the valve guide. The HX inserts for machining the chamfers on the valve seat ring are of a hexagonal shape and have six cutting edges. Due to a clever arrangement, these inserts can even be used several times for the different chamfers. The precision insert seat in which the HX inserts are mounted makes it possible to change the inserts without any setting process, as all the angles match exactly.

Conversely, all the tools previously used for this machining task require to some extent time-consuming setting work on an insert change. Also it was normally necessary to set the radial run-out on the replacement of the valve guide reamers mounted in the base tool. In the new MAPAL concept the tool for machining the valve guide is now connected using the proven HFS connection. The tool is changed with a radial run-out accuracy of < 5 µm by simply screwing in or unscrewing. This very stable connection also makes it possible to increase the feed rate.

MAPAL Effect
The comparison of the conventional system with the MAPAL solution produces a very clear result. The much higher feed rate and the related cycle time reduction result in a significant improvement in the production capacity, or even in less investment in machinery for new projects. As no setting work is required and it is only necessary to change inserts and tools, there are also significant savings in the area of the non-productive times. However the most important effect on the costs per workpiece is the inserts for machining the valve seat rings. Due to the stable mounting, the right PcBN grade and the ideal cutting edge geometry, the tool lives are increased by five to ten times compared to other systems.

Setting no longer necessary
Five to ten times higher tool lives

 

 

KURT Workholding: Vertical Machining Center Concepts

Vertical Machining, also known as milling, relies on rotary cutters to remove metal from a workpiece. Vertical machining occurs on a vertical machining center (VMC), which employs a spindle with a vertical orientation. With a vertically oriented spindle, tools stick straight down from the tool holder, and often cut across the top of a workpiece.

Vertical Machining Benefits
There are many benefits associated with vertical machining, some of which include:

  • Infinite part shape possibilities due to the 3, 4 or 5 axis capabilities
  • Temperature stability
  • Durability and reliability
  • On-board probing
  • User-friendly CNC controls
  • Efficient and cost-effective pallet changers

Vertical Machining Center Applications
Depending on the job we offer a variety of diverse types of workholding to fit all your vertical machining needs.
