Big Demand for Automated ROBOWORKER Drilling Stations
For many years ROBOWORKER has successfully delivered devices for the machining of green parts. There is currently a big demand for the latest version of the automated drilling station RDS. RDS is an efficient and economical alternative to
- cross-hole pressing, which requires a high investment in the machine as well as tooling and development costs that can only be justified with large repeat orders
- manual drilling, in which the machining process is in many cases relatively inefficient due to intensive labor costs and the often high scrap rates.
The RDS is designed for drilling from top and bottom. After the drilling process ROBOWORKER offers a variety of options for cleaning and inspecting the green part. The automation of the machine is based on proven PAG technology with double conveyor belt. In the standard version, the belt offers a buffer for three trays with undrilled parts and three trays with drilled parts.
Which user benefits does the RDS offer? The comparison of cross-hole pressing and drilling of green parts will answer this question.
Cross-Hole Pressing
Only suited for high production volumes
More expensive powder compaction equipment
Substantial engineering required
High tooling costs
Several tooling alterations possibly required
Complex set-up process
Risk of tooling damage and therefore high tooling repair costs
Unbalanced density distribution within the compact possible
Possible distortion of compact during sintering
Drilling of Green Parts
Blank Compaction
Compaction on standard pressing equipment
Standard pressing process
Optimal density distribution in blank
Simple press set-up
Green Drilling
For tangential milling inserts and crankshaft milling inserts
Minimal engineering required
Lowest tooling and engineering costs possible
Short time-to-market
Also suited for small to medium order sizes
Bore-hole geometry can be easily changed by exchanging drill
Minimal distortion after sintering
Separate process step on additional equipment
