Parts are complete as they come off the machine providing for improved accuracy
The video shows the capabilities of the Yama Seiki Live Tooling lathe, this includes the following operations for the featured parts:
- Turning
- Boring
- Drilling off center
- Milling and Thread Milling
Operations in both the main and sub spindle.
Parts come off the machine complete, and with less handling of the part. With less handling come improved accuracy.
Here are some of the parts produced in this video

The material is 30% glass filled Peek. Polyether ether ketone (PEEK) is a colourless organic thermoplastic polymer in the polyaryletherketone (PAEK) family, used in engineering applications.
New plastic part requires 5-Axis machining to achieve quality, throughput and tolerance.

PlasTech is manufacturing a new part that we think is quite impressive. It’s a small plastic part only 1.5 high x 1.0 wide with much detail. This part uses the capabilities of the 5-Axis machining and surfacing with tight inside radius tolerances.
The YAMA Sieki GLS-2000LYS lathe is an example of our commitment to invest. It is a 5-axis CNC machining lathe with live tooling and sub spindle.
This is PlasTech second live tooling 5-axis CNC lathe it has purchased within a year.
Plastic CNC machined parts that are normally produced in two and three operations are now completed in one operation thus eliminating tolerance build up, human error and are CNC machined more efficiently. This all translates into a more cost effective process and a higher quality part for the customer.

The YAMA SEIKI GLS-2000LYS 5-axis CNC high speed turning center has 2 types of bed combined with high rigidity, high speed turning capability and compact size which offers high efficiency cutting power for CNC plastic machining. The live tooling turret, Y-axis and sub-spindle allows work on turning, milling, drilling tasks at the same.
The GLS-2000LYS also includes the following features
- 30° slant-bed design provides smooth chip disposal and easier operator access.
- Stainless steel way covers and special steel wipers molded with industrial strength rubber provide durability.
- Fully enclosed splashguards contain chips and coolant for a safe, clean working environment.
- The auto lubrication system delivers metered amounts of lubrication to the slide ways, ball screws, and vital components. Distribution automatically shuts off during idling to prevent waste.
- The extra manual tailstock provides maximum support when turning machining long parts. It can be moved by Z-axis carriage, which manually locks the base and shifts it to the desired position with accuracy and precision.
- Live tooling and C-axis control capabilities on the GLS-1500 series allow the machine to perform multiple tasks on a work piece, such as turning, milling, drilling and tapping. This reduces manpower and cycle time and minimizes loss of accuracy, which can occur when the part is transferred manually.
PLASTECH IS THE ONLY COMPANY THAT CAN PRODUCE THIS VACUUM RELIEF VALVE AT THIS LEVEL OF QUALITY WITH AN ACCEPTABLE COST.
Plastech has recently begun shipping an extremely complex plastic part that will be used in a medical application as a vacuum relief valve.
The vacuum relief valve is manufactured out of black Delrin, and involves several processes that in house at PlasTech including
- CNC Plastic machining using Hurco 5 axis CNC machines
- Component assembly
- Engraving
The vacuum relief valve is manufactured to a high tolerance – 0.0005” – PlasTech is the only company the medical device manufacturer could find who was able to produce the part to a satisfactory level.




Plastech’s Plastic materials expertise allows customers to avoid quality problems

One of Plastech’s long term customers, a multinational company who manufactures cosmetic surgery equipment was having quality problems with a plastic CNC machined component that was being manufactured by a company in China.
The customer turned to PlasTech because of its expertise in plastic CNC machining, and also because PlasTech has a tool set that includes Hurco 5 axis CNC machines.
PlasTech is manufacturing the part in batches of 1,000 using P.E.T. (Polyethylene terephthalate), it was also discovered that the Chinese company had substituted material that was not specified on the drawing!
All in all by having PlasTech manufacture the component, using 5 axis plastic CNC machining, the multinational has eliminated their quality problems and reduced the total cost of procurement.
