10 Points to Get Quality Parts, at Shorter Lead Time

  1. Always try to provide proper model and drawing of the part, and make sure drawing is dimension properly and not missing information, Drawings should have all the information to produce a part, Example material, Rev notes, finishing notes. Models should be reference only, 99.9% machine shops convert customer part models to their CAM software, Model data can be lost or changed during conversion to different file formats.
  2. Choose proper tolerance for each feature and select the right material for your project.
  3. Do not assume anything, whatever the requirement is make sure to write in drawing notes or share with manufacturer. 
  4. Any concern or questions should be raised before manufacturer starts machining.
  5. If you require sample parts be flexible with material choice. It will be cost effective and shorter delivery time
  6. CNC Machining Proto type parts will cost more than production run.
  7. Always ask for material, and finishing process certificates also Certificate of conformance to have quality product.
  8. Hire an ISO 9001:2015 certified machine shop only.
  9. Allow enough time for production, Material and quality can be an issue for rush orders.
  10. Understanding manufacturing process is assist, before designing parts or assemblies make sure you understand manufacturing process. If possible, test assemblies with 3D printing.

Multi-Axis CNC Lathes VS Standard 2-Axis Lathes

CNC Lathes came long way, Traditionally Lathes or 2 axis lathes come with X-Axis and Z-Axis only, these CNC lathes are able to do to turning, grooving, threading, drilling and broaching. Before 1990 most of these lathe machines came with tailstock to support the longer parts, and Hydraulic steady rests were very rare on these lathes. Most lathes came with conversational and macro programming options to create the CNC programs on the machine without CAM software. These lathes were made with boxway slides and were able to do bigger depth of cuts. Most of these lathes were with one spindle and one turret only.

  Modern 4 Axis lathes can do all the features what 2 axis lathes are able to do, also modern lathes are offered with multiple spindles, turrets, and hydraulic steady rests. These lathes can do a lot more including Milling, polygon cutting, Keyways, gear or spline cutting, and parts can be synchronized with sub spindle to keep the orientation of keyways or milling features. Parts can transfer between spindles to machine the different features.  These technological advancements made these multi-axis lathe machines very versatile. These machines with proper hardware and software options are able to deliver a lot of work at shorter cycle times. Cam software is required to use these machines to full potential. These machines can be bought or added with CMM probe to measure the parts while running production.
