[Processing Example] Counter BTA Processing of Spindle Products

[Processing Example] Counter BTA Processing of Spindle Products

After L1 and BTA, the hole diameter of the treated material will be further enlarged.

Using a head called a counter, we further enlarge the hole diameter of the material that has undergone tempering after L1 and BTA. We carry out processes such as L1, BTA → tempering → L2, BTA → stress relief → L3, BTA at the request of our customers. After the final BTA, honing may also be performed. In that case, honing will be carried out by our partner company, and honing is also very well received.

[Example] Gundrilling process on C1100 tough pitch copper.

[Example] Gundrilling process on C1100 tough pitch copper.

Polishing for gun drill holes (simple honing) is also possible! Examples of gun drilling processing on C1100 tough pitch copper.

As for the processing details, the hole position is quite close to the edge, making it prone to bending due to heat, so I had to be a bit more careful than usual. The discoloration of the copper plate caused by corrosion in the gun drill hole (inner diameter) was addressed with a dedicated polishing (honing) tool for simple honing. 【Case Details】 Material: C1100 (Tough Pitch Copper) Processing: 2-φ9 through holes Quantity: 8 pieces *If you are having trouble with the precision and quality of deep hole machining, please contact Fuji Shin Seisakusho. *Please view the "Production Case Collection" PDF data available for download.

Are you having trouble with deep hole machining (gun drilling)?

Are you having trouble with deep hole machining (gun drilling)?

Deep hole processing of metals and plastics (such as acrylic). We have various sizes available, so please feel free to consult with us.

This is an introduction to deep hole machining (gun drilling). In metals, deep hole machining is often required for cooling water flow paths, air passages such as pneumatic lines, and heater insertion holes. Our company processes deep holes ranging from φ3 to φ30 using gun drilling, providing finished products. Some customers may also request deep hole machining in plastic. Depending on the material and hole size, we may be able to accommodate such requests, so please feel free to consult with us. We have attached a catalog (PDF) with information on hole sizes and machining lengths.

[Case Study] Molds (Injection Molding and Aluminum Extrusion) Industry

[Case Study] Molds (Injection Molding and Aluminum Extrusion) Industry

Introducing a case where cooling performance was improved, gas escape was enhanced, and post-processing was reduced!

We would like to introduce a case study of the production of ultra-fine diameter deep hole components used in cooling channels and gas venting within molds in high-temperature environments. In this case, there were challenges due to a high risk of breakage from the ultra-fine diameter and difficulties in ensuring straightness due to the deep holes. However, through our company's efforts, we improved cooling performance and gas venting, resulting in a reduction in post-processing. Our company has many years of experience and advanced technology in the field of deep hole machining and gun drilling. Utilizing advanced gun drilling technology that enables precise deep hole machining, we provide high-quality processing services tailored to our customers' needs. 【Case Overview】 ■ Industry: Molds (Injection Molding, Aluminum Extrusion) ■ Component Information: DAC material, φ2.1×227.1mm, concentricity 0.04mm, inner diameter ±0.01 to 0.02 ■ Challenges: High risk of breakage due to ultra-fine diameter / Difficulty in ensuring straightness due to deep holes ■ Value Provided: Zero breakage with penetration / Achieved concentricity of 0.04mm / High reproducibility in long holes ■ Technical Points: Carbide drill, step feed, hydraulic control, straightness correction *For more details, please download the PDF or feel free to contact us.
